Spun a cab mounting nut
Im looking for ideas on how to fix this. I the cab mounting caged nut break loose when removing the bolt. I was able to get the bolt out by using a hole saw to cut a hole above the nut so I could hold it still.
Now I need to fix it - figure my options are: - 1) remove the caged nut and replace with a 1/2" nut welded to a piece of 1/4" steel plate. - 2) leave the nut in place, wedge some steel plate between the crossmember wall and the nut to hold it in place. Anyone done this before? |

Re: Spun a cab mounting nut
I would also consider a flanged nut as they give you more surface area to weld too.
Be sure to chase the threads afterwards as the can get galled up from welding. |

Re: Spun a cab mounting nut
if you have the hole now to get to the nut bend the tabs back tight and weld them together . the reason the nut spun was rust . clean the nuts threads with a tap and blow out . your good to go from there .

Re: Spun a cab mounting nut
Regarding the factory nut - are they lock nuts or normal nut. I would think a lock nut would be better since the bolts thread in from the bottom. If they are lock nuts then the tap would probably take out the "locking" feature.
