3.9 CHECKING AND ADJUSTING BE ENGINE VALVE CLEARANCE
Note:
Checking and adjusting valve clearance must
only be done when the engine is cold.
1. Remove the valve cover. See "Removing
and installing".
2. Use an open-end spanner on the fan shaft to
turn the crankshaft clockwise, as seen from
the vibration damper end (this is the engine's
normal direction of rotation), until the mark
(A) is between the bolts (B) and the valves of
cylinder 1 are in overlap position.
Note:
"Overlap" is the moment at which the inlet
valves start opening and the exhaust valves
stop closing.
The inlet valves are operated by the short
rockers and the exhaust valves by the long
rockers.
