<<B>> TIMING BELT B REMOVAL

CAUTION

If the belt is to be re-used, mark an arrow on the belt with
chalk indicating the clockwise direction of rotation.

INSTALLATION SERVICE POINTS

>>A<< TIMING BELT B INSTALLATION
1. Ensure that crankshaft sprocket B timing marks and the

counterbalance shaft sprocket timing marks 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.

>>B<< CRANKSHAFT SENSING BLADE/CRANKSHAFT
SPROCKET INSTALLATION
1. To prevent the crankshaft bolt from loosening, degrease or

clean the seating surfaces of the crankshaft, crankshaft
sprocket B, crankshaft sensing blade and crankshaft at the
shown positions.

2. Install the crankshaft sensing blade so that they face as

shown in the illustration.

3. Apply the minimum amount of engine oil to the seat surface

and thread of the crankshaft bolt.

4. Use the crankshaft pulley mounting bolt to secure special

tool MB991367.

5. Tighten the crankshaft sprocket bolt to the specified torque.

>>C<< TIMING BELT B TENSION ADJUSTMENT
1. Temporarily fix the timing belt B tensioner so the center of

the tensioner pulley is to the left and above the center of the
mounting bolt. Temporarily attach the tensioner pulley so the
flange is toward the front of the engine.

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 bolt.
2. Holding the timing belt B tensioner up with your finger in the

direction of the arrow, apply pressure on the timing belt so
the tension side of the belt is taut. Now tighten the bolt to fix
the tensioner.

Tightening torque: 19 N

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

A) with a finger. Adjust the belt tension if it is incorrect.
