2) Performance Test
The starter should be submitted to
performance tests whenever it has
been overhauled, to assure its satisfac-
tory performance when installed on
the engine.
Three performance tests, no-load test,
load test, and lock test, are presented
here; however, if the load test and lock
test cannot be performed, carry out at
least the no-load test.
For these performance tests, use the
circuit shown in figure.
1) No-load test
With the switch on, adjust the variable
resistance to obtain 11 V (magnetic
switch type)

type), take the ammeter reading and
measure the starter speed. Compare
these values with the specifications.
(See specifications)
2) Load test
Apply the specified braking torque to
the starter. The condition is satisfac-
tory if the current draw and starter
speed are within specifications. (See
specifications)
3) Lock test
With the starter stalled, or not rotat-
ing, measure the torque developed
and current draw when the voltage is
adjusted to the specified voltage.

2) Inspection and Repair
Clean all disassembled parts prior to
inspection. Do not use grease-dissolv-
ing solvent for cleaning overrunning
clutch, armature, magnetic switch and
field coil.
Check all parts for excessive damage
or wear, and replace if necessary .
• Armature
a. Measure each clearance between the
armature shaft and bushing in the
housing, and between the armature
shaft and bushing in the end frame.
Replace parts if any of the clear-
ances exceeds the specified limit.
