4.  Loosen adjusting bolt C and remove the drive belt.

5.  Install the drive belt and adjust the drive belt deflection/tension 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}

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: 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/tension again. If not within the specification, repeat from Step 3 again.

8.  Install the A/C drive belt. (See A/C Drive Belt.)

9.  Install the engine cover. (See ENGINE COVER REMOVAL/INSTALLATION [13B-MSP].)


A/C Drive Belt

1.  Remove the engine cover. (See ENGINE COVER REMOVAL/INSTALLATION [13B-MSP].)

2.  Loosen A/C drive belt tensioner pulley locknut A.

3.  Loosen adjusting bolt B and remove the belt.

4.  Install the drive belt and adjust the drive belt deflection/tension 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.

6.  Crank the engine and measure the deflection/tension again. If not within the specification, repeat from Step 2 again.

7.  Install the engine cover. (See ENGINE COVER REMOVAL/INSTALLATION [13B-MSP].)
