King pin removal

[NiftyFifty]

I always just sharpen a good chisel and just cut them down one side, then pry them out, it not like you need to save them, just be mindful not to cut into the actual axle

Just the same here about 1 hour ago ... like TodFitch I used the vise as a spindle press.

Also like the colleagues a socket ("A" in the picture).

I stopped my first attempt when I had a pretty good pre-load and also heat (190 - 210° F)  and nothing moved. Did not want to damage the spindle.

Second attempt with an additional support piece (U-profile, "B" in the picture) and also a little heat. Bushing ("C") relatively easy came then out.

Good success, also.

The vise didn’t work for me. The walls of the bushings are thin from wear and can’t get a socket on it and I could not apply enough pressure with the vise. Heat did not help. I put a hacksaw in the opening and cut 2 sides of the bushing almost through then tried a sharp punch to get behind the bushing. It just broke off small pieces. I tried the punch in the bolt hole and managed to break of a piece but didn’t loosen anything. I think I’m going to have to take them to someone with a press.

You may want to purchase what is called a cape chisel with is made for pealing bushings out of bores. It has a different shape than most chisels and is not really uncommon so that you should be able to purchase for less or $10 locally at least - - a tools supplier, welding supply houses, etc.

ebay also has a large selection of cape chisels.

If you have an air hammer, a muffler/exhaust pipe ripper chisel works well.  Better if you grind some of the depth off the rip portion so is isn't so aggressive.

Those come in two general types, the right one for this use looks like the left on in this set:

Unfortunately I don’t have an air hammer. Could I use one of these with a hammer?  What size cape chisel?

[Mertz]

I got them out. I did not expect them to be steel. I thought for sure they would be bronze. I modified a punch to make a small cape chisel. It broke on the third bushing so I reshaped into a shorter one. The last one came out whole. I had a deeper cut with the small hack saw and hit it with the chisel next to the cut. There was some scarring but I took a hone to it to smooth out the bore.

Steel backed bronze/brass bushings.

Must not have had any bronze left. They were pretty worn.

Victory is yours, yes they can be a pain in the butt.
