Fulcrum bolt won't come out!

I'm trying to replace my wishbone, A arm, lower support, whatever you want to call it. I have a nice new shiny rebuild sitting there waiting to go on, just as soon as I get the FRICKIN fulcrum bolt out!

If anyone has any suggestions they would be greatly appreciated. I have to get all this work done so when my new wheels and tires get here next week I can roll!
 
There is a little pin, #19 on the Moss Motors page for the front suspension that needs to be removed. Don't even ask why I know.
 
Yep, I got that pin out, but the fulcrum bolt is stuck to the king pin and won't budge. Eric Jones in Ohio gave me some tips, but still struggling.

You will probably have to take the whole unit off and work it out with some heat/vice and such. Once you get the whole unit out, you can take the blanking pate off the other side of the fulcrum and apply some pressure. I imagine you are trying to save the king pins? Good luck!!
 
I had that and even heat couldn't budge it. we finally had to cut the pin on both sides of the king pin. Took about a dozen blades. - This at my mechanic with "real" tools. I've attached a pic for what I expect you will find. Good Luck!
 
:smile:Ithink everyone has to deal with this issue. An extra grease nip on the blanking side might be a good thing.
 
Cut em out, not worth the pain. I have even broken tools on that part. They actualy weld them selves in there.
 
Rent or borrow a ~SAWZALL~ and cut thru the fulcrum pin on both sides of the king pin.
Then use a large punch to drive out the part that's stuck in the king pin.
 
I wouldn't mess with a Sawzall (sorry Nial). Get an angle grinder and a cut-off wheel. Makes it a 2 min job. The whole kit will cost you about $20 at Harbor Freight.
 
Ok, thanks for all the input. I did have to cut it out, but my sawzall blade wasn't up to it so I ended up going through about 5 high quality hack saw blades.

A neat trick my neighbor showed me for pressing things out: A large bench vise with two sockets, one big enough for the piece being pressed to fit through and a socket a little bit smaller than the piece being pressed. Put it all in the vise and you have a poor mans press!

But the job is done and I hope I never have to replace another one!

The rebuilt A arm I got from Eric Jones had the extra zert fitting on the back side of the bolt.
 
/bcforum/images/%%GRAEMLIN_URL%%/iagree.gif The fulcrum pin is a pain. I went through several hacksaw blades too, and ended up using the new kingpins anyway.
 
Yeah, once that pin is frozen (usually due to simple lack of lube/maintenance) the shortest distance to rolling again is replacement parts. It wallows out the arms and can even bend the kingpin. By the time you've pressed in new bushes, reamed/fit everything it's Christmas again. Hateful job.
 
Actually, grease can't and won't get to the area between the kingpin and the trunion pin.The pin is machined smooth where it passes through the kingpin. It's just a PITA, but you really do want that connection solid. Let it rust.

Or as it does not move, ie locked in place put a dab of ani lock when installing if you think you will ever be in there again.
