Lift and Bucket Cylinder Dissemble

Following is an outline procedure for disassembling and reassembling cylinders

1.Hold cylinder tube (13) stationary and pull wire ring (14) out through slot.

2.Pull shaft (1), with all assembled parts, out of cylinder tube (13).

Note: Resistance will be felt until piston seal (8) slides over wire retaining ring groove.

3.Remove elastic locknut (12) from end of shaft and slide cylinder piston (9) and cylinder head (5) off shaft.

4.Remove piston wear ring (8), piston seal (11), and o-ring (10) from outside grooves on piston(9).

5.Remove wiper seal (2), rod seal (3) and wear ring (4) from inside of cylinder head (4) and o-ring (7) with backup washer (6) from groove on outside of head.

6.Clean all parts including cylinder tube, in a suitable cleaning solvent, then use air pressure to blow any dirt or excess solvent from all parts.

7.Examine all parts for wear or damage and replace, if necessary.

Lift and Bucket Cylinder Reassembly

Note: Be careful not to damage seals and o-rings on edges or holes in cylinder tube. Inspect and remove burrs and sharp edges if necessary before reassembly.

1.Place rod seal (3) into groove inside cylinder head.

Note: Lips of seal (3) must be face inward and seal must be firmly seated in groove.

2.Install wiper seal (2) with lip of seal facing out and flush with top of cylinder head (5). Install wear ring (4) inside other end of head (5).

3.Place o-ring (7) with back-up washer (6) in groove on outside of head. Back-up washer must be on rod side.

4.Remove sharp edges on outer edge of the threaded end of shaft (1). Lubricate wiper seal (2) and rod seal

(3) in head and carefully slide head onto shaft.

5.Place o-ring (10), piston seal (11) and piston wear ring (8) in grooves on outside of piston (9). Note: For easier installation, place piston seal (11) in 120°F water to warm seal.

6.Slide piston (9) onto threaded end of shaft and install lock nut (12). Tighten lock nut to 100 lbs.

7.Lubricate piston wear ring (8) and piston seal (11) on piston, o-ring (7) and backup washer (6) on head and inside of cylinder tube (13), then carefully slide piston and head into cylinder tube (13).

8.Insert wire retaining ring (14) into slot in cylinder tube (13). Apply pressure to wire ring to thread it into groove while turning cylinder head.
