CAUTION:

After timing belt is removed, never turn camshaft and
crankshaft independently more than such an extent as
shown in figure. If turned, interference may occur among
piston and valves, and parts related to piston and valves
may be damaged.

Never bend timing belt.
INSPECTION

Inspect timing belt for wear or crack.
Replace it as necessary.

Inspect tensioner for smooth rotation.
INSTALLATION
1) Install tensioner plate to tensioner.
Insert lug (1) of tensioner plate into hole (2) in tensioner.

4. Damper
6A1-22 ENGINE MECHANICAL (G13B, 1-CAM 16-VALVES ENGINE)
2) Install tensioner (2) and tensioner plate (3):
Do not tighten tensioner bolt (1) with wrench yet. Hand tighten
only at this time.
Check to ensure that plate movement in arrow direction as
shown in figure causes tensioner to move in the same direction.
If no associated movement between plate and tensioner occurs,
remove tensioner and plate again and reinsert plate lug into ten-
sioner hole.
3) Check that timing mark (2) on camshaft timing belt pulley is
aligned with “V” mark (1) on cylinder head cover. If not, align two
marks by turning camshaft but be careful not to turn it more than
its allowable turning range which is described on previous page.
4) Check that timing mark (2) on crankshaft timing belt pulley is
aligned with arrow mark (1) on oil pump case. If not, align two
marks by turning crankshaft but be careful not to turn it more
than its allowable turning range which is described on previous
page.
5) Install timing belt and tensioner spring (2).
With two sets of marks aligned and tensioner plate pushed up,
install timing belt on two pulleys in such a way that drive side (1)
of belt is free from any slack.
And then install tensioner spring as shown in figure, and hand-
tighten tensioner stud (3).
NOTE:

When installing timing belt, match arrow mark (
) on
timing belt with rotating direction of crankshaft.

In this state, No. 4 piston is at top dead center of compres-
sion stroke.
