I am rebuilding a 951 DI motor after the pistons got damaged due to long standing as well as wrong oil being used. I am also going to rebuilt the crank but want to give my crank builders a higher standard of bearing so I have been looking at SFK bearings. I can locate the standard 6208 bearing with a steel cage but I cannot find one that is pinned to prevent the bearing from spinning, does anyone have a code or suggestions on where I can find these bearings and what to ask for? Also, i am struggling to find the code for the middle bearing on the shaft that is a bit smaller than the other 5 out of the six, anyone have a code/size for me?
