radius arm bolts

[SteveMinnesota]

I am looking for ideas to repair the stripped treads where the 7/16 x 3" bolts go by my foot rest.Two of the three bolts kept coming loose so when I removed them the threads were worn. I bought some new grade 8 7/16 x 3" nc bolts but they dont tighten up either. If I have to retap what size do you recomend? I also thought of trying a 2 1/2" or 2" and see if it will grab then.

If the correct length won't grab the threads shorter ones won't either as the length is not what the problem is, it is that the threads are worn. Since you have one that sounds as the threads are ok on I would fill in the other two with a good product such as Lab Metal or JB Weld according to directions then after it has hardened I would replace the cup part with the one good bolt making sure the other two holes are lined up then drill and tap it then you should be all set.

Good idea. Thats why I asked.

I fixed mine by removing the steering box and went inside to put nuts on the bolts on the inside. I had to use longer bolts.
