a.

Loosen mounting bolts in reverse order as shown in the figure,
and remove them.

11. If front oil seal needs to be replaced, lift it with a suitable tool, and remove it. 

CAUTION:

Be careful not to damage front cover.

12. Remove timing chain and camshaft sprockets with the following procedure:

a.

Push in chain tensioner plunger. Insert a stopper pin (A) into
hole on chain tensioner body to secure chain tensioner plunger
and remove chain tensioner 

.

NOTE:
Use approx. 0.5 mm (0.02 in) dia. hard metal pin as a stopper
pin.

b.

Secure hexagonal part of camshaft with a wrench. Loosen cam-
shaft sprocket mounting bolts and remove timing chain and
camshaft sprockets.

CAUTION:

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

13. Remove timing chain slack guide, timing chain tension guide and oil pump drive spacer.

14. Remove balancer unit timing chain tensioner with the following procedure:

: Dowel pin

: Dowel pin hole

TIMING CHAIN

a.

Press stopper tab 

 in the direction shown in the figure to push

the timing chain slack guide 

 toward timing chain tensioner (for

oil pump) 

.

• The slack guide is released by pressing the stopper tab. As

the result, the slack guide can be moved.

b.

Insert a stopper pin 

 into tensioner body hole 

 to secure the

timing chain slack guide.
NOTE:
Use a hard metal pin with the diameter of approximately 1.2 mm
(0.047 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 slack guide.

15. Remove balancer unit timing chain and crankshaft sprocket.

16. Loosen mounting bolts in reverse order as shown in the figure,

and remove balancer unit.

CAUTION:

Never disassemble balancer unit.
NOTE:
Use TORX socket (size E14).

INSTALLATION

CAUTION:

Do not reuse O-rings.

The figure shows the relationship between the mating mark on each
timing chain and that on the corresponding sprocket, with the com-
ponents installed.

1.

Check that crankshaft key points straight up.

2.

Tighten mounting bolts in numerical order as shown in figure
with the following procedure, and install balancer unit.

CAUTION:

If mounting bolts are re-used, check their outer diameter
before installation. Refer to 

EM-219, "Inspection"

.

a.

Apply new engine oil to threads and seat surfaces of mounting
bolts.

b.

Tighten No. 1 to 5 bolts.

c.

Tighten No. 6 bolt.

d.

Turn No. 1 to 5 bolts 120 degrees clockwise (angle tightening).

CAUTION:

Use the angle wrench [SST: KV10112100] (A) to check tight-
ening angle. Never make judgment by visual inspection.

e.

Turn No. 6 bolt 90 degrees clockwise (angle tightening).

f.

Completely loosen all bolts.

.

3.

Install crankshaft sprocket 

 and balancer unit timing chain 

.

• Check that crankshaft sprocket is positioned with mating

marks 

 on cylinder block and crankshaft sprocket meeting 

at the top.

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

ancer unit timing chain. 

4.

Install balancer unit timing chain tensioner.
• Be careful not to let mating marks of each sprocket and timing chain slip.
• After installation, check the mating marks have not slipped, then remove stopper pin and release ten-

sioner sleeve.

5.

Install timing chain and related parts.
• Install by aligning mating marks on each sprocket and timing

chain.

• Before and after installing chain tensioner, check again to check that mating marks have not slipped.
• After installing chain tensioner, remove stopper pin, and check that tensioner moves freely.

CAUTION:

• For the following note, after the mating marks are aligned, keep them aligned by holding them

with a hand. 

• To avoid skipped teeth, never rotate crankshaft and camshaft until front cover is installed.
NOTE:
Before installing chain tensioner, it is possible to change the position of mating mark on timing chain for
that on each sprocket for alignment.
