5. Carefully inspect the cylinder internal bore for wear,
scratches, corrosion or other damage. Check the out-
side for damage. Inspect all welds for cracks.
6. Inspect the cylinder ports and threads to be sure they
are free of contamination and that the threads are
clean and not damaged.
7. Check the gland for cracks or damage that could
cause failure.
8. Deep gouges or pitted surfaces require replacement
of parts.
9. Put a light coating of hydraulic fluid on all parts. If
parts are to be left disassembled for a period of time,
such as overnight, they should be covered with a
clean cloth.

Be sure inside of cylinder and all parts are
clean before starting reassembly.
Assemble cylinder carefully to prevent dam-
age to seal lips and O-rings. Seals should be
lubricated with hydraulic oil to assist assem-
bly into cylinder barrel and gland. Heating
seal rings in boiling water before starting
assembly will aid in assembly.
1. Install new O-ring seal on the piston.
2. Install new piston seal over the O-ring seal.
3. Install new gland packing (O-ring) seal on inner end
of gland.
4. Install new rod wiper and rod (U-cup) seal in outer
end of gland.
