NOTE
Do not remove the primary timing chain lower
guide (1). The primary timing chain lower guide
is not serviced separately. If the primary timing
chain lower guide must be replaced, the oil
pump assembly (2) must be replaced.

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.
Figure 6A1 – 234
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.
Figure 6A1 – 235
23 Place the primary timing chain tensioner (2) into position and loosely install the bolts (1) to the engine
block.

Right-hand Secondary Timing Chain Components – Excluding MY06 Update
1 Install the primary timing chain components, refer to Primary Timing chain Components in this Section.
2 Using Tool No. EN46111 (1), rotate the crankshaft in a clockwise direction until the crankshaft sprocket
timing mark (2) is aligned with the indexing mark (3)
on the oil pump housing.
Figure 6A1 – 240
CAUTION
In order to install Tool No. EN 46105 onto the
camshafts, rotate the camshafts. There
should be no need to rotate the camshaft
more than 45 degrees.

the camshaft sprockets (2) and the right hand
camshaft intermediate sprocket (3) aligning the chain
in the following manner:

CAUTION
Ensure that when aligning the right-hand
secondary timing chain to the right-hand
camshaft sprockets, th at the triangular
timing marks (1) on the sprocket are used,
NOT the circular mark.
