DRIVE BELT REPLACEMENT

Generator Drive Belt

1. Remove the engine cover. (See ENGINE COVER REMOVAL/INSTALLATION.)

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})

New (mm {in})	When adjusting (mm {in})
4.0-4.5 {0.16-0.17}	4.5-5.0 {0.18-0.19}

Drive belt tension (when using the SST)

New (N {kgf, lbf})	When adjusting (N {kgf, lbf})
620-767 {63.3-78.2, 140-172}	519-666 {53.0-67.9, 117-149}

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: 20-30 N·m {2.1-3.0 kgf·m, 15-22 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. (See ENGINE COVER REMOVAL/INSTALLATION.)

A/C Drive Belt

1. Remove the engine cover. (See ENGINE COVER REMOVAL/INSTALLATION.)

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})

New (mm {in})	When adjusting (mm {in})
3.0-3.8 {0.11-0.14}	3.3-4.0 {0.13-0.15}

Drive belt tension (when using the SST)

New (N {kgf, lbf})	When adjusting (N {kgf,lbf})
559-706 {57.1-71.9, 126-158}	519-617 {53.0-62.9, 117-138}

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. (See ENGINE COVER REMOVAL/INSTALLATION.)
