1. Connect the new timing chain (1) and the old timing chain (2) with the assembly link (3) (arrow).
Do not use an assembly plate and an assembly reta iner. While drawing in the new timing chain (1), the
assembly retainer can get jammed and jump off at the slide rails.
2. Slowly rotate crankshaft in direct ion of rotation of engine until the ends of the new timing chain (1) can
be connected.

Always keep new timing chain (1) meshed with the camshaft sprocket. Pull out the free end of the
timing chain (4) steadily corresponding with the drawing in of the new timing chain (1).
3. Remove the assembly link (3) and place the old timing chain (2) to the side.

4. Cover the timing case recess with a clean cloth.
Parts which have dropped into the ti ming case recess, must be removed.
5. Connect both ends of the new timing chai n (1) with the new riveted link (5).
While inserting the new riveted link (5) ensure that the center plate (6) is also installed.

cranked backwards. The
notches of the camshafts
must be pointing in the

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.
