I see the 8mm nut and have removed it.
now- what's does it take to get the pin OUT??

is it threaded in or pressed in?

somehow I can't see brute force doing anything short of destroying it.

Keith,
the threaded pin cannot be removed that little nut only held the wedge shaped "cotter pin" in place until enough time and corrosion had permanently fixed it in there

to remove the king pin, saw through the lower fulcrum pin on either side

don't worry about trying to save the lower a arms, they are consumable (they crack and wear so by the time this level of overhaul is called for they are scrap)


hope this helps,
Norm

You can try to remove the pin, but often they are rusted solid to the kingpin. Put the nut back on even with the end of the threads and whack it with a hammer. If you're really lucky the pin will come out. It's OK if you destroy the pin, replacements are readily available and they're cheap. The last two cars I disassembled came apart without too much trouble. If the pin resists your efforts follow Norm's advice and saw through the fulcrum pin on each side of the kingpin.

Correct me if I am wrong, but that fulcrum pin is hardened steel no?

If the a-arm is going in the skip, you don;t even have to bother with the lower fulcrum. Just undue the top trunnion, pull the swivel axle off and toss the old kingpin and a-arm in the bin.

Almost that simple. You have to loosen the backing plate to clear the kingpin base, unfortunately, which means removing the rotor, etc., etc.

You need something that will cut hardened steel. Friction cut off wheel used here.
