2. Use an ohmmeter set to the Rx1 scale. Touch the
probes between two different segments of the
commutator, and check for continuity. See Figure
8-42. Test all the segments. Continuity must exist
between all or the armature is bad.

Check
Figure 8-42. Armature Checks.
3. Check for continuity between the armature coil
segments and the commutator segments. See
Figure 8-42. There should be no continuity. If
continuity exists between any two, the armature
is bad.
4. Check the armature windings/insulation for
shorting.
Shift Fork
Check that the shift fork is complete, and the pivot and
contact areas are not excessively worn, cracked or
broken.
Brush Replacement
The brushes and springs are serviced as a set (4). Use
Brush and Spring Kit, Kohler Part No. 52 221 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 8-43.
Discard the old brush holder assembly.
Figure 8-43. 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 8-44.
Figure 8-44. Service Brush Kit.
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.)
Starter Service
Clean the drive lever and armature shaft. Apply
Kohler electric starter drive lubricant (See Section 2)
to the lever and shaft (Versilube G322L or Mobil Temp
SHC 32). Clean and check the other starter parts for
wear or damage as required.
