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
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 48). 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 48). 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 clutch belts (see CLUTCH 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.
