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
B.
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 ○

(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
pulley and its conforming mark
aligned.

(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
