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. Loosen and remove the crankshaft bolt (C, Figure 43)

and the PTO clutch (B) from the engine crankshaft.

4. Loosen the nut on the spring anchor eyebolt (G, Figure

44) to release the majority of the belt tension. Use
caution and remove the nut to completely release the
tension.

WARNING

STORED ENERGY DEVICE: Improper release of the belt
tension spring can result in personal injury.
Use extreme caution when removing this spring.

5. Remove the old belt and replace it with the new one.

Make sure the V-side of the belt runs in the grooves of
the crankshaft pulley and the transmission pulleys (B &
C).

6. Reinstall the spring anchor eyebolt (G) into the anchor

tab and loosely fasten the nut. Adjust the anchor
eyebolt until a measurement of 5-7/8” (14,92 cm) is
achieved from the outside if the spring hooks. Tighten
nut.

7. Reinstall the PTO clutch to the engine crankshaft and

secure with the crankshaft bolt. Tighten the crankshaft
bolt to 65 ft. lbs (88 Nm).

NOTE: Make sure that the slot in the PTO clutch lines up
with the PTO clutch mounting tab (A, Figure 43) underneath
the engine deck.

8. Reinstall the PTO drive belt.
