Section TDM
To replace the filter element, leave the hose attached, and release the four over-centre clips securing the
top cover of the air filter housing. Raise the cover and ensure that the filter element remains in the lower
housing before swinging the cover aside. Lift out the element and clean the inside of the filter housing and
cover, including the joint line recess.
Fit the new element into position in the lower housing, and refit the top cover, ensuring that the filter seal
is correctly located in the cover recess. Engage each of the four over-centre fasteners, and snap each clip
closed.
Alternator Belt
A single multi-rib type belt is used to transmit drive from the crankshaft to the alternator. The belt requires
no periodic maintenance other than a visual check of its condition. If the belt exhibits any evidence of physical
damage, cracking, fraying, perishing, abrasion or contamination, it should be replaced. Note that some super-
ficial cracking of the belt rib rubber covering is normal and need not cause concern, but isolated deeper cracks,
affecting the underlying belt structure, require the belt to be replaced. In the case of oil contamination, the
cause must be identified and rectified, and each of the pulleys must be thoroughly degreased before the new
belt is fitted.
To replace the belt:
Slacken the alternator pivot bolt (A).
Slacken the clamping bolt (B) securing
the alternator to the slotted strap.
Turn the adjuster bolt (C) in the end of
the slotted strap to allow the alternator
to be swung towards the engine, and
unhook the belt from the pulleys.
Fit the new belt over the two pulleys,
ensuring it is correctly seated in the
grooves, and tension the belt such that
moderate finger pressure at the centre
of a belt run produces a one way deflec-
tion of 6 mm.
Tighten the clamping and pivot bolts.

Sparking Plugs
Renew the sparking plugs in accordance
with the Maintenance Schedule. Remove the
two screws securing the spark plug access
cover, and pull off the HT lead from each spark
plug. Use an airline or vacuum cleaner to re-
move any loose dirt from the plug wells be-
fore unscrewing the spark plugs using a 16
mm (5/8") A/F spark plug socket spanner.
Take precautions to prevent debris falling into
the open plug holes.
Check the electrode gap of each new
plug, and reset if necessary to 0.9mm (0.035
in). Fit the plugs taking care not to cross-
thread, and tighten to 25 Nm. Refit the plug
leads, pressing firmly, and checking that they
are correctly located in their routing clips.
Secure the access cover.
