Help! thread repair main shaft

[Devo]

Trans main shaft is bugured up. Anybody got any ideas on how to clean up the shaft for the drive pulley locknut on a 06 six speed trans? I have cleaned the threads with a angle file and the nut will start then hit a brick wall like its the wrong thread. I don't think the odds of comming up with a left hand thread die is to good.

This trans was shipped in January of 07 and is an Ultima 201-59 Polished Ultima LSD Six Speed Transmission for a softail evo. Surely it doesn't have the 07 and up versus the 91 to 06 Locknut do it?

Thanks,

Sounds to me that the threads are different. When you take a bolt and try to start a nut that is not quite right , it will start and stop dead like you are saying.

pick up a thread file that is the correct threads per inch, long as they aint to bad this could fix it, left or right hand dont make no difference to a thread file, or go to machine shop , sometimes if ya throw em 10 bucks and a deposit they will let you borrow correct left hand die, good luck

Specialx1 is dead on with the thread file - Rt hand Lh hand dont matter, just match the pitch  http://www.amazon.com/dp/B000K1GAI0?smid=A30DGJTMHYAU9C&tag=nextag-auto-delta-20&linkCode=asn  Keep in mind the nut itself may have distorted threads too, causing a hang up.

Yup, agreed on the thread file. That's a great first step.

Another, albeit secondary, tactic is to use an old or "sacrificial" nut as a die of sorts.  This involves hacksawing usually four cuts through the threads (I believe a 45 degree angle is recommended, but you should google all of this!) and then using the nut as a sort of die to chase the threads.

I may google this myself now that you've got me thinking about it.  I'll report back if I find a good tutorial.

Is this the nut that come off or is it a new one? If its new you need to check it with a thread pitch gauge and the shaft to make sure they are the same pitch. If your re-using the old nut how are the threads in it?

PS, nice tutorial on thread files here:

I've never heard of a thread repair file, I think that will do it as the threads are not that bad. Thanks loads.

Call Kromhard in Akron, OH  330-535-7129.  They should be able to fix you up with a die as long as you can give them the thread pitch.

Maybe you may have some luck e-mailing them for thread size. Or ask the above.

The thread repair file I got at NAPA for 12.00 worked like a charm. The guy who invented this thing has my vote for the nobel prize, free beer and eternal flame. Thanks guys for the tip.
