7.8.8 Checking the valve lash
• Test the valve lash (60/1) on a cold engine by
placing a feeler gauge between the upper part of
the tappet (60/3) and the rocker arm (60/2).
If necessary, adjust the valve lash as follows:
• Slacken counternut (60/4).
• Using a screwdriver, adjust the setting screw
(60/5) in such a way that the correct valve lash
(60/1) is obtained after the lock nut is tightened.
• Re-tighten counternut.
Valve adjustment
• Remove the cylinder head cover.
• Turn the crankshaft in normal direction of rotation
until the inlet valve 61/7 of cylinder no.4 begins to
open; the outlet valve 61/8 of the same cylinder is
not yet closed completely.
• Check the valve lash of valves 61/1 and 61/2 of
cylinder no. 1 and adjust if required.
• Adjust the valves 61/3 and 61/4 of cylinder no. 2,
as described above for the valves of cylinder no. 4,
for overlap.
• Then check the valve lash of valves 61/5 and 61/6
of cylinder no. 3 and adjust if required.
• Adjust the valves 61/1 and 61/2 of cylinder no. 1
for overlap.
• Check the valve lash of valves 61/7 and 61/8 of
