Disassembly (Fig. 68) 1. Pump oil out of cylinder into a drain pan by SLOWLY moving rod and piston in and out of cylinder bore. Plug ports and clean outside of cylinder. IMPORTANT: To prevent damage when clamping cylinder in a vise, clamp only on pivotal ends. Use of a vise with soft jaws is recommended. 2. Mount cylinder in a vise so rod end of cylinder is tilted up slightly. Do not close vise so firmly that cylinder tube could become distorted. 3. Loosen head from tube: A. Use a spanner wrench to rotate head clockwise until the edge of the retaining ring appears in the tube opening. B. Insert a screwdriver under the beveled edge of the retaining ring to start the retaining ring through the opening. C. Rotate the head counter--clockwise to remove retaining ring from tube and head. 4. Grasp end of piston rod and use a twisting and pulling motion to carefully extract piston, piston rod and head from cylinder tube. IMPORTANT: Do not clamp vise jaws against piston rod surface; the piston rod will become damaged. 5. Securely mount piston, piston rod and head into vise and remove piston. Remove head from rod. 6. Remove and discard all seals and O--rings from head and piston. 7. Wash parts in clean solvent. Dry parts with compressed air. Do not wipe parts dry with paper towels or cloth. Lint in a hydraulic system will cause damage. 8. Carefully inspect internal surface of barrel for damage (deep scratches, out--of--round, etc.). Replace entire cylinder if barrel is damaged. Inspect rod and piston for evidence of excessive scoring, pitting or wear. Replace any damaged parts. Assembly (Fig. 68) 1. Use a complete repair kit when rebuilding the cylinder. Put a coating of clean hydraulic oil on all new seals and O--rings. 2. Install new O--rings and seals to the piston and head. 3. Lubricate shaft with clean hydraulic oil. Slide head onto shaft. Install and tighten head. Torque head from 45 to 55 ft -lb (62 to 74 N -m). 4. Put a coating of clean hydraulic oil on all cylinder parts to ease assembly. 5. Slide rod assembly into cylinder tube. 6. Mount steering cylinder in a vise with soft jaws. Secure head in barrel: A. Align retaining ring hole in the head with the access slot in the tube. B. Insert the retaining ring hook into the hole and rotate head clockwise until the retaining ring is completely pulled into the tube and the ring ends are covered. C. Apply silicone sealer to tube access slot. Hydraulic System Groundsmaster 4100--D Page 4 - 101 Hydraulic System
