Geoff,
I have done it in a time of desperation. It works, but it's damn
hard on the biceps. A used king pin will do for this as they tend to wear
less than the bushings, but use your best judgement.
I used a cut-off wheel to cut parallel grooves in the pin. You
want about 3-4 cutting edges is all. A little twist is helpful. The best
would be to try and mimic the correct tool by tapering the start of each
step. Get a 1/2 rod to put through the fulcrum pin hole as you'll need to
do some heavy twisting. Remember not to twist backwards, even when removing
the tool. Use air to remove filings.
Your job will be made MUCH easier, if you pay careful attention to
installing the new bushings. Any burr or gall results in A LOT of extra
effort, even when using the proper tool. We find it best to make drivers,
but well sized sockets will do. Watch your grease holes and channels. The
cutting procedure is best done dry, btw. Test fit the king pin. If it feels
tight, look for high spots, if none are found, some emery paper on a dowel
in a drill will clean things up a bit.
Good luck.
