Rear hubs

[John Mason]

Hello all, Following on from my thread on “Re assembling rear brake shoes.” I have given up on trying to fit the brake springs with the hubs in place. Following a lot of reading on how to dismantle and reassemble the hubs I was surprised how easily they came off. The car has been in my possession for over 20 years and have never been touched in that time. Split pin out and a socket on the nut which came undone easily without use of the power bar. I fitted the hub puller and again the outer hub came off the taper easily with only the 12 inch ratchet. No need to strike the bolt in the puller to break the taper on the hub. The inner hub was the same the nut came off easily and was not tight once the lock washer had been straightened. (I did expect this as I had read it only needed to be just nipped up on assembly.). I fitted the break shoes and springs and started to reassemble the inner hub with the rear nut just nipped up and lock washer bent down. Checked the hub which spun easily and then re fitted the outer hub with woodruff key and tightened the nut tight but not fully with a power bar.  Thinking the job almost done I found that the rear of the wheel studs caught on the brake cam stopping rotation of the hub. 
I cannot see anything I have done when reassembling to cause this other than tightening the hub tight onto the taper.
All suggestions gratefully received as to how to rectify this problems 
It goes without saying the hub could be turned freely before strip down.

Yours John Mason.
