5. When removing the piston, first move it toward the-
gland end of the body just far enough to permit
removing the o-ring seal. Then move the piston in
the opposite direction just far enough to permit
removing the o-ring seal from the other end. Now
slide the piston out from the gland end of the body.
Inspection and Reconditioning.
Clean and wash all parts thoroughly in solvent or kerosene. Handle the parts separately and carefully to avoid damaging
the finished surfaces. Wear of parts such as piston, reaction rings and valve body is negligible as these parts operate in
circulating oil. It is impractical for a field service shop to attempt to measure wear. Therefore a careful visual inspection of
all parts is most important.
Examine the surfaces of the piston and the bore of the body for scoring or damage that may have been caused by foreign
matter in the fluid. Parts that are badly scored and scratched should be replaced. Light scratches can be removed by
polishing with fine crocus cloth. Do not "round-off" or chamfer the port edges of the piston or body. These edges should
remain sharp to insure proper sealing. If they are broken the result would be excessive leakage and reduced hydraulic
power.
O-ring seals should be examined carefully for damage. If surface is rough or cut it should be replaced.
REASSEMBLY.
Reassemble is opposite of disassemble.
