Default Re: King Pins Anyone in MN that can do them

Yep. The F1 King pin is 0.8125.


I did it myself, believe it or not. I used the cheapest chinese made adjustable reamer from amazon to do the job. It was around 8$ shipped!!! It has a 3/8 square which you're supposed to turn the tool with. On this square however, I placed a 3/8 socket which had a good perimeter fit in the opposite bushing to act as a pilot. For reaming, I used a normal spanner on the outer adjustable nut on the opposite side of the reamer. Once tight, it does not go tighter even if you use it to turn the tool. OK, it is a little fincky to readjust and took me 3hrs to finish this one off job. But in the end it was done the proper way with a guided reamer, the result is great now and I got around to buy a pilot adjustable reamer which is around 250-300 Euros here. All I spent was 8$.

I hope you get how I did it, or I can dig in my files and post a picture from the process
