If you don’t, see your authorized dealer to have the belt
changed.
IMPORTANT:
Note the routing of the lower drive belt
around all the pulleys and the belt keepers (if present)
BEFORE performing the following steps.
•
Locate the fixed v-idler pulley found on the left
underside of the frame. See Figure 22.
•
Grasp the belt on both sides of the pulley and gently
move it toward the left frame rail allowing it to
unseat itself from the fixed v-idler. See Figure 22.
•
Pivot the double-idler bracket forward slightly
before removing the idler extension spring from the
stud and the double-idler bracket itself. Do NOT
discard the spring.
•
Roll the drive belt out from around both the v-idler
pulley and the flat idler pulley found on the double-
idler bracket.
•
Carefully unplug the tractor’s wire harness from the
connector on the electric PTO clutch (if present).
•
Remove the hex bolt from the center of the electric
PTO clutch (or the engine pulley) 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 or engine pulley.
•
On units equipped with an electric PTO, 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.
Figure 22
IMPORTANT:
When remounting the electric PTO
clutch (or engine pulley), 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
Figure 22.
•
Continue removing the drive belt by gently lifting it
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 22.
Hydrostatic Transmission
The hydrostatic transmission is sealed at the factory
and is maintenance free. The fluid level cannot be
checked nor can the oil be changed. Always keep the
area around the transmission cooling fan free of grass
and debris at all times.
