I am trying to reinstall the king pins on my 1933 Master.
I pressed out the king pin, then I pressed out the oud bushings and installed the new bushings by pressing them in.
Now comes the hard part as the king pins are so tight that they are pushing out the bushings when I attempt to press them in. Do the bushings have to be honed in order to get the new king pins back in as they are so tight? Help!!!

You need a reamer to ream the bushings to size. I *THINK* the king pin reamer for a '32 chevy is a 47/64 which will mic. @ .734 OR to get even more technical, .734375
I am NOT sure about a '33 in that being the same diameter wise.
The only trouble IS.. that finding these incroment reamers are next to impossible to find on the intrenet inless you have an outlet or KNOW of an outlet for machinists tooling. You could try ebay but there's no promis of finding it (which you may)
KBC tools has a 47/64 (if you find that is the correct ream) BUT, it is a chucking ream, not a hand ream which is what you need if the axle is still underneath the car. TOO, preferably, purchace a SPIRAL FLUTE ream as it leaves a cleaner finish than a straight flute. But if you MUST purchance a straight flute, purchase one with ATLEAST 8 flutes, if you can help it.
I nearly have a full aray of reamers myself (NOT BRAGGING) and i probably have exactly what you need, however i do not loan tools anymore.
In my shop, quality is a standard, NOT and option.

Take the pins and knuckles to your local automotive machine shop. He will hone the bushings to size for you. It's not very expensive.

Oilspot,
Thanks for the reply and davice. I will be contacting a friend who owns a machine shop. I thought that they would have to be cut down a little. Thanks again for the advice.

In most cases king pin bushes need to be reamed to near size to allow for any alignment issue, then honed for final fit.
