8) Lock crankshaft inserting flat end rod or the like (2) between fly-
wheel ring gear and transmission case, after removing clutch
housing (torque converter housing for A / T) lower plate.
With crankshaft locked, remove crankshaft timing belt pulley
bolt (3).
9) Remove crankshaft pulley bolts (1).
10) Remove crankshaft pulley (4).
11) Install crankshaft timing belt pulley bolt temporarily to turn
crankshaft.
12) Release harness clamps.
13) Remove timing belt outside cover.
14) For installation of timing belt, align 4 timing marks as shown in
figure by turning crankshaft.
15) Remove timing belt tensioner (3), tensioner plate (2), tensioner
spring (5) and timing belt (1).

1. Camshaft allowable turning range - - - By timing mark,
within 90 from “V” mark on head cover on both right
and left.
2. Crankshaft allowable turning range - - - By punch mark,
within 90 from arrow mark on oil pump case on both
right and left.

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.

6) To take up slack of timing belt, turn crankshaft two rotations
clockwise after installing it. After making sure that belt is free
from slack, tighten tensioner stud first and then tensioner bolt
to each specified torque.
Then confirm again that two sets of marks are aligned respec-
tively.
