Inspection and Reconditioning
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.
Reassembly
1. Install the locking tab thrust washer on the
governor gear shaft with the tab down.
2. Position the regulating pin within the governor
gear/flyweight assembly and slide both onto
governor shaft.
Oil Pump Assembly
Disassembly
1. Remove the two hex flange screws.
2. Remove the oil pump assembly from the oil pan.
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.

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
10-17), removal should not be attempted, nor is
internal servicing possible. If a problem with the
relief valve is encountered, the oil pump should
be replaced.
