With facilities capable of handling crankshafts up to 11,000mm in length and 510mm in diameter, LC&M offers precision grinding, polishing, and specialised repairs. Upon receiving a crankshaft, the team performs thorough inspections, including ultrasonic and magnetic particle testing, dimensional checks, and hardness surveys, to determine the best salvage approach. Additional restoration options, like chrome plating, are available through approved subcontractors. All work is closely coordinated with the customer, and LC&M can also meet third-party standards, such as LR, ABS, and DNV, as needed.
