Inspection and Reconditioning
Disassembly
The governor gear must be replaced once it is removed
from the oil pan.
NOTE: The governor gear is held onto the shaft by
small molded tabs in the gear. When the gear
is removed from the shaft, these tabs are
destroyed and the gear must be replaced.
Therefore, remove the gear only if absolutely
necessary.
1. Remove the regulating pin and governor gear
assembly. See Figure 10-13.
Figure 10-13. Removing Governor Gear.
2. Remove the locking tab thrust washer located
under the governor gear assembly.
3. Carefully inspect the governor gear shaft and
replace it only if it is damaged. After removing the
damaged shaft, press or lightly tap the
replacement shaft into the oil pan to the depth
shown in Figure 10-14.

3. Remove the oil pump rotor. If a plastic pickup is
used (See Figures 10-15 and 10-17), unhook the
locking clip, and carefully pull it free from the oil
pump housing.
4. If the relief valve is like that shown in Figure
10-16, drive out the pin to remove the oil pressure
relief valve piston and spring. Refer to the
following inspection and reassembly procedures.
If the relief valve is a one-piece style, staked to
the oil pump housing (See Figures 10-15 and

internal servicing possible. If a problem with the
relief valve is encountered, the oil pump should be
replaced.
