10 Windscreen wiper arms -
removal and refitting
1
Removal
1 Before removing a wiper arm, turn the
windscreen wiper switch on and off, to ensure
that the arms are in their normal parked
position with the blades parallel to the bottom
of the windscreen.
2 To remove the arm, pivot the arm back and
pull the wiper arm head off the splined drive,
at the same time easing back the clip with a
screwdriver (see illustration).
Refitting
3 When refitting an arm, place it so it is in the
correct relative parked position and then
press the arm head onto the splined drive until
the retaining clip clicks into place.

Removal
1 Remove the wiper arms from the spindles

connector from the motor, and if a separate
earth wire is fitted, detach this from the wing
valance.
4 Undo the nut securing the cable rack guide
tube to the wiper motor gearbox (see
illustration).
5 Undo and remove the two motor strap
retaining screws and lift off the strap.
6 Carefully withdraw the motor assembly
pulling the cable rack from the guide tubes.
Refitting
7 To refit the motor, lightly lubricate the cable
rack with a general purpose grease.
8 Enter the cable rack into the guide tubes
and carefully push it through, ensuring that it
engages the wheelbox gear teeth.
9 Refit the motor retaining strap and the
guide tube retaining nut.
10 Reconnect the electrical leads and the
battery terminal.
11 Switch on the wipers, check the function
of the motor and then turn it off. With the

wiper arms.

Dismantling
1 Due to the limited availability of spare parts,
the only repair which can be effectively
