2. Read the General Precautions for Removing and
Installing Hydraulic System Components at the beginning
of this section.
3. To prevent contamination of hydraulic system during
steering cylinder removal, thoroughly clean exterior of
cylinder and fittings.
NOTE: To ease installation, label the hydraulic hoses to
show their correct position on the steering cylinder.
4. Remove hydraulic hoses from steering cylinder.
5. Remove cotter pins, hex slotted nuts, axle washer
and ball joint spacer from the threaded ends of ball joints
(Fig. 67). Remove steering cylinder with ball joints from
machine.

process to properly orientate fittings. Tighten fittings
(see Hydraulic Fitting Installation in the General Information
section of this chapter).
3. Slide ram end ball joint through hole on steering arm.
Secure with axle washer and hex slotted nut. Slide fixed
end of cylinder through hole on axle. Secure with slotted
hex nut. Torque slotted hex nuts to 100 ft -lbs (135 N -m)
and then continue tightening the nut until hex nut groove
