TIMING CHAIN
Revision: 2004 November 2004 FX35/FX45
NOTE:
To remove timing chain and related parts, start with those on left bank. The procedure for removing parts
on right bank is omitted because it is the same as that for left bank.
a. Press tab in the direction of arrow (or turn lever in the direction
of arrow) to unlock the locking with the groove that stops ten-
sioner plunger from returning.

Lightly press tensioner plunger to release the tension of
spring for this operation.
b. Push in tensioner plunger to align the hole on lever and that on
pump main body.

Pushing in tensioner too far does not allow the holes to align.
Therefore, push in plunger to the degree at which the start of
stopper groove and tab engages.
c. Insert stopper pin [hard wire with approx. 0.5 mm (0.020 in)
diameter or similar tool] to fix plunger. With plunger fixed, remove chain tensioner.
17. Remove chain tension guide and timing chain slack guide.
18. Remove timing chain and crankshaft sprocket.
CAUTION:
After removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike
the piston head.
19. With hexagonal part of camshaft locked with wrench, loosen
bolts securing camshaft sprocket to remove camshaft sprocket.
20. Perform same procedure as for left bank, remove timing chain and related parts on right side.
21. Use scraper to remove all traces of old liquid gasket from front cover and opposite mating surfaces.

Remove oil liquid gasket from bolt hole and thread.
22. Use scraper to remove all trace of liquid gasket from chain tensioner cover and intake valve timing control
covers.

INSPECTION AFTER REMOVAL
Timing Chain
Check tor cracks and any excessive wear at the roller links and link
plates. Replace timing chain as necessary.
INSTALLATION
NOTE:

The above figure shows the relationship between the mating mark on each timing chain and that on the
corresponding sprocket, with the components installed.

Parts with an identification mark (R or L) should be installed on the corresponding bank according to the
mark.
Parts with an identification mark:
–Camshaft sprocket (INT)
–Dowel pin groove of camshaft sprocket (EXH) (camshaft sprocket is same part both banks)
–Chain tension guide
–Chain slack guide

Because of parallel manufacture, there are two types of mark (link colors) for timing chain.

To install timing chain and related parts, start with those on right bank. The procedure for installing parts
on left bank is omitted because it is the same as that for installation on right bank.

1. Make sure that crankshaft key and dowel pin of each camshaft
are located as shown in the figure. (No. 1 cylinder at compres-
sion TDC)
NOTE:
Though camshaft does not stop at the position as shown in the
figure, for the placement of cam nose, it is generally accepted
camshaft is placed for the same direction of the figure.
2. Install camshaft sprockets.

Install onto correct side by checking with identification mark
on surface.

Install camshaft sprocket (EXH) by selectively using the
groove of dowel pin according to the bank. (Common part
used for both banks.)

Lock the hexagonal part of camshaft in the same procedure
as for removal, and tighten mounting bolts.
3. Install crankshaft sprockets for both banks.

Install each crankshaft sprocket so that its flange side (the
larger diameter side without teeth) faces in the direction
shown in the figure.
NOTE:
The same parts are used but facing directions are different.Camshaft dowel pin
: At cylinder head upper face side in each bank
