Adjust and check condition of the fan belt
The fan belt should be sufficiently tight to drive the alternator and
water pump without loading the bearings unduly. The adjustment is
correct when the belt can be moved laterally 13 mm (½ in) at the mid
point between the alternator and water pump pulleys. (figure 9) If
adjustment is necessary proceed as follows:
1. Slacken the alternator front mounting bolt.
2. Slacken the adjustment locking screw at the front of the
alternator allowing it to be moved on the slotted strap.
3. Pivot the alternator away from the engine until the correct
slack is achieved. Maintain the alternator in this position and tighten
the locking screw and front mounting bolt. Re-check the adjustment.
Note: The front lower mounting must be slackened completely before
making any adjustment as any strain on the lower fixings could distort
or damage the mountings.
Regularly examine the fan belt for wear and renew if necessary.

Check security of starter and alternator fixing bolts
Starter Motor
Using a torque wrench set to 4.15 to 4.84kg/m (30 to 35
lb/ft) check tightness of attachment nuts and bolts.
Alternator
1. Check tightness of front mounting bolt - 2.1 to 2,7 kg/m (15
to 20 lb/ft).
2. Check alternator to strap locking screw - 1.1 to 1,3 kg/m (8
to 18 lb/ft).
Check security of engine mountings
The engine and gearbox assembly is secured to the frame at three
points.
1. Check tightness of front right and left hand attachment nuts
- 2.76 to 3.46 kg/m (20 to 25 lb/ft).
2. Check tightness of gearbox rear attachment nuts - 2.07 to
2.49 kg/m (15 to 18 lb/ft).
Check/adjust carburettor settings
Start the engine and warm to normal running temperature. Push the
choke control fully home.
1. Ensure the fast idling screw is clear of the choke cam.
2. Adjust idling screw to achieve an idling speed of
approximately 800 to 850 rpm. Should these adjustments fail to
achieve satisfactory results refer to Section P.
Lubricate accelerator linkage
Using an oil can, lubricate the accelerator linkages on the carburettor.
Wipe away surplus oil (figure 5)
Routine maintenance - under body
Check and top-up gearbox oil
1. Place the vehicle on ramp or over pit.
2. Remove gearbox level plug and observe oil level correct
when in line with the bottom of the level hole threads (figure 10).
3. If necessary top up via the level hole using a pump type oil
can with a flexible nozzle charged with the recommended oil until the
level is correct.
