filler cap. Water is removed by means of
the drain tap fitted to the side of the
coalescer sump.

coalescer lid and must be cleaned regularly
by washing in petrol or a similar spirit.
When refitting ensure filter mesh is below
exhaust port. The oil feed pipe should be
cleaned in a similar manner and blown
through with an air line.

and minimum levels marked on the dipstick.

2. Slacken the nuts that secure the vacuum
pump, move the vacuum pump to give the
required belt tension and tighten the nuts.
Check the tension again and readjust, if
necessary.
3. V Belt tension is correct when the deflection
is 4mm with a force of 1.5kg applied at the
centre of top run.
