Components & Parts


Hydraulic Component Services is your best source for any new or used hydraulic, pneumatic, and mechanical parts. If you cannot find exactly what you need, don't worry... We rebuild all types and styles of products from many diverse manufacturers.

Hydraulic Component Services can rebuild and supply many different varieties of pumps including hydraulic pumps, pneumatic pumps, gear pumps, vacuum pumps, piston pumps, centrifugal pumps, air over oil pumps, and bane pumps.

We provide service for all Vickers, Cessna, Hydreco, Commercial, Dynapower, Sundstrand, Char Lynn, Ross, Eaton, Continental, Webster, Hydura, Tyrone, H.P.M., Parker Hannifin, Gresen, Dynex, Racine, Denison, Oilgear, and Rexroth hydraulic pumps and motors. Mazak and Mori Seki are two of the many CNC machine manufacturers for whom we rebuild the components.

All wear areas are inspected and then replaced or reclaimed by one of our material transfer processes. The units are checked for proper G.P.M., P.S.I., and torque output, fitted with cap plugs and painted.

For complete service on all sizes and types of hydraulic and pneumatic rams and cylinders contact Hydraulic Component Services. We can provide you with the exact service you need.

All cylinders are disassembled, inspected, and cleaned. Shafts and tubes are checked for taper, concentricity, and chrome plating. Pistons and bearings are checked and, when necessary, are resized to factory tolerances. All cylinders are honed and polished. Packing seals, wipers and piston rings are replaced. All cylinders are pressure oil tested and painted.

We rebuild and supply NFPA tie rod cylinders, ISO cylinders, and custom design cylinders.

Hydraulic Component Services can rebuild or supply new industrial and mobile valves.

We can provide complete valve rebuilding and reconditioning at substantial savings. In our process, valves are completely disassembled, chemically cleaned, and inspected. Worn bodies are precision honed for cleanup and straightness. Pitted and worn spools are pre-ground, chrome plated, finish ground, and are refit back into the valve body to proper tolerances.

All check valves, cylinder port reliefs and the main relief are inspected, reseated, and reset to manufacturer’s specifications. All seals are replaced, and the valve is pressure oil tested. Internal leakage is measured in cubic inch leakage per minute and back pressured for external leakage. The valve body is fitted with cap plugs and painted.

At Hydraulic Component Services we specialize in rebuilding any hydraulic and machine tool index motors. Quality machine tool indexing motors, whether a positioning motor or a hydromechanical revolution positioner, can be brought back to their original high efficiency and reliability quickly, at a fraction of the price and much faster than taking delivery of a new indexing motor.

We specialize in Mazak, Giddings & Lewis, Mori Seiki, Daewoo Puma, Hitachi Seiki, Okuma, Kitamura, Nakamura, Mitsubishi, Hitachi, Okuma Howa, Cincinnati, Toshiba, Toyoda, Enshu, Matsuura, OKK, Hyundai, Bullard, Brother, Miyano, Liebherr, Takisawa, Makino and Mitsui Seiki.

Additionally, we have access to quality machine tool indexing motors which are manufactured by fine Japanese Companies including Nippon, Nachi, Daikin, Orbmark, Trochoid, Gerotor, Kitagawa and NOP.

Whether you need mechanical components rebuilt or supplied as new, Hydraulic Component Services is here for you.

We have extensive knowledge in the re-workings of gear boxes, final drives, torque hubs, planetary gear boxes, spike drivers, shock absorbers, swivels, tailstocks, ball screws, and much more!

With a full service machine shop in-house, we are able to modify and manufacture parts that may hard to find or no longer available in the market.
