Sealed Power Engine Crankshaft Main Bearing Set P/N:4664M
Sealed Power 4664M 10 main bearing set for the 1967-1969 Buick Electra V8 7.0L, the 1970-1976 Electra V8 7.5L and other vehicles supports the crankshaft as it spins in the engine block. These Sealed Power main bearings sit between the crankshaft journals and the block, where they carry the rotating load.
Worn crankshaft main bearings can show up as a knock from the lower engine or a low oil pressure reading. Before you replace the bearings, rule out other sources of that noise or reading, such as an accessory or the oil pressure sender, so the engine is not opened up for nothing.
The 1967-1969 Buick Electra V8 7.0L, the 1970-1976 Electra V8 7.5L, the 1967-1969 Buick Riviera V8 7.0L, the 1970-1976 Riviera V8 7.5L and the 1970-1976 Buick Estate Wagon V8 7.5L take this set, and so do many other vehicles. If your Buick is not named here, look up its year and engine in the "Vehicles it fits" section. The set meets or exceeds OEM specifications.
