ADJUSTMENTS/REPAIRS
FOOT PEDAL/HYDROBACK NEUTRAL ADJUSTMENT
Note:
When servicing the hydrostatic drive system, always check for any machine creeping (movement) when the machine is in neutral with the
engine running. The machine must not move either forward or reverse after the drive pedal is released. If machine creeps in neutral, or if you re-
place the Hydroback, pedal cable or Rotary Sensor, you will need to set the hydrostatic drive neutral position, then recalibrate the neutral deadband
setting.
1
Empty and remove the recovery tank to access the Hydroback Adjuster Plate
(I)
.
CAUTION!
Make sure to follow the instructions in the JACKING THE MACHINE section. Jack the machine at the designated locations only.
2
Block the rear wheels.
3
Jack up the front of the machine until the front drive wheel is off the
fl
oor.
4
Place supports at the front corners of the machine.
5
Start the engine and observe the direction of the drive wheel rotation.
6
Loosen the two 5/16”-18 hex head screws
(C)
holding the Adjuster Plate to the chassis.
7
See Figure 9. Loosen the jam nut and turn the Adjustment Screw
(B)
clockwise or counterclockwise to move the Adjuster Plate and Hydroback
unit
(D)
as required to stop any wheel movement. The Piston Pump Lever Weldment
(E)
on the Piston Pump
(G)
is now in the neutral position.
8
Tighten the two 5/16”-18 hex head screws to secure the Adjuster Plate to the chassis.
9
Tighten the jam nut on the Adjustment Screw.
10
Test the neutral adjustment by activating the drive pedal in both forward and reverse, then letting the drive pedal return to the neutral position.
Readjust the Adjuster Plate neutral position if the neutral setting is not repeatable. If you can’t get a repeatable neutral position, replace the
Hydroback unit and/or Push/Pull Control Cable
(A)
as necessary.
11
Check the maximum forward and reverse wheel speeds and adjust the pedal stops as necessary. Refer to the GENERAL HYDRAULIC SPECI-
FICATIONS TABLE in the HYDRAULIC SYSTEM section for nominal wheel speeds.
12
Turn the engine off, then see if it will restart. If engine will not start, the Rotary Sensor
(F)
is probably out of its neutral (deadband) range and
needs to be recalibrated. See the FOOT PEDAL NEUTRAL/DEADBAND ADJUSTMENT section for programming instructions.
13
Lower the machine and reinstall the recovery tank.
