Electric Starting Motors
The engines in this series use solenoid shi starters. A
Delco-Remy solenoid shi starter is typically used.
Starting Motor Precautions
NOTE: Do not crank the engine continuously for
more than 10 seconds at a time. If the engine
does not start, allow a 60 second cool-down
period between starting a empts. Failure
to follow these guidelines can burn out the
starter motor.
NOTE: If the engine develops suffi cient speed to
disengage the starter but does not keep
running (a false start), the engine rotation
must be allowed to come to a complete stop
before a empting to restart the engine. If
the starter is engaged while the fl ywheel is
rotating, the starter pinion and fl ywheel ring
gear may clash, resulting in damage to the
starter.
NOTE: If the starter does not crank the engine, shut
off the starter immediately. Do not make
further a empts to start the engine until the
condition is corrected.
NOTE: Do not drop the starter or strike the starter
frame. Doing so can damage the starter.
Starter Removal and Installation
Refer to the Disassembly and Reassembly Sections for
starter removal and installation procedures.
Operation – Solenoid Shift Starter
When power is applied to the starter the electric
solenoid moves the drive pinion out onto the 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 and the start switch is released
the starter solenoid is deactivated, the drive lever
moves back, and the drive pinion moves out of mesh
with the ring gear into the retracted position.
