Removing the Steering Cylinder (continued)
CAUTION
Before opening the hydraulic system, operate all the hydraulic
controls to release system pressure and avoid injury from the
pressurized hydraulic fluid; refer to
Releasing Pressure from the
Hydraulic System (page 6–8) .
3. For assembly purposes, label all the hydraulic hoses and tubes that are
connected to the fittings on the steering cylinder.
4. Clean the hydraulic hose ends before you disconnect the hoses from the
steering cylinder.
5. Disconnect the hydraulic hoses from the steering cylinder.
6. Install caps or plugs on the disconnected hoses and fittings to prevent
contamination.
7. Remove the 2 jam nuts (item 11 in Figure 188 ) that secure the steering
cylinder to the axle. Remove the cotter pin (item 13 in Figure 188 ) and slotted
hex nut that secure the steering cylinder to the right drag link.
8. Separate the steering cylinder ball joints from the axle assembly. Remove
the steering cylinder from the machine.

9. If necessary, remove the ball joint from the steering cylinder barrel and
shaft. If the ball joint is to be removed from the cylinder shaft, fully retract
the cylinder shaft and measure the ball joints center to center length for easy
installation of the ball joint into the cylinder shaft (
Figure 189 ).
10. If the hydraulic fittings are to be removed from the steering cylinder, mark
the fitting orientation for assembly purposes. Remove the fittings from the
steering cylinder and discard the O-rings from the fittings.
Installing the Steering Cylinder
1. If the hydraulic fittings were removed from the steering cylinder, lubricate
new O-rings with clean hydraulic fluid, position the O-rings to the fittings,
and install the fittings into the steering cylinder ports; refer to
Installing the
Hydraulic Fittings (SAE Straight Thread O-Ring Fitting into the Component
Port) (page 6–13)
. Ensure that the fittings are orientated correctly.
2. If removed, press the ball joint (item 9 in Figure 188 ) into the barrel and
secure the ball joint with the retaining ring. Ensure that the retaining ring is
fully seated in groove in the steering cylinder barrel.
3. If the ball joint (item 18 in Figure 188 ) was removed from the cylinder shaft,
fully retract the cylinder shaft and thread the ball joint into the shaft so that
