2. Adjust steering lock stops
a) Check the steering cylinder ball joint locknut as this is paint marked at the factory – if the
paint mark is intact it would suggest no prior adjustment has been undertaken, so the lock
stops will not require adjustment – If this is the case, please proceed directly to item 3. If
the marks are disturbed continue as follows.
b) Slacken the lock nuts and adjust the steering lock stops (4 in total) to a minimum setting
(the head of the lock stop setscrew should contact the king pin/hub assembly in the
minimum setting).
c) Start the vehicle engine and engage 4WS, ensuring the vehicle remains stable and fully
supported on the axle stands (It may be necessary to raise the rear of the vehicle as well
as the front due to ground conditions) steer the vehicle to the left until the rear steering just
contacts the appropriate rear steering lock stops – at this point no further steering wheel
movement should be undertaken and the vehicles engine switched off.
d) In this position the appropriate front axle steering locks can be adjusted until they contact
the axle beam and the lock nuts secured. (Rear adjuster on the left hand side and front
adjuster on the right hand side).
e) Start the vehicle engine, ensuring 4WS is engaged and the vehicle remains stable and fully
supported on the axle stands steer the vehicle to the right until the rear steering just
contacts the appropriate lock stops – at this point no further steering wheel movement
should be undertaken and the vehicles engine switched off.
f) In this position the appropriate front axle steering locks can be adjusted until they contact
the axle beam and the lock nuts secured. (Front adjuster on the left hand side and rear
adjuster on the right hand side).
g) Start the vehicle engine, ensure the vehicle remains stable and fully supported on the axle
stands, disengage 4WS and centralise the rear steering and turn off the engine.
3. Adjust cylinder ball joint
a) Steer the vehicle to the full right hand lock.
b) Release the steering cylinder ball joint lock nut.
c) Adjust the ball joint/cylinder length by rotating the cylinder rod until the cylinder is at its
maximum extension whilst the steering remains against the right hand steering lock stops.
d) Re-secure the steering cylinder ball joint lock nut and mark with paint pen to indicate the
unit has been adjusted.
e) Start the vehicle engine and engage 4WS, ensuring the vehicle remains stable and fully
supported on the axle stands (It may be necessary to raise the rear of the vehicle as well
as the front due to ground conditions) steer the vehicle to the left until the rear steering just
contacts the appropriate rear steering lock stops – at this point no further steering wheel
movement should be undertaken and the vehicles engine switched off.
