start by:a) disassemble governorb) remove fuel injection pumps 1. Remove cover (1) from the fuel injection pump housing. 2. Remove rack (2) from the fuel injection pump housing. 3. Remove the lifters (3) from the fuel injection pump housing. 4. Put the fuel injection pump housing on end on blocks and use tool (A) to remove snap ring (4) from the camshaft. 5. Use a soft hammer to push the camshaft toward the governor end of the fuel injection pump housing to loosen washer (5) on the camshaft. Remove washer (5). 6. Remove camshaft (6) from the fuel injection pump housing. 7. Remove bearings (7) from the drive end of the fuel injection pump housing. 8. Remove bearings (8) from the governor end of the fuel injection pump housing.Assemble Fuel Injection Pump Housing
Be sure all oil passages are clear and put clean oil on all parts before assembly. 1. Use tooling (A) to install bearing (2) in the governor end of the fuel injection pump housing with junction (joint) (3) toward the top of the fuel injection pump housing. Install the bearing so it is 0.25 0.20 mm (0.10 0.008 in.) below the surface of the housing.2. Use tooling (A) to install bearing (1) in the governor end of the fuel injection pump housing so it is 7.16 0.13 mm (0.282 0.005 in.) below the surface of the housing. 3. Use tooling (A) to install bearing (4) in the drive end of the fuel injection pump housing with the junction (joint) in the bearing toward the top of the fuel injection pump housing. Install the bearing so it is 1.00 0.25 mm (0.039 0.010 in.) below the surface of the housing. 4. Install plate (6) of tooling (C) on the drive end of the fuel injection pump housing to install the bearing for the rack. Use clean grease to hold the new rack bearing on driver (5) of tooling (C). Install the driver and bearing in plate (6) with the groove in the driver in alignment with the pin in the plate and use a hammer to push the bearing into position. The bearing will be installed to the correct depth when the shoulder of the driver is against plate (6).5. Remove tooling (C) from the fuel injection pump housing. The rack bearing must be installed so it is 0.25 0.25 mm (0.010 0.010 in.) below the surface of the housing. 6. Install camshaft (7) in the fuel injection pump housing.7. Put the fuel injection pump housing on end and put a block under the camshaft. 8. Put washer (9) over the end of the camshaft and use tooling (A) and a spacer (8) that has an inside diameter of 38.1 mm (1.5 in.) and a length of 31.75 mm (1.25 in.) to push the washer against its seat on the camshaft. Camshaft must have 0.285 0.235 mm (0.0112 0.0093 in.) end play when washer is pushed against
