HYDRO DRIVE LINKAGE ADJUSTMENT
4. Loosen the nut against the neutral control linkage yoke as shown in
Figure 12.
5. Adjust the neutral control linkage until the respective drive wheel stops
when the lever is pulled against the neutral spring (neutral position).
Turn the adjusting bolt approximately 1/4 turn clockwise if the wheel is
turning in reverse or turn the bolt approximately 1/4 turn counter-
clockwise if the wheel is turning forward. Release the drive lever to the
forward drive position and squeeze back into the neutral position.
Check to see if the wheel stops. If not, repeat the above adjustment
procedure.
6. Make this adjustment on both sides.
7. After adjustments are made and the wheels stop when the drive lever is
in the neutral position, tighten the nut against the yokes.
c)
Adjust Hydro Control Linkage:
1. Place the speed control lever in the “neutral” position. This adjustment
is again made with rear of machine on jack stands and engine running
at full throttle. OPC levers will have to be held down whenever speed
control lever is moved out of neutral position.
Note: The neutral lock latches should still be “unlocked” and in the
“forward” position.
2. Loosen the front nut on
left
hydro control link as shown in Figure 13. Turn
the rear control linkage adjusting nut counter-clockwise until wheel rotates
forward. Turn the rear nut of left control link clockwise 1/4 of a turn at a
time, stopping to move the speed control forward and back to neutral, until
left wheel
stops rotating forward. Turn the nut an additional 1/2 turn and
tighten the front jam nut making sure not to put a bind on the linkage.
Make sure flat part of linkage is perpendicular to pin part of swivel. See
Figure 12.
