    Introduction This special instruction provides the information to adjust the main pump relief pressure on HydraCrowd equipped 7495 and 7495HF Electric Rope Shovels.

    Important Safety Information

    STORED ENERGY! Hydraulic pressure must be relieved prior to performing this procedure. Hydraulic fluid under pressure may cause injury or death if not released in a controlled manner.

    Required Tooling

    TOOLS:

    6 mm Allen Key

    2 mm Allen Key

    19 mm Wrench

    1. Set the dipper flat on the ground and lower the hoist until the padlocks are

    down and the hoist ropes are slack.

    SIS Media Number: BI646626 Media Number: SA13-025

  • Illustration 1: Padlocks Lowered

    2. Shutdown the machine. Lockout and tagout controls in compliance with

    local regulations.

    3. Install a 0-8000 psi pressure gauge on the pressure outlet test port of each main pump. It is ideal to monitor all 4 pumps at the same time (digital pressure gauge in the S127020 commissioning kit has this capability).

    Illustration 2: Preesure Outlet Test Ports

    4. To adjust individual pump relief pressure, remove the cylindrical relief

    valve cover (See Illustration 3 for location).

  • 6. Once the relief valves are exposed, remove lockout tagout from machine controls.

    7. Start the machine.

    8. Access the HydraCrowd Commissioning Screen from the operators display in the operator cab (see Illustration 5).

    9. Turn crowd control on

    10. Energize the PICV Output button

    11. Choose the valve position (1-4) you would like to test and press the

    corresponding PUV button.

    12. Press the Run Crowd Motor at 20% reference button. The chosen PUV will now be forced over relief.

  • IMPORTATNT: If the following steps do not affect the pump outlet pressure, it will be important to return the relief to its original setting. Before turning the adjusting screw, mark the screw location with respect to the valve body. As the adjusting screw is turned count the number of rotations so it could be returned to original.

    13. In the machinery house, with pump pressure going over relief, slowly turn the adjustment screw while observing the pump pressure associated with the relief valve (see Illustrations 6 and 7 for pump and corresponding relief locations). Turning the screw clockwise will increase the relief pressure, turning the screw counterclockwise will reduce the pressure.

    14. When the gauge pressure reads 3700 psi 50 psi tighten the jam nut to secure the adjusting screw. Recheck pressure setting after tightening the jam nut to ensure the setting hasnt changed.

    19 mm Wrench

    NOTE: If gauge pressure does not change when the adjustment screw is turned,

    return the adjustment screw to its origional position.

    15. Install the cylindrical cover onto the relief and secure with screw.

    2 mm Allen Key

    16. Remove pressure gauges from the pump outlet ports and reinstall test port covers.

    17. Ensure cylinder speed is normal by stroking the cylinder several times in the horizontal position. Verify by observing cylinder speed on the operator HMI screen. Extend speed is approximately 130 ft. /min while retract is approximately 120 ft. /min.

    STEPS 4 & 5(INITIAL TORQUE SEQUENCE)STEPS 6 & 7

    STEP 9STEP 8

    INSTALLATION NOTES: MAKE SURE SPECIAL STEEL WASHERS SUPPLIED WITH TORQUENUTS ARE USED UNDER EACH TORQUENUT - DO NOT USE STANDARD COMMERCIAL WASHERS.

    AN IMPACT WRENCH MAY BE USED FOR THE INITIAL RUN UP, BUT A TORQUE WRENCH MUST BE USED FOR THE FINAL VALUES.

    INSTALLATION PROCEDURE: STEP 1: JACKBOLT THREADS & END FACES ARE PRE-LUBRICATED BY VENDOR WITH GRAPHITE LUBE. ENSURE THAT GRAPHITE LUBE FILM IS PRESENT ON THESE SURFACES AND APPLY ADDITIONAL GRAPHITE LUBE (MP390331) AS NEEDED.

    STEP 2: CHECK BASE OF TORQUENUT TO ENSURE THAT ALL JACKBOLTS ARE FLUSH WITH BOTTOM.

    STEP 3: LUBRICATE THE THREADS OF THE MAIN STUD WITH ANTI-SEIZE LUBRICANT.

    STEP 4: SLIDE THE HARDENED WASHER ONTO THE STUD, THEN SPIN THE TENSIONER ONTO THE MAIN THREAD UNTIL IT SEATS AGAINST THE WASHER.

    STEP 5: BACK OFF THE TENSIONER TO LEAVE A GAP OF .06-.12 FOR LUBRICATION DURING REMOVAL.

    STEP 6: USING A SUITABLE TORQUING DEVICE, TIGHTEN (4) JACKBOLTS AT 90 APART (SEE FIGURE TO RIGHT FOR SEQUENCE) ON ALL STUDS WITH A PARTIAL TORQUE (30-70%, 8-19 LB-FT).

    STEP 7: AT 120% TARGET TORQUE (33 LB-FT), TIGHTEN THE SAME (4) JACKBOLTS ON ALL STUDS.

    STEP 8: AT 120% TARGET TORQUE (33 LB-FT), TIGHTEN ALL JACKBOLTS IN A CIRCULAR PATTERN. DO THIS FOR ALL STUDS (1 ROUND ONLY).

    STEP 9: SWITCH TO A TORQUE WRENCH AND TIGHTEN ALL JACKBOLTS TO 100% TARGET TORQUE (27 LB-FT) IN A CIRCULAR PATTERN UNTIL ALL JACKBOLTS ARE STABILIZED (LESS THAN 10 ROTATION). THIS USUALLY REQUIRES 2-4 ADDITIONAL PASSES.

    REMOVAL PROCEDURE: PREPARATION: SPRAY JACKBOLTS WITH PENETRATING OIL OR HYDRAULIC OIL PRIOR TO START.

    STEP 1: LOOSEN EACH JACKBOLT 1/8 TURN FOLLOWING A CIRCULAR PATTERN AROUND THE TENSIONER (1 ROUND ONLY). AS YOU MOVE AROUND AND GET BACK TO THE FIRST JACKBOLT, IT WILL BE TIGHT AGAIN. DO THIS FOR ALL STUDS ON THE JOINT PRIOR TO THE NEXT STEP.

    STEP 2: REPEAT A 2ND ROUND AS ABOVE FOR ALL STUDS, NOW LOOSENING EACH JACKBOLT 1/4 TURN IN A CIRCULAR PATTERN.

    STEP 3: CONTINUE LOOSENING 1/4 TURN FOR 3RD AND SUCCESSIVE ROUNDS UNTIL ALL JACKBOLTS ARE LOOSE. NOTE: USUALLY AFTER THE 3RD OR 4TH ROUND, AN IMPACT TOOL CAN BE USED TO COMPLETELY EXTRACT THE JACKBOLTS, ONE BY ONE. FOR LONG BOLTS OR TIE RODS, ADDITIONAL ROUNDS MAY BE REQUIRED BEFORE REMOVING THE JACKBOLTS WITH AN IMPACT TOOL.

    STEP 4: REMOVE, CLEAN AND RELUBRICATE THE JACKBOLT THREADS AND TIPS PRIOR TO NEXT USE WITH CORRECT SUPERBOLT LUBRICANT (MP390331).

    CAUTION! JACKBOLTS MUST BE UNLOADED GRADUALLY. IF SOME JACKBOLTS ARE FULLY UNLOADED PREMATURELY, THE REMAINING JACKBOLTS WILL CARRY THE ENTIRE LOAD AND MAY BE HARD TO TURN. WITH EXTREME ABUSE, A JACKBOLT TIP CAN DEFORM, MAKING REMOVAL DIFFICULT.

    STUCK JACKBOLT REMOVAL: IF A JACKBOLT WILL NOT TURN, REMOVE, RE-LUBE, AND RETIGHTEN A NEIGHBORING JACKBOLT. THEN TRY TO TURN THE STUCK JACKBOLT.

  • BOMBA DE PALETAS

    Jose Manuel Arroyo Rosa Pgina 1

    Bombas de Paletas

    Bombas de paletas:

    Se compone de un rotor que gira dentro de una carcasa y de las paletas que se encuentran en unas ranuras que tiene el rotor, con posibilidad de desplazarse

    radialmente.

    Se dividen en dos grupos, bombas de una carrera y bombas de dos carreras. Oscilan entre 5 y 100 cm. Pueden ofrecer presiones de servicio de hasta 150

    bar.

    Son muy sensibles al nivel de limpieza del aceite. Un aceite con partculas en suspensin podr originar una avera en la bomba.

    Bombas de paletas de una carrera:

    El rotor esta descentrado de la carcasa.

    Al girar succiona el fluido desde la entrada de la bomba, generando al girar unos

    espacios o cmaras entre las paredes del rotor, del estator y las paletas.

    Cuando este espacio comienza a comprimirse la bomba deja salir el fluido por el

    orificio de salida

    .

    Las paletas salen radialmente, apoyndose en la carcasa.

  • BOMBA DE PALETAS

    Jose Manuel Arroyo Rosa Pgina 2

    La forma de salir es debida a la entrada de aceite dentro del rotor, asegurando en todo

    momento que la paleta apoya en la carcasa.

    Bomba de paletas de dos carreras:

    Estas bombas tienen una carcasa o estator ovalado o doble excntrico.

    Con dos entradas y dos salidas, se sita un estator de palas en el centro, generando dos

    zonas de cmara amplia.

    El resto del funcionamiento es similar al de la bomba de paletas de una carrera, con la

    diferencia de que realiza dos procesos por cada ciclo.

    .

  • BOMBA DE PALETAS

    Jose Manuel Arroyo Rosa Pgina 3

    El volumen de las cmaras en una bomba de paletas lo determinan las dimensiones del

    anillo excntrico y la medida transversal.

    Bomba paletas Vickers de doble paleta y dos carreras

    Bomba de paletas de caudal variable:

    El funcionamiento de esta bomba consiste en desplazar el estator de tal forma que

    variamos la excentricidad entre el rotor y el estator.

    De esta manera variamos el caudal de la bomba, variando el volumen de las cmaras.

    Estas bombas son de una sola carrera y disponen de tres dispositivos de

    posicionamiento.

    Tornillo de posicionamiento para cilindrada (9). Tornillo de ajuste de altura (2). Tornillo de ajuste de mxima presin (7).

    Si la fuerza Ff que es la que produce el muelle (6), es mayor que la fuerza Fh, el estator

    de la bomba permanece en su posicin excntrica segn la figura.

    A medida que aumenta la presin en el sistema, aumenta tambin la fuerza Fh y la

    vence el resorte desplazando el estator a una posicin concntrica.

  • BOMBA DE PALETAS

    Jose Manuel Arroyo Rosa Pgina 4

    El volumen de las cmaras de desplazamiento se reduce hasta que el caudal a la salida

    de la bomba sea nulo.

    La bomba mantiene la presin en el circuito segn tengamos ajustados los tornillos de

    regulacin.

    Estas bombas pueden ser de mando directo, como la que hemos explicado, o pilotadas.

    Estas ltimas no varan mucho de las de mando directo, solo en que el dispositivo de

    pilotaje que emplean para variar el estator se mueve mediante pistones de

    posicionamiento cargados previamente con presin.

    Estos pistones tienen diferente dimetro, siendo el ms grande el que se dedica que la

    bomba se encuentre en una posicin excntrica.

    Datos para el clculo del caudal de una bomba de paletas:

    Q = D(D-d)bn/1000000

    Q : Caudal terico en l/min.

    D : Dimetro de la cmara interior de la carcasa en mm.

    d : Dimetro del rotor en mm.

    b : Ancho de la paleta o la cmara en mm.

    n : velocidad de giro del engranaje en rpm.

    El rendimiento volumtrico de este tipo de bombas es de 0,8 aproximadamente, por lo

    que el Qreal ser:

    Qreal = Qterico 0,8

  • ContaminationSensor CS1000 Cleanliness classes - brief overview

    Cleanliness classes - brief overview

    Cleanliness class - ISO 4406:1999

    For ISO 4406:1999 particle counts are determined cumulatively, i.e. > 4 m(c), >6 m(c) and >14 m(c) (manually by filtering the fluid through an analysis membrane or automatically using particle counters) and allocated to key figures.

    The goal of allocating particle counts to references is to facilitate the assessment of fluid cleanliness.

    In 1999 the "old" ISO 4406:1987 was revised and the size ranges of the particle sizes to be analyzed were redefined. The counting method and calibration were also changed.

    Important for the user in his everyday work: Even though the size ranges of the particles to be analyzed have changed, the cleanliness code will change only in individual cases. When the "new" ISO 4406:1999 was created, not all the existing cleanliness provisions for systems were changed.

    Caterpillar Global Mining LLC 6744 S. Howell Ave Oak Creek, WI 53154, USA 414.768.4000 / Fax: 414.768.4570

    Date: November 19, 2012

    Advisory No.: 12-006 Revision No.: 1

    MANDATORY Compliance with this advisory is mandatory. Failure to do so may result in machine failure.

    SUBJECT: HYDRAULIC CROWD ACCUMULATOR INSPECTION & PRESSURE TEST

    NOTE: IT IS ESSENTIAL THAT ALL APPROPRIATE SAFETY MEASURES SUCH AS THOSE SET FORTH IN THE APPLICABLE MACHINE MAINTENANCE MANUAL ARE FOLLOWED DURING THE PERFORMANCE OF THIS WORK.

    MODELS AFFECTED: 7495, 7495HF (HydraCrowd equipped machines only)

    MACHINES AFFECTED S/Ns: 141209, 141325, 141327, 141333, 141418, 141424, 141429, 141433, 141439, 141441, 141452, 141455, 141463, 141469, 141470, 141473, 141474, 141477, 141481, 141482

    Problem: Correct accumulator charge is critical to maintain proper operation of the hydraulic crowd system. Acceptable pressure is 900 psi (+15 psi / -0 psi) at 20 C.

    Action: It is recommended that the proper gas pre-charge is checked at the next available maintenance opportunity. After that, it should be checked according to the following intervals:

    If accumulator pressure monitoring system is installed The proper gas pre-charge pressure should be verified after each new installation or repair. The proper gas pre-charge pressure should be checked using the operators display every 500 hours or monthly which ever occurs first. The system should be verified to be functioning correctly every 6 months by comparing the actual accumulator charge pressure on the operator's display to the pressure reading on the charging/gauging unit.

    If accumulator pressure monitoring system is not installed The proper gas pre-charge pressure should be set after each new installation or repair. It should be rechecked at least once during the first week of operation. It should be rechecked again every 500 hours or monthly, which ever occurs first.

    See Accumulator Inspection section and Accumulator Pressure Test & Charge section in Service Manual

    The acceptable pre-charge pressure is dependant on the ambient air temperature. At 20 C, the correct pressure is 900 psi (+15 psi / -0 psi). When charging an accumulator, ensure it is filled to the correct pressure based on the ambient air temperature. See table below for correct charge pressure.

    Additional Information

    In order to check the pressure, only the gauging unit is required. There is a check valve at the connection for the charging hose, so the accumulator will not lose its charge if a nitrogen bottle isnt connected. Ensure the bleed valve is closed when checking the charge pressure.

    There should not be any interference issues connecting the gauging unit to the CRGV accumulator.

    RECV Accumulator Mounting (Lot 183 and Newer)

    The accumulator mounting bracket is tilted so the charging/gauging unit will not interfere with the RECV module located above the accumulator when attached.

    Previous RECV Accumulator Mounting (Lot 181 and Older)

    The accumulator mounting bracket is straight, so the gauging unit will interfere with the RECV module when trying to check the pressure. In order to check the pressure, the lower bolt holding the accumulator to the bar will need to be loosened and the upper bolt will need to be removed. Then, the accumulator can be tilted away from the RECV module so the gauging unit can be installed. Ensure the upper bolt is re-installed and both bolts are tightened after accumulator charge is checked.

    9.5.9 Accumulator InspectionThe condition of the accumulator is primarily determined by periodic checking of the pre-chargepressure. To check the gas precharge pressure in an accumulator, it must first be isolated fromthe system, using the shut off and bleed valve. The most accurate pre-charge readings are takenwhen the hydraulic oil pressure is at 0.

    9.5.9.1 Intervals Between Checking Gas Pre-charge PressureIf accumulator pressure monitoring system is installed:The proper gas precharge pressure should be verified after each new installation or repair. Theproper gas precharge pressure should be checked, using the operators display, every 500 hoursor monthly, whichever comes first. The system should be verified to be functioning correctlyevery 6 months by comparing the actual accumulator charge pressure on the operator's displayto the pressure reading on the charging/gauging unit.

    If accumulator pressure monitoring system is not installed:The proper gas precharge pressure should be set after each new installation or repair. It shouldbe rechecked at least once during the first week of operation. It should be rechecked again every500 hours or monthly, which ever occurs first.9 50 Electric Rope Shovel SM141494-ENNovember 2012

    9.5.10 Accumulator Pressure Test & Charge

    STORED ENERGY! Hydraulic accumulators are pressure vessels and only qualified personnel should perform repairs or maintenance. NEVER use oxygen (or compressed air) to precharge the accumulator! Use dry nitrogen only.

    NOTE: This procedure can be performed with the dipper handle in either the horizontal position (Option A) or the vertical position (Option B). If performing this procedure with the bucket in the air (Option A), manually engage the optional hoist maintenance locking bar (if equipped) as a secondary safety device. With the dipper handle positioned horizontally, the cylinder and sleeve assembly can be reached from the machinery house. With the dipper handle positioned vertically, a man-lift will be required to reach the cylinder and sleeve assembly. Regardless of which option the machine is positioned, ensure that service personnel have proper PPE and fall protection required to do their job safely.

    NOTE: Both hydraulic crowd accumulators (RECV and CRGV) should be set to the same parameters.

    0,SIS Media Number: BI646664Hydraulic Crowd Service ProceduresInspection BI010733 To pressure test and/or charge the accumulator:

    1. Position the machine for service using option A or B.

    Option A

    Position the handle so the accumulators can be accessed from the house roof. Use the crowd motion to position the hoist ropes as close to vertical as possible in order to

    minimize the force (pulling out or pushing in) the hoist ropes exert on the cylinder. The rodend pressure can be monitored from the operator cab screen to ensure the hoist rope forceon the cylinder is minimized.

    Option B

    Place the dipper on the ground.

    2. Shutdown the machine. Lockout and tagout controls in compliance with local regulations.3. Verify that the rod end of the cylinder is void of pressure by bleeding excess oil pressure

    from the rod end test port on the cylinder manifold. This can be achieved by attaching amicro bore hose from the hydraulic test kit and emptying the oil into a bucket or otherstorage vessel. This may take several minutes. Once pressure is relieved, remove themicro bore hose from the test port and install a pressure gauge to verify no pressure ispresent.9 52 Electric Rope Shovel SM141494-ENNovember 2012

    To determine correct charge pressure with varying ambient air temperatures use the chart below.

    12. If the gas pressure is low, charge the accumulator until the correct pressure is reached. Thecharging process should be done very slowly to ensure that the accumulator is notdamaged. With accumulator pressure monitoring system installed, charge to 900 psi (+15psi / -0 psi) as shown on the operators display as the Temperature Corrected Value.Without accumulator pressure monitoring system installed, charge to the pressure shown inthe chart above based on the current outside ambient temperature.

    If the accumulator is new or has fallen below 100 psi, the accumulator must be charged at a very slow rate. It should take 2-3 minutes for every 20-30 psi. Charge at this rate until the accumulator pressure reaches 100 psi. Above 100 psi, the rate of charging can increase to 100 psi per 2-3 minutes until the system is fully charged to the correct pressure.

    13. Allow 10 minutes for the gas temperature and pressure to stabilize. Recheck and adjust asnecessary.

    14. If the gas precharge is still low, continue charging. If the gas pressure is high, bleed gas offthrough the charging system. Allow 10 minutes for the gas temperature and pressure tostabilize.

    15. If accumulator is unable to maintain charge, replace accumulator.16. Once the proper gas precharge pressure is reached, close the shut-off valve on the nitrogen

    bottle and tighten the charging cap screw on the accumulator by rotating the T-handle. Thiswill seal the gas in the accumulator. Loosen the adapter and disconnect the charging/gaugeunit from the accumulator.

    17. Using an allen wrench, tighten the charging cap screw to 15 Ft-Lbs and check the areaaround the screw for leaks using a soapy solution. If any leaks are found, repair or replaceSM141494-EN Electric Rope Shovel 9 55November 2012

    HydraCrowd Initial Start-up Procedure

  • Caterpillar Confidential: YELLOW / WHEREVER THERES MINING. 2

    HydraCrowd Initial Start-up Procedure

    This procedure is to be used when the system is started for the first time, when the oil has been drained and re-filled, or after a major repair procedure has been completed.

    An electrical engineer may be required to force the PLC to advance or remain in the heating mode.

    The S127020 HydraCrowd Commissioning Tool Kit contains the pressure gauges required to take the required measurements listed below.

    Section 9 of the Maintenance Manual contains additional information related to HydraCrowd Servicing.

    NOTE: IT IS ESSENTIAL THAT ALL APPROPRIATE SAFETY MEASURES SUCH AS THOSE SET FORTH IN THE APPLICABLE MACHINE MAINTENANCE MANUAL ARE FOLLOWED DURING THE PERFORMANCE OF THIS WORK.

    Procedure

    1. Fill the main hydraulic system with clean hydraulic oil. a. Begin by filling the auxiliary tank (approximately 120 gallons)

    as described in Section 9.6.9 (Auxiliary Power Unit Fill & Filter Replacement) of the Maintenance Manual.

    b. Circulate the oil through the auxiliary unit filters until the contamination monitor reads 16/14/12 or lower.

    c. Transfer the hydraulic oil into the upper tank as described in Section 9.6.6 (System Top Off) of the Maintenance Manual

    d. Repeat steps a, b and c until the hydraulic system is full (approximately 1000 gallons)

    Note: Replace the Pressure, Return and Pre-fill filters as required during the system fill process by monitoring the filter indicators. As the filters become contaminated, the gauge will move from green to red.

  • Caterpillar Confidential: YELLOW / WHEREVER THERES MINING. 3

    2. Fill the PDT with clean gear oil. The transmission holds 5.75 gallons and the cooler core, circulating pump and lines will hold an additional 3.25 gallons. Refer to Section 9.6.10 PDT Initial Oil Fill in the Maintenance Manual.

    3. Purge the 4 main pumps to insure that the 4 pump cases are full of oil. Loosen the hose connection on top of each pump and allow the air to bleed out (Figure 1). When oil is flowing from the fitting, tighten the hose fitting. (See Section 9.9.1 Purging The Main Pumps in the Maintenance Manual)

    Figure 1

    4. Verify correct rotation of the main crowd motor and couple the motor to the PDT. (See Figure 2)

    Note: Turning the pumps in the wrong direction may cause damage to the pumps.

    5. Verify correct rotation of the flushing pump. (See Figure 2) Note: Turning the pumps in the wrong direction may cause damage to the pumps.

  • Caterpillar Confidential: YELLOW / WHEREVER THERES MINING. 4

    6. Verify correct rotation of the circulation pump. (See Figure 2) Note: Turning the pumps in the wrong direction may cause damage to the pumps.

    Figure 2

    7. Start warm-up mode to heat the oil. State 1A will turn the immersion heaters on.

    8. With the warm-up mode in state 1B, the immersion heaters and the circulation pump will be on. Oil will be flowing over the relief valve in the circulation manifold (HOCCV). This will heat the oil. (No oil will be flowing through the crowd cooler.)

    Alternate Method: If the oil in the tank is above 25 degrees C (77 degrees F) force the circulation pump on in the heating mode. The pump should start in low speed and then go to full speed. (This is not always noticeable if the oil temperature in the upper tank is above -7degrees C [20 degrees F].)

    Check the hydraulic oil pressure in the circulation manifold.

  • Caterpillar Confidential: YELLOW / WHEREVER THERES MINING. 5

    Install a 0- 600 psi pressure gauge on outlet pressure port GCP (Figure 3). Expected pressure reading is 400 psi.

    Record the pressure reading __________________ (Spec. is 400 psi.)

    Figure 3

    9. When the oil is warm, the HOCCV will energize and oil will flow through the hydraulic oil cooler and return to the lower tank through the flow meter and circulation filter. (State 2A) This will clean the oil. Check the oil cooler circuit for leaks.

    Alternate method: Force the circulation manifold to go into the cooling mode.

    Observe the flow meter on the right side of the power module. In the cooling mode, the expected pump flow is 90 gpm.

    Record the flow meter reading ______________

    Check the hydraulic oil pressure in the circulation manifold.

  • Caterpillar Confidential: YELLOW / WHEREVER THERES MINING. 6

    Install a 0- 600 psi pressure gauge on outlet pressure port GCP. Expected pressure reading is approximately 120 psi.

    Record the pressure reading __________________ (Spec. is 120 psi if there are 2 crowd oil coolers in series) (Spec. is 150 psi if there are 3 crowd oil coolers in series) (Spec. is 70 psi if there is only one crowd oil cooler)

    Note: Pressures are preset and cannot be adjusted in the field.

    10. Bleed the circulation return oil filter using a Stauff test hose on the test port (Figure 4) on top of the filter housing and run the other end of the test hose into an empty 5 gallon pail. There will be very little flow and very low pressure. Wait until there is a continuous stream of oil and then disconnect the test hose.

    Figure 4

    11. Bleed the crowd cooler core. Air can be trapped in the cooler core. (Optional)

  • Caterpillar Confidential: YELLOW / WHEREVER THERES MINING. 7

    12. Energize the flushing pump. This will turn the contamination monitor (HOCM) on. Check the flushing circuit for leaks. This can be forced on by the electrical engineer, or the crowd control can be turned on.

    Warning: if the crowd control is on, the handle can move if the crowd joystick is moved.

    13. When the flushing pump is running, check the screens on the four flow meters (Figure 5) located on the power module. Insure that they are reading. Expected reading is approximately 2 gpm. There is no need to record the readings at this time.

    Figure 5

    14. Filter the oil in the main system until the cleanliness is 16-14-12 before proceeding. The circulation pump filters the oil when the system is the cooling mode. The flushing pump sends oil through the contamination monitor (Figure 6) and shows the oil cleanliness reading.

    Record the cleanliness reading ________________

  • Caterpillar Confidential: YELLOW / WHEREVER THERES MINING. 8

    Figure 6

    15. When the flushing pump is turned on, the PDT oil pump will move PDT oil through the PDT oil cooler. The PDT oil level may need to be topped off several times until the system is full. Check the PDT oil circuit for leaks. If the oil level is too low, the crowd system will shut down. The operators screen will show a low PDT pressure fault (CDA 218-2).

    Verify the PDT oil level _________

    16. Install a 0- 8000 psi pressure gauge on the outlet pressure port of each main hydraulic pump (Figure 7). It is important to be able to monitor all four pumps at the same time. The Parker digital pressure gauge in the S127020 Commissioning Tool Kit has this capability.

  • Caterpillar Confidential: YELLOW / WHEREVER THERES MINING. 9

    Figure 7

    17. When the oil meets the cleanliness requirement of 16-14-12, run the crowd motor in the Pump Unloaded mode. (State 1C) The crowd motor will turn at 250 RPM. This causes oil to flow from the pumps, through the pump manifold, and back to the upper tank. Check for hydraulic oil leaks. Allow the flushing to continue for at least 15 minutes to insure complete flushing of the pump, hoses and pump manifold.

    18. After step 17, the contamination monitor values may increase, indicating that the system is cleaning the oil. Before proceeding to the next step, continue to circulate the oil until the cleanliness value returns to below 16-14-12.

    Verify that the cleanliness reading on the power module contamination monitor is 16-14-12 or lower and record it here. ______________

    19. Advance the heating mode to State 2B. The main pump heating mode is active. All four PICV solenoids will be turned on. The crowd motor will turn at 250 RPM. Hydraulic oil will be flowing past two PUV valves, back to tank, causing the oil to heat. The PUV valves are turned on and off in pairs to prevent the valves from overheating.

    Each PUV pressure relief valve limits the maximum pressure in its corresponding pump to 3700 psi.

    Alternate method: Force the crowd motor to run at 200 RPM with the 4 PICV valves forced on and PUV 1 and 3 forced on. Check the pressures and adjust if necessary. Then stop the crowd motor and force PUV 2 and 4 on. Run the crowd motor at 200 RPM and check the pressures and adjust if necessary. Record the pressure readings on the chart shown above.

    PUV 1 and PUV 3 are turned on together. Read the pressure on the pump 1 and pump 3 pressure gauges. Expected pressure is 3700 psi.

    Record the Pump 1 pressure reading __________________ (Spec. is 3700 psi.)

    Record the Pump 3 pressure reading __________________ (Spec. is 3700 psi.)

    PUV 2 and PUV 4 are turned on together. Read the pressure on the pump 1 and pump 3 pressure gauges. Expected pressure is 3700 psi.

    Record the Pump 2 pressure reading __________________ (Spec. is 3700 psi.)

    Record the Pump 4 pressure reading __________________ (Spec. is 3700 psi.)

    Note: The individual pressure relief valves (Figure 8) on the pump manifold can be adjusted if required. The pressure relief valve should be replaced if it does not respond when adjusted.

    20. Advance the heating mode to state 2C, manifold heating. Note: this is the same as hose flushing and will clean the hydraulic hoses and manifold. Allow the hose flushing to continue for at least 15 minutes.

    Alternate method: Activate the Hose Flushing Mode using the button on the operators screen. Hose Flushing runs for approximately 15 minutes.

    Record the reading on the 4 pump case drain flow meters (PCDM) at this time.

    Observe the pressure readings of the 4 main pumps on the digital pressure gauge. The expected reading on each pump should be approximately 500 psi. It is not necessary to record the readings.

    21. Record the reading of the contamination monitor at the conclusion of hose flushing. ____________

    22. After step 21, the contamination monitor values may increase indicating that the system is cleaning the oil. Before proceeding to the next step, continue to circulate the oil until the cleanliness value returns to below 16-14-12.

    Verify that the cleanliness reading on the power module contamination monitor is 16-14-12 or lower and record it here. ______________

    23. When the contamination monitor indicates the oil is clean, continue the heating mode until cylinder motion in allowed.

    Alternate method: If the system is not in heating mode, turn on the crowd control and operate the crowd from the operators seat.

    24. Raise the cylinder to the horizontal position.

    25. Bleed the cylinder using Step 4 of the HydraCrowd Cylinder Bleeding Process. (See Section 9.6.1 in the Maintenance Manual)

    26. Operate the cylinder in mid-stroke (between 8 and 15 of crowd extension) until the operational temperature is reached.
