You can probably find a guided adjustable reamer locally...that will do the job.
As long as it has a reference to the other side while reaming you will be fine.
 
try finding a saw smith or similar they can resharpen them we do a lot of ream /rotobroach /and mill work our local bloke does wonders and its cheaper than replacements
 
Unless you do a lot of kingpins it's cheaper and easier to take them to a local machine shop and have them fit the pins.
 
You don't want the reamer from Speedway Motors. As flatheadmurre suggests, you want a "guided" reamer. With the reamer from Speedway there is no way to ream both bushings on the same plane. With a guided reamer as you ream the first bushing it perfectly centers the reamer for the next bushing. They are pricey so you might want to take TJ's advice and have a machine shop do it for you.
 
At one time, the 13/16" king pin bushing piloted reamers were common but times they keep a changin. A person would have to keep watching flea-pay or similar flea market site to find a good used one. The good ones were cut with multiple flutes and used a wedge action tapered pin to expand them about 0.010" max. They didn't have a lot of expansion range to them but they had enough to do the job as long as the bushings didn't have too much meat on them to start with.

This link illustrates the non adjustable types from KR Wilson but at least a person can see the length and size that they need to be. The long one is the one I'd look for. https://www.worthpoint.com/worthopedia/ford-model-6-v8-piloted-king-pin-1801056552

I prefer .010" adjustable types due to variations in king pin diameters in this modern era.

I have a local guy who runs a sharpening service do my RotoBroaches and I would usually recommend sharpening an old quality tool over buying a new one just about any day. However, I fail to see how a regular reamer could be sharpened without slightly reducing it's cutting diameter. Even if it could be done, I don't think one would tolerate multiple sharpenings.

Reamers are made to cut, only on the front cutting surface, the 45 deg area.

A "Rose" reamer, has no relieved flute area, at all. On reamers that have relieve flutes, those flutes are to smooth the reamed surfaces.

There are 2 types of expansion reamers, the non guided ones are made to expand and then be reground on the front and sides but, can be expanded w/o regringing, to enlarge a hole.

The guided expansion reamers, DO cut on the sides AND can be reground to size (to the limit of the expanding button) AND are very expensive.
 
here's my machine for sharpening reamers. its a KO LEE sumpthin or other, i forget the name. got it for 17 bucks at an auction. even came with a cute little 6 jaw chuck. now if i only knew how to run it !

$17 Bucks????????

That a Tool Room Grinder. Cleaned up and w/o the rust, it's a $3000++ machine, especially if it has more tooling in the cabinet!
 
I much prefer to have the bushings done at a machine shop that has a hone mandrel long enough to pickup both bushings. This way you get a totally precision fit - with no slop at all.
 
yes, mr frnkeore, its a tool room grinder. from my searching it seems that when the USA actually made stuff every large plant had one of these to sharpen tools in house. drill bits, reamers, even spiral reamers. but...you need to have some one who knows how to make it sing. it has more tooling, a manual, and even a coolant system came with it. KO LEE still makes them, not obsolete. it could be on its way to oregon for very reasonable!
 
Even though I've been retired since 2007, I do still have my machine shop. But, I couldn't justify a fair price and truck shipping, since there is no income involved.

I have a small (350 lb) tool grinder, that I've made do with, all these years but, nothing like your :)

If you can find one, hang on to it. it's about as good and cheap as it gets for a lot of things. Going it alone is fine. outside help is good too.

Depending on how desperate you are Phil. Nev Anderson , has one that we did mine a few years back, was adjustable if I remember ??
 
A couple of years ago, GB Sisson had a thread about honing king pins using emory paper wrapped around a wooden dowel and driven by a hand held electric drill. I tried it and it worked very nicely. We each started threads here and now, I can't find either one. I'll try to keep looking.
 
I prefer to take it to the local Auto machine where they use a Sunnen Hone machine . Lines them up and can be made to fit as desired. JMHO kerk
