Some advice please. Rebuilding a 1275 A+ I foolishly assembled with main caps on the wrong way around (180 degrees out).
I span the crank only a little - enough to realise my mistake, but upon stripping, one of the bearings has "picked up" a little on one of the crank bearing faces.
i.e. there is bearing material deposited on the crank.
It's maybe 1mm x 2mm and my initial thought is to use a dremel and a small burr or grinding bit to put a dimple on the crank bearing face, making sure all sharp edges are removed and all everything is below flush. My thinking is that there are through holes in this face for oil feed so what I am suggesting isn't too drastic? Of course I'd get some new bearing shells too!
Engine is not intended to be a high power race engine, just a stage 1 weekend cruiser.
I'm sure worst has been done back in the day when minis were cheap and cheerful? I'm on a budget and trying to avoid a £500 crank!
what do you folks think? and I'm ready for the "what are you thinking, only a new crank will do" but really?
