5. Perform Steps 10-13 in the “Starter Reassembly”
sequence. Installation must be done after the
armature, drive lever, and frame are installed, if
the starter has been disassembled.
Brush Replacement
The brushes and springs are serviced as a set (4). Use
Brush and Spring Kit, Kohler Part No. 25 221 01-S, if
replacement is necessary.
1. Perform steps 1-5 in “Starter Disassembly.”
2. Remove the two screws securing the brush holder
assembly to the end cap (plate). Note the
orientation for reassembly later. See Figure 8-59.
Discard the old brush holder assembly.
Figure 8-59. Removing Brush Holder.
3. Clean the component parts as required.
4. The new brushes and springs come preassembled
in a brush holder with a protective sleeve that
will also serve as an installation tool. See Figure
8-60.
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.
