IMPORTANT: Note the routing of the lower drive belt
around both the pulleys and the belt keepers before
performing the following steps.
• Locate the variable-speed pulley through the
battery tray opening. See Figure 17.
• Remove the variable-speed pulley by loosening the
hex bolt that secures itto the transmission. Use a
second wrench to hold the hex nut on the bottom
side of the pulley.
• Slide the belt off the variable-speed pulley as you
lift the pulley up and out through the battery tray
opening.
• Remove rear idler pulley from the double- idler
bracket while loosening the belt from around both
the rear and the front idler pulleys. See Figure 17.
• Remove the hex bolt from the center of the electric
PTO clutch and gently lower it off the engine
crankshaft. Be careful not to lose any washers or
which may be found on top of the PTO clutch.
IMPORTANT: When remounting the 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 18.
