Thrust Bearing

Install main bearing caps (except rear), and tighten cap bolts to specification. See TORQUE SPECIFICATIONS . On 7.4L, apply anaerobic sealant to cap-to-cylinder block mating surfaces. On all engines, Install rear main bearing cap and tighten cap bolts to 10 ft. lbs. (14 N.m). Tap crankshaft rearward then forward to align thrust surfaces. Tighten rear main bearing cap bolts to specification. Measure crankshaft end play at forward thrust surface of rear main bearing cap. See appropriate CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS table under ENGINE SPECIFICATIONS.
