Adjusting method for three- and four-cylin-
der engines (Fig. 51)
– Check valve clearances with a feeler gauge.
– Valve clearances (inlet and exhaust valves)
= 0.10 mm with engine cold.

– If valve clearance is incorrect, slacken off hex
nut „1“. Turn adjusting screw „2“ until feeler
gauge „3“ can just be pulled through between
the rocker and the valve stem, with slight
resistance to its movement, after nut „1“ has
been retightened.
Important !
Repeat the procedure for all valves, noting the
adjusting method described above.
– Attach the cover to the cylinder head again;
always use new sealing rings.
– Do not use the nuts securing the cover to the
cylinder head more than twice before renewing
them.
Tightening torque: 10 Nm.
– Run the engine briefly and check that the
cover is not leaking at the cylinder head.
