Bearing thickness
Posted: Sat May 14, 2011 4:31 pm
I am rebuilting a 1098 engine which I was given last week. The engine is in very good condition apart from number 2 big end bearings which are scored in the centre. Due to the oil hole blocked which I think is the cause, it has some light scoring on the crankshaft at the same place. I am going to fit new big end bearings and probably get the crankshaft reground. The question I ask is does anyone know what the standard size of big end bearings are ? The bearings that I removed has the bmc part number on them but they don't say STD (for standard) or oversized which I was expecting. Before I think about getting the crankshaft machined I need to know what bearings are fitted to the engine.
