PTO Belt Replacement
NOTE: The PTO belts are a matched set and must be
replaced as a set. If the belts are being removed for
inspection, make sure they are reinstalled in the their
original pulley groove and rotational orientation.
1. Park the tractor on a level surface. Disengage the
PTO, turn off the engine, and set the parking brake.
Remove the key.
2. Tilt the hood forward.
3. Use a spring puller or a small rope loop to remove
the idler arm spring (A, Figure 2 and 3) or release the
tension that is on the idler pulley (D, Figure 1) and
PTO belts (D, Figure 2 and 3).
Note: Check idler pulley for smooth rotation. Pulley
should be square to the belts.
4. Remove the belts (D, Figure 2 and 3), one at a time,
from the lower PTO pulley (E), idler pulley (C), PTO
clutch pulley (B), and the fan (F).
5. Replace the new belts (D), one at a time, on the
lower pulley (E), idler pulley (C), PTO clutch pulley
