Found a Jack

Found a Jack. Now with ongoing resto pics...

Now with ongoing resto pics

So, can anyone tell me anything about it?

 

[Hiball]

Judging by the frame only im guessing "Walker" and by the looks of it a Rust nightmare.

I'm in the aircraft resto biz, piece of cake to bring that jack back from the dead

What can you tell me about Walker?

What can you tell me about Walker?

The Short version: They started making Mechanical jacks in the early 1900's and somewhere in the 30's they introduced there first Hydraulic version, Over the years they dominated the hydraulic field, inventing the first "Quick Lift" technology dating back to the 40's. They sold out to Lincoln Lube in the 80's and then Lincoln sold the hydraulic line to Hein Werner in 1994 and HW in turn totally canned 60 years of there own heritage to soley market Walkers design. The New HW jacks still utilize Walkers design and previous model numbers with little changes over the last 75 years which include moving the resevoir plug and Tank nut style.

Where were they based?

 

[Hiball]

Where were they based?

Racine Wisconsin i believe.

 

[ZRX61]

ok, thanks I'll go back & drag this thing home I guess

 

[ZRX61]

Ok, dragged it outside to get a look. Handle is actually steel, not wood...

A bit of soap & water reveals.... A Marquette..

 

[Hiball]

As you can see its a marquette brand Jack. Kits are still available and i believe there is another GJ member here that recently picked up a similar jack. That jack is not to be confused with the Import Marquette line that marketed in the 90's. Your jack is much older and i dont belive it was made for many years, As far as that goes ive never worked on one so im clueless on its inner workings etc. The only kit i have available includes models K, KF and M and they are all 2 ton jacks.

 

[ZRX61]

The one issue I've discovered so far (apart from the fact it doesn't pump up) is that the handle will only move upwards about 30degree from horizontal.

The end of the release lever on the arm is also broken off so I'll need to fabricate a new. I'll ****** about with it this weekend & see where i get.

Thanks for the info.

Hiball was referring to my jack, here's pics...4th pic is on the handle-maybe a model# & the 5th pic is at the base of the handle. Great old jack. Check my thread for details.

Can I get a pic of the release lever it as mine is broken off where it passes through the flat part of the handle? I need to fabricate a new one. thanks

I'll snap a few pics today & post for you. Does yours have any #'s on the handle or base?

 

[ZRX61]

Now with pics:

This is as far as the handle will raise...

Underside after a bit of wire brush & kroil....

 

[ZRX61]

Dagnabbit, that's what I forgot to look for, brb.

OK, it has *K 18* on the handle, nothing visible on the base

..but I haven't got it moving yet where I can see all of it. It's still locked up. The handle will raise enough to move the plunger doohicky in & out about 1.5in, but I can tell there's no pressure in there to lift the arm etc. Then it hits something *solid* internally.

On the upside, the rear caster that was locked solid now spins freely... so I do have progress of sorts

Next step is remove the handle so I can get the rest of it up on the bench for disassembley/investigation

 

[stricht8]

Cool Jack! Hope u can get it working.

 

[ZRX61]

Removed a cover & found where i assume the hydraulic oil goes.. except there's ****** all in there...

So while I had the cover off I cleaned it up a tad... I think the little *** on the top is a breather?

& the handle where the K18 is...

 

[ZRX61]

Managed to seperate the handle & then just about gave myself a hernia carrying it 70ft & getting it into the blast cabinet. Loaded the cabinet up with plastic media. The fine white kind, not the usual "mostly white with colored speckles" coarse plastic.

& found another number (K7) on the bracket the arm bolts to:

 

[ZRX61]

Next stage is to seperate the side plates & blast it a bit more to get the bits I missed because they were inaccessible.

 

[Elroy]

That's a neat old piece.

 

[ZRX61]

More progress
Managed to free it up & get the arm all the way up.... however that was by manually lifting it, it won't stay there without the piece of wood wedged in there.

Next step was to knock the side plates off but I need a 1 -1/4in socket so this means...

*fanfare*

A trip to the toy, er, tool store! YAY!

Hey ZRX61....got some pics. 1st pic is the lever that lowers the jack-I think the one that is broken on your jack. 2nd pic (M17) is the smaller "T" handle used to adjust the height (angle) of the main handle (as seen in the next 3 pics), 6th pic is the part (M6 or M8) with the 3 indents that positions the main handle at 3 different heights/angles (flat, about 30 degrees, & about 45 degrees). The overall length with the handle laying flat is 7', the main body of the jack is 45" long, the handle is 39" long. More pics in next post.

 

[deathbound]

More pics.....1st pic shows right inside of frame (M7R), 2nd pics shows left inside of frame (M7L) with (M15) which is the pivot part that the lever used to lower the jack is connected to-R & L are pretty self explanatory, 3rd pic shows 1 of the swivel casters (M18A) both have the same#, 4th pic shows the underside of the frame with the rods that raise & lower the jack, 5th pic shows underside of the main body of the jack, 6th pic shows full view of the jack, 7th pic shows the jack folded. Hope this isn't confusing. Good luck with your jack, it's looking better already.

 

[ZRX61]

Perfect! Now I know what kind of handle I need to weld onto the remaining piece of rod for the release
Looks to me like the ram, levers etc on the actual lifting part on yours is the same as mine.

Managed to get the 4x 1-1/4 in nuts off. In the morning I'll take off the other smaller nuts, front wheels etc & attempt to seperate the side plates from the ram.

 

[deathbound]

Cool, keep the pics coming. Anxious to see how it turns out. I wonder if yours is some sort of "K" model & mine is an "M" model????????? Mine has the same filler cap as yours, forgot to snap a pic though.

 

[ZRX61]

It's fighting me this morning. Managed to get one of the 3/4in pins out but the other isn't moving. Also managed to get the front wheel spindle about 1/3 of the way out. Time to break out the acetone/ATF mix and/or the *blue wrench*

Also filled the rezzy with ATF last night to see if I could get any pressure, no dice.

Anywho, coffee break over, back to the task...

 

[ZRX61]

I think I'm done for today, going to take the Kaw 11 out for a bit. Managed to get one side plate off & found another number:

Going to leave it alone for a while while the penetrant does it's thing. Got the front spindle out tho.

I see some beadblasting in my future.....

Right now I'm thinking paint it while apart & have the hardware plated with Cad 1.

 

[ZRX61]

Well the planned ride over to a local bar to look at some boobies didn't pan out as it's now absolutely ******* down.. So I spent another 2 hours in the garage working on the jack. Right now the only hold up is seperating the other side plate from the main gubbins. It's seized on this one stud:

Stuff....

Found yet another number..

The mess...

Bluergh..

Once I get the side plate seperated I can get this bit disassembled & in the cabinet..

 

[ZRX61]

Monday morning success! I got the other side plate seperated are resorting to my largest *inertial adjustment device*.. (the sledgehammer)

Now I can get the rest of the gubbins apart, cleaned up some more & maybe even start painting today. Hope I can also get the ram disassembled today.

 

[ZRX61]

More progress.

This is where I'm at right now:

All the gack is off the parts & the next stage is a bit of bead blasting on some parts & aluminum oxide blasting on a couple of other bits.

 

[ZRX61]

ok, I'm done for today, except for a trip out for red paint.

Got the parts for the cad plater beadblasted clean:

Ram is looking a lot better:

 

[ZRX61]

& finally, the part # on the main gubbins..

 

[GDA]

Great thread! Us guys can learn alot from just watching the disassembly and clean up. That's gonna be one cool jack once you get it rebuilt and restored.

Q - do you know if that deep red is the original factory color? What's needed for the hydraulics rebuild?

 

[deathbound]

Major progress.....lookin good.

 

[Even 11]

Very cool thread!! Where does one find a jack anyway? Looks like it was in a riverbed from the pic!

Close, it was in a shed that had a drainage channel running thru it.

 

[egdede]

That's a neat old piece.

Didn't Elroy have some art-deco influenced tools that would look right at home with this jack?

 

[ZRX61]

Slight set back. Got the ram apart today, it's toast

So options are:
1: Paint it red, leave the handle off & hang it on the garage wall as art.

2: Have the extremely pitted ram welded up & reground etc...

3: Find another ram

4: Make another ram.

I'll have pics of the damage later tomorrow.

Dont be dissapointed show me where the damage is, It may not be as bad as you think.

Isn't this great fun.

Elroy would say you'll play hell finding a replacement ram so have one made if the damage is in the high pressure zone. When it's all said and done you'll be glad to have a working jack. Elroy burnt a good 50 hours plus on the Hein-Werner OS.

Want to take a bet on how long this rebuild takes???

Keep after it.
