(12)Install the special tool and a torque wrench to the tensioner
pulley.
(13)Using torque wrench, torque to 2.6 Nm.
(14)While holding the tensioner pulley to prevent it from
turning, tighten the center bolt to the specified torque.
(15)Give two clockwise turns to the crankshaft and leave
as it is for approx. 15 minutes.
(16)Check if the Allen wrench inserted during installation of
the auto-tensioner can be pulled out lightly. If it can be
pulled out lightly, the belt is properly tensioned. Therefore,
pull out the wrench. The belt is also properly tensioned
if the auto-tensioner projection is of standard value.
Standard value: 3.8 – 4.5 mm
(17)If the wrench cannot be pulled out lightly, repeat the steps
(12) through (15) to obtain appropriate belt tension.
NOTE
Check the tightening torque of the crankshaft bolt always
after rotating the crankshaft counterclockwise using the
crankshaft bolt. Retighten the bolt if the tightening torque
is not up to specification.
