Got a good crank and main bearing shells from Mick (good man, many thanks) but the shells don't have any colour coding on them at all that I can find. Fitted them into the crankcases with the crank, using plastiguage and torqued everything up. All the oil clearances are exactly 2 thou but according to the Haynes manual I should be looking for 0.8 - 1.6 thou (20 - 41 microns) with green shells ( crankcases all B's, crank all A's). I'm worried that having the larger oil clearance on the main bearings won't build up enough oil pressure to feed the rockers and although I have been told by an experienced engineer I should be looking for 2 thou, I would obviously want to get it right before re-building the engine. Am I being too pernikety and looking for a problem that does not exist ? Any thoughts would be gratefully received.
