Abstract

See full text

A hydraulic pump can be remanufactured to save the investment in its components that are not seriously worn or failed. Some of the worn components, such as the pump barrel and yoke, can be salvaged by replacing or rebuilding the worn features. In particular, a worn internal spline on the pump barrel can be replaced by a spline insert that is threaded to the pump barrel and includes a new internal spline. A worn actuation tab on a yoke for contacting an actuating piston can be replaced by adding a new tab wear button.
