TIMING BELT B INSTALLATION
1. Install the timing belt “B” by the following procedure.
(1) Ensure that crankshaft sprocket “B” timing mark and
the counterbalance shaft sprocket timing mark are
aligned.
(2) Fit timing belt “B” over crankshaft sprocket “B” and
the counterbalance shaft sprocket. Ensure that there
is no slack in the belt.
2. Adjust timing belt “B” by the following procedure,
(1) Temporarily fix the timing belt “B” tensioner such that
the centre of the tensioner pulley is to the left and
above the centre of the installation bolt, and
temporarily attach the tensioner pulley so that the
flange is toward the front of the engine.
(2) Holding the timing belt “B” tensioner up with your
finger in the direction of the arrow, place pressure
on the timing belt so that the tension side of the
belt is taut. Now tighten the bolt to fix the tensioner.
Caution
When tightening the bolt, ensure that the tensioner
pulley shaft does not rotate with the bolt. Allowing
it to rotate with the bolt can cause excessive
tension of the belt.
(3) Check to ensure that when centre of span on tension
side is depressed with index finger in direction of
arrow, tension of belt is up to specification.
