Mercedes-Benz ML320. Manual — part 410

camshafts

The copper plates of the

timing chain must be
aligned with the scribe
marks on the camshaft
sprockets.

Owing to the unevenly long
paths of the timing chain it
may be necessary to crank
the engine as many as 14
times till the copper plates
get aligned with the scribe
marks on the camshaft
sprockets.

On vehicles equipped

with an air pump, the
combination valve must be
unbolted before the right
locking plate is inserted.

Installation: Replace

combination valve gasket.
