Electric Starters

Some engines in this series use inertia drive starting
motors while others use solenoid shift type. The inertia
drive types are covered first and the solenoid shift type
is covered starting on page 8.23.

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 attempts. Failure to
follow these guidelines can burn out the
starter motor.
NOTE: If the engine develops sufficient speed to
disengage the inertia drive starter but does
not keep running (a false start), the engine
rotation must be allowed to come to a
complete stop before attempting to restart the
engine. If the starter is engaged while the
flywheel is rotating, the starter pinion and
flywheel ring gear may clash, resulting in
damage to the starter.

1. Bypass the switch or solenoid with a jumper wire. If starter cranks
normally, replace the faulty components.
1. Check the specific gravity of battery. If low, recharge or replace

2. Battery too small, must be at least 250 cold-cranking amps.
1. Check for excessively dirty or worn brushes and commutator.
Brushes
Clean using a coarse cloth (not emery cloth).
2. Replace brushes if excessively or unevenly worn.
1. Make sure the clutch or transmission is disengaged or placed in
neutral. This is especially important on equipment with
hydrostatic drive. The transmission must be exactly in neutral to
or
prevent resistance which could keep the engine from starting.
Engine
2. Check for seized engine components such as the bearings,
connecting rod, and piston.
Electrical System and Components
NOTE: If the starter does not crank the engine, shut
off the starter immediately. Do not make
further attempts 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.
