I am in the process of replacing my rear bogie pins on my 73. I have the assembly removed and disassembled. Does anyone have tips, tricks, or words of encouragement to remove the top hat and bogie pin bushings?

Call Kanomata at Applied. You will have to anyway because he has the
bearing reamer tool you will need to rent to size the new bushings.

Yes, I do. Those bushings are pressed in against a shoulder from opposite
ends of the bogie. This means, that they need to come out the reverse of
how they went in. I use a dremel grinder with a cut-off wheel in the chuck,
and grind a cut across the bushing, nearly completely through it to the
bore of the bogie. I then drive a specially ground chisel between the
bushing and the bore of the bogie. This lifts and shrinks the bushing so it
can be removed.
Ideally, what should be used there is an expanding adapter for a slide
hammer that just fits the inside bore of the bushing, and is then adjusted
to fit very tightly to the inside bore. Then, using the slide hammer, pop
the bushings out.
New bushings are press fit from outside to the shoulder in the bogie
itself. A mild pain in the butt. I use my 20ton hydraulic press.

Ken S.,
I just got off the 'phone with Bob D., talking about your dilemma. I tried
to call him back with the outer dimension of the bushings I have: 1.680"
I was going to suggest checking the inside of the hub to be sure whether
the bore is the same all the way through -- Jim H. just confirmed for us
that it IS NOT. There's a stop shoulder, as I feared, so using that
dimension for a "drive-it- outer" won't work. :-(
It's been over 20 years since I did my bushings (meaning they've needed
more attention for at least 20 years). I did them at the GMC Coop,
following Jim B.'s suggestions. That was to use a muffler chisel in an air
hammer to remove the bushings. That worked, but I also made at least one
groove in a hub -- bad juju. If I were doing them now, I'd either follow
Jim H.'s procedure or CAREFULLY use a manual muffler chisel -- NOT a
powered one. If you aren't familiar with a muffler chisel, it has a flat
blade, the end of which is concave so that it "peels out" a 1/8"+ path
through what it's driven against (normally sheet metal), hopefully without
affecting the adjacent surface. That is, it's intended to cut a muffler
flange off without damaging the exhaust pipe.
Not many of us have the blind puller Jim H. also suggests.
If Jim K. has a better suggestion, please share it with the rest of us. :-)

For some reason Carl's post only showed up on the forum and not the email
feed.
Here it is:

Thanks for posting for us emailers, Ken. & Nice work, Carl. Don't you
want a vacation in S. GA (including a little OJT for me)? I did a SORRY
job on mine 20+ years ago. Only TruTracs save my tires now!
