Lower Drive Belt
NOTE: Proper removal of the lower drive belt requires

determine if you can successfully complete it.
Otherwise, see an authorized service dealer for the job.

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 16.
Remove the variable-speed pulley by loosening the

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 16.
Model 808H only: Remove the hex bolt from the
center of the engine pulley and gently lower it off
the engine crankshaft. Be careful not to lose any
washers or spacers which may be on top of the
engine pulley.
Model 808K only: 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

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 figures above.
Reassemble by following the above steps in
reverse order.
Reroute the new belt around the pulleys, belt
keepers and keeper pins exactly as the old one was
routed. Refer to Figure 16.
