16 Reset the primary timing chain tensioner.
NOTE
To reset the tensioner, use a suitably sized flat
blade screwdriver (1) or Tool No. J 45027 (4) to
wind the plunger in a clockwise direction, into
the tensioner shaft (2).

CAUTION
If Tool No. EN 46112 (1) is not inserted into
the tensioner body, the plunger will remain
in the locked position and no tension will be
placed on the timing chain.
18 Compress the shoe assembly into the body (2) and lock the primary timing chai n tensioner by inserting
Tool No. EN 46112 into the access hole in the side of
the body.
19 Slowly release pressure on the primary timing chain tensioner. The primary timi ng chain tensioner should
remain compressed.

20 Install a new primary timing chain tensioner gasket (1) to the tensioner (2).
21 Install the primary timing chain tensioner bolts (3)
through tensioner and gasket.
22 Ensure the primary timi ng chain tensioner mounting
surface on the engine block does not have any burrs
or defects that would affe ct the sealing of the new
gasket.
