1. Slowly pump the cylinder shaft to remove the hydraulic fluid from the steering
cylinder into a drain pan. Plug both the ports and clean the outer surface of
the cylinder.
When you clamp the steering cylinder in a vise, clamp the pivot end
only to prevent damage. Do not close the vise on the barrel.
2. Mount the steering cylinder securely in a vise by clamping on the pivot end
so that the shaft end tilts up slightly. Use a vise equipped with soft jaws.
3. Use a spanner wrench to loosen and remove the internal collar (item 5 in
Figure 99) from the barrel.
4. Hold the end of the shaft and use a twisting and pulling motion to carefully
extract the shaft, internal collar, head, and piston from the barrel.
