King pin puller

[GB SISSON]

Since I have no idea what a perch pin even is I made mine for king pins only. I used a 3/4" fine thread bolt for the pusher and put a chamfer on the pushing end in case of mushrooming. The only fine thread 3/4" nut I could find are extra lug nuts from a parts tonner. Not a lot of threads, maybe 1/2" worth of threads. I have pretty much completed my pusher but my bolt only has 1 3/4" of male threads and I want to weld 2 lug nuts together so I have a really tall nut. The side bolts are 5/8 coarse with tall nuts I made from cutting a coupler nut in half. A friend placed a 3/4" fine thread die in my mailbox an hour ago and I need to brave the ice and go retreive it. My plan is to use my 18v makita 1/2" drive impact on it. Any problems with using the impact?

After many years of abusing my hands, I decided to take my front axle assemblies to a spring shop. $ 20.00, and 20 minutes. And the axle assembly is stripped clean. I am not wealthy by any means, but I did it to save my hands from further abuse.

Yes, I get that but the closest machine shop is an all day trip and another all day trip to pick it up after it's done. Plus the ferry ticket is 50 bucks x 2 trips. Then there's the two days off and the fuel. Furthermore if I took too many parts to a shop it would no longer be a hobby, which is what it is for me. It's Sunday, I'm snowed in and bored. Perfect day to build a tool I use once a year at most. I realize my situation is far different than 'normal'. I totally understand why you do what you do and I get what I do. As far as hand injuries, This is the most recent of many. My new tool with the impact gun on the bolt gently lifts the old kingpin up and out!

Ok, here are some pics of today's project. After all was said and done I put the impact gun on it and watched the 'nailhead' of the king pin appear effortlessly before my eyes.. Tomorrow I will place a chunk of old kingpin or a socket so the bolt will push it right to the top and out. Really, I just need a longer bolt. Easy. The 'pipe' at the top is a section of a fairlead roller off a warn 12,000 lb winch I parted out years ago. Nice heavy wall, fit the 'nailhead' perfectly. I could weld some washers to the bottom piece, but it is more versatile as a puller this way. I am eyeing a Very nice steering wheel on a tonner in my woods. Should pull that with no problem.

Pretty clever!

Unfortunately I cannot say "No other tools were harmed in the manufacture of this device". I needed some bar stock for the bottom piece. Something that would weld well and not bend... Like some high quality tool steel. I was recently given a 5 gallon bucket full of large wrenches with many duplicates. A 1 1/4 proto combination wrench gave up 9" of it's middle. This became the two 4 1/2" pieces sandwiching the two stacked lug nuts for the pusher bolt.

I must have been lucky. I tapped the lock pin out on my '41 fordor and tapped the bottom of my king pins and they came right out that was with 129K miles. No telling if they were originals or not.

The other side was tough. My 3/4" fine thread bolt got to wandering and would not center on the bottom of the king pin. I then welded two 3/4" lug nuts as guide bushings for the long 5/8" draw bolts. Now it stays centered and she cranked right out through the winch fairlead roller. I have ordered an 8" long center bolt so I don't have to add a slug half way through. With my impact gun I should be able to 'push' out a kingpin in about 30 seconds and watch it fall onto the floor in utter defeat. Oh, and my Moog kingpins arrived today All parts were made in USA, even the thrust bearings, and are not the newfangled 'pre-honed type. 63 bucks on amazon...Details to follow.
