General Motors Sealed Power Standard Steel Backed with Copper-Lead overplate Main Bearing Set 5085M1.(85-90 w/std. length flange brg.) ~Crush Crush refers to the press fit that results from having a small section of the bearing extended above the housing bore when the bearing half is in set in place. Federal-Mogul's performance bearings have additional crush built into the design. This extra material helps to force the outside diameter of the beating against the rod or main bore when the assembly is torqued to specification. By increasing the surface contact between the bearing and it's bore, crush helps to compensate for bore distortion and aids in heat transfer. This is critical because the lubricating oil will break down and cause bearing failure if the area gets too hot.~Chamfer Performance engines often require added crankshaft strength, which mandates special bearings. Racing crankshafts employ a larger diameter fillet radius in the area where the rod journal meets the couterweight. This rounded inside corner increases crankshaft strength, but can interfere with the rod bearing. Many of their performance rod bearings feature a chamfer which provides the side clearance necessary for these cranks. The chamfer is only on the edge of the bearing that is alongside the crankshaft counterweight, thus maintaining as much bearing surface area as possible. Even when using our chamfered bearings, it is advisable to check for adequate clearance in the chamfer area, as different aftermarket crankshaft manufacturers incorporate various fillet radius diameters in their designs. Inadequate clearance in the fillet radius area will cause edge loading on the side of the bearing, resulting in premature wear and eventual failure.~Dowel Holes Several of their racing bearings incorporate a dowel hole. In drag racing applications the utilize aluminum connecting rods, a dowel pin is utilized to positively locate the rod bearing. Without
