BELT REMOVAL & REPLACEMENT

WARNING

If servicing the belts after the engine has been running, use extreme caution when raising the hood or lowering the rear shield. The surface of the hood and rear shield can be hot from the muffler and exhaust manifold.

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 PTO drive belt from the clutch (see PTO DRIVE 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 49). Carefully rotate the breaker

bar COUNTER-CLOCKWISE, which will relieve the tension on the belts exerted from the idler arm.

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

5.Carefully release the tension on the breaker bar.

6.Unhook the spring (B) from the anchor bolt on the idler arm.

7.Remove the belts from the crankshaft pulley grooves and pull out from behind the clutch.

Pump Drive Belt Replacement

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

2.Wrap the belts around the top side of the idler arm pulley and install the belts in the right-hand pump pulley grooves.

3.Reinstall the spring onto the anchor bolt on the idler arm.

4.Carefully rotate the idler arm with the breaker bar counter-clockwise (see Figure 49). While holding the breaker bar firmly, install the belts in the left- hand pump pulley grooves and the two stationary idler pulleys 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 PTO drive belt from the clutch (see PTO DRIVE BELT REPLACEMENT for instructions).

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.
