Removal
Wiper motor
1Operate the wiper motor, then switch it off
so that it returns to its rest position.
2 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
3 Dependent on model, disconnect and
remove the air cleaner components as
necessary to allow access to remove the
bulkhead panel.
4 Remove the cooling system expansion tank
as described in Chapter 3.
5 Release the wiring loom, any connectors,
cable-ties and hoses from the right-hand half
of the bulkhead panel, then remove its rubber
seal.
6 The right-hand half of the bulkhead panel is
secured by screws and a single nut. The nut is
located behind the panel at the bonnet hinge
end. Release the right-hand half of the panel
and, having ensured that it is free to move,
remove it (see illustrations) .
7 Unscrew the nut from the driving shaft, and
pull the crank off the driving shaft taper (see
illustration) .
8 Undo the three wiper motor retaining bolts and withdraw the motor assembly
(see
illustrations) . Remove the motor cover, then
disconnect the multi-plug and remove the
motor from the vehicle.

accessible position, using the ignition switch
as a means of stopping the wiper motor
returning to the parked position.
11 Disconnect the battery negative (earth)
lead (refer to Chapter 5A, Section 1).
12 Prise the linkages off their ball pivots as
required, using a suitably-sized open-ended
spanner. The crank has a dual (vertically
stacked) ball pivot with a bellows separating
the two linkages (see illustrations) .
13 If the running faces of the ball pivots are
damaged, the pivot shaft(s) or crank must be
renewed.

sockets on the linkages, then locate them on
their appropriate ball pivots and press into position using a suitably-sized socket. The
bellows between the two linkages on the
crank must also be greased using the
specified lubricant. Refit the bulkhead panel
rubber seal on completion.
