Removing seized Kingpin.
I need to remove a seized kingpin from the 41 ford car chassis that I am working on.
Anyone have any favorite techniques that they can share?. I do have access to a press if necessary. Thanks for the response's Torchie. |

Re: Removing seized Kingpin.
I am working on fabbing a jig for doing this. I based it in the KRW fixture, with the main change being a slip fit to the pin for use in a press instead of being threaded. I am making it so it will keep the pin square with the press. I will have to make a different one for each major change Ford made to the spindles as some of the angles and setbacks are different. Rod

Lots of heat and the biggest sledge hammer you can swing.

Re: Removing seized Kingpin.
I once needed 20 tons of pressure to press out a kingpin on a 55 F 100. I think that a BFH will bugger up the spindel or axle so that you will need to replace something. Take out the axle assemble and strip it down so that a machine shop can press it out.

Re: Removing seized Kingpin.
If you do not have access to a KRW tool (or equivalent) it can be done with a BFH. I have done many (prior to acquiring the KRW tool) utilizing the hammer (4#) method.
From my experience, once you can get the pin to move up a little, tap it back down. Hammer it back up a bit further the next time, then back down again. It'll come out... just be patient.

Re: Removing seized Kingpin.
Is it stuck in the axle or (spindle, probably unlikely) ?
Suggest heating the king pin & axle boss a dull red. Let it cool for few hours. Use Kroil on king ping & boss id. Let it sit an hour or two. 20 ton press, prefered or BFH should do it. |

Always used the BFH. Cried a lot but always got it out.

Re: Removing seized Kingpin.
OK. I'm ready for my daily "learn something new".
What's BFH?

Re: Removing seized Kingpin.
Ahhh. That's probably a lot like my BSHYCS (Biggest Sledge Hammer You Can Swing) I was talking about.

Re: Removing seized Kingpin.
Any hammer over 2 pounds is a "speed wrench".

Re: Removing seized Kingpin.
The only disadvantage to using heat is in not knowing how to do it. The objective is to expand the "holder" without expanding the "holdee". This requires a rapid heating technique accomplished with maximum rose-bud sizing and, sometimes, a pair of torches.
Slow heating with "normal" torch methods will only serve to expand all components at about the same rate and do little. |

Re: Removing seized Kingpin.
Sounds like it stuck on the bushings. Heat it up and pump grease into the zerts. Watch out for hot grease flying out . Won't take much to melt the gummed up joint.
You can also get stuck kingpins out if its a complete car using a bottle jack or portopower against the weight of the car but you still need a rosebud. I run into this on everything from stuck king pins on old fords to bulldozers and backhoes. |

Re: Removing seized Kingpin.
50 years working on old cars gives me a lot of back experience on what works & what does not. This is just to say that what worked last year, does not work today...go figure. Using torches to heat is always the first on my list......and if does not dislodge the part....time for step II. The heat is great as the # 1 step because it does 'something' to help 'unglue' two adjoining metal parts through either expansion or breaking down rust. Mashing at red hot metal may be more harmful since one may be 'riveting' metals together, so working the cool metal is in order. Presses and BFH with patience is the definite next step. I guess we are ALL in the same boat.....Robert

Re: Removing seized Kingpin.
I am laughing ONLY because there is soooo much truth to your statement.
Once I had acquired that KRW tool, it made me wonder how I did all those pins without it. Yeah, younger and more stubborn no doubt...

Re: Removing seized Kingpin.
i just did mine last week, wouldn't budge with a 8 lb sledge, put heat on the axle and got them started with the 8 pounder then finished with a 4 lb, it wasn't bad but you need heat or a proper puller
