Thanks Musky,
I have always tensioned the chain first and then put the sliding plate on loosley with the clutch centre going on to position the plate correctly, then tighten it all up. Will check out that speedi sleeve, but I have created a solution that has worked out quite elegantly so if it works, good, if not, speedi sleeve it is!
It will be back together by tonight, and I will post your spindle back to you in the morning mate.
Cheers,
Dave.
