Sealed Power Engine Crankshaft Main Bearing Set P/N:6101MA
Sealed 6101MA 20 main bearing set for the 1983-1985 Ford Ranger V6 2.8L, the 1986-1989 Ranger V6 2.9L and other vehicles supports the crankshaft in the engine block as it turns. Its bi-metal alloy has greater seizure resistance than tri-metal material, and the set meets or exceeds OEM specifications.
A knocking sound from the lower engine, low oil pressure or metal particles in the oil can mean the main bearings are worn, though the oil pump or a damaged crankshaft journal can be behind the same signs. The 1986-1989 Ford Ranger V6 2.9L takes one set.
The 1984-1985 Ford Bronco II V6 2.8L, the 1986-1989 Bronco II V6 2.9L and the 1988-1989 Merkur Scorpio V6 2.9L all fit this set, and so do many other vehicles. Open the "Vehicles it fits" section to check your exact model and engine.
