It's not an early crankcase. Sorry I gave you the wrong number. I'll take of the small front timing gear in a minute and the front bearing outer retaining plate. If the outer bearings have been spinning in the case it might have worn the case, which would explain the rumbling noise. I hope it isn't. If it is, hopefully if I clean it thoroughly I can loctite the bearings in place or a slight film of JB Weld, then fit the spacer rings to take up the end float. I'll post on here soon, when I've removed the small gear etc.
