9.612.0.006.7160 - 05/04

Oil and install valves and springs in cylinder head.
With the special device MWM nr. 9.407.0.690.044.6,
compress the springs and assembly the valves locks.

Install a dial indicator gauge in the special
measurement device MWM nr. 9.407.0.690.031.6 and
reset on the flat surface of the cylinder head.

Measure the height difference between valves and
cylinder head surfaces.

Install valves seals on the guides with the special
tool MWM nr. 9.610.0.690.015.4.
