Belt Maintenance

Replacing the Drive Belt

1. Park the unit on a flat, level surface. Turn off the engine
and disconnect the spark plug wire.
2. Remove the guards.
3. Loosen the nut and bolt that secure the blade belt guides.
Do not remove the hardware completely, only loosen it.
4. Insert the handle of a 3/8" drive wrench into the
transmission drive belt idler arm (B, Figure 5). Use the
wrench handle to turn the idler arm clockwise (from an
aerial view orientation). This step provides the leverage
needed to remove the belt from the engine drive pulley
(A).

drive pulley (A).
