King Pins

Does anyone know the diameter or reamer size for my 49' F2 splindle bolts(king pins). Also, has anyone done the job themselves?

Shop manual shows the 'spindle bolt' pn 21A-3115-A to have a Mfg Min. O.D. of 0.812(inches) Same for F1, F2 and F3 except F3 Parcel Del.

Max I.D. for the bushing is 0.81325 (inches)

I have a reamer and king pins waiting for time to do the job on my 48............ maybe one of these days.

If you search kingpins there are some threads with that size, I don't remember it off hand. I replaced mine and it really isn't a big deal. Hardest part is getting the old ones out, I used a torch to heat it up and snapped the top off to drive them down and out.

I have a press so getting them out should not be a problem unless they are roached. I would think reaming them would me tricky. How long of a reamer is required?

By far the smart move here is to buy a factory Ford reamer off eBay, and re-sell it after you're done. Many machine shops are using hones to do the job, success depends completely on the skill of the machinist.

Good point about hone vs ream.. I found an older machine shop where they had the correct reamer and had done this before.

I had a tough time finding a reamer when I did them on my f-1 so I made one

I modified an old kingpin that was in decent shape to work as a reamer.... I ground the end of it down just a little to taper it except for one one part where I cut an edge on it on an angle. I then welded a rod on the the other end to fit in my drill... once I pressed the new bushings in with a c-clamp i used my homade reamer to shave them to the right size.

I have put 10,000 miles on them so far and they are still nice and tight... PA mountain roads aren't kind to steering and suspension componentes either!!!
