Kingpin HELP 51 Mercury

I was planning on replacing the kingpins (spindle pivot shaft) on my 51 Mercury today. After removing the old bushings, cleaning the spindles and pressing in the new bushings, I find that the kingpins are .025 bigger than the inside bushing diameter.
This is the first time I have attempted this job on an old Ford or Mercury and am hoping to get some ideas from experinced folks.
What type of fit should the shaft/bushings be? Certainly not a pressed fit as they do pivot.
What can I do now?
Thanks

 

You have to ream the bushings to get the king pins to fit. You need a special reamer with a pilot on it. It will ream the bushing strait so the pin will just slide in with lite pressure.

Yup you need a reamer all right or some who has a set! If I was close to you I'd lend you mine or do it for you!!

 

machine shop should be able to do it for you. it shouldn't be expensive.

 

Just found this. Wouldn't this be the correct tool?

Trying to avoid removing the entire stub axle right now

 

I had brought mine to an auto machine shop to have them fitted to the new kingpins.

I know it's a hassle to pull them off of the a arms, but the machinist told me it was not your average reaming operation. Both bushings have to be reamed on the same centerline. I don't know if that tool on ebay has that centering capability built into the tool.

 

The tool is the same one I have and it will work. You have to have enough clearance for the tool to go out the bottom unless you are real carefull turning it back out the top. Use plenty of oil and take it slow. It's a little harder to find the 15/16 pins & bushings so the price is high. Not much room for mistakes.
