When making adjustments to the Speed Control system, block the buggy’s wheels in both
directions to prevent injury.
1. Adjust Speed Control Lever, Cable and Spring
(Refer to drawing on page ??)
A. Position the buggy on a hard, level surface. Turn the engine off. Remove spark plug wire(s) to disable engine.
Engage the parking brake.
B. Pull up on the speed control lever to the maximum speed position. Then release the lever. A properly
adjusted speed control lever, cable and spring will permit the speed control lever to snap back briskly to the
Neutral position (the transmission shift bar will be seated firmly against the neutral stop bolt.
C. If the Speed Control Lever does not return properly to the neutral position adjust this assembly as follows.
D. Remove the hydraulic reservoir cover (four(4) 3/8”NC-16 hex bolts and lock washers).
E. Remove the return spring (item 26).
F. Remove the cotter pin (item 12) from the clevis pin (item 11) in the clevis on the transmission shift bar (item
13). Also see item 10. Then remove the clevis pin. Inspect the transmission shift bar to make sure it is secure
on the transmission shaft, the nut is tightened to 22 ft.lb./265 in.lbs. and the woodruff key in the shaft is not
sheared/missing. Repair as required.
G. With the transmission shift bar now disconnected from the shift cable, move the transmission shift bar clock-
wise as facing the bar until it stops. Then rotate the transmission shift bar counter-clockwise until it contacts
the neutral stop bolt. The bar must rotate freely in both directions. If the transmission shift bar does not
rotate freely, return the hydrostatic transmission to an Eaton authorized repair facility or to AEC for service.
H. Inspect the shift cable (item 9). Move the shift lever (item 25) with the cable attached through the full range
of travel. The lever must move freely with no binding or catching. The shift cable must have no physical
damage, i.e., cuts in outer cable covering, missing and/or torn end boots (2 places), etc. Replace the shift
cable if it is damaged and/or does not work freely. Replace the shift cable if it has not been replaced within
the last twenty-four (24) months. When a shift cable is replaced follow the assembly steps and assembly
dimensions as listed below:
i. Remove the bolt/nut (item 24) from the speed control lever holding the swivel cable end in place.
ii. Remove all attachments from both ends of the cable.
iii. Loosen and remove the outside 5/8”NF-18 jam nut(2) from each bulkhead fitting on cable.
iv. Remove shift cable (item 9) and grommet or compression fitting.
v. If machine is equipped with a rubber grommet in top of console where shift cable passes through,
replace the grommet with cord grip (item 30).
vi. Install one(1) 5/8”NF-18 nut on both bulkhead fittings of cable. Thread nut to the far end of bulkhead
fitting.
vii. Install one (1) 1/4” NF-28 jam nut on each end of shift cable. Thread both nuts to end of threaded
rod.
viii. Insert new shift cable in machine. Insert bulkhead fittings on shift cable into their respective mount-
ing holes on the handlebar and hydraulic reservoir end plate.
