4. Loosen and remove 6 each socket head cap screws retaining cylinder head
to hydraulic cylinder. The cylinder head and its O-ring can be removed. The
proximity switch mounting flats provide a small lip for loosening the cylinder
head.
5. To remove the hydraulic piston from the hydraulic cylinder, remove both
cylinder heads. The piston must be driven from the cylinder bore due to the
seal squeeze and friction. Use a plastic head hammer to avoid striking the
assembly with a metal object. See Section 7.3.7 for servicing the hydraulic
piston.
6. Reassemble the hydraulic cylinder by reversing the above steps.
