Front End - Volvo 121 Servicing

Power transmission
30 Checking the free travel of the clutch yoke
In order to prevent the clutch from slipping, the free travel of the clutch
yoke must be checked regularly and adjusted if necessary after 10 000
km (6 000 miles) of operation. If the clutch does not disengage in a satis-
factory way, the free travel of the clutch pedal must be checked. See the
data on page 57.
The clutch should be checked and adjusted at a Volvo workshop since
these workshops have the necessary equipment.
31 Check the propeller shaft
Every 10 000 km (6 000 miles) the rubber seal on the spline shaft should
be checked as well as the universal joints. If the rubber seal is damaged,
should be replaced and the new seal filled with molybdenum disulphide
it
grease before fitting.
Brakes
32
Check and overhaul the brakes
After every 10 000 km (6 000 miles) running the vehicle should be taken
to a Volvo workshop for controlling the function of the brakes.
As the rear wheel brake linings become worn the brake shoes must be
adjusted in order to obtain satisfactory braking effect.
The disc brakes on the front wheels are self-adjusting.
In connection with this check the brakes should also be inspected for
wear. The filter on the servo cylinder should be replaced in connection
with the changing of the rear brake shoes.

Front end

33 Check the front wheel alignment
Correct front wheel alignment is of vital importance for the steering of
the vehicle. Faulty adjustment can also mean heavy wear on the tyres.
Have the front wheel alignment checked at a Volvo workshop at regular
intervals, for example after every 10 000 km (6 000 miles). If the vehicle
has been involved in a collision or heavy impact and it is suspected that
the front end may have been affected, take the vehicle to a workshop
for a check of the front wheel alignment as soon as possible. The front
wheel alignment angles are shown on page 58.
34 Check the ball joints, tie-rod, etc.
After every 10 000 km (6 000 miles) the vehicle should be taken to a
Volvo workshop for a check of the front end concerning excessive play
in the ball joints, steering gear, etc. Also check the ball joint seals for
damage and leakage. When new seals are fitted they should be filled with
chassis grease.
