Receiving the first of 32 Bucher Hydraulics, gear hydraulic motors for inspection to determine the level of rebuild required.

Tear-down and evaluation of all internal parts. All Parts were measured, fits and finishes checked for visible damage.

Many internal parts were dye checked for wear and or cracks. A series of valve bushing were found to have cracks and light scoring.

The gear sections on several motors were found to have severe damage on the section face as well as damage to the gears and gear rings.

This gear and gear ring were so badly damaged we had to scrap the motor. The severity of wear from motor to motor was surprising.

On some motors the shafts had to be replaced due to wear in the coupling area. Some Key ways in the gears were sheared.

After refurbishment each motor was tested for a 6 hour period. Each shaft was locked up with tooling for 15 min. to measure internal leakage.

Four of the motors were bi-rotational and they were tested for 1.5 hrs. in each direction. These motors also had extra valves to test.

All of the motors were fully detailed & painted to "like-new" condition. Each motor weighed over 900 pounds which made handling difficult.
