Electrical System and Components
Operation - Inertia Drive Starters
When power is applied to the starter, the armature
rotates. As the armature rotates, the drive pinion
moves out on the splined drive shaft and into mesh
with the fl ywheel ring gear. When the pinion reaches
the end of the drive shaft, 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-drift
spring.
Starter Drive Service
Every 500 hours of operation (or annually, whichever
occurs fi rst), clean and lubricate the splines on the
starter drive shaft. If the drive pinion is worn, or has
chipped or broken teeth, it must be replaced. See
Figure 8-16.
It is not necessary to completely disassemble the
starter to service the drive components.
Style "A" Drive Service
1. Remove the starter from the engine and remove
the dust cover.
2. Hold the drive pinion in a vice with soft jaws
when removing and installing the stop nut. The
armature will rotate with the nut until the drive
pinion stops against internal spacers.
NOTE: Do not overtighten the vise as this can
distort the drive pinion.
3. Remove the stop nut, stop gear spacers, anti-drift
spring, dust cover spacer, and drive pinion.
4. Clean the splines on drive shaft thoroughly with
solvent. Dry the splines thoroughly.
5. Apply a small amount of Kohler electric starter
drive lubricant, Part No. 52 357 01-S, to the
splines. The use of other lubricants may cause
the drive pinion to stick or bend.
6. Apply a small amount of Loctite
®
No. 271 to the
stop nut threads.
7. Install the drive pinion, dust cover spacer,
anti-drift spring, stop gear spacer, and stop
nut. Torque the stop nut to
17.0-19.2 N·m
(150-170 in. lb.) . Reinstall the dust cover.
