Info on a Kimkin jack

[Dipnetfan]

I should never be allowed in a scrap metal yard without a minder. I brought this large rusty floor jack home on a whim. It says Kmkin on it and nothing else. Any info would be appreciated especially does it seem to be all there. It all kinda of frozen and Until I get it apart I can't figure out how it works. What appears to b a hydraulic ram is not connected, so maybe it's missing something. I've rooted around here but have not seen one like it. Maybe it's a clone? Any info would be appreciated.

Looking at the style reminds me of Walker 770 type. May be 1920-30s?

Thanks, I'm on it

 

[Shelbylex]

Please keep information coming - this is something rare and great!

You can also get in touch with one of the experts on the topic, HiBall, and see if he encountered this jack before

No word about this beast but I did get one wheel off. I may have to do some volume electrolysis.

Welcome to my world of frozen jack as well, Dipnetfan.
I picked up a vintage Weaver which is solidly rusted...

Please do a detailed write up - will try to do the same on mine. We might face similar problems working on them (though I will be probably much slower then you...)

Please make a picture of your jack from front towards the handle showing lower part next to the cylinder

That part with the sawtooth - is that a mechanical lock?

I found a Kimkin jack a while back and couldn't find out much about it either
It has an interesting badge on it.

Mine is quite different from yours

It is rusted up solid too.

Some awesome there Don!
I love finding 'ol odd stuff like that.

A few more pics. I have three wheels off and a few nuts. The bolts and spacers a getting looser. The 4th wheel is not cooperating at all. I’m working on drilling it now. Tomorrow might be the day

 

[Shelbylex]

What are you spraying on the bolts and nuts to loosen them?

 

[Dipnetfan]

Anything I can soak I’ve been using 50/50 atf and acetone. The rest knocker loose. Or liquid wrench. I spray it pound on it some and let it set overnight. Those bolts that have a sleeve I drilled a little hole and put stuff in there to soak. I got two loose that way so far. I’m gathering things to use electrolysis.

 

[Shelbylex]

I never used acetone and ATF mix. Acetone is highly volatile and should not mix well with ATF. How do you keep it on the part soaking?
Where do you keep the mix (? Special sprayer bottle) , or you just mix little at a time and pour it down on the bolts?
I have to loosen a lot of stuff including rusted holes with cotter pins in them
I will try to free the hydraulic unit if I can and try to open it...

I found a reference to acetone and atf on the web. I put it in a big can and soak something overnight or more. I’ve never tried to spray it, I use knocker loose or whatever for spray. I gave up on ever getting a cotter key out. I spray them and the next day pull on them til they come out or break. Often I have to file off the little ****.

Thanks for the info. Looks like these guys made some unique stuff. Mine looks to be a garden variety jack. I am still thinking clone of something, though maybe not. There are no markings or badges on it other than the big Kimkin.

I think so, but as yet nothing moves so I’m not sure what does what.

Thanks for the research RTM
You have identified my Kimkin jack

 

[RTM]

The evaporation of acetone is supposed to be the magic ingredient, do I heard spraying over dunking, but this is the internet, so no idea if it's the truth.

I made a little progress today. I found a rod the was about the same size as the shaft and pounded on it for 10 minutes. It finally moved and I drenched it with liquid wrench. I had to file the edges some as when I first hit it it mushroomed some. Still no movement on the last wheel. Hope to try electrolysis on Thursday

 

[Dipnetfan]

Well I have been making progress on this Kimkin jack. Still no real information on it but Ive got it a apart. I soaked and pounded on it for days. I tried electrolysis to loosen things but no joy. I finally resorted to the Sawzall to cut the shafts and separate the pieces. I pressed out the stuck shaft pieces with a 20 ton HF press. It was surprising how little penetrating oil had actually penetrated. Today I tried to immerse the big pieces in a kiddie pool with electrodes etc for rust removal. They are too big for a standard sandblasting cabinet. Ill report on that later. The jack has a damper to control release. It came apart and should not cause problems in reassembly.
