Installation of bushing in upper

balance shaft

(1)When installing the bushing, place the

side with deburring to the direction of oil seal.

Installation of pulley in upper

balance shaft

(1) Fix pulley in the balance shaft with a

tool as shown in the illustration.

(2) Fasten the bolt to assigned torque.

Installation of timing belt B

(1) Align the marks on the crankshaft pulley

and balance shaft pulley with the marks on

the front cover respectively.

(2) Install timing belt B in the crankshaft

pulley and balance shaft pulley. There

should not be loose in the tensioner side.

(3) Make sure that the position of tensioner

center and bolt center as shown in the

illustration.

(4)

While putting power on the side of timing

belt tensioner with finger, move

tensioner B according to the arrow. Now

fasten the screw bolt to fix tensioner

Caution: When fastening the bolt, do not

keep the axle revolve with the pulley in

case that the belt gets too tight.

Fasten the crankshaft bolt

(1) Fix the flywheel with special tool.

(2) Install crankshaft bolt.

Installation of pulley in oil pump

(1) Insert cross-ended screwdriver to the left

side of hole in the cylinder to prevent

turning of balance shaft.

(2) Install pulley of oil pump.

(3) Apply oil to the combining side of screw nut

and bearing.

(4) Fasten the screw nut with a torque of 54Nm.

Installation of automatic tensioner

(1) If the automatic tensioner is in the

stretching position, it should be drawn

back according to the following steps.

(2) Fasten the automatic tensioner with

vises that have soft opening.

Caution:

·As there is a stretching screw plug at

the bottom of automatic tensioner, a

plain pad should be inserted between

the vises and the screw plug to prevent

their direct contact.

(3) Slowly push the vises in until the rod

hole and oil tank ○

gets aligned.

(4) Insert the steel wire(diameter 1.4mm) to

the aligned hole.

(5) Disassemble the automatic tensioner from

the vises.

(6) Install the automatic tensioner in

the front cover, fastening the bolt

with a torque of 24Nm.

Caution:

· Leave the steel wire in the

automatic tensioner.

Installation of tensioning pulley

(1)Install the tensioning pulley and keep

the two pin holes in a vertical line.

Installation of timing belt

(1) Make sure that the belt tensioner is

installed properly.

(2) Make the timing mark in the camshaft

pulley and that in the cylinder cover

aligned.

(3) Make the timing mark in the

crankshaft pulley and that in the

front cover aligned.

(4) Keep the timing mark in the oil pump

(5) Disassemble the plug from the cylinder

block and then insert the cross-ended

screwdriver (diameter of8mm) to the hole. If it
could be inserted more than 60mm in, it means that
the timing marks are aligned. If the range that
could not be inserted above 20～25mm, the oil
pump pulley should be turned for one revolution and
the timing marks should be then aligned. Again
check if the screwdriver could be inserted over
60mm. Keep the screwdriver in the inserting
position until the installation of belt finishes.

(6)Connect the timing belt to the crankshaft pulley,

middle pulley, camshaft pulley and tensioner
pulley in turn.

(7) Raise the pulley of the tensioner to the direction

of arrow and then fasten the central bolt.

(8) Make sure that all the timing marks are aligned.

(9) Disassemble the screwdriver inserted in step (5)

and fix the plug.

(10)Rotate counterclockwise the crankshaft for a

quarter of revolution until all the timing marks
again get aligned.

(11)Install the special tools socket wrench and

torque wrench to the tensioner pulley and then
loosen the central bolt in the pulley of
tensioner.

Remarks:

If special tools could not be applied, a general
torque wrench that could measure a torque of 0
to 0.5 KgM may be used.

(12)Fasten to the torque of 3.5N.m(0.35 KgM) with a

torque wrench.

(13)While keeping the tensioner pulley with special

tool and torque, fasten the central bolt to
standard value.

(14)Rotate clockwise the crankshaft two revolutions

and lay it for about 15minutes. Then check
whether the fixing steel wire of automatic
tensioner could slide freely.

Remarks:
If the steel wire could not slide freely,
repeatedly do the steps after (10) until the
steel wire slides.

(15)Take off the fixing steel wire of automatic
tensioner.

(16)Measure the distance “A” (between the tensioner

arm and the automatic tensioner itself).

Standard value: 3.8－4.5mm
