Starting System
. ELECTRIC STARTER
Normally the starter will require little or no service other
. than possible brush replacement. However, if through
accident or misuse, the starter requires service or
overhaul, the following will provide the information
necessary to perform this service.
Remove both battery cables from battery. Disconnect
ground cable first.
Disconnect battery cable and electrical lead wires
from starter.
Remove starter motor.
Service
When starting engine, note starter motor action. The
pinion gear should mesh quickly with flywheel ring gear
and spin engine. Once engine starts and solenoid
opens, the starter should disengage and stop. If starter
cranks engine slow, or not at all, check start circuit
components. Failure to crank is normally caused by low
battery charge, defective battery cables, corroded or
poor connections, or low temperatures. If after checking
these variables, starter continues to crank slowly, starter
must be removed and repaired.
Starter Removal
-1 Accidental starting of the engine can
result in severe personal injury or
death. Disconnect the negative battery cable andspark
plug wires while servicing engine, controls, or associated
equipment.
