Reference Information

Differential Case, Nodular Iron, 9 in. Ford, 3.250 in. Carrier Bearing Size, Each

Strange 9 in. nodular iron cases have steel bearing caps with socket head cap screws and machined adjusting nuts. The cases use D-4512 nodular iron--eight percent stronger than OEM nodular iron--and have extra material around the pinion pilot bearing area to prevent cracking. The bolt holes are deep-tapped and cast with extra material around their diameters. Bearing bores and reinforcing ribs are also cast with additional material for strength, and the stud holes are spot-faced to prevent leaks and mounting surface damage.
