(4) Nut (not shown)
Steer Axle Right End
(5) Nut (6) Setscrew (7) Nut (8) Setscrew
(A) 80 +0-2 Cramp angle (reference)
Use the procedure that follows to adjust the steer
axle turning angle.
1.
Loosen nut (2) and (7) on steer axle ends. Turn
setscrew (1) and (8) all the way in. Put left steer
knuckle in forward cramp until steering cylinder
internal stop is reached. Adjust setscrew (1) of
left end of steer axle and setscrew (8) of right
end of steer to contact steer knuckle. Tighten
nuts (2) and (7) to hold the adjustment.
2.
Loosen nut (5) and (4) on steer axle ends. Turn
setscrew (8) and (3) all the way in. Put right steer
knuckle in forward cramp until steering cylinder
internal stop is reached. Adjust setscrew (6) of
right end of steer axle and setscrew (3) of left
end of steer to contact steer knuckle. Tighten

Steering System Air Removal
1.
Fill the hydraulic Tank or reservoir nearly full. Be
ready to add oil when the engine is started. Do
not let oil level go below the outlet to the pump.
2.
Start the engine and keep at low idle. Add oil
immediately to the tank or reservoir as needed.
NOTE :
This oil will now flow from the pump, the
priority valve and the steering gear, then back to the
priority valve, hydraulic control valve, hydraulic tank
and finally to the pump again. When no more oil can
be added and oil is clear, do the procedure that
follows :
3.
Lift a capacity load to take the weight off of the
steer axle. Turn the steering wheel as rapidly as
possible to remove the air in the steering cylinder
and lines.
4.
Add oil immediately when the valve spool is
activated to replace oil that flows through the
circuit.
NOTICE
Be sure to keep the oil level in the hydraulic tank
above the outlet to the pump. Do not hold steer
wheels against stops for an extended period of
time. This will cause the oil to get hot and
damage the components.
5.
Turn the steer wheels until they have reached the
stop in one direction, then quickly turn the
steering wheel in the opposite direction to the
opposite stop.
6.
This procedure must go on approximately 15 to
20 times, to remove the air from the system. Add
oil as required.
