Drive Belt: Service and Repair

DRIVE BELT REPLACEMENT
Generator Drive Belt





1. Remove the engine cover.
2. Remove the A/C drive belt.
3. Loosen generator installation bolt A and locknut B.
4. Loosen adjusting bolt C and remove the drive belt.
5. Install the drive belt and adjust the drive belt deflection by tightening adjusting bolt C to the specification.

Caution:
^ After replacing with a the new drive belt, assemble with the deflection/tension for new drive belt and operate the drive belt for 1 min or more while idling the engine. Then adjust it to the deflection/tension used when adjusting.





Drive belt deflection (with pressure of 98 N (10 kgf, 22 lbs.)





Drive belt tension (when using the SST)

6. Tighten generator installation bolt A and locknut B to the specified torque.
Tightening torque
A: 38 - 51 Nm (3.9 - 5.2 kgf-cm, 29 - 37 ft lbs.)
B: 20 - 30 Nm (2.1 - 3.0 kgf-cm, 15 - 22 ft. lbs.)
7. Crank the engine and measure the deflection and tension again. If not within the specification, repeat from Step 3 again.
8. Install the A/C drive belt.
9. Install the engine cover.

A/C Drive Belt





1. Remove the engine cover.
2. Loosen idle pulley locknut A.
3. Loosen adjusting bolt B and remove the belt.
4. Install the drive belt and adjust the drive belt deflection by tightening adjusting bolt B to the specification.

Caution:
^ After replacing with a the new drive belt, assemble with the deflection/tension for new drive belt and operate the drive belt for 5 min or more while idling the engine. Then adjust it to the deflection/tension used when adjusting.
