Mercedes-Benz ML320. Service 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.
