c. Insert a wire (1.4 mm in diameter) into the set holes.
d. Unclamp the auto tensioner from the vise.
(2) Install the auto tensioner. Leave the wire installed in the
auto tensioner until the timing belt is installed.

TENSIONER PULLEY INSTALLATION
Install the tensioner pulley as shown in the illustration.

TIMING BELT INSTALLATION
(1) Place the exhaust side camshaft sprocket in a position where its timing mark is one tooth offset from the timing
mark on the rocker cover in the counterclockwise direction.
NOTE
Even if the timing marks on the sprocket and the rocker
cover are brought into alignment, the exhaust camshaft
is forced back by the valve spring tension. It is stabilized
at a position one tooth before the timing mark.
(2) Align the timing mark on the intake side camshaft sprocket with that on the rocker cover.
NOTE
Even if the timing marks on the sprocket and the cover
are brought into alignment, the intake camshaft is forced
to turn one tooth in the clockwise direction by the valve
spring tension and stabilized there.
(3) Place the timing mark on the crankshaft sprocket one tooth this side from the mated timing mark as in the case
of the camshaft sprocket.

(4) Align the timing mark on the oil pump sprocket with its
mating mark.
(5) Remove the plug on the left side of the cylinder block
and insert a Phillips screwdriver (shank diameter 8 mm)
through the hole.
If it can be inserted as deep as 60 mm or more, the
timing marks are correctly aligned. If the inserted depth
is only 20 – 25 mm, turn the oil pump sprocket one turn
and realign timing marks. Then check to ensure that the
screwdriver can be inserted 60 mm or more.
(6) Remove the Phillips screwdriver. Place the oil pump sprocket in a position where its timing mark is one tooth
offset from the mated timing mark in the counterclockwise
direction.
(7) Fit the timing belt over the exhaust side camshaft sprocket, and secure it at the illustrated position using a paper
clip.
(8) Turn the intake side camshaft sprocket as shown to a position where its timing mark is one tooth offset from
the mated timing mark in the counterclockwise direction.
Then, fit the timing belt over the sprocket and secure
it with a paper clip.
NOTE
The intake camshaft will be turned a little clockwise by
the valve spring tension and stabilized in position even
if the belt is clipped at one tooth offset position.
(9) Check to ensure that the timing marks on the intake camshaft sprocket side are in alignment when the exhaust
camshaft sprocket is turned clockwise to align the timing
marks.
NOTE
The timing belt span between the intake and exhaust
sprockets will have 17 cogs.

(10)Fit the timing belt over the idler pulley, oil pump sprocket
and crankshaft sprocket in this order.
NOTE
Be careful that the belt does not become slack.
(11) Fit the timing belt over the tensioner pulley. NOTE
When fitting the timing belt over the tensioner pulley,
turn the intake side camshaft sprocket a little
counterclockwise, as this will facilitate the work.
(12)Turn the crankshaft pulley a little in the illustrated direction to pull up the timing belt at the idler pulley side.
(13)Check to ensure that the timing marks on the crankshaft sprocket, oil pump sprocket and exhaust camshaft
sprocket are all offset one tooth from the corresponding
timing marks in the counterclockwise direction.
(14)Using the special tool, turn the tensioner pulley in the illustrated direction to strain the timing belt. Then, secure
the tensioner temporarily by tightening the retaining bolt
lightly.
NOTE
There must be no slack in the timing belt between the
intake and exhaust camshafts.
(15)Turn the crankshaft to align the timing mark with the mark for No. 1 cylinder top dead center in the compression
stroke.
(16)Set the special tool as shown and screw it in up to the position where the wire inserted in the auto-tensioner
when installing it can be moved lightly.
