[QUOTE="rapcom, post: 34516, member: 191"] Gentlemen, May I have your expert opinions as to how close a fit should be the ET77 Mainshaft Oil Scroll (called Main Bearing Distance Piece in the Parts List) in the ET19 Main Bearing Spacer ? I have two used ones available, one 1.3580", the other 1.3585", but both are slightly sloppy in the ET19. Given that ET77 plays a part in oil control, should the fit be as close as possible but still allowing free rotation, or will a used one suffice? How quickly will a new one wear down to the same dimension as the ones I have already? Would too good a fit reduce the oil supply to the outer main bearing to ill effect? Does anyone have a new one handy that they could measure? Many thanks. Rapcom [/QUOTE]
