Crankshafts
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. If bearing journals are reground the crankshaft must be nitrided to restore wear surface hardness and increase fatigue strength. A second Magnetic Particle inspection 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. An 8130 maintenance release is issued and the unit is custom foam packaged for shipping.
