DISASSEMBLY OF THE
SD-260 STARTER MOTOR
If the motor does not perform to specifications, it may
need to be disassembled for further testing of the com
ponents. Normally the starter motor should be disas
sembled only so far as is necessary to make repair or
replacement of parts. As a precaution, it is suggested
that safety glasses be worn When disassembling of
assembling the starter motor.
Before disassembly, perform the electrical tests oh
