beastpath Posted December 19, 2008 Share Posted December 19, 2008 was putting my AC UCA on the passenger side of my truck today. started bolting them in, and the right hand side bolt got really hard to wrench down. backed it off a bit and noticed it was at a slight angle. Took it completely out and the first few threads have been stripped, and some of the threads in the bolt hole on the frame are damaged. suggestions please Link to comment Share on other sites More sharing options...
5523Pathfinder Posted December 19, 2008 Share Posted December 19, 2008 Sounds like time for a tap and die set and a new bolt Link to comment Share on other sites More sharing options...

5523Pathfinder Posted December 19, 2008 Share Posted December 19, 2008 Yeah, its not that tough. Get the proper size tap and some anit-sieze lube. Run the tap in with the anti-sieze on the threads. Remove, clean and repeat. Install bolt by hand to make sure it goes in. Reassemble as needed. Link to comment Share on other sites More sharing options...
94extreme Posted December 19, 2008 Share Posted December 19, 2008 i'd just drive it in straight depending on how much of that bolt is actually stripped/damaged. but if you can ream the hole, i'd do that first. Link to comment Share on other sites More sharing options...
Precise1 Posted December 20, 2008 Share Posted December 20, 2008 Get the proper size tap The key here is to use a cold form (aka roll) tap to reform as much thread as possible. Do not use a cut tap which will remove even more thread... B Link to comment Share on other sites More sharing options...

It has both male and female pieces to fix both external and internal threads. Here it is. I love this thing. http://www.sears.com/shc/s/p_10153_12605_00942275000P Good luck!

Precise1 Posted December 20, 2008 Share Posted December 20, 2008 I can't get a good picture to see them, but I suspect they are the same idea... That kit for $50 isn't bad. B Link to comment Share on other sites More sharing options...
MY1PATH Posted December 20, 2008 Share Posted December 20, 2008 this may not be possible for the UCA frame-nuts but usually if I need to clean threads I'll run a chase thru the opposite(undamaged) side to get a solid start. Theres a better likely hood of re-froming the threads unstead of cutting them when this method is used. Link to comment Share on other sites More sharing options...
Precise1 Posted December 22, 2008 Share Posted December 22, 2008 Absolutely!! I didn't think to mention that as I would assume that's the way everyone would do it when able... B Link to comment Share on other sites More sharing options...
