Electric Starters
Some engines in this series use inertia drive starting
motors while others use solenoid shift type. The inertia
drive types are covered fi rst 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 suffi cient 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 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 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.

1. Clean corroded connections and tighten loose connections.
2. Replace wires in poor condition and with frayed or broken
insulation.
1. Bypass the switch or solenoid with a jumper wire. If starter cranks
normally, replace the faulty components.
1. Check the specifi c gravity of battery. If low, recharge or replace
battery as necessary.
2. Battery too small, must be at least 250 cold-cranking amps.
1. Check for excessively dirty or worn brushes and commutator.
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
prevent resistance which could keep the engine from starting.
2. Check for seized engine components such as the bearings,
connecting rod, and piston.
