HOUSING-FIXED AXLE 1381687 - Caterpillar

Remove Rear Timing Gears And Plate
start by:a) remove flywheel housingb) remove valve covers 1. Bend the locks away from bolts (1). Remove bolts (1), plate (2) and oil pump idler gear (3) from the back of the flywheel housing. 2. Use tooling (A) and a press to remove bearing (4) from the oil pump idler gear. 3. Bend the locks away from bolts (5). Remove bolts (5) and shaft (6) from the flywheel housing. 4. Remove thrust washers (7) from the flywheel housing. Use tooling (C) to remove bearings (8) from the flywheel housing.5. Turn the crankshaft counterclockwise (as seen from the rear of the engine) to top dead center compression position No. 1 piston. See LOCATING TOP DEAD CENTER COMPRESSION POSITION FOR NO. 1 PISTON in TESTING AND ADJUSTING.6. Install the camshaft timing pins in the right and left inlet camshafts. Remove the fuel injection pump camshaft timing pin from its storage hole, and install the pin in the timing hole in the pump camshaft. 7. Remove thrust washer (9) and cluster gear (10) from the shaft. Remove the other thrust washer from the shaft.8. Remove water pump idler gear (11) and water pump drive gear (12).
To prevent piston and valve contact, do not turn the crankshaft with timing gears removed and the camshafts installed.
9. Use tooling (A) and a press to remove bearing (13) from the cluster gear. 10. Remove cover (14) over the variable timing unit.11. Remove O-ring seals (15). 12. Remove three nuts and washers (16) that hold the water pump to the timing gear plate. 13. Bend the locks away from bolts (18). Remove bolts (17) and (18) and remove rear timing gear plate (19). 14. Remove cage (20) from the back of the timing gear plate. 15. Remove thrust washer (21) from the cage. Use tooling (C) to remove bearing (22) from the cage. 16. Remove oil line (24). Bend the locks away from bolts (23) and remove the bolts. Remove shaft (25) and camshaft drive idler gear (26). 17. Use tooling (B) and a press to remove bearing (27) from the gear.Install Rear Timing Gears And Plate
Put clean SAE 30 oil on all bearings, shafts and gears before assembly. 1. Use tooling (B) and a press to install the bearing in the camshaft drive idler gear. The notches in the bearing must be in alignment with notches (1) in the gear within 2°. The bearing must not extend beyond either face of the gear.
Be sure the oil passages in shaft (3) are clear. Be sure the timing pin is installed in the fuel injection pump camshaft. Be sure the camshaft timing pin is installed in the right and left inlet camshafts. Do not turn the crankshaft with the timing gears removed and the camshafts installed.
2. Put idler gear (2) and shaft (3) in position on the engine and install the lock and bolts that hold the shaft in place. 3. Install oil line (4). 4. Use tooling (A) and a press
