Glow Plugs
The glow plugs heat the prechambers in the cylinder head.
This helps the engine start easier in cold weather. The glow
plugs can be tested with an ohmmeter. Each glow plug
should have a resistance of 0.7 to 1.0 ohms. Replace glow
plugs with a resistance that is out of this range.

Starter
The major components of the starter are the starter motor,
the starter solenoid, and the pinion assembly. The starter
motor turns the pinion assembly through an idler gear.
When the starter solenoid is energized, it energizes the
starter motor through a set of heavy duty contacts, and it
extends the pinion gear to engage the ring gear on the
engine’s flywheel. The pinion assembly includes an over-
running clutch that allows the pinion gear to turn freely if
the engine is turning faster than the starter while the starter
is energized.

Disassembly
1. Disconnect the stator lead from the C terminal on the
side of the starter solenoid.
2. Remove the two through bolts from the commutator
cover and remove the starter motor from the starter
solenoid and pinion housing.
3. Disassemble the starter motor.
Starter Motor
a. Remove the two screws, which fasten the brush
ring to the commutator, from the back of the com-
mutator cover and remove the commutator cover
from the starter motor.
