    I have, but only on smaller trailers with a single tongue. If welding was an issue, the factories would use bolts.

    Without seeing pics but from the description it should be welded. If a-frame couplers were meant to be bolted they would have bolt holes in them. If you don't feel up to it then have someone else weld it on.

    4.5 inch grinder with cut off wheels cut it alittle at a time to make sure you don't go to deep. I would do 2 passes on it after it is all cleaned up and if you have any doubts drill 2 holes and run some 1/2 inch grade 8 bolts in each side of the A frame and replace the safety chains with new solid ones.

    I own several trailers and have looked at many. I have never seen a coupler of this type bolted to a frame. Here's a shot of the type I'm going to use. The difference being mine has no holes in it.

    Cool

    My family has been in the trailer biz for more tha 50 years. The only bolt on ones i have seen were boat trailers with a single tube tongue or an aluminum tongue which my family made also. The trailers my dad and i made were all welded on either the A frame type or the single tube...Bob

    Would this be a good candidate for a bolt on coupler? https://www.dropbox.com/s/5cmlgj9dli...2009.59.05.jpg

    Default Trailer coupler removal

    Just reading the different post on this issue, might want to keep in mind if you do cut off the old coupler and reweld the new on YOU ARE RESPONCEABLE FOR ANY dammages that may accour from poor welding.

    By cutting off the old one it voids the FACTORY standard of were it was first made even if it from the 1950's

    I have done this type or repair before and yes you will need to weld the coupler on then bolt the jack on, the jack will fail before the coupler will.


    When welding the coupler on you will weld the undersides and across the back by the frame rails (other words FULL PENATRATION)

    Just my opinion take it for what its worth but remember you are liabale for what ever you do on this project.

    Just a note I've been in welding/fabrication for over 20yrs and have built trailers for Haulmark,Pace,Exiss... and built my own custom trailers.
