Re: 47 Steering Column disassembly help needed.

I had about the same problem with my 2150 and after a whole life restoring old British motorcycles I do not like bearings with loose balls which are plentiful on most of them. So I took some measurements. My steering shaft is 7/8 and the tube around it is 1 7/16. The bearing is 7/16 thick so I needed a bearing 7/8 X 1 7/16 X 7/16 which equals 22,5 X 36,6 X 11 millimeters. I found a needlebearing of 25 X 37 X 17 millimeters called RNA 4904. I did some grinding in the tube to press in the outer race and made a stepped sleeve on the shaft to locate the needles which run directly on the sleeve, no inner race. Now when I want to remove the outer tube from the steering shaft the outer race stays in the tube, the needles stay on the shaft but can be lifted off and no loose balls on the floor. So far it works perfect but have not yet installed the mechanism for direction indicators or horn. You can see it used onyoutube.com/watch?v=nsA2H-3Azes
