Crankshafts

Crankshafts

Crankshafts receive a thorough inspection upon arrival. A unique 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 work order. If bearing journals are reground the crankshaft must be nitrided to restore wear surface hardness, and increase fatigue strength. A second magnetic particle is done 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. Installation of counterweight assembly onto the crankshaft is available. A complete final inspection is performed on the crankshaft, and an 8130 maintenance release is issued. Lastly the component is oil preserved in a plastic sleeve, and secured in a custom foam protected package for shipping.
