6) Remove the belt idler (A).
7) Remove the timing belt.
CAUTION:
After the timing belt has been removed, never
rotate the intake and exhaust, camshaft sprock-
et. If the camshaft sprocket is rotated, the in-
take and exhaust valve heads strike together
and valve stems are bent.

ER ASSEMBLY AND BELT IDLER
1) Preparation for installation of automatic belt ten-
sion adjuster assembly:
NOTE:
Always use a vertical type pressing tool to move
the adjuster rod down.
Do not use a lateral type vise.
Push the adjuster rod vertically.
Be sure to slowly move the adjuster rod down ap-
plying a pressure of 294 N (30 kgf, 66 lb).
Press-in the push adjuster rod gradually taking
more than 3 minutes.
Do not allow press pressure to exceed 9,807 N
(1,000 kgf, 2,205 lb).
Press the adjuster rod as far as the end surface
of cylinder. Do not press the adjuster rod into the
cylinder. Doing so may damage the cylinder.

Do not release the press pressure until stopper
pin is completely inserted.
(1) Attach the automatic belt tension adjuster
assembly to the vertical pressing tool.
(2) Slowly move the adjuster rod down with a
pressure of 294 N (30 kgf, 66 lb) until the adjust-
er rod is aligned with the stopper pin hole in the
cylinder.
(3) With a 2 mm (0.08 in) dia. stopper pin or a 2
mm (0.08 in) (nominal) dia. hex bar wrench in-
serted into the stopper pin hole in the cylinder,
secure the adjuster rod.

(2) Align single line mark (A) on the exhaust
camshaft sprocket (RH) with notch (B) on timing
belt cover.
(3) Align single line mark (A) on the intake cam-
shaft sprocket (RH) with notch (B) on timing belt
cover.
(Make sure double lines (C) on intake camshaft
and exhaust camshaft sprockets are aligned.)
(4) Align single line mark (A) on exhaust cam-
shaft sprocket (LH) with notch (B) on timing belt
cover by turning the sprocket counterclockwise
(as viewed from front of engine).
(5) Align the single line mark (A) on intake cam-
shaft sprocket (LH) with notch (B) on timing beltcover by turning the sprocket clockwise (as
viewed from front of engine).
Ensure the double lines (C) on intake and ex-
haust camshaft sprockets are aligned.
(6) Ensure the camshaft and crankshaft sprock-
ets are positioned properly.
CAUTION:
Intake and exhaust camshafts for this DOHC
engine can be independently rotated with the
timing belts removed. As can be seen from the
figure, if the intake and exhaust valves are lifted
simultaneously, their heads will interfere with
each other, resulting in bent valves.
