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 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 and governor (15). Be sure that the three O-ring seals are in position on the fuel infection 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 in-16 NC x 152.4 mm (6 in) longguide 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.
