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.

Figure 10-14. Governor Shaft Press Depth.

Figure 10-15. Removing Oil Pump.

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.
