Horn
The high-tone horn is secured to the front RH of the engine
compartment by two ¼$ UNF set screws, washers and nuts. If
defective the horn must be renewed.
Windscreen wiper and motor
The windscreen wiper motor is a single-speed type with a self-
parking switch. It drives two wheel boxes, located on the front
scuttle panel, via a flexible cable rack running in rigid tubes.
Routine maintenance
Keep the wiper blades in good condition to ensure efficient
wiping. The windscreen should be kept clean to prevent possible
scratching of the surface due to deposits of grit, tar etc. These
deposits should be removed from the windscreen with
methylated spirit. On no account should the windscreen ever be
cleaned with wax or a silicone based cleaner.
Erratic operation or complete failure may be caused by a
mechanical or electrical defect, the symptoms and rectification
being detailed below.
a) Mechanical
A kinked or damaged cable rack "bundy" tube will prevent the
rack from moving freely, thus overloading the motor and
restricting the wiper operation. The tubing must be reformed or
renewed. On no account bend the bundy tubing to a radius of less
than 9" (228mm). Check that the wheel boxes are not seized or
have excessive clearance. A worn or seized wheel box must be
renewed. Ensure that the rack is copiously lubricated with general
purpose grease.
b) Electrical
Check that the electrical plug in the wiper motor is clean and
secure. A delay in operation or complete failure can be caused by
a faulty fascia switch. This can be tested by substitution.
If all other mechanical and electrical components have been found
to operate correctly then it is possible that the motor has failed
and a replacement unit should be fitted.
To remove wiper motor (Figure 10)
1. Prise the wiper blades from their wheel box splined
spindles.
2. Disconnect the wiring plug from the wiper motor.
3. Disconnect the cable rack tubing from the motor at the
union fitting.
4. Remove two ¼" UNF set screws, plain and lock washers
and nuts and remove the "U" clamp securing the wiper
motor to the body.
5.
Remove the motor, pulling the rack from the tubing as
you do so.
6.
Refit in reverse order.
Wheel boxes and rack tubing
To remove
1. Remove the fascia (see Section R).
2. Unscrew four self-tapping screws and remove the wheel
box cover plates.
3. Detach the wiper arms and remove the wheel box
retaining nuts, washers and waterproof spacers.
4. Disconnect the cable rack tubing at the union fitting on
the wiper motor.
5. Push the wheel boxes through their fixing holes into the
cabin.
6. From within the vehicle, disconnect the intermediate
bundy tube from the RH wheel box which can then be
withdrawn, complete with the overrun tube still fitted.
7.
Disconnect the wiper motor to wheel box tube from the
LH wheel box which can now be withdrawn, complete
with the intermediate tube still attached.
8. From under the bonnet, the wiper motor to wheel box
tube can now be removed.
To replace
1. Insert the wiper motor to wheel box tube through the
grommet in the bulkhead and locate in position.
2. From inside the vehicle fit the LH wheel box, complete
with intermediate tube.
3. Locate the RH wheel box, complete with overrun tube
and connect to the intermediate tube.
4. Reconnect the tubing at the wiper motor union fitting.
5. Position both wheel boxes through their holes in the
front scuttle panel.
6. Secure the wheel boxes to the front scuttle panel with
the waterproof spacers, washers and nuts. Refit the
wiper arms.
7. Replace the wheel box cover plates, securing with four
self-tapping screws.
8. Replace the fascia (see Section R).
Specification
Type:
Light running current
Light running speed
Lighting
The headlamps are of the "sealed beam" type incorporating the
pilot lamps. The filament in the light unit being sealed between
the lens and reflector. In the event of main or dipped beam failure
the light unit must be replaced
The pilot lamp is of the "capless" type and can be replaced in the
event of failure.
Maximum efficiency is obtained and discomfort to other road
users avoided if the headlamps are correctly focused, ensuring
that the beam is not projected above the horizontal, particularly
when the vehicle is fully laden.
