INSTALLATION
1. Check that timing marks of crankshaft sprocket B and
balancer shaft sprocket are aligned with each other.
2. Install timing belt B to crankshaft sprocket B and balancer
shaft sprocket. Prevent the tension side of the belt from
sagging.
3. Position the center of the timing belt tensioner B at the
center or upper left of the mounting bolt and flange pulley
at the engine front to assemble and fix them temporarily.
4. Adjust the tension of timing belt B.
"BATIMING BELT B TENSION ADJUSTMENT
1. Apply force to the timing belt B tensioner in the direction
indicated by the arrow to give tension torque (3.0±0.4
N·m) to the timing belt B so that the tension side of the
timing belt B can become tense. Maintaining the condition,
tighten the mounting bolt to the specified torque for fixing.
Tightening Torque: 19±3 N·m
Caution
Be careful not to let the tensioner rotate together when
tightening the mounting bolt. If the tensioner rotates
together, belt tension becomes too much.
2. Measure the tension of timing belt B by following
procedures.

(the place indicated by the arrow) with your finger
as shown in the illustration and check that the vibration
frequency of the belt is within the standard value.
Caution
1) If strong gusts of wind blow against the
microphone or if there are any loud sources
of noise nearby, the values measured by the
microphone may not correspond to actual
values.
2) If the microphone is touching the belt while
the measurement is being made, the values
measured by the microphone may not
correspond to actual values.

Apply a force of approx.100N to the middle (arrow part)
of pulley shown in the figure, and check that the deflection
is within the standard value.
3. If it is outside the standard value, re-adjust belt tension.
