– Remove locking pins -T40060- from both camshafts.
If the locking pins cannot be inserted in the camshafts, the
camshafts can be turned slightly using adapter -T40061-. To
do so, screw securing bolts for camshaft sprocket into cam-
shaft.
– Install timing chain (left-side) with camshaft sprocket and
chain tensioner.
• The elongated holes in the sprocket must be aligned cen-
trally over the tapped holes in the camshaft.
– Tighten bolts -1- for chain tensioner.
– Screw in two bolts -2- for sprocket, but do not tighten
bolts.
• It should just be possible to turn the sprocket on the cam-
shaft without axial movement.
– Lock camshaft (left-side) with locking pin -T40060-.
• The side pin -arrow- on the locking pin -T40060- must be
in line with the imaginary line between the locking pin and
the centre of the camshaft.
– Pull drill bit -3- from locating hole, this releases the chain
tensioner (left-side).
– Install timing chain (right-side) with camshaft sprocket and
chain tensioner.
• The elongated holes in the sprocket must be aligned cen-
trally over the tapped holes in the camshaft.
– Tighten bolts -1- for chain tensioner.
– Screw in two bolts -2- for sprocket, but do not tighten
bolts.
• It should just be possible to turn the sprocket on the cam-
shaft without axial movement.
Caution!
The crankshaft must not be at “TDC” at any cylinder when
the camshafts are turned. Otherwise, there is a risk of dam-
age to valves and piston crowns.
