Upper Drive Belt
• Locate the transmission idler pulley on the
upper drive belt by looking through the battery
tray opening. See Figure 17.
• Pivot the transmission idler pulley toward the
rear of the tractor to release tension on the
upper drive belt.
• Remove the belt from around the transmission
idler pulley.
• Remove the upper drive belt from around the
transmission pulley and the variable-speed
pulley.
NOTE: In order to remove the belt from around the
variable-speed pulley, slowly rotate the pulley
counterclockwise while rolling the belt off of it.
• Remove the upper drive belt by pulling it up
through the battery tray opening.
• Reroute the new upper drive belt as shown in
Figure 17 unless proceeding with the lower
drive belt removal.
Lower Drive Belt
NOTE: Proper removal of the lower drive belt
requires the removal of several tractor components.
Read through the following procedure prior to
attempting it to determine if you feel you could
successfully complete it. If you don’t, see your Cub
Cadet dealer to have the belt changed.
IMPORTANT: Note the routing of the lower drive
belt around both the pulleys and the belt keepers
BEFORE performing the following steps.
• Remove the upper drive belt following the
instructions above.
• Locate the variable-speed pulley by looking
through the battery tray opening. See Figure
17. Remove the variable-speed pulley by
loosening the hex bolt that affixes the pulley to
the variable-speed bracket.
• Remove the belt keeper found directly behind
the variable-speed pulley.
• Slide the belt off of the variable-speed pulley
as you lift the pulley up and out through the
battery tray opening.
NOTE: Jacking the rear of the tractor up off the
ground at this point in the procedure will ease the
following steps, but is not necessary. Remove the
rear idler pulley from the double idler bracket while
unrouting the belt from around both the rear and the
front idler pulley. Refer to Figure 17.
• Remove the rear idler pulley from the double-
idler bracket while unrouting the belt from
around both the rear and the front idler pulley.
Refer to Figure 17.
• Carefully unplug the tractor’s wire harness
from the connector on the electric PTO clutch.
See Figure 18.
Figure 18
• Remove the hex bolt from the center of the
electric PTO clutch and gently lower the
electric PTO clutch off of the engine
crankshaft. Be careful not to lose any flat
washers which may be found on top of the
electric PTO clutch. See Figure 18.
• 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, torque the center hex bolt to between 38
foot-pounds and 50 foot-pounds.
• Remove the drive belt by feeding it from both
ends toward the front idler pulley on the
double-idler bracket. See Figure 17.
NOTE: It IS necessary to remove the shift cover
on the front of the fender and feed the belt through
and around the shift lever to remove the belt.
• Reassemble by following the above steps in
reverse order.
• Reroute the new belt (part # 754-0467)
around the pulleys, keeper pins and belt
keepers EXACTLY as the old one was routed.
Refer to Figure 17.
