1. Park the unit 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.

)
and the PTO clutch (

) to release the majority of the belt tension. Use
caution and remove the nut to completely release the
tension.
5. Remove the old belt and replace it with the new one.
Make sure the V-side of the belt runs in the grooves of
the crankshaft pulley and transmission pulleys (
B & C
).
6. Reinstall the spring anchor eyebolt (
G
) into the anchor
tab and loosely fasten the nut. Adjust the anchor eyebolt
until a measurement of 8-3/8” (21,2 cm) is achieved
from the outside of the spring hooks. Tighten nut.
7. Reinstall the PTO clutch to the engine crankshaft and
secure with the crankshaft bolt. Tighten the crankshaft
bolt to 65 ft. lbs (88 Nm).
NOTE: Make sure that the slot in the PTO clutch lines up
with the PTO clutch mounting tab (

) underneath
the engine deck.
