Disassembly (Fig. 60)
1.Remove oil from the cylinder into a drain pan by slowly pumping the cylinder shaft (6). Plug both ports and clean the outside of the lift cylinder.
IMPORTANT: Prevent damage when clamping the lift cylinder into a vise; clamp on the pivot only. Do not close vise enough to distort barrel (11).
2.Mount lift cylinder in a vise so that the shaft (6) end tilts up slightly. Remove and discard dust seal (12).
3.Rotate head (3) with a spanner wrench and remove retaining ring (1) as shown in Figure 61.
4.Grasp end of shaft (6); extract shaft, head (3), and piston (8) by carefully twisting and pulling on the shaft.
IMPORTANT: Do not clamp vise jaws against shaft
(6)surface. Protect shaft surface before mounting in the vise.
5.Mount shaft (6) securely in a vise by clamping vise on the flats of the shaft. Remove locknut (10) and piston
(8) from the shaft. Slide head (3) off the shaft.
