Troubleshooting, Adjustment & Service

Pump Drive Belt Removal

1.Park the tractor on a smooth, level surface such as a concrete floor. Disengage the PTO, engage the parking brake, turn off the engine, and remove the ignition key.

2.Remove the clutch belts (see CLUTCH BELT REMOVAL for instructions).

3.Using a 1/2” breaker bar, place the square end in the square hole located in the middle of the idler arm (A, Figures 53). Carefully rotate the breaker bar counter-clockwise, which will relieve the tension on the belts exerted from the idler arm.

WARNING

Use extreme caution when rotating the idler arm with the breaker bar, due to the increased tension in the spring as the idler arm is being rotated. Injury may result if the breaker bar is prematurely released while the spring is under tension.

4.Remove the belts from the right-hand and left-hand pump drive pulley grooves.

5.Carefully release the tension on the breaker bar until the idler arm stops against the left-hand pump drive pulley.

6.Remove the belts from the crankshaft pulley grooves and pull over the top of the clutch.

Pump Drive Belt Replacement

1.Place the belts over the clutch into the crankshaft pulley grooves.

2.Carefully rotate the idler arm with the breaker bar counter-clockwise (see Figure 53) and wrap the belts around the bottom side of the idler arm pulley and place the belts in the left-hand pump pulley grooves.

4.While holding the breaker bar firmly, place the belts in the right-hand pump pulley grooves.

5.Carefully release the tension on the breaker bar.

6.Inspect the belt path making sure that all belts are properly seated in the pulley grooves.

7.Reinstall the clutch belts (see CLUTCH BELT REPLACEMENT & ADJUSTMENT for instructions).
