Big Or Small, We've Got You Covered

Radwell provides quality repair services for hydraulic components, including motors, pumps, actuators, valves, servo valves, and cylinders.

All repairable hydraulic units received into our facilities are disassembled, cleaned, and evaluated. When the evaluation is complete one of our Customer Service Representatives will provide you with a repair quote. Once you approve the repair, our highly-trained technicians will begin the repair process. After completion, the hydraulic unit will be placed under a full load test to ensure that it meets or exceeds the OEM standards before shipping the unit back to you.

Popular Hydraulic Repairs

Hydraulic Pump Repair

Piston Pump

All piston pumps parts are inspected and remanufactured back to OEM specifications or replaced as needed.
All bores are inspected to ensure they meet specifications
Valve plates are inspected and lapped
The metering and timing notch is checked and cut if found out of tolerance
The cylinder block is lapped and treated to increase meantime between failures.
The piston shoe subassembly diameter is matched with cylinder bore diameters to match the manufacturers' specs.
The Piston shoe height is checked using a micrometer to ensure the repair is within tolerance.
All pumps are tested under full load, flowrates, pressure, and temperature are recorded on output and case drain.
Test reports are provided with each repair.

Hydraulic Pump Repair

Vane Pump

The vane slots are checked to guarantee vanes will be stable and free moving.
The vane set is checked with a micrometer for proper thickness.
The set is refinished and checked as a set.
All vane tip surfaces are returned to original condition.
All cam ring inside contours are refinished.
Using our lapping machine all plates are precision lapped
All lubrication grooves, depth of metering, timing notches and are checked and recut to tolerance.
Every plate is surface treated to allow the microscopic film of oil that must be present between the plate and the rotor.
All pumps are tested under full load, flowrates, pressure, and temperature are recorded on output and case drain.

Hydraulic Motor Repair

Piston Motor

The rotor & pistons checked and repaired as needed.
The distributor checked and remanufactured as needed.
The gaskets, seals, and o-rings are replaced with new parts.
All bearings are replaced to ensure smooth operation and a long lifecycle.
The distributor casing is lapped or honed.
Motors are load tested on our hydraulic test bench and under load on our hydraulic dynamometer.

Hydraulic Motor Repair

Vane Motor

The timing notches, lubrication grooves, depth of metering, and seal grooves are checked and repaired as needed.
The plate surface is treated to ensure high torque capability, low leakage, and longer lifecycle.
Every cam ring inside contour is refinished using a series of polishing wheels that follow the contour to smooth out even the slightest surface imperfections without changing the slope and dwell angles.
After the surface is polished a severe duty proprietary coating is applied to the inside ring contour to reduce ring wear and lengthen its service life.
All vanes are checked with a micrometer for thickness.
Every motor is assembled using new springs and rotors that ensure the proper load on the vanes as well as the proper vane slot dimensions.
Motors are tested under load on our hydraulic dynamometer.

Hydraulic Test
Bench

Radwell Hydraulic Test Bench (nicknamed The Beast) was designed and built in house using state of the art technology. It is capable of testing most manufacturers pumps, motors, cylinders, and valves. The Beast is PLC controlled allowing the operator to run past specific automated testing while remaining safe. The Beast features over 30 sensors measuring all aspects of hydraulic performance.

The Beast features a hydrostatic transmission which allows the operator to test pumps and motors under load. While under test the PLC is gathering and recording performance data. At the end of the test a performance graph is printed out.
