The engine must be stopped, the parking brake applied and the front wheels chocked.
Lift one end of the machine until the tyres are clear of the ground. Loosen the two clamps at either end of the
axle beam.
Caution: Ensure the machine is well supported. A single jack under the centre of the front axle is not
acceptable.
Remove the four bolts in the bottom of the axle beam.
Remove the two track rod adjusting bolts.
In the bottom face of the axle beam are two slots and in each slot is a screwed stop (screwed into the sliding
leg). If the stop is allowed to slide from one side of the slot to the other then the movement will be 6” (152mm).
This equates to 12” (305mm) over the complete axle. However, if the stop is moved to either of the two other
positions within the slot then the movement is reduced to 4” (102mm) or 2” (52mm).
On the front axle suspension plate is a hydraulic valve. With the manual handle supplied, raise the valve
manual control fully up.
Start the engine and turn the steering wheel in the appropriate direction to slide the axles to the correct
position (at the fullest extent of the slot).
Note: It is normal for only one axle leg to move at a time. When the first leg moves to its fullest extent the
second leg will start to move providing the steering wheel continues to be turned.
Pull the track rods to the correct position and refit the securing bolts.
Refit and lightly tighten the four screws in the bottom of the axle beam. Lightly re-tighten the clamps at the
end of the axle beam. Lower the machine to the ground and fully tighten clamps and fixing screws.
Repeat this exercise on the second axle. When complete, reset the hydraulic valve fully down. This hydraulic
valve is fail-safe and will also reset itself when the parking brakes are released.
