Well, I have a stripped nut. It is one of the nuts that is welded inside the frame where the transmission bracket mounts. I have never tapped anything before and need some help.

Like, what are good taps to buy and the correct procedure and whether it will be as strong as the original threads.

I don't see any other option.

Help! It is warm and I need to get her back on the road!

 

Given the fact that it is a nut welded onto the frame, you are probably NOT going to be able to retap the hole. The nut will probably not survive the trque of the taping. If it were a taped hole in a peice of steel then yes you could retap it. Other wise see if you can put a bolt through the mounting hole and through the nut welded on the frame and tighten it down that way (this may not be strong enough it is purely a sugestion, I am not a mechanic or expert by any means and NOT RESPOSABLE for any damage that may reult).

If you want to try and retap the hole you should start by trying to retap the hole at the origanal size so just get a tap that is the same size as the bolt and try that first. If there is not enought steel left, you will have to re-drill the nut. with a bit slightly larger then the bolt and tap it with the APRPREATRE TAP matched to the NEW hole size. As far as durability I have no idea...

Proper taping process

- Put tap in tap handel (do not use a drill)

- put cutting oil on the tap and in the hole

- GENTLY and squarely start to turn the tap into the hole

- after a couple of turns give the tap 1/4 turn ccw

- Repeat the last two steps untill the widest part of the tap pases out the back out the nut

As far as where to buy quality taps go to an Industrial Suply store somthing that suplys to the factories and fab shops. Explain to them what you need to do and the material that you are taping. Also make sure you get the apropreate sized drill bit to re-drill the hole.

Any way

good luck

 

Thanks,

I think I'm going to cut a hole above the nut, drill it out abit and put a nut on the end of the bolt that I will pass through the old stripped nut. put lots of locktite on it and then weld up the hole. You are probably right, I don't think the nut would survive the tapping either, and I don't want to damage the metal any more than it already is.

 

Good plan,

Take care and good luck
