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