1.
Make sure all moving parts have stopped, parking brake
is engaged, and the key has been removed.
2.
Remove and retain rear bumper and its mounting
hardware.
3.
Loosen the mule drive idler pulley on the right hand
side of the unit so it can slide upward in the slot.

Place a wrench on the 3/8 inch nut in the center of the
spring loaded idler pulley and apply upward pressure
to relieve the belt tension.
Note:
1/2 inch breaker bar with a 9/16 inch socket
works best.
5.
Carefully remove the belt from the idler pulley groove,
and SLOWLY release the spring pressure.
6.
Remove and discard the spring and its mounting
hardware.
7.
