The body of a
with a cover
is held together by two long bolts, usually with slot heads.
A motor without a cover band usually has four short bolts at each end but sometimes the
end is secured by a circular, toothed spring clip on the shaft, with perhaps two other bolts.
The spring clip is not reusable, so make sure you have a replacement: not all dealers stock them.
Wash all the parts in methylated spirit. Alternatively, wash them in petrol, but make sure they are thoroughly dry before reassembling the motor. A
can ignite petrol vapour and cause an explosion.
If testing the starter circuit (See Checking the starter circuit) indicates a fault in the starter motor, disconnect the battery and remove the motor from the car - complete with its attached solenoid if it is a pre-engaged type of motor.
