CHECK/TOP UP POWER STEERING RESERVOIR
WARNING: DO NOT start engine if fluid
level in reservoir has dropped below
dipstick - severe damage to the power
steering system could result.
NOTE: Check fluid level with engine
switched off and system cold. Ensure that
steering wheel is not turned after stopping
engine.
1.Clean and remove reservoir cap.
2.Wipe distick clean and fully refit cap.
3.Remove cap and check fluid level. Ensure fluid
level is between UPPER mark and end of
dipstick.
4.Top up, if necessary, with recommended fluid.
See LUBRICANTS, FLUIDS AND
CAPACITIES, Information, Recommended
lubricants and fluids
DO NOT fill above
UPPER mark on dipstick.CHECK/TOP UP CLUTCH FLUID RESERVOIR
WARNING: Clutch fluid will damage
painted surfaces; clean up any spillage
immediately and rinse with plenty of water.
If clutch fluid should come into contact with the
skin or eyes, rinse immediately with plenty of
water.
1.Clean and remove reservoir cap.
2.Check fluid level and top up if necessary,
maintaining the level approximately 10 mm (0.39
in) below top of reservoir, using recommended
fluid.

OF BALL JOINTS AND DUST COVERSBall joints are lubricated for life during manufacture
and require no further lubrication unless the rubber
boot has been dislodged or damaged. All joints should
be checked at specified service intervals, but more
frequently if vehicle is used under arduous conditions.
1.Check for wear in joints by moving ball joint up
and down vigorously. If free movement is
apparent, fit a new joint assembly.

DRAIN AND CLEAN FUEL SEDIMENTER, IF
FITTED
The fuel sedimenter is located on a chassis side
member on the RH side of vehicle near rear wheel. It
increases the working life of the fuel filter by removing
larger droplets of water and other matter from fuel.
NOTE: On 110/130 models with a twin tank
fuel system, two sedimenters may be
fitted, one on each side of the vehicle
chassis.
1.Slacken drain plug and allow any water to drain
off.

REPAIR
NOTE: If the camshaft gear is to be
removed during these operations its
retaining bolt should be slackened before
the timing belt is removed.
7.Slacken belt tensioner bolt.
8.Remove idler pulley.
9.Remove timing belt.
NOTE: If excessive timing belt debris is
evident in the front cover, this is probably
due to the misalignment of the front timing
cover caused by incorrect assembly of the fuel
injection pump bracket.
See FUEL SYSTEM,
Repair, Fuel Injection pump
NOTE: During use, a belt develops a wear
pattern relative to its running direction, if
the original belt is to be re-used it must be
refitted so that it rotates in the original direction.
Mark belt direction of rotation, using soft chalk, to
ensure correct refitment.
CAUTION: The belt must be stored on its
edge on a clean surface and in such a
manner that bends are not less than 50
mm (2.0in.) radius. Do not bend belts at an acute
angle, otherwise premature failure could result.Belt tensioner
NOTE: The belt tensioner need only be
removed if it is being replaced or for
access purposes to remove front cover.

Timing belt fitting and tensioning
NOTE: It is important that belt tensioning
is carried out carefully and accurately. The
following procedure involves tensioning
the belt twice to ensure that it is equally tensioned
between each gear. New and original belts are
tensioned to different figures.
