GUARD AS-LH 1056244 - Caterpillar

Fluid Spillage ContainmentCare must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to "Tools And Shop Products Guide", NENG2500 for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose fluids according to local regulations and mandates. The transmission oil pump can be removed from the transmission case at any time except in chassis. The following illustrations shown are for better photo illustration.
Typical Example1. Remove covers (1) and (2) from the transmission oil pump. Remove seven bolts (3) that hold the transmission oil pump to the transmission case.
Typical Example2. Install two bolts (3) and use them as forcing screws to separate the pump from the transmission housing. Remove the transmission oil pump. 3. Remove bolts (4) and plate (5). Remove splined input shaft (6) from the pump housing. 4. Remove retainer ring (7) from the groove in the gear shaft. 5. Install Tooling (A) through the holes in gear (8). Pull gear (8) off of the gear shaft. 6. Remove bearing from gear (8) if necessary. 7. Remove bolts (10) and (14) from pump bodies (12) and (13). 8. Remove gear assemblies (16) from pump body (12).9. Remove O-ring seal (15) from the pump body. 10. Inspect bearings (17). Remove them from pump body (12) only if necessary. 11. Inspect bearings (18). Remove them from pump body (13) only if necessary. The following steps are for the assembly of the transmission oil pump
Typical Example Of Bearing Installation12. Install bearings (18) in pump body (13) with a suitable driver.13. The bearing joint is 30 15 degrees from the centerline as shown. The depth from the top of the bearing to the pump body surface is 1.5 0.5 mm (.059 .020 in). 14. Install bearings (17) in pump body (12) with a suitable driver.15. The bearing joint line is 30 15 degrees from the centerline as shown. The depth from the top of the bearing to the pump body surface is 1.5 0.5 mm (.059 .029 in). 16. Install gear assemblies (16) in pump body (12). Lubricate and install a new O-ring seal (15). 17. Install pump body (13) on pump body (12). 18. Install bolts (10) and (14) that holds pump bodies (12) and (13) together. 19. Install a new bearing (9) in gear (8) if it had to be removed for damage. 20. Install gear and bearing assembly on the gear shaft. Install retainer ring (7). 21. Install splined input shaft (6). Install plate (5) and bolts (4).
Typical Example22. Put the transmission oil pump in position on the transmission case. Install bolts (3) and then install covers (1) and (2) on the transmission oil pump.
