"Refreshing" threads on Sierra rear hubs
Has anybody redone the thread (threads) on Sierra rear hubs ? They are slightly bent on my hubs. I was thinking about recutting them but I don't
know the thread (only that they are 41mm and handed). Can anybody hel with that ?
I understand though that dies in that size might be difficult bar impossible to find, in particular in Poland so I am open to alternatives. Has
anybody done it in a different way ? Maybe using old nuts and forcing them through the bent section of thread ? Any advice ?
Thanks and regards,
Michal

i'd use a needle file and reshape the bent bits of thread.
failing that' i'd source new halfshafts.

possibly simpler/quicker/cheaper to source replacement parts IMHO.

You could ty one of these, far quicker than a needle file.

i have done this and extended threads using a file; but depends how mangked the threads are.
a file is removing metal so is obvisouls not ideal.
if you have a nut or two, making a cut down one side, open it up a bit, windng it on then hammer it closed to reform the threads may work better.
since just running a nut over bad threads ruins the nuts and then spoils the thread.
finish off by running a nut down the reformed threads.

Sourcing can be an issue - it's not so easy to find lobro shafts in Poland and getting them from UK will cost me an arm and a leg.
I'll go and see a workshop nearby, they work on old Leyland trucks so there is a chance that they have some strange (for us) dies. If it fails,
I'll try the file.
Thanks for all your advice though

PS. Btw. any info on threads on these ?

The Frost description of the tool isn't quite correct
Thread repairing tools aren't files, the idea is initially you roll the tool on the thread to reset the pitch of the damaged threads rather
than file the lumps off.
If that dosen't work then you can try using it as a file.

Do you know someone with a lathe that knows how to use it ? Would have thought that would be the best way to clean up the threads.
