RUNNING ADJUSTMENTS
Various adjustments are necessary from time to time in
order to keep the mechanism in
efficient running order. The periods between depend largely upon the manner in which the
car is used and no definite time can be given here for carrying out these corrections. The
car should be examined, however, every 5,000 miles (8,000 km.) and any adjustments
which appear necessary can then be made (see page 56).
ENGINE
Cylinder Head Nuts
After the first 1,000 miles or (1,500 km.) the cylinder head nuts should be checked,
with engine cold, for tightness in the order shown in Fig. 26.
Valve-Tappet Clearances
A clearance between the valve stem and the head of the tappet screw is necessary to
ensure correct closing of the valves and efficient running of the engine.
The correct running clearance is 0.015" (0.37 mm.) for both the inlet and the
exhaust valves measured with engine cold. A gauge is provided in the tool kit for
the purpose of setting these clearances.
