Governor System
The governor system is a flyweight type, and regulates vehicle ground speed. It is mounted inside the unit-
ized transaxle and is driven by transaxle gears. Because the governor is mounted inside the transaxle, it is
protected from abuse and damage common to externally mounted governor systems. If any of the governor
linkages are removed in order to service other components, readjustment of the governor linkage is required.
See Governor Cable Installation and Adjustment, Section 14, Page 14-10.
Unitized Transaxle Service
The unitized transaxle is extremely durable and should require very little service under normal operating con-
ditions. The only maintenance required on the unitized transaxle is to maintain proper lubricant level. See
Periodic Lubrication Schedule, Section 10, Page 10-4. Under normal operating conditions, adjustment to
the system should not be required.
Tools Required For This Section
LUBRICATION
There are two plugs located on the right (driven clutch) side of the unitized transaxle (Figure 16-2, Page 16-
2). When the vehicle is on a level surface, the upper plug is used as a lubricant level indicator. Lubricant level
should be even with the bottom of level indicator hole. The lower plug is used for draining lubricant from the
transaxle. When draining lubricant, both plugs should be removed to allow the lubricant to drain faster. Be
sure the drain plug and gasket are cleaned and reinstalled before filling the transaxle with new lubricant.
Tighten the plug to 20 ft-lb (27.1 N·m). Use a funnel when filling the transaxle through the lubricant level indi-
cator hole. Fill with 31 oz. (.92 liters) 80-90 Wt. API class GL-3 or 80-90 Wt. AGMA class 5 EP gear lubricant
(or until lubricant begins to run out of the level indicator hole).
AXLE SHAFT
Read DANGER and WARNING on page 16-1.
Removal of the unitized transaxle is not required for servicing or replacing axle shafts, axle bearings, or axle
shaft oil seals. If the unitized transaxle is to be removed from the vehicle, then
do not remove the wheels, axle
shafts, or axle tubes first. Instructions for removing the unitized transaxle from the vehicle begin on page 16-7.
