Disassembly (Fig. 52)<br />
1. Remove oil from the steering cylinder into a drain pan<br />
by slowly pumping the cylinder shaft. Plug both ports<br />
and clean the outside of the cylinder.<br />
IMPORTANT: Prevent damage when clamping the<br />
hydraulic cylinder into a vise. Do not close vise<br />
enough to distort the barrel.<br />
2. Mount end of steering cylinder in a vise. Remove retaining<br />
ring that secures head into barrel.<br />
3. Remove plugs from ports. Extract shaft, head, and<br />
piston by carefully twisting and pulling on the shaft.<br />
IMPORTANT: Do not clamp vise jaws against the<br />
shaft surface. <strong>Pro</strong>tect shaft surface before mounting<br />
in a vice.<br />
4. Mount shaft securely in a vise by clamping on the end<br />
of the shaft. Remove lock nut and piston from the shaft.<br />
Slide head off the shaft.<br />
5. Remove Uni–ring and o–ring from the piston.<br />
6. Remove o–ring, back–up ring, rod seal, and dust<br />
seal from the head.<br />
Reassembly (Fig. 52)<br />
1. Make sure all parts are clean before reassembly.<br />
2. Coat new o–rings, Uni–ring, rod seal, and back–up<br />
ring with with clean hydraulic oil.<br />
A. Install Uni–ring and o–ring to the piston.<br />
B. Install o–ring, back–up ring, rod seal, and dust<br />
seal to the head.<br />
IMPORTANT: Do not clamp vise jaws against the<br />
shaft surface. <strong>Pro</strong>tect shaft surface before mounting<br />
in a vice.<br />
3. Mount shaft securely in a vise by clamping on the end<br />
of the shaft.<br />
A. Coat shaft with a light coat of clean hydraulic oil.<br />
B. Slide head assembly onto the shaft. Install piston<br />
and lock nut onto the shaft. Torque lock nut 40 ft–lb<br />
(54 N–m) to secure assembly.<br />
C. Remove shaft from the vise.<br />
IMPORTANT: Prevent damage when clamping the<br />
hydraulic cylinder into a vise. Do not close vise<br />
enough to distort the barrel.<br />
4. Mount end of the barrel in a vise.<br />
5. Coat all internal parts with a light coat of clean hydraulic<br />
oil. Slide piston, shaft, and head assembly into<br />
the barrel being careful not to damage the seals.<br />
6. Secure head into the barrel with retaining ring.<br />
