Typical Example1. Disconnect all fuel injection lines (3) from the fuel injection pump housing. Put protective caps on fuel line openings and the openings on the fuel injection housing.2. Disconnect control linkage (2).3. Disconnect wires (4). Remove lines (9) and (10) and remove fuel filter and base (7).4. Remove governor control rotochamber (5).5. Remove fuel transfer pump (6).6. Remove the nuts, washers and cover from the timing gear housing. Remove studs (11) if they are damaged or loose.7. Loosen bolt (12) enough to leave a gap of 3.18 mm (.125 in.) between washer (13) and the fuel pump drive gear.8. Install tooling (A) as shown. Tighten the stud to pull the fuel pump drive gear loose from the taper on the fuel injection pump camshaft.9. Remove tooling (A), bolt (12) and washer (13) from the engine.10. Fasten a nylon strap and hoist to the fuel injection pump housing and governor (1).11. Remove bolts (8) and the nuts that hold the fuel injection pump housing to the timing gear plate. Remove fuel injection pump housing and governor (1). Weight is 29 kg (64 lb.).Install Fuel Injection Pump Housing And Governor
Typical Example
Typical Example1. Put clean engine oil on the O-ring seals. Install O-ring seals (14) in the bottom and O-ring seals (15) in the front of the fuel injection pump housing and governor.2. Make sure O-ring seals (14) and (15) stay in position in the fuel injection pump housing and governor. Fasten a hoist to the fuel injection pump housing and governor, and put it in position on the engine. Install the bolts at location (8) and the nuts on studs (11) to hold the fuel injection pump housing and governor in position.3. Remove the bolts that hold cover (16) in position. Remove cover (16) and, the gasket.
Typical Example4. Put tool (A) in position as shown. Install the bolt that holds the fuel pump drive gear to the fuel injection pump camshaft without the washer. This will allow the camshaft in the fuel system to be turned.5. Put pressure on the end of tool (A) and turn the camshaft slowly until the tool drops in the groove (slot) in the camshaft. Leave tool (A) in position in the groove (slot). Remove the bolt from the end of the camshaft. 6. Install washer (13) with the large diameter toward the front of the engine. Install bolt (12) and tighten it to a torque of 6.8 N m (60 lb.in.).7. Install tooling (B) as shown in the flywheel housing. Make sure bolt (12) does not loosen as the flywheel is turned.8. Use tooling (B), and turn the flywheel in the direction of engine rotation until bolt (17) [3/8" - 16 NC x 4 in. (102 mm)] can be installed in the flywheel. Do not turn the crankshaft counterclockwise to get bolt hole alignment.9. If you go past the bolt hole in the flywheel, turn the crankshaft counterclockwise, opposite the direction of the engine, (as seen from the front of the engine) approximately
