- Pinion/Clutch Check
1 Check clutch
Check pinion to see that it locks properly
when turned in "drive" direction and rotates
smoothly when turned in reverse
SEL569B
Pinion does not lock in either direction or
unusual resistance
is evident Replace
Replace pinion if teeth are worn or dam-
aged (Also check condition
of ring gear
teeth )
Replace clutch gear if teeth are worn or
damaged (Also check condition
of arma-
ture shaft gear teeth
)
2 Inspect pinion teeth.
3 Inspect clutch gear teeth

Rear cover metal
Gear case metal
Frictional surface of pinion
Plunger of magnetic switch
Moving portion of shift lever
With pinion driven out by magnetic switch, push
pinion back to remove slack and measure dif-
ference
