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 Product Guide", NENG2500, for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose fluids according to local regulations and mandates. 1. Remove nuts (2) and remove cover (1) from the timing gear cover. Remove the gasket from cover (1). 2. Remove bolts and washers (3). Remove cover (4). 3. Remove O-ring seals (5) from cover (4). 4. Remove bolts (6). Remove ring (7) and the gear. 5. Remove fuel injection lines (9). Put caps and plugs on the openings of the pump and lines to prevent contamination from entering the fuel system.6. Remove tube assembly (8). Remove tube assemblies (11) and fuel manifold (10). Remove fuel transfer pump (12). 7. The weight of the fuel injection pump housing and governor is approximately 57 kg (126 lb). Attach a hoist to the fuel injection pump housing, and remove two bolts (16), and two bolts (17).8. Remove two nuts (13) and bolt (14). Remove fuel injection pump housing and governor (15). 9. Remove O-ring seals (18) from fuel injection pump housing (15). The following steps are for the installation of the fuel injection pump housing and governor.10. Attach a hoist to the fuel injection pump housing aad governor (15). Be sure that the three O-ring seals are in position on the fuel injection pump housing. Install the fuel injection pump housing and governor on the timing gear housing.11. Install fuel transfer pump (12) and fuel manifold (10). Install tube assemblies (8) and (11).12. Install fuel injection lines (9). 13. Put gear (19) in position in the front timing gear cover. 14. Install two 3/8 -16 NC × 152.4 mm (6 in) long guide bolts (20) in gear (19) as shown. 15. Install ring (7). Install two bolts (6) finger tight. Remove the guide pins and install the remaining bolts (6). Tighten bolts (6) to a torque of 3 N m (27 lb in).16. Put the O-ring seals on cover (4). Lubricate the seals with clean engine oil. Put cover (4) in position on ring (7) and install bolts and washers (3). 17. Put the No. 1 piston at top center on the compression stroke. Make reference to the topic "Finding Top Center Compression Position For No. 1 Piston", in the Systems Operation, Testing & Adjusting Manual. Remove the timing bolt from the flywheel, and use Tool (A) to rotate the crankshaft clockwise (opposite the direction of engine rotation) 45 degrees. 18. Remove the plug from the fuel injection pump housing. Install Tool (B) in the fuel injection pump housing as shown. Slowly rotate the crankshaft counterclockwise (direction of engine rotation) until the timing pin goes into the slot in the fuel injection pump camshaft.
Too much pressure on the timing pin can damage the fuel injection pump or the timing pin.
19. Put the timing bolt in the timing hole in the flywheel housing. Rotate the crankshaft counterclockwise (as viewed from the flywheel end of the engine) until the fuel pump camshaft is tight against Tool (B). This removes gear clearance from the drive train. If the bolt can be installed in the timing hole in the flywheel, the timing of the fuel injection pump is correct.20. If the timing bolt does not go into the timing hole in the flywheel, the timing is not correct. Do the steps that follow to adjust the fuel injection pump timing; a. Loosen four bolts (6). With Tool (B) installed and the timing bolt removed, turn the flywheel clockwise (opposite the direction of engine rotation) a minimum of 45 degrees. This removes the backlash from the timing gears when the engine is put on top center (TC).b. Tighten two bolts (6) 180 degrees apart, evenly to a torque of 3 N m (27 lb in).c. Turn the flywheel slowly in the direction of engine rotation until the timing bolt can be installed in the flywheel. The No.1 piston of the engine is now at top center (TC).d. Tighten four bolts (6) to a torque of 55 7 N m (41 5 lb ft). Remove the timing bolt from the flywheel and Tool (B) from the fuel injection pump housing.21. Turn the flywheel clockwise (opposite the direction of normal engine rotation) a minimum of 45 degrees. Now, turn the flywheel in the direction of engine rotation until Tool (B) drops into the slot of the pump camshaft. Now turn the flywheel more, in the direction of normal engine rotation, until all gear clearance is removed from the drive train. Check to see that the timing bolt will go into the flywheel.22. If the timing is not correct, do the procedure in Steps 20a through 20d again.23. If the timing is correct, remove the timing bolt from the flywheel and the timing pin [Tool (B)] from the fuel injection pump housing. Install cover (1) and the plug in the fuel injection pump housing.
