Aston Service Dorset: Crankshaft Assembly

On early LB6B (2.6 litre) engines the connecting rod big end bearings are white metalled direct.

From engine number LB6B/571 and VB6B/1034 onwards and all 3 litre power units, big end bearings are of the "thin wall shell" type in lead bronze, steel backed. All small end bearings are bush type of phosphor bronze.


Below is a table of tolerances for big end and main journal bearings to assist in working out which replacement bearings you will require:
