Insert a stopper pin (A) into the body hole, and then fix it with the
plunger pushed in.

NOTE:
Use approximately 1.5 mm (0.059 in) diameter. hard metal pin
as a stopper pin.

c.

Remove timing chain tensioner.

13. Remove slack guide 

, tension guide 

 and timing chain 

.

CAUTION:

Never rotate each crankshaft and camshaft individually
while timing chain is removed. It causes interference
between valve and piston.

14. Remove crankshaft sprocket and balancer unit drive component with the following procedure:

TIMING CHAIN

a.

Press the balancer unit timing chain slack guide 

 toward bal-

ancer unit timing chain tensioner 

.

b.

Insert a stopper pin (A) into tensioner body slit to secure the bal-
ancer unit timing chain slack guide.
NOTE:
Use a hard metal pin with the diameter of approximately 1.5 mm
(0.059 in) as a stopper pin.

c.

Remove balancer unit timing chain tensioner.
• When the holes on lever and tensioner body cannot be

aligned, align these holes by slightly moving the balancer unit
timing chain slack guide.

d.

Hold the WAF part of balancer shaft [WAF: 19 mm (0.75 in)] 

,

and then loosen the balancer unit sprocket bolt.

CAUTION:

• Secure the balancer unit shaft with the WAF part.
• Never loosen the balancer unit sprocket bolt by tightening

the balancer unit drive chain.

e.

Remove crankshaft sprocket, balancer unit sprocket and bal-
ancer unit timing chain as a set.

CAUTION:

Do not reuse O-rings.

The figure shows the relationship between the matching mark on
each timing chain and that on the corresponding sprocket, with the
components installed.

*: There are two outer grooves in camshaft sprocket (INT). The wider one is a matching mark.

1.

Check that crankshaft key points straight up.

2.

If the tension guide (front cover side) is removed, install it to the front cover.

CAUTION:

Check the joint condition by sound or feeling.

3.

Install crankshaft sprocket 

, balancer unit sprocket 

 and bal-

ancer unit timing chain 

.

• Install it by aligning matching marks on each sprocket and bal-

ancer unit timing chain. 

• If these matching marks are not aligned, rotate the balancer

shaft slightly to correct the position.

CAUTION:

Check matching mark position of each sprocket after installing the balancer unit timing chain.

TIMING CHAIN

4.

Hold the WAF part of balancer unit shaft [WAF: 19 mm (0.75 in)]

, and then tighten the balancer shaft sprocket bolt.

CAUTION:

• Secure the balancer unit shaft with the WAF part.
• Never loosen the balancer shaft sprocket bolt by tighten-

ing the balancer unit timing chain.

5.

Install balancer unit timing chain tensioner 

.

• Fix the plunger at the most compressed position using a stop-

per pin (A), and then install it.

• Securely pull out (

) the stopper pin after installing the bal-

ancer unit timing chain tensioner.

• Check matching mark position of balancer unit timing chain

and each sprocket again.
