Example applications
BMW E46 330d; E60/E61 525d, 530d and 535d; E63/E64 635d; E65/E66 730d; E83 X3 3.0d/3.0sd; E53/E70 X5 3.0d/3.0sd; and E71 X6 xDrive30d/xDrive35d with an M57 engine.
Two different main-bearing families are listed for M57 applications, including H1238/7 and H023/7. Do not select the set solely by the M57 designation or vehicle model. Verify the correct version using the engine code and VIN, and compare the numbers and construction of the removed bearings before ordering.
STD denotes standard size. The crankshaft journals and bearing clearances must be measured during the rebuild; this set does not compensate for a worn or machined crankshaft.
