6) Install the timing belt guide. (MT model)
(1) Temporarily tighten the bolts mounting the
timing belt guide.
(2) Check and adjust the clearance between
timing belt and timing belt guide by using thick-
ness gauge.
Clearance:
1.0
±
0.5 mm (0.039
±
0.020 in)
(3) Tighten the bolts mounting the timing belt
guide.
Tightening torque:
9.75 N·m (1.0 kgf-m, 7.2 ft-lb)
7) Install the timing belt cover.

9) Install the V-belts. <Ref. to ME(H4SO)-36, IN-
STALLATION, V-belt.>
C: INSPECTION
1. TIMING BELT
1) Check the timing belt teeth for breaks, cracks or
wear. If any fault is found, replace the belt.
2) Check the condition of the backside of belt. If
cracks are found, replace the belt.
CAUTION:
• Be careful not to let oil, grease or coolant
contact the belt. Remove quickly and thorough-
ly if this happens.
• Do not bend the timing belt sharply.
In radial diameter h:
60 mm (2.36 in) or more
2. AUTOMATIC BELT TENSION ADJUST-
ER
1) Visually check the oil seals for leaks, and rod
ends for abnormal wear and scratches. If neces-
sary, replace the automatic belt tension adjuster
assembly.
NOTE:
Slight traces of oil at rod’s oil seal does not indicate
a problem.
2) Check that the adjuster rod does not move when
a pressure of 165 N (16.8 kgf, 37.1 lb) is applied to
it. This is to check adjuster rod stiffness.
3) If the adjuster rod is not stiff and moves freely
when applying 165 N (16.8 kgf, 37.1 lb), check it us-
ing the following procedures:
(1) Slowly press the adjuster rod down to the
end surface of cylinder. Repeat this operation
two to three times.
(2) With the adjuster rod moved all the way up,
apply a pressure of 165 N (16.8 kgf, 37.1 lb) to
it. Check the adjuster rod stiffness.
