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 clockwise as facing the bar until it stops. Then rotate the transmission shift bar count-
er-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:
1) Remove the bolt/nut (item 24) from the speed control lever holding the swivel cable end in
place.
2) Remove all attachments from both ends of the cable.
3) Loosen and remove the outside 5/8”NF-18 jam nut(2) from each bulkhead fitting on cable.
4) Remove shift cable (item 9) and grommet or compression fitting.
5) 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).
6) Install one(1) 5/8”NF-18 nut on both bulkhead fittings of cable. Thread nut to the far end of
bulkhead fitting.
7) Install one (1) 1/4” NF-28 jam nut on each end of shift cable. Thread both nuts to end of thread-
ed rod.
8) Insert new shift cable in machine. Insert bulkhead fittings on shift cable into their respective
mounting holes on the handlebar and hydraulic reservoir end plate.
