RIMCO, and perhaps some other good shops, will cut a case only as much as it needs to clean up, and then modify (widen) an undersize bearing to fit. I believe they do this in .004" increments. When they do this they stamp a 5 digit number on the face of the case just outside of the place where the flywheel seal presses in. The first 2 digits of that number is the amount of oversize, in thousandths of an inch, that they cut the bearing bores, and the last 3 digits are the case thrust width in thousandths of an inch. Look at your case and see if you find a number that matches up to what you measure. If so, you can send RIMCO that number and the journal size of your crank, and they can send you a bearing set that will work for you. You could also do this yourself on a lathe, but you'll need to make some tooling and it's rather precise work. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
