(1) After turning the crankshaft of a revolution in the
counterclockwise direction, turn it in the clockwise direction
. until the timing marks are aligned.
(2) Loosen the tension pulley fixing bolt, and then use the
special tool and a torque wrench to tighten the fix ing
bolt to the specified torque while applying tension to the
timing belt.
Standard value:
3.5 Nm (2.6

Caution
When tightening the fixing bolt, ‘do

INSTALLATION SERVICE POINTS
BELT INSTALLATION
Install’ timing belt “B” by the following procedure .
(1) Ensure that crankshaft sprocket “B” timing mark and the
counterbalance shaft sprocket timing mark are align ed.
(2) Fit timing belt “B” over crankshaft sprocket
and the
silent shaft sprocket. Ensure that there is no slac k in
the belt.
BELT TENSION ADJUSTMENT
Adjust the tension of timing belt by the following procedure.
(1) Temporarily fix the timing belt “B” tensioner s uch that
the center of the tensioner pulley is to the left and above
the center of the installation bolt, and temporarily attach
the tensioner pulley so that the flange the front
of the engine.
Holding the timing belt “B” tensioner your finger
in the direction arrow, place the
belt so that the tension side of the taut. Now tighten
the bolt to fix the tensioner.
Caution
When tightening the bolt, ‘the tensioner
pulley shaft does not rotate

NOTE
(1) Water or oil on the belt shorten its life drast ically,
so the removed timing belt, sprocket, and tensioner
must be free from oil and water. These parts should
not be washed. Replace parts if seriously contami-
nated.
(2) If there is oil or water on each part check fro nt case
oil seals, camshaft oil seal and water pump for lea ks.
