[QUOTE="jim burgess, post: 178746, member: 1978"] I didn't weld the wheel on, honest, I'm just checking the thing over for a club member. I can see how welding could work, I can understand why it was done. But my very limited experience with welding gear leaves me feeling that it is a process likely to create as many problems as it solves, especially as in this case it is a short weld on the back of the wheel in one position only. Bob Dunn once showed me a primary case for a twin that looked like a banana after an inexpert welding job. Maybe 25mm out of alignment from front to rear, his job was to make it all be straight again... ho hum... In this case the shaft and wheel will fit on the slightly worn spindle, but a new spindle will not enter so I suspect the actual shaft may be out of true, however close inspection also indicates the fitment of the bearing with a blunt instrument and kinetic energy... Looking at the contents of the timing case does leave me wondering: Why are the spindles so damn skinny? Why don't they screw into the case? Why not have much bigger bearing surfaces for all components? Why no needle rollers? It is hard to imagine the immediate post war era and the restrictions that had to be worked to at that time, but I can't help seeing the timing case as a group of missed opportunities. But then we are 70 years down range of the launch of the vehicles and I guess nobody thought we would still be working on them. Many thanks to you all! Jim [/QUOTE]
