Removal of Gear Case or Front Plate
Note: The camshaft must be removed before the gear case /
front plate can be removed. See "Inspection of Camshaft" on
page -146
1. Remove the oil pump.
NOTE:
It is not necessary to remove the fuel injection
pump from the gear case / front plate to remove
the gear case / front plate. If the fuel injection
pump does not need to be repaired, leaving it
mounted to the timing gear case / front plate will
eliminate the need to re-time it during assembly.
See "Fuel Injection Pump" on page -180
2. Remove the bolts (4, Figure 178).
3. Remove the gear case (1, Figure 178) or front plate from
the cylinder block. Thoroughly clean all old sealant from
the mating surfaces.
4. Inspect and measure the camshaft bushing.
"Camshaft" on page -97 for the service limit. If damaged
or worn beyond service limits, remove the camshaft
bushing (3, Figure 178).
