2. Mount the steering cylinder securely in a vise by clamping on the mounting
brackets.
3. Remove the collar set screws and use a strap, chain, or spanner wrench to
remove the collars from each end of the barrel.
4. Use a twisting motion to carefully pull the rod, piston, and head assemblies
from the barrel.
5. Carefully push the remaining head assembly from the barrel.
6. Remove and discard the roll pin that secures the rods together. Separate
(unscrew) the rods and remove the spacers and the piston assembly.
7. Remove and discard the seals, O-rings, and wear rings from the piston
and heads.
Use eye protection such as goggles when using compressed air.
1. Wash all the cylinder components in clean solvent and dry them with
compressed air.
2. Inspect the internal surface of the barrel for deep scratches, out-of-roundness,
and bending.
3. Inspect the head, rods, and piston for excessive pitting, scoring, and wear.
4. Check the re-phasing valve in the piston that exists to allow synchronization
of the front and rear steering cylinders. The poppet valves should not be
stuck in piston.
5. Replace the cylinder if the internal components are worn or damaged.
Avoid pinching, cutting, or otherwise damaging the O-rings, seals,
and the wear ring during assembly. Lubricate the O-rings, seals, and
the wear ring with clean hydraulic fluid prior to assembly.
1. Use a new seal kit and replace all the seals, O-rings, and the wear ring on
the piston and heads.
2. Carefully fit the piston assembly over the male rod.
3. Thread the rods together until the roll pin holes in the rods align and install
the roll pin.
When you clamp the steering cylinder in a vise, clamp against the
mounting brackets only to prevent damage. Do not clamp the vise
onto the barrel or rod.
