Stub Axle Thread

10 posts in this topic

Does anyone know what the thread is on a series stub axle (presume they are all the same and the same as a defender as the lock nuts are the same part)

Wondering if I can try and use a thread repair file to sort the only very slightly damaged end thread instead of replacing it

 

Thanks

I don't know the thread, but any triangular needle-type file will be fine enough to get in there and clean it up, I would think?

I have tried, but I just can't get the nut to go on without cross threading.

 

Maybe need to have spend a little more time/patience!

I'm relying on my memory, but I did get closely involved some time ago trying to justify the disparity in the 'advice' given about how best to adjust the free play of the wheel bearing.
I was basing my calculations on the pitch of the thread.

Without me moving into the garage to actually measure bits, measure the stub axle thread diameter, then lay a ruler over the undamaged threads and count the threads in 1/2" (say).
then compare the diameter and calculated TPI with a Zeus table (or similar). Look under UNF threads and I think you will find matching numbers.

Sorry I can't be bothered to be more precise.

Regards.

PS. If its only the end threads, and you are struggling with a needle file to do an adequate repair, just file the damaged section flat enough for the nut to pass over the area, with minimal or zero engagement.

Yup, was about to say, if you get too frustrated, just file it off, there should be enough other threads to get it to engage, and do up.

Thanks both. I attacked it with the needle files last night and the nut is now going on a few turns. It is still getting stuck though so I have invested in one of those thread repair files. I really hate throwing something away and spending £70 when there is nothing really much wrong with it

 

There are 18 threads per inch in case anyone is interested!

The right size of die or a die nutwould help solve your problem

And would cost a lot more than a new stub axle!!

I finally sorted it with the thread repair file. Axle now back together!

 

Thanks
