MAVAL gear boxes are remanufactured and tested to OEM specifications. Our process includes the inspection and replacement of worm/thrust bearings, bushings, and the inspection of ball guides, balls and the sector shaft. All original snap rings and o-rings are replaced. Each gear box has the MAVAL part number etched into the housing as well as a serial number for traceability. All MAVAL gear boxes are 100% lash calibrated for precision performance.
