Starter Removal and Installation
Refer to the Disassembly and Reassembly sections
for starter removal and installation procedures.
Operation
When power is applied to the starter, the armature
rotates. As the armature rotates, the drive pinion
moves out on the splined drive sha and into mesh
with the fl ywheel ring gear. When the pinion reaches
the end of the drive sha , it rotates the fl ywheel
and cranks the engine. When the engine starts, the
fl ywheel rotates faster than the starter armature
and drive pinion. This moves the drive pinion out
of mesh with the ring gear and into the retracted
position. When power is removed from the starter, the
armature stops rotating and the drive pinion is held in
the retracted position by the anti-dri spring.
Starter Drive Service
Every 200 hours of operation (or annually, whichever
occurs fi rst), clean and lubricate the geartrain. If the
gears are worn, or have chipped or broken teeth, the
starter must be replaced.
It is not necessary to completely dissemble the starter
to service the geartrain. Service the starter as follows:
1. Remove the starter from the engine.
2. Remove the housing screws and the drive end
cap screw. See Figure 8-11.
Figure 8-11. Remove Housing and Drive End Cap
Screws.
3. Remove the drive end cap. The drive pinion will
either remain in the geartrain or come out with
the drive end cap. See Figure 8-12.
Figure 8-12. Remove Drive End Cap.
4. Remove the drive pinion and dust cover,
exposing the geartrain. See Figure 8-13.
Figure 8-13. Disassembled Drive Components.
5. Inspect the gears for damage or wear.
6. Clean the gears as required.
7. Apply a small amount of Kohler electric starter
drive lubricant, (see Section 2) to the geartrain.
See Figure 8-14.
