Bearing Selection: Notes
WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 2003 Jaguar XJR, 2003 Jaguar XJ8, 2003 Jaguar XJ, 2002 Jaguar XJR, and 2002 Jaguar XJ8. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Journals are numbered from timing chain side of engine to flywheel side of engine.
Main and rod bearing selection is made by using crankshaft and block codes. See Figure. First 5 digits of the crankshaft code are use to determine crankshaft main bearing journal diameters. Last 4 digits of the crankshaft code are use to determine crankshaft rod bearing journal diameters. First 8 digits of the block code are used to determine cylinder bore diameter. Last 5 digits of block code are use to determine block main bearing journal diameter.
