What started off as a simple kingpin disassembly has now grown like a snowball rolling down hill for me today. The passenger side came apart without much of a fight, the bolts from the spindle to the backing plate needed a few hammer taps but everything came right out,even the kingpin. The drivers side on the other hand has been a much different story. The bottom left bolt through the spindle was easily the tightest most seized bolt that Ive ever encountered.The castle nut easily came off but the shank of the bolt was seized in the spindle. I soaked it all week with PB Blaster then tried a BF hammer,a breaker bar with a pipe extension, a propane torch( I dont have an oxy/acetylene), a 1/2 inch impact--nothing would break it lose from the spindle. Finally I cut off the threaded portion and started drilling it as a last resort, I had to drill to almost the diameter of the bolt and still beat on it to get it to separate. Unfortunately I egged out the hole in the spindle so now I'm on the search for one to buy, does anyone have any ideas where I can find one? My next issue is that the pin that goes through the kingpin is equally as tight so now Ive got figure out how to remove that one. I tried knocking it out and that only mushroomed the end of the pin. I really dont want to drill this one since if something goes wrong here I could end up trashing the whole axle. Any Ideas?

 

What year is the truck, what series?

 

1964 F100.

 

 

Thanks for the help. I'm going to download the parts manual tonight. It looks like I need #3105, is that the whole number? It seems short for a part number.

 

B7C-3105-A .. Front Spindle - Right/Left is the same / Obsolete

1957/64 F100/250 2WD

No Ford dealer or obsolete parts vendor has any NOS, none on ebay.

Try: Flashback F-100's in Reidsville NC (336-421-3979 ~ flashbackf100s.com).

 

Do yourself a favor and take the axle to a machine shop to have it done correctly. They make oversize kingpins if needed.

 

Thanks again , I'll give Flashback a call. I'm sure that I can find one somewhere. The pin that's stuck is the small pin that holds the kingpin in place, not the kingpin itself although that could be seized as well. I have a feeling that it's not stuck do to corrosion, I'd be willing to bet that after 55 years hard work they have just basically been jammed together.Taking the axle out and having a machine shop do it is probably my only option.

 

Knock the nut loose but don't take it off. BFH, like a 4lb+ steel job. Eye protection. If you can get a clean hard smack generally the shock will make it loosen up. Then put a pin drift in an air hammer and drive it out if it is still slow to move. Note the drift must be almost the same diameter as the lock pin, otherwise you swedge the pin in place like a rivet.

Getting the king pin out is another animal. I have an OTC 4240, 30 ton portable press. I have yet to stumble on a king pin it won't budge but it was expensive. You may be better off taking the whole beam assembly to a shop the has the capabilities to do this type of work. Have them install and fit the bushings while you are at it, unless you already have the reamers and experience.

What side of PA are you on?

 

I'm in southern PA near the MD line,Chambersburg is the closest PA town. I may be able to cut the swollen end off of the threaded portion of the pin and get the nut back on it. I thought about using an air hammer, I dont have one but I do have my 4X rivet gun in my toolbox at work. Given how sloppy the spindle is on the kingpin I dont think it will take much to drive it out. BTW, Flashback F100 has a spindle for me when they get back into town.

SUNBURY MOTOR CO. in Sunbury PA has 1 = 570-286-7746 extension 266.

GREEN SALES CO. in Cincinnati OH has 10 = 800-543-4959.

CARPENTER NOS OBSOLETE PARTS in Concord NC has 11 = 800-476-9653.

 

do yourself a favor, pull the axle, bring it to a machine shop and have him press out the kingpin lock before you screw it up, he can also fix the whole you egged in the spindle by pressing in a bushing. And have him do the kingpins while he has it.

 

I'll be pulling the axle this weekend to figure out how I'll go about this. I don't really have confidence in any of the machinists around me which is how I got into the situation yesterday due to me not having the right tools for the job. I've found one guy who said that he can ream kingpins and I don't trust him at all. " I've got every reamer there is" " I've been doing this for 50 years" yet he didn't know about line reaming the bushings . Im going to buy an adjustable kingpin reamer for $120 and do it myself.

 

Unfortunately you are a 3 hour ride for me. We all keep saying machine shop, but big trucks still use a larger version of what you are dealing with. Perhaps there is a well equipped big truck repair shop near you? I would think they could at least get your other knuckle off the beam. Given the F100 has something like a 3/4" diameter kingpin I doubt the big truck shop would have a reamer that small.

The good news it's peach season!

 

I live near I-70 and I-81 so there are plenty of heavy truck shops around here, I might check with some this week, at least to just get the pin out.
My neighbor has 4 peach trees, I can't eat them fast enough!
