INSPECTION Oi COMPONENTS
1.
tNSPECT TlMlNG BELT
CAUTION :
l Do not bend, twist or turn the belt inside out.
l Do not allow the belt to come into contact with oil,
water or steam.
l Do not utilize belt tension when installing or remov-
ing the set bolt of the camshaft timing pulley.
If there are defects as shotin in the figures. Check the
foljowing points and replace the timing belt if necessary.
(a) Premature parting
l Check for proper installation.
l Check the timing belt cover gasket for damage
and proper installation.
(b) If the belt teeth are crackeb or damaged, check to
see if the camshaft is locked.

c
(c) If there is noticeable wear of cracks on the belt face,
check to see if there are nicks on one side of the idler
pulley lock.
Id) If there is wear or damage on only one side of the
belt, check the
belt guide and the alignment of each
pulley.
(e) If there is noticeable wear on the belt teeth, check the
.timing
belt cover gasket for damage and check for
’ foreign materials on the pulley teeth.
2,
INSPECT IDLER PULLEY
Check the turning smoothness of the timing belt idler
pulley.
If necessary, repiace the idler pulley.
EM2909.
3” INSPECT TENSION SPRING
Check the free length of the spring.
Free length:
66 mm (2.72 in.)
If not as specified, replace the spring.

*’
(a) Install the idler pulley and tension spring.
(b) Pry the pulley toward the left as far as it will go and
temporarily tighten it.
NOTE: Remove any oil or water on the idler pulley and
keep it clean.
4. TEMPORARILY INSTALL TIMING BELT
CAUTION: The engine should be cold.
NOTE: If reusing the timing belt, install it with the rota-
tion direction mark pointing in the same direction as
before disassembly.
Install the timing belt on the crankshaft timing pulley, oil
pump drive pulley and idler pulley.

7. INSTALL CRANKSHAFT PULLEY
(a) Align the pulley’set key with the key groove of the
pulley.
(b) Install the pulley.
(c) Using SST to hold the crankshaft pulley, install and
torque the pulley bolt. .
SST MA 09213-70010 and 09330-00021
MS 092 13-54014 and 09330-00021
Torque: 2,700 kg-cm (195 ft-lb, 265 N-m) 8.
SET NO.1 CYLINDER TO TDC/COMPRESSION OF
CRANKSHAFT
Turn the crankshaft pulley and align its groove with the
“0” mark on the No.1 timing belt cover.
9. INSTALL CAMSHAFT TIMING PULLEYS
(a) Align the timing pulley matchmark with the No.2 tim-
ing belt cover matchmark.
(b) Install the timing pulley.
(c) Install the pin into the middle hole.
NOTE:
l When replacing the camshaft or the camshaft timing
pulley:
Align the center holes of the camshaft and timing
pulleys, as shown in the illustration and insert the
straight pin.
l When reusing the camshaft or camshaft timing pulleys:
Check that the straight pin hole position is in the same
position it was at disassembly, insert the straight pin.
(d) Install the pulley bolt.
(e) Using SST to hold the pulley, torque the pulley bolt.
SST 09278-54012
Torque: 500 kg-cm (36 ft-lb, 49 N-m)
(f) Check that the matchmarks on the camshaft timing
pulley are aligned with those on the No.2 timing belt
cover.

EM304
EM457
(a) Install the timing belt to the IN side and EX side.
(b) Loosen the idler pulley bolt, and torque the idler
pulley bolt.
Torque: 500 kg-cm (36 ft-lb, 49 N.m)

NOTE: Make sure that the timing belt tension at A is
equal to that at B.
If not, readjust with the idler pulley.
(c) Turn the crankshaft pulley two revolutions clockwise
from TDC to TDC.
(d) Check that the matchmark on the camshaft timing
pulley are aligned with those on the No.2 timing belt
cover.
11. CHECK TIMING BELT TENSION
(a) Turn both the intake and exhaust camshaft pulleys
inward at the same time to slacken the timing belt at
position A.
Turning torque : 200 kg-cm (14 ft-lb, 20 N*m)
(b) Measure the timing belt deflection as shown.
Belt deflection at 2 - 3 kg (4.4 - 6.6 lb, 20 - 29 N):
Cold Used belt 5 - 7 mm (0.20 - 0.28 in.)
New belt 4 - 6 mm (0.16 - 0.24 in.1
Hot (Reference) 3 - 5 mm (0.12 - 0.20 in.)
If the measurement is not within specification, adjust by
the idler pulley.

NOTE:
0 “New belt” refers to a belt which has been used less
than 5 minutes on a running engine.
0 “Used belt” refers to a belt which has been used on a
running engine for 5 minutes or more.
0 After installing the drive belt, check that it fits properly
in the ribbed grooves. l Check by hand to confirm that the belt has not slipped
out of the groove on the bottom of the crank pulley.
l After installing the belt, run the engine for approx. 5
minutes and then recheck the deflection.
