knuck seat pan fix.

[gvg]

wondering what the best way to tackle this?
i’ve been told welding a new rod might burn some stuff.
was thinking to maybe drill a hole beside the larger one and sneaking a rod with nut on? any thoughts or personal experience. thank you

I know how I would do it- - - right or wrong, but I'll attempt to describe. I would drill and tap a 5/16 x 24 t.p.i. hole in a piece of 3/16, or 1/4" thick steel. That piece of steel would have to be just smaller or shaped to fit into the damaged seat pan hole. . . . With the tapped 'steel thing' inside the pan, use a long 5/16 x 24 bolt to correctly position the 'thing' and then tack mig, the 'thing' to the existing pan. I would suggest a friend with a wet rag to cool the tack welds. I think a number of judicious, well cooled tack welds would hold the 'thing' in place and not cause any problems with the foam seat padding. You could shore up the repair with a washer tacked to the outside of the pan and carefully massage the welds to match the opposite seat T stud.

There are a million ways to skin a cat, but skinners are the rare commodity Let us know what you come up with, Grant.

You can surround the weld area first with heat blocking putty. I have used this type of stuff to repair gas tanks and it works well.

All around the repair area like this. Put it on real thick to carry the heat away.

I welded the threaded insert on the pan for a seat T by submerging the seat in water, all but where I was welding. I took it slow and then put the seat out in the sun though it didn’t really get that wet and had no issues.

Good evening,
First, grind off any bits of weld left from the original boss so the surface will be flat.
I am with exeric on his idea but in addition, (after you have fixed the thread insert in place) I would make a stud like the one that is not broke off and I would thread that into the insert with low strength thread locker. Then I would make a boss that looks like the one that is not broke off and slide it on with just enough low strength thread locker to hold it in place.

Perhaps you can buy a T bolt if you cant make one.
Good luck,
Scooter

appreciate the helpful ideas guys!

i was originally thinking about just trying to use a toggle bolt and some nuts and washers as a non invasive fix.

but that wet rag product looks useful and with a few other tips in this thread I should be able to make it work!

thanks again!
