1. Screw the overrun clutch out to the engaged position
on the pinion shaft assembly. Use a small piece of
wire with the end bent in a hook and pick the old
spring out of its channel. Slide it off the end of the
shaft. Slide the new spring over the overrun clutch
and into the spring groove. Make sure that the spring
is positioned between the shoe alignment pins and
the back flange of the anti kick-out shoes.
2. Remove the lock ring, end washer, spring retainers
and clutch return spring. Screw the overrun clutch off
the end of the pinion shaft. Remove the old spring
and install a new one. Lightly grease the pinion shaft
and reinstall the clutch, spring, retainers, end washer
and lock ring in the reverse order. Make sure the end
washer is positioned properly so that it will hold the
lock ring in its groove.
