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 20.
•
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 20.
•
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.
•
Note the orientation of the electric PTO clutch.
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
Figure 20.
•
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 20.
