Starter Service
Clean the drive lever and armature shaft. Apply
Kohler electric starter drive lubricant (see Section 2)
(Versilube G322L or Mobil Temp SHC 32) to the lever
and shaft. Clean and check the other starter parts for
wear or damage as required.
Starter Reassembly
1. Apply drive lubricant (see Section 2) to the
armature shaft splines. Install the drive pinion
onto the armature shaft.
2. Install and assemble the stop collar/retainer
assembly.
a. Install the stop collar down onto the armature
shaft with the counter bore (recess) up.
b. Install a new retainer in the larger (rear)
groove of the armature shaft. Squeeze with a
pliers to compress it in the groove.
c. Slide the stop collar up and lock it into place,
so the recess surrounds the retainer in the
groove. If necessary, rotate the pinion outward
on the armature splines against the retainer to
help seat the collar around the retainer.
Figure 8-61. Installing Stop Collar and Retainer.
NOTE: Always use a new retainer. Do not reuse old
retainers which have been removed.
3. Install the offset thrust (stop) washer so the
smaller “offset” of the washer faces the retainer/
collar. See Figure 8-62.
