Axle housing repair apparatus and method for replacing a vehicle axle tube assembly

Details

Inventors: Hart, Arthur J.;
Assignee:
Primary Examiner: Eley; Timothy V.
Assistant Examiner:
Attorney, Agent or Firm: Rosenbaum & Schwartz

The present invention is an apparatus used to replace an axle housing for a light duty truck. The device consists of a frame which includes supports to hold axle housing tube assemblies and a differential mechanism housing. The apparatus includes a push rod attached to a hydraulic or mechanical press or ram. A collar is attached to the push rod. The push rod extends through the first axle tube assembly and the differential housing and the collar is placed against the circumference of the second axle tube assembly. In operation the ram is activated and the second axle tube assembly is forced apart from the differential housing so that a replacement axle tube assembly can be attached to the differential housing.

DETAILED DESCRIPTION The present invention is an apparatus used to remove the defective axle housing tube assembly and allow a replacement to be attached to the differential housing.
The present invention supports both the tube assemblies and the differential housing.
In use, a push rod is placed through the first axle housing tube and the differential housing.
A collar is then attached to the push rod.
The collar is sized to match the circumference and inner bore diameter of the second axle housing tube.
A hydraulic ram is then used to force the axle housing tube to separate from the differential housing so that a replacement axle housing tube can be installed.
It is an object of the present invention to provide an apparatus to allow for the removal of a damaged or defective axle housing tube from a differential housing to allow for the damaged or defective axle housing to be replaced.
It is a further object of the invention to allow for the safe and accurate repair and replacement of a damaged or defective axle housing.
It is still a further object of the invention to provide an apparatus that also allows for the repair of a bent or warped axle housing.
It is yet a further object of the invention to provide for the proper alignment of an axle housing relative to a differential housing.
