Constructed of metal, this is a non-sealed design, which means it can be greased for ongoing lubrication rather than being a sealed, grease-and-forget unit. The bearing measures 4 x 4 x 2 inches overall with a 2 inch outside diameter, and weighs 1.3 pounds.\u003c\/p\u003e\u003cp\u003eThis bearing is a direct replacement for OMC part number 3853807 and is intended for OMC\/Volvo engines in the 3.0L, 4.3L, 5.0L, 5.7L, and 7.4L range (1994-1998), the 5.8L (1994-1996), and the 8.2L (1998).
