Precautions: In the event of a
"
false start
"
(engine gets up sufficient speed to disengage starter but
fails to continue running), the engine must be com
p
letel
y
stopped before another starting attempt is
made
--
if the flywheel is still rotating, the drive
ini ion
and ring gear will clash and almost certainl
y
be damaged.
Also
llmit
cranking (continuous)
to
a
period of 10 seconds to prevent overheating
of
the starter.
If
cranked for
10
seconds, starter should
not
be operated
again
for
60
seconds to allow time for suffi
cient coollng.
Service:
Most starters are pre
-
lubricated during assembly and do not require further lubrication until
disassembled for overhaul or other reasons. Some earlier model starters on the
K662
have hinged
oiler cups
-
-
these should be lubricated every 300 hours with
8
-
10 drops of medium grade engine oil.
The condition of brushes and commutator should be checked occasionally.
Replace brushes that
are unevenly worn or if excessively worn.
Brushes must slide freely in holders. Replace springs if
discolored (blue) from overheating.
If
commutator is dirty, clean with coarse cloth. If extremely
dirty, polish with
#OO sandpaper or commutator stone
-
-
do not use emery cloth.
If commutator
is
grooved or mica insulation is high, the armature shouldbemoved for reconditioning.

Trouble Analysis:
If
starter fails to energize,
first check wiring, starting switch or solenoid and
con-
F~tion of battery. Clean
or
replace badly corroded or dirty contacts
--
replace wires if frayed or
cracked.
Bypass start switch or solenoid with
jumper wire
-
-
if starter cranks normally, replace defec
tive switch or solenoid.
If starter turns too slowly and battery
is
in good condition, check for dirty
brushes or commutator and
s-rvice if needed.
If starter turns too slowly after brushes and commutator are checked, remove starter from
engine and check armature for binding. Armature should turn freely
--
if not, the cause could be too
little end play or improperly lubricated or badly worn sleeve bearings.
If starter spins without engaging (applies to Bendix type only),
the cause may be
a
dirty or
improperly lubricated Bendix
assembly. Do not dip drive in cleaning solution as this could damage
clutch. Brush solution on spline, wipe dry then apply dry spray type lubricant. Replace Bendix
assembly if pinion or splined sleeve is damaged.
If the
K482
type Bendix is moved into the extended
or engaged position while being cleaned, it will lock in this position
-
-
do not try to force it back into
the retracted position.
K482
starter can he installed on engine with pinion in engaged or disengaged
position.
