Nice refurb thread! Im enjoying it.
ok, here's the pics of the knackered ram...
Cad plating is done, I'l pick it up tomorrow
Im guessing by the pic of the ram that the seals are inside the unit and in the form of a Vee packing more than likely, It could be a rod Ucup but unlikely. If thats the case that ram is shot, account the sealing surface is the outside of the Ram instead of being your typical Piston type seal which would make that nasty pitting still functional believe it or not. I would like to see some pics of the inside of the unit if thats possible.
Now things are becoming more clear, The piece that is pitted real bad is hollow on one end? My curiousity is peaked, get the guts out of inside so i can see them please. LOL Blackhawk made some jacks back in the 40's that had a similar Sleeve design. Believe it or not that Pitting shouldnt affect that jack one bit, Its actual sealing surface is inside and the only thing that runs out the outside is a scraper that keeps foreign materials out.
I know you've been busy with your new vise, but have you made any more progress on this project?

Have you determined if the hydraulic system is rebuildable or not? Looking forward to more updates on this most interesting floor jack.

What are you looking to do with the ram problem? Any thought to welding some material on it and then having it machined back down to spec?
Just curious... this is a cool project and one that should be completed.

Rick,
If it needs a sleeve it is not a big deal, anything is repairable as you know. It just takes more dedication on the really knackered stuff. This jack has great lines and the castings are a work of art, you gota fix it!!!

Everything's lookin good, except the ram. You've probably all ready thought of this & it's probably not cost effective, what about having a machine shop make a new piece? If the inside of the cylinder is jacked up also, maybe it can be honed & a slightly oversize ram made?

ZRX61 -- so whatever happened with this jack?!
I found this thread today -- I'm a bit behind the times, I know -- and I enjoyed reading it, but then it simply ends, practically in the middle of a sentence. And there's no resolution!
Did you finish the resto? Did you give-up on it? Is the jack waiting patiently on the back burner? Did you scrap it? Are you going to make a new ram on one of your South Bends? What???!
The suspense is killing me!

ZR6X1....any progress on the rebuild?
I stopped. That ram is scrap. If anyone wants it come pick it up.
The real pisser about this jack is that it has a really stupid design on the handle so that it is designed not to raise up past about 30deg so it would end up taking up about 6ft of floor space. If the handle would raise to vertical (like any normal jack) I might think about finishing it.

There was a reason for this handle design and they were not the only jack manufacturers to utilize this crazy idea. First it made moving a jack around the garage a dam site easier. This because when you raised the handle up high enough to move the jack it would roll on the two front wheels instead of all four. Try it and you will be amazed how much easier it is to position the jack.
The next benefit was in the manner you stored the jack after using it. This jack was never intended to lay flat on the floor. See the two prongs in front of the front wheels you're supposed to lean the jack up against a wall so it takes up less floor space. So again it is stored in a vertical position thus as I say it only occupies less than a square foot of floor space.
Lastly it has a downside as you can imagine since when you are actually using it the handle winds up really being in the way and therefore and thusly providing and impediment for other people or yourself to trip over while working.
I have a Walker and Blackhawk versions of this type of jack and I am not especially fond of them. The Blackhawk (always one step ahead of he competition) did provide a feature that allowed one the fold up the handle by pulling on a tab on said handle.

Good effort to bad about no finish, oh well, lesson learned, I will leave old jacks to guys with endless free time!! I took on an inground hoist for my new to me shop, got the hoist reeassembled blasted,por15'd,filled with oil and new seal, works great but now find out property I am buying has 5 liens on it!! I cannot believe how much time can be eaten up ******* around with this stuff!! I just look forward to using the old hoist someday even if it is just a secondary to a good 2 post!

Bummer, good thread too.
I fully understand, I've got a few scrapped projects hanging arround here.

In the case of the Marquette it is the INSIDE of the hollow ram that has to be in good condition. The inside of the ram fills with hydraulic oil and this oil stays in front of the seal assembly shown inside the pump body. There should be no oil outside the ram or behind the ram seal. Be aware that the seal runs inside the ram, not outside. The rust pitting outside of the ram is just a cosmetic problem, it does not affect the working of the pump as this surface does not seals any oil. You have to check the inside of the ram before discarding this jack. If it is in good condition with no rust pitting then you have no problem. You could fill that pitting on the outside of the ram with bronze or other type of filler. I see that you have yet to take apart the release mechanism in the pump that is under the short lever in the back of the pump. This release looks like it works like the Milwaukee jacks were the release is always in the closed position because it has a strong spring, inside the pump, pushing on the release needle.
