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 42). 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 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 42) 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).

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.
