“a”: 2 - 10 mm (0.08 - 0.40 in.)

ii) Measure timing belt tension flipping timing 

belt by finger as shown in figure.
If timing belt tension is out of specification 
below, adjust timing belt tension by 
tightening / loosening adjusting bolt (1) and 
return to Step c).

Timing belt tension (Frequency displayed 
on special tool):
 87 – 93 Hz

e) Tighten timing belt tensioner pulley nut (3) to 10 

N

⋅m (1.0 kgf-m, 7.5 lb-ft) temporarily.

f) Turn crankshaft two revolutions clockwise until 

mark (1) of camshaft pulley (2) matches with 
mark (3) of timing belt inner cover (4).

g) Check that special tool (A) can be inserted into 

TDC pin hole smoothly.

h) Remove special tool (A).
i)
