TRANSMISSION DRIVE BELT REPLACEMENT

To avoid damaging belts, DO NOT

PRY BELTS OVER PULLEYS.

1.Park the rider on a smooth, level surface such as a concrete floor. Disengage the PTO, lock the motion control levers into their neutral locked positions, turn off the engine, and remove the ignition key.

2.Remove the mower belt from the PTO pulley (see MOWER BELT REPLACEMENT for instructions).

3.Relieve tension on the transmission belt (A, Figure 21) by moving the idler arm (E) in the direction indi- cated by the curved arrow, and remove the old belt from the crankshaft and transmission pulleys.

4.Loosen (do not remove) the anti-rotation bracket hardware (C, Figure 22), and slip the old belt out between the anti-rotation pin (B) and the PTO (A).

Note: The PTO wiring harness must be disconnected from the main wiring harness in order to remove and replace the transmission belt. Be sure to reconnect the harness after the belt is replaced.

5.Reversing steps 3-4, install the new belt, following the routing in Figure 24. Make sure the V-side of the belt runs in the grooves of the crankshaft pulley and transmission pulleys (B & C). Also, make sure that the anti-rotation pin (B, Figure 22) is inserted into the anti-rotation slot on the PTO before tightening hard- ware (C).

6.Reinstall the PTO drive belt.
