and parts related to piston and valves may be
damaged.

1) Remove timing chain cover referring to “Timing
Chain Cover Removal and Installation”.
2) By turning crankshaft, align camshafts and
crankshaft at specific position as follows.
a) Align both intake and exhaust camshaft timing
sprocket marks (1) with notches (2) of cylinder
head respectively.
b) Position crankshaft sprocket key (3) at upside of
crankshaft as shown in figure.
3) Remove timing chain tensioner adjuster assembly
(5).4) Remove timing chain tensioner (6).
5) Remove timing chain No.1 guide (7).
6) Remove timing chain (8) with crankshaft timing
sprocket (9).

CAUTION!
• Keep working table, tools and hands clean
while overhauling.
• Use special care to handle aluminum parts
so as not to damage them.
• Do not expose removed parts to dust.
Keep them always clean.

Removal
1) Remove timing chain cover referring to “Timing
Chain Cover Removal and Installation”.
2) Remove timing chain referring to “Timing Chain and
Chain Tensioner Removal and Installation”.
3) For engine with VVT, with hexagonal section (1) of
intake camshaft (2) held stationary with spanner or
the like, loosen mounting bolt of intake cam timing
sprocket assembly (3) and remove it.
CAUTION!
Never attempt to loosen mounting bolt with
intake cam timing sprocket assembly held
stationary. Failure to follow this could result
in damage to lock pin.
Do not loosen bolt “a” because intake cam
timing sprocket assembly is not serviceable.

4) Loosen camshaft housing bolts in such order as
indicated in figure and remove them.
5) Remove camshaft housings.

Visual inspection
Check piston pin, connecting rod small end bore and
piston bore for wear or damage, paying particular
attention to condition of small end bore bush. If pin,
connecting rod small end bore or piston bore is badly
worn or damaged, replace pin, connecting rod and/or
