INSTALLATION SERVICE POINTS

TIMING BELT B INSTALLATION, ADJUSTMENT

1. Install 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 the tension of 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 on the belt.

3. To ensure that the tension is correct, depress the belt

(point A) with a finger. If not, adjust.

Standard value: 5 - 7 mm
