I purchase the complete king pin kit for the 1932 chevy confederate, I pulled everything out of the box and started to check the size of the pins and the bearing. The king pins mic out to .735 thousand, I found that the bearing mics out to .760 thousand. For having a machinist background, it shows that the bearing is .025 thousands bigger. It does not make sense to have the bearings bigger in size compared to the king pins. Is this normal?

By "bearing" are you refering to the actual bearing or the brass bushings?

I am looking at the actual bearing. The brass bushings will have to be reamed once I get them installed.

That is correct for the bearings. They are a loose fit over the king pin.

Thank you. I was just concerned that with the bearing being with the twenty five thousand bigger, doesn't seem like there will be no contact with the king pin.

The bearing really has nothing to do with the king pin. It supports the verticle weight to mkae steering easier.

Do you have the correct king pin reamer? I have one if you’d like to borrow it.

Thanks for the offer. I did not catch your mail quick enough, I ended up going to Grainger and ordered a reamer. It was about 50 bucks, Just to use it one time will be costly, What is your reamer set up at. Did you have to remove the front axle to do this? If not how did you get the old bushings out and the new ones in?
thanks

Hi Al,
Mine is a reamer sold and designed to just do the early GM king pins. It has a pilot on it if I remember correctly. I will be using fairly soon as I am putting new king pins in a 34’ axle. I can actually put the bushings in and ream them tomorrow. You don’t need to have the axle out to replace and ream the bushings. You drive the old ones out, drive in the new ones with a driver designed to install the bushings, then you ream them. I’ll try and install them tomorrow so I can tell you better. Plus, I’ll get some pictures.
