Main Bearing Set for the Rover 3.5-litre V8 petrol engine. These are the replaceable shell bearings that carry the crankshaft in the cylinder block, locating each main journal and providing the running surface on which the crankshaft turns.

Supplied in standard size, for a crankshaft running at its original (unmachined) main journal diameters. Renewed during an engine rebuild or when bearing wear, low oil pressure or knock is found.
