Overhaul Parts List by Engine Model

Crankshafts receive a thorough inspection upon arrival. A serial number is permanently etched into the part. Crankshafts are then degreased, cleaned, and Magnaflux inspected. After passing the Magnaflux inspection, a detailed dimensional evaluation and visual inspection is performed. Crankshafts within repair limits will be repaired on a custom shop order to your specification. If bearing journals are reground the crankshaft is renitrided to restore the wear surface hardness and increase fatigue strength. The crankshaft is then Magnafluxed a second time and the propeller flange is cadmium plated for corrosion protection. Precision digital dynamic balancing is available which improves longevity and results in a smoother running engine. Counterweight assembly on crankshaft is available. A maintenance release is issued for return to service, and custom foam packed for return shipping.
