• Locate the variable-speed pulley through the battery
tray opening. See Figure 27.
• Remove the variable-speed pulley by loosening the
hex bolt that affixes it to the transmission. Use a
second wrench to hold the hex nut on the bottom
side of the pulley.
• Slide the belt off of the variable-speed pulley as you
lift the pulley up and out through the battery tray
opening.
• 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 27.
• Remove the hex bolt from the center of the engine
pulley (or the electric PTO clutch on units so
equipped) 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 engine
pulley.
IMPORTANT: When remounting the engine pulley or
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 27.
• Reassemble by following the above steps in reverse
order.
• Reroute the new belt around the pulleys and belt
keepers EXACTLY as the old one was routed. Refer
to Figure 27.
The drive pedal is properly adjusted when the hole found
in the double-idler bracket has approximately 1-3/8" of
travel with ten pounds of pressure applied to the drive
pedal. See Figure 28.
