INSTALLER A- 5P7294 - Caterpillar

Pressure Tap Test Ports
Note: All pressures are taken at 2000 rpm and 51°C (123°F) average.18. If the pressure does not agree with the chart, adjust the pressure using the following procedure.
(7) 4M-1751 Spacer and 5J-1036 Shim.(8) Adjuster assembly.(9) Locknut.(10) Adjustment screw.a. Loosen the locknut (9) on the adjuster assembly (8).b. While monitoring the pressure, adjust by turning the adjustment screw (10). To lower the pressure, turn the adjustment screw clockwise. Total adjustment screw range is approximately 132 kPa (19 psi).c. Tighten the locknut (9) to 25 4 N m (18 3 lb ft). Shift the transmission to NEUTRAL for a minimum of 15 seconds and then shift the transmission back to the gear specified in Steps 9 through 17. Confirm that the pressure agrees with the "Initial Pressures" chart.d. If the pressure cannot be adjusted to within the acceptable limits with the adjusting screw (10), stop the engine and remove the solenoid manifold to access the selector spool. Remove the selector spool and add or remove shims and spacers as required. e. Install the solenoid manifold and adjust the initial pressure according to Steps a through c in Step 18.19. Continue the procedure until all the stations (pressure taps) are checked and adjusted.20. Stop the engine, remove the transmission valve and install the original 8E-9474 Cover.21. Use new 9P-9150 Washers and install the control group on the transmission. Tighten the mounting bolts (4) to 30 4 N m (22 3 lb ft).22. Attachment the wiring harnesses (3) and the manual modulation cable.23. To verify the clutch pressures, follow Steps 4 through 12 in "Check Transmission Clutch Pressure".24. Install guards and differential drive shaft. This procedure should be followed whenever a transmission control valve is repaired by replacing any of the springs or spools contained within the individual clutch stations. If the transmission clutch pressure (steady state) is out of range, the most likely cause of the failure will be a failed modulation spring, debris in control valve or a seal failure within the transmission.Check Transmission Lubrication Pressure
1. Operate the machine until the transmission oil is at operating temperature of 50°C (122°F).2. Stop the machine on a hard level surface. Engage the parking brake. Turn the engine OFF. 3. Remove plug (1) from the transmission case. Install a nipple and a 1000 kPa (145 psi) pressure gauge into the pressure port.4. Start the engine and operate the engine at low idle. The gauge pressure should read 80 30 kPa (12 4 psi).5. Operate the engine at high idle. The pressure on the gauge should be a minimum of 340 kPa (50 psi).6. Remove the differential drive shaft. Operate the machine in FIRST/FORWARD at LOW idle. The gauge pressure should be a minimum of 7 kPa (1 psi).7. Operate the machine in FIRST/FORWARD at HIGH idle. The gauge pressure should read 241 27 kPa (35 4 psi).8. Operate the machine in NEUTRAL at HIGH idle. The gauge pressure should read 558
