Camshaft Timing / Locking
Alignment of camshaft timing marks
• The mark on the camshaft sprocket (located
behind the sprocket teeth ) must align with
the marking on the casting "3Z" (left) for 3
cylinder engines or "4Z" (right) for 4 cylin-
der unit injection (Pumpe Düse) engines.
Lock the camshaft in this position by inser-
ting the Locking Pin 2588-3 through the
elongated slot on the left-hand side of the
camshaft sprocket. Having located the
locking tools in position, the belt tension can
be released and the old timing belt can be
removed.
• The 3 bolts of the sprocket can be slacke-
ned allowing the sprocket to move.
Timing Belt Tensioning
CAUTION:
Up to 2002, vehicles with unit injec-
tion (Pumpe Düse) diesel engines
have been equipped with a hydraulic
belt tensioner. Since 2002 most of
the unit injection (Pumpe Düse) engines
have changed to a mechanical tensioner.
Tensioner Tools for Hydraulic Belt
Tensioner – 2588-2, 2588-9 and 2587-1
CAUTION :
Belt tension adjustment must only be
carried out when the engine is cold.
