C.A.T. h-beam rods and forged cranks are strong enough pieces, but their quality control department is somewhat suspect. Rods will sometimes be out of round or tapered in the big end bore, cranks may be out of round or tapered on the mains and rods, or just out of tolerance on size. Nothing wrong with the strength-- just requires a tune-up by your local machine shop. Maybe the seller will agree to let you have the crank inspected by a nearby shop before you buy? If it passes then you have a deal.
