Any words of wisdom from anyone that has tackled removal, reaming and installation of king pins and bushings on a 1939 110?
I found the king pins and bushings, getting ready to order. Was hoping to fins ones that wouldn't need reaming, guess that does not exist. What size reamer and who carry it?

Thanks
John

Actually if you source the later style kit/s with needle bearings rather than bushings, you can avoid reaming. Wait...brain cell buzzing...you have a 39, which has the thinwall bushings, bushings only....thick bushings/needle debuted in 41....sorry. therefore my comment applies to 41 and later cars.

If your pins measure 0.866, then a rather common reamer should do the job, pix of one attached, not uncommonly found at larger antique car flea markets as it also is used for Chevrolet and GMC trucks and Corvettes thru 1962. It's a 0.868". Note that Packard was very emphatic in their shop manuals that if the bushings are oil-impregnated, they should be burnished and NOT reamed.

All else failing use a good micrometer and measure the diameter of the new pins, and then head off to a good machine shop supply store for a reamer. In the absence of other advice, I'd think about a 0.001"- 0.002" clearance for lubrication film.

You might want to look through my 1940 rebuild thread. This link starts on the third page.

Nice write up West on replacement of the king pins. I wish they all came out that easy, but I've had ones in other cars that needed to be heated to get them to come out after the decades of being in there.....

I had the blessing of working on a 50,000-mile car that hadn't been used since the late 1950s, and stored properly.

EXCELLENT write up West, thank you. Couple of valuable points I learned, the drift pins are directional and the bolts / washers for the shocks are "matched"

Not having much luck finding a shop or for that matter a reamer in the South San Jose area. Holding off pulling them off until after the Christmas parade on the 3rd.

Thanks again West !

I buy many of my machine shop tools like reamers and the like from MSC Industrial Supply, they have a huge inventory - let's hope what you need is a standard size.

I wonder if you could use an adjustable reamer?? John

I have found adjustable reamers as well as reamers of the proper size but none with a pilot so if I was to do this in my garage, I would insure concentricity of the two holes. Also a bit concerned about the manual stating it should be burnished, not reamed. Still calling local shops, thanks
