Procedure
–
Rotate crankshaft until the valves of cylinder 4 overlap
(inlet valve opens and exhaust valve closes).
–
At cylinder 1, slacken the lock nuts for the adjusting
bolts of the rocker arms.
–
Then, turn back the adjusting bolts in the rocker arms
until play can be felt between rocker arm and valve.
–
Turn adjusting bolts of both rocker arms slightly
against the valves until valve gear has no play. Check
the gradual reduction of the play through swinging
movements of the adjusting rocker arm. The point with
no play which has appeared determines the exact
contact location.
–
From this point, turn adjusting bolts in a further two
turns. Screw in lock nut and then tighten fully to 13
Nm.
