Replacing the Drive Belt

If drive belt becomes worn, oil-soaked, excessively cracked,
frayed, or otherwise damaged, replace the belt.

1.

Remove the 4 bolts that hold the drive-belt cover
(

Figure 30

) in place.

Note:

The lower front corner of the drive belt cover

Press down on the idler arm and remove the belt from
between the tab on the idler arm brake and the rotor
pulley.

Note:

The engine pulley belt guide is very close to the

pulley, and the belt may not fit through the gap.

4.

Twist the belt out in front of the belt guide so that the
belt is wedged between the belt guide and the engine
pulley.

5.

Insert a screwdriver into the hole in the belt guide as
shown in

Figure 32

, and flex the belt guide toward the

rotor pulley enough to pull the belt through the gap.

To install the new drive belt, reverse the steps above.

Important:

Ensure that you install the drive belt

so that it sits above the 2 tabs on the idler arm and
below the idler arm brake (

Figure 31

).

7.

Install the drive belt cover with the fasteners that you
removed in step
