support bracket then manoeuvre the starter
motor upwards and out of position.
Refitting
24 Refitting is a reversal of removal, tightening
the retaining bolts to the specified torque.
Ensure all wiring is correctly routed and its
retaining nuts are securely tightened.
If the starter motor is thought to be suspect,
it should be removed from the vehicle and
taken to an auto-electrician for testing. Most
auto-electricians will be able to supply and fit
brushes at a reasonable cost. However, check
on the cost of repairs before proceeding as it
may prove more economical to obtain a new
or exchange motor.
The switch is integral with the steering
column lock, and removal and refitting is
described in Chapter 1
