4-8.9 Belt Removal and Replacement With Electric
Clutch.
It is not necessary to tip the unit to remove the
belts. However, if tipping the unit is desired,
remove the battery from the unit. To prevent gas-
oline leakage, drain the gasoline, or remove the
fuel tank cap, place a thin piece of plastic over
the neck of the fuel tank and screw on the cap.
Be certain to remove the plastic when finished
changing the belts. Block unit securely. Replace
belts as follows:
On early 1990 units with an electric clutch, if the
unit fails to stop under a heavy load, order a new
drive belt (part number 754-0358A). Also, the
pitch of the engine pulley may be too narrow
causing the belt to bind. Order a new engine pul-
ley using the same part number that is in the
Owner's Guide.
Disconnect the spark plug wire and ground it
against the engine. Block the wheels of the unit.
1. Rear drive belt. Remove and replace rear belt as
follows:
a. Unscrew parking brake knob. Remove the
two truss head screws which secure the
transmission cover. Remove transmission
panel.
b. Disconnect the speed selector rod from the
variable speed pulley by removing the cotter
pin and flat washer and lifting rod off the 3/8
inch pin. See Figure 4-44.
c. Push the idler pulley toward the right side of
the unit. Lift the belt over the idler pulley.
d. Remove the belt from the variable speed pul-
ley and transmission pulley.
e. Replace belt and reassemble in reverse
order.

est position.
