TIMING BELT “B” INSTALLATION

(1) Align timing marks on the crankshaft sprocket “B” and

counterbalance  shaft sprocket with the marks on the front
case respectively.

(2) Install the timing belt “B” on the crankshaft sprocket “B”

and counterbalance shaft sprocket. There should be no
slack on the tension side.

(3) Make sure that the relationship between the tensioner

pulley center and the bolt center is as shown in the
illustration.

(4) Move the tensioner “B” in the direction of arrow while

lifting with a finger to give a sufficient tension to the tension
side of timing belt. In this condition, tighten bolt to secure
tensioner  “B”. When the bolt is tightened, use care to
prevent shaft from turning together. If shaft is turned
together, belt will be overtensioned.

(5) Check to ensure that timing marks on sprockets and front

case are in alignment.

(6) Press with index finger the center of span on the tension

side of timing belt “B”. The bolt must deflect 5 – 7 mm.

OIL 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.

AUTO 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.

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 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.
