Lift Cylinder Repair – No. 1 (Center) (Fig. 34)

Figure 34

IMPORTANT: To prevent damage when clamping the cylinder barrel in a vise, clamp only on the pivot end. Do not clamp the vise jaws against the smooth shaft surface. Protect the shaft surface before mounting in the vise.

1.After removing the cylinder, pump the oil out of the cylinder into a drain pan by SLOWLY moving the cylin- der’s piston in and out of the cylinder bore.

2.Plug the ports and clean the outside of the cylinder.

3.Mount the cylinder in a vise so the shaft end of the cylinder is tilted up slightly. Do not close the vise so firmly that the barrel could become distorted.

4.Remove the retaining ring (Item 10). Grasp clevis end of shaft (Item 11) and use a twisting and pulling motion to carefully extract piston (Item 4), shaft (Item 11), and head (Item 8) from the barrel (Item 1).

5.Securely mount the shaft (Item 11) in a vise and remove the lock nut (Item 2) from the piston end of the shaft. Remove the piston (Item 4). Slide the head (Item 8) off of the shaft.

6.Remove and discard all seals and back-up rings (Items 3, 5, 6, 7, 9).

7.Wash the parts in a safe solvent. Dry the parts with compressed air. DO NOT wipe them dry with a cloth or paper as lint and dirt may remain.

8.Inspect the internal surface of the barrel (Item 1) for damage (deep scratches, out-of-round, etc.). Inspect the head (Item 8), shaft (Item 11) and piston (Item 4) for evidence of excessive scoring, pitting, or wear. Replace any defective parts.

9.Put a light coating of hydraulic oil on all new seals and back-up washers. Install the new seals and back-up washers (Items 3, 5, 6, 7, 9). Install the head (Item 8) onto the shaft (Item 11). Install the piston (Item 4) onto the shaft and tighten the lock nut (Item 2).

10.Put a light coating of hydraulic oil on all cylinder parts to ease assembly. Slide the shaft assembly and head into the barrel. Install the retaining ring (Item 10) to secure the assembly in the barrel.
