Four wheeler gearbox repair - monkers - 11-30-2012

I did this a while back, it is a gear box or transfer case or something like that for an ATV of a friend of mine, who is rough on things lol. You can see the lug cracked, and a chunk missing.

So I decided to make a new lug and cut the remains of the old one off. I had to fabricate a fixture to hold the lug in the right place to weld it.

Made the lug.

Put a radius on the lug to fit the gear box

Then had to cut the old crap off and clean up the gear box and fit the lug.

This is how I held it in the vise to do the lug removal surgery

Then I threw some bird ***** at it with the spool gun, and added a pad in a weak area

After welding I started cleaning up and blending with a flap wheel.

It came out ok, he was happy with it and its still holding lol
Thanks for looking. My TIG is a Squarewave 175 and I wasnt sure if it had the oomph to do it so I used a spool gun I have at work, and did it on my lunch breaks.

Nice repair

It would have taken a big TIG set to weld that up
The wire feed is not as prity as a Tig but the welds look plenty strong enough Smiley-dancenana

The time and care you have shown in the jig to set it all up is the impresive part Worthy

Thank you! Yes, getting it right is important;) better to spend an extra few moments with the set up then trying to figure out how to make it fit when its wrong :)
