Pump Belt

The belts are not adjustable. Replace belts if they begin to slip from wear.

Replacing Pump Belt

Park the mower on a level surface. Engage the parking brake.

Belt Removal

From the top side of the deck:

1.Remove the deck belt (see Deck Belt Removal in this section of the manual).

2.Tilt seat forward to access fan covers. Remove both fan covers.

From the underside of the mower:

3.Remove clutch stop to access the belt.

4.With a ½" breaker bar and using the square opening in the pump idler arm, shift the arm to create slack in the belt.

5.With the idler arm in the slack position, slip a screwdriver, clevis pin or similar into the 3/8" hole in the plate that sits between the two fan covers. This will keep the idler in the extended position and allow removal of the breaker bar.

6.Remove belt from the engine and pump pulleys over the top of the fans.

Belt Installation

1.If the pump is not locked in the extended position, repeat Steps 4 and 5 from the above instructions.

2.Slip the belt over the fans and route it between the idler pulleys.

3.Place the belt over the right and left idler pulleys.

4.Place the belt on the engine pulley.

5.Use the breaker bar to hold the tension off the belt while removing the implement used as a brace in the plate.

6.Replace and secure clutch stop.

7.Reinstall the fan shields.

8.Reinstall the deck belt. (See Deck Belt Installation in this section of the manual).
