ETIMING BELT “B” REMOVAL
Make a mark on the back of the timing belt indicating the
direction of rotation so it may be reassembled in the same
direction if it is to be reused.
NOTE
(1) Water or oil on the belt shortens its life drastically, so
the removed timing belt, sprocket, and tensioner must
be free from oil and water. These parts should not be
washed. Replace parts if seriously contaminated.
(2) If there is oil or water on each part check front case
oil seals, camshaft oil seal and water pump for leaks.
FCOUNTERBALANCE SHAFT SPROCKET
REMOVAL
(1) Set the special tool as shown to prevent the
counterbalance shaft sprocket from turning together.
(2) Loosen the bolt and remove the sprocket.
GCRANKSHAFT SPROCKET “B” REMOVAL
If it is difficult to remove the sprocket, use the special tool.
HCAMSHAFT SPROCKET BOLT LOOSENING
Use a wrench to hold the hexagonal part of the camshaft,
and then remove the camshaft sprocket mounting bolt.
INSTALLATION SERVICE POINTS
ACAMSHAFT SPROCKET BOLT TIGHTENING
Using a wrench, hold the camshaft at its hexagon and tighten
the bolt to the specification.

IOIL PUMP SPROCKET INSTALLATION
(1) Insert a Phillips screwdriver (shank diameter 8 mm shaft)
through the plug hole on the left side of the cylinder
block to block the left counterbalance shaft.
(2) Install the oil pump sprocket.
(3) Apply a proper amount of engine oil to the bearing surfaces
of the nuts.
(4) Tighten the nuts to the specified torque.
JAUTO TENSIONER INSTALLATION
(1) If the auto tensioner rod is in its fully extended position,
reset it as follows.
(2) Clamp the auto-tensioner in the vise with soft jaws.
(3) Push in the rod little by little with the vise until the set
hole A in the rod is aligned with the hole B in the cylinder.
(4) Insert a wire (1.4 mm in diameter) into the set holes.
(5) Unclamp the auto tensioner from the vise.
(6) Install the auto tensioner to front case and tighten to
the specified torque.
Caution
Leave the wire installed in the auto tensioner.
KTENSIONER PULLEY INSTALLATION
Install the tensioner pulley in such direction that its two small
holes are arranged vertically.

LTIMING 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 oil pump sprocket with its mating
mark.
(5) Remove the plug on cylinder block and insert a Phillips
screwdriver (shank diameter 8 mm) through the hole
(Engine with counterbalance shafts).
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. Keep the
screwdriver inserted until installation of timing belt is
finished.

(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.

INSTALLATION SERVICE POINTS
AINJECTORS INSTALLATION
(1) Before installing an injector, the rubber O-ring must be
lubricated with a drop of clean engine oil to aid in
installation.
(2) Install injector top end. Be careful not to damage O-ring
during installation.
BFUEL PRESSURE REGULATOR INSTALLATION
(1) Apply a small amount of new engine oil to the O-ring.
Insert the fuel pressure regulator into the delivery pipe
being careful not to damage the O-ring.
Caution
Be sure not to let engine oil get into the delivery
pipe.
(2) Check that the fuel pressure regulator turns smoothly.
If it does not turn smoothly, the O-ring may be trapped.
Remove the fuel pressure regulator and check the O-ring
for damage, and then re-insert it into the delivery pipe
and check once again.
