Check the condition of the drive belt annually or after every 25 hours of operating, whichever comes first. If the belt is

cracked, frayed, or worn, replace it. To replace or adjust drive belt, proceed as follows:

1. Remove the belt shield, upper belt guide (6) and lower belt guard (5).
2. Remove idler pulley (2).
3.

Slip the drive belt off the belt pulleys.

4. Inspect pulleys for wear. Replace the pulleys

if they are cracked or worn so that the belt

contact area is not smooth and flat.

5. Place the new belt over pulleys. Do not force

or pry the belt over pulleys as this may cause

cord breakage.

6. Reinstall the idler pulley, ensuring that the belt

is on the outside edge of the idler pulley.

7. Check all pulleys to make sure they are

properly aligned.

8. Replace all shields, guides and guards.

1.  Remove discharge door/shield, discharge screen and rotor shaft end cap on chute side of the machine.
2.  Loosen the set screws on the lock collar securing the chute side bearing on the rotor shaft.
3.  Using a punch and hammer, tap the lock collar in the opposite direction of normal rotation until loose; remove lock

collar and bearing.

5.  Remove the drive belt.
6.  Loosen the set screws holding the belt pulley on the rotor shaft and remove the pulley.
7.  Repeat steps 2 and 3 on the engine side rotor bearing.
