Drive Belt: Service and Repair
DRIVE BELT REPLACEMENTGenerator 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 lbf}):
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 N-m {3.9 - 5.2 kgf.m, 29 - 37 ft.lbf}
B: 18.6 - 25.5 N-m {1.90 - 2.60 kgf.m, 13.8 - 18.8 ft.lbf}
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.
Drive Belt Deflection (with Pressure Of 98 N {10 kgf, 22 lbf}):
Drive Belt Tension (when Using The SST):
5. Tighten idle pulley locknut A to the specified torque.
Tightening torque: 37.2 - 51.9 N-m {3.80 - 5.29 kgf.m, 27.5 - 38.2 ft.lbf}
6. Crank the engine and measure the deflection and tension again. If not within the specification, repeat from Step 2 again.
7. Install the engine cover.
