• Pivot the double-idler bracket forward slightly
before removing the idler extension spring from the
stud and the double-idler bracket itself. Do NOT

Remove the hex bolt from the center of the electric
PTO clutch and gently lower it off of the engine
crankshaft.
• Be careful not to lose any washers or spacers
which may be found on top of the electric PTO
clutch.
• The engine pulley is located directly above the
electric PTO clutch. Lower the engine pulley far
enough to be able to remove the upper drive belt
from around it..
IMPORTANT:
When remounting the electric PTO clutch,
make certain that is properly oriented against the anti-
rotation bracke prior to securing it to the engine’s
crankshaft. Torque the center hex bolt to between 38
foot-pounds and 50 foot-pounds.
• Remove the drive belt by feeding it from front to
rear, toward the hydrostatic transmission. See

off of the transmission pulley and over the cooling
fan.
IMPORTANT:
The fins on the cooling fan are only slightly
flexible. Be careful not to damage the fan when
removing the drive belt from around the transmission
pulley.
• Reroute the new belt around the pulleys and belt
keepers, if present, EXACTLY as the old one was
routed. Refer to Figure 20.
