Are the King pins on a 29 front end held in place by the bolts that hold the small L bracket in place? If so are those bolts pressed in? From what I see by looking at a spare King pin there is a slot on one side which is probably where this bolt slides through to hold the King pin in place. Any suggestions to remove the King pins that you old timers can pass on to this first timer. Thanks.

So I have the front end stripped down where all that is left is the king pin "lock" bolts and the King pins themselves. I went to the manual and all I could find was that they said to remove the lock bolts. That much I knew. I have used some blaster and some heat and have tapped on them with no result. Is there something I am missing or is there a secret to removing the bolts? Are they suppose to simply slide in and out with some degree of coercion? Sure could use some practical suggestions. Thanks ahead of time.

Use a bigger hammer and smack them.

If the rest is disassembled, you can also press them out on an arbor press.

What good timing--I'm also replacing my king pins. I soaked the lock bolts in PB Blaster overnight and was able to smack them out without too much force. The king pins themselves came out with a few light taps. My question is on installation. Do the new king pins and bushings have to be pressed in? Or should they slide in with only minimal pressure, say with a piece of pine and light tapping? Or is this something for the machine shop? Thanks!

Generally the bronze or brass bushings will shrink a bit in ID when installed. The proper process is to ream them to size and then the king pins can be installed with light taps max.

Well I was finally able to remove the lock bolts. It required some heat on the unthreaded end and some pretty good whacks with a hammer. I knew the bolts were going to be replaced so I was able to smack them knowing if the end got burgered it wasn't a problem. I guess after 80 years the bolts didn't much feel like moving. The King pins came right out as was mentioned by others.
