Hello all,
A quick update on this thread:
First thanks for the info on the shims. As you correctly pointed out the shims were not behind the primary and that is why it cracked at the front. I purposely removed the shims as the primary inner was bowed and I thought it would un bow if I removed the shims. Then ultimately of course I gave up anyway and went with the belt drive. No worries though as I have another primary casing.
My biggest worry right now is the gearbox main shaft and clutch wobble issue. So I took everything off and set up my dial gauge. As you know it is threaded on the end of the mainshaft and of course very difficult to measure with a dial gauge. Based upon checking many times I have come up with the conclusion that the mainshaft could be bent by 5 thou. I am going to check it again today and try and put a sleeve over the threads.
So I called Quaife and they told me Mick Hemmings is the outlet for their parts. I called him and he said the clutches do wobble a bit due to having that ball bearing in the clutch. I was told Quaife do not make standard gearbox parts and he told me to get a Norton one and it will be straight.
So my plan is to order a new stock mainshaft, fit that to G/B and have another go at this. I will shoot another movie with the new mainshaft and we will see if the clutch still wobbles. The problem with this kind of thing is that if I dont change it I will be riding my bike like a nut in the mountains as I do and I will be thinking about my clutch wobbling,
All for now Jerry
