Wallowed out on front axle extension.

Postby tractorpoor » Fri Apr 23, 2021 4:42 pm

Looking for suggestions. Was thinking of welding the hole closed and redrilling. Not sure that will hold though. What do y’all think?

The PO had welded the extension to the axle. I spent most of the afternoon breaking the weld and remoythe extension.

That hole is not intended to hold the axle in place, it is to index it at the extension location and be a safety item in case the clamp comes loose. Building it up and redrilling will work, but you need to make sure it is accurate.
If you are not part of the solution,
you are part of the problem!!!

Hi,
The pic is a little dark on my computer where the holes for the pin are, I can't see how much it is worn.

It should work to weld it, and make it the original size again.
The clamp holds the extension solid in the axle tube. You need good clamps, and the 2 bolts for each clamp need to be good, so they tighten solid. My Cub has grade 8 bolts there, and they are fine thread, I think.
The pin does very little once the clamp is tight. If the clamp is tight, the pin and holes should not wear any.
The Cub parts manual says the clamp bolts are cap screws, 1/2" x 3", 20 threads, with nuts and lock washers.

Below are pics from TM Tractor of the original style clamps, if you need them.

Something I have noticed on Cubs, if you are in a rainy area, and the Cub is outside, the clamp bolts can get rusted partly away in the lower part of the clamp, the dirt and water stay in the clamp, and rust the bolts. :)

I’d MiG weld the missing steel. Then rotary file it round using a 1/4” drill. Sometimes weld is hard to drill.
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.

Thanks everyone. I ended up placing a bolt in the hole and then used the welder to fill in the wallowed out part and then was able to grind everything flat again. It did take a little work to get that bolt out after welding and probably wasn’t the best way to do it but it did work. Appreciate the suggestions. Glen the bolts in the clamps were about half gone but have been replaced with grade 8. Thanks again.

make sure the pin is not worn out also, if it moves a little it will wear the hole out

I'm not a welder, but remember seeing something about using a brass rod to fill around as the weld wouldn't stick to the brass. Does this work????

Yes, that works, Bob, better yet is a copper rod if you can locate one. You weld around it, then just knock the rod out. It won't melt as easily as brass.
