Every new repair we develop helps you keep engine overhaul or repair expenses at a minimum.

  • Tapit Bodies MRO

    Tappet bodies undergo a complete remanufacturing process on the same equipment utilized for new manufacture. Tappets are degreased and ultrasonically cleaned. The spherical radius is precision ground on the latest state of the art CNC machines. Each batch is then heat-treated with a process that forms a wear-resistant coating.

  • Camshafts MRO

    A complete receiving inspection is performed on each camshaft. The camshaft is degreased, cleaned, magnetic particle and dimensionally inspected. Repairs are performed, including regrinding lobes to the original profile and taper. The surface finish is restored by Parkerizing where required

  • Crankshafts MRO

    Crankshafts receive a thorough inspection upon arrival. A serial number is permanently etched onto the part. Crankshafts are then disassembled, cleaned, and Magnetic Particle inspected. If no cracks or metallurgical flaws are found, a detailed dimensional evaluation and visual inspection is performed. Crankshafts found within repair limits will be repaired on a custom shop order to your specification
