complete motor or having a repair undertaken
by an automobile electrician.
2 With the motor removed from the car as
described in Section 11, undo and remove the
four gearbox cover retaining screws and lift
away the cover (see illustration). Release the
circlip and flat washer securing the
connecting rod to the crankpin on the shaft
and gear. Lift away the connecting rod
followed by the second flat washer.
3 Raise the circlip and flat washer securing
the shaft and gear to the gearbox body.
4 De-burr the gearshaft and lift away the
gear, making a careful note of the location of
the dished washer.
5 Scribe a mark on the yoke assembly and
gearbox to ensure correct reassembly, and
unscrew the two yoke bolts from the motor
yoke assembly. Part the yoke assembly,
including armature, from the gearbox body.
As the yoke assembly has residual magnetism
ensure that the yoke is kept well away from
metallic dust.
6 Unscrew the two screws securing the
brushgear and the terminal and switch
assembly and remove both the assemblies.
7 Inspect the brushes for excessive wear. If
the main brushes are worn to less than the
minimum specified length, or the narrow
section of the third brush is worn to the full
width of the brush, fit a new brushgear
assembly. Ensure that the three brushes
move freely in their boxes.
8 If either the brushes or the limit switch are
to be renewed on early motor assemblies, it
will be necessary to unsolder the wires at the
switch and then re-solder the new wires. On
later types the wires are retained by Lucar
connectors which are simply detached. In all
cases make a note of the wire positions
before disconnecting.
Reassembly
9 Reassembly of the windscreen wiper motor
is the reverse sequence to dismantling.

Removal
1 Remove the windscreen wiper motor as
described in Section 11.
2 Carefully lift back the engine compartment
bulkhead insulation to provide access to the
wheelboxes.
3 Undo and remove the retaining nut and
spacer from each wheelbox (see illustration).
4 Slacken the nuts that clamp the guide
tubes between the wheelbox plates and then
lift out the guide tubes.
5 The wheelboxes can now be lifted out.
6 With the wheelboxes removed, withdraw
the wheelbox plates and lift out the spindle
and gear. Examine the gear teeth for wear and
renew as necessary.
Refitting
7 Refitting is the reverse sequence to
removal; bearing in mind the following points.
a) Lightly lubricate the spindles and gear
teeth with a general purpose grease
b) Do not tighten the nuts that clamp the
guide tubes between the wheelbox plates
until the motor and cable rack have been
refitted
c) Ensure that the bend radius on the guide
tube nearest to the motor is not less than
230.0 mm

later models
Removal
11 On later models the washer pump and
reservoir are located in the luggage
compartment. The pump is clipped into the
side of the reservoir (see illustration).
