If turned, interferen ce may occur between
piston and valves and valves themselves,
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) Align crankshaft sprocket key (3) with notch of cylinder block (4).
Position crankshaft sprocke t 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). Installation
CAUTION!
After timing chain is removed, never turn
crankshaft and camshafts independently
more than such an extent (“a”, “b”) as shown
in figure.
If turned, interferen
ce may occur between
piston and valves and valves themselves,
and parts related to piston and valves may be
damaged.

1) Check that match marks (1) on intake and exhaust camshaft timing sprockets are in match with notches
(2) on cylinder head as shown in figure.
2) Set key (3) and turn crankshaft to position key on upside of crankshaft.
