HYDRAULIC PUMP DRIVE BELT REPLACEMENT

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 (see MOWER BELT REPLACEMENT for removal instructions).

3.Remove the hardware that secures the clutch anchor pad to the PTO clutch.

4.Loosen the nut towards the front of the machine on the spring anchor hook (G, Figure 43) to release the majority of the belt tension. Use caution and remove the nut to completely release the tension.

5.Remove the old belt and replace it with a new one. Make sure the V-side of the belt runs in the grooves of the crankshaft pulley and pump pulleys (B & C).

6.Reinstall the anchor hook (G) into the anchor tab and loosely fasten the nut. Adjust the anchor hook until a measurement of 8-3/8” (21,2 cm) is achieved from the outside if the spring hooks. Tighten nut.

7.Reinstall the clutch anchor pad to the PTO clutch and secure with the hardware previously removed.

8.Reinstall the PTO drive belt.
