Stripped Steering Shaft Threads

[dmaxweb]

When I got the rounded over nut off the steering shaft I discovered the reason. The threads on the shaft are stripped. Not bad but to the point that a new nut will definitely not thread on straight. Can I build it up a bit with welding and re-thread? The worm gear is in great shape.

I think it depends on what your capabilities are and what tools you have. Ideally, you need a lathe to true & re-thread. You do have the option to purchase a new shaft and press off your worm and re-install it on the new shaft.

I had one that was bad, my friend, he was a machinist, drilled and tapped the shaft, threaded in a bolt the same thread as the original, bottomed out the bolt tight, cut off the hex head and chamfered the threads. He then cut the woodruff keyway which was deep enough to go into the new bolt he inserted thus further locking in the repair part. He the drilled for the horn rod. Nice permanent fix.

I've never seen these. How do they work?

I guess it would work about the same as dmaxweb's description.

if the threads are just cross threaded you can run a thread chaser over them and see if you have enough threads to install a new nut, its worth a try

And...I'm guessing the best threads are down below, so find someone with an axle rethreading die, which opens so you can install it below the damage and work up.
If only modern tools are available..."Little Giant" sells neat split dies with an adjustable holder in 5/8-18.

this happen to me i used small triangle file and carefully filed threads.it took many hours but it worked .i used a new nut.

 

[western77]

Try a thread file They work great for something like that.

if you have good threads below, like Bruce mentions

you could take a new nut... hacksaw it in half
install around good lower threads
tack weld it together around the shaft... then thread off
(be careful not to weld to the shaft or melt into the threads of the nut)

hopefully repairing the threads on the way off...

I was able to use a thread file to clean it up. Used some loctite and carefully snugged the nut.
A-OK

Is there enough of a center opening to get reasonable clearance for what has to go through?

All I did was clean up the existing threads on the shaft with the thread file. Did not have any affect the I.D. for the horn rod.

Here is another alternative to keep an eye out for. Multiple diameter re-threader. Open the latch and place over the threads, re-clamp it back together and turn it back off straightening out the threads as you go. The one I have is made by National tool P/N 610. Accommodates 5/8-18, 3/4-20, 3/4-16, 7/8-14, 1-14 and 1 1/8-12.

When mine broke off i kust cut off the end then cut the end off an extra one i hade to the corect sized made shrue they were true put the head light swich rod in and welded it works grate (just Make shure you good at welding if you only make a surface weld after a while it will fetigue and snap while driveing.
