Marquette Model M Floor Jack

[bigw1231]

Afternoon All and hope somebody can help. I have from my dad's estate his old Marquette Model M Floor Jack. The serial # is L234184. Its complete and I know he had it since at least the early 60's.

Can anyone give a me an approximate age of this? I would like to rebuild it and make it functional in the garage, so I have a couple of questions.

First and foremost, is this something that one who has NEVER taken apart a jack before can accomplish?! I know cars, and I can do bodywork, but for some reason, this is intimidating to me!

Second is rebuilding kit(s). Who is the preferred source, and could I be so lucky that there is one kit to do the whole jack?

Is there a manual to tear this down and if so, where can I obtain a copy?

Lastly would be the finish. I would remove all of the old paint, but I wouldn't sandblast as there really is no rust. But when I refinish it what is the recommended paint type, ie enamel, urethane, powder coat, etc, and would anyone know the correct color(s) it should be?

Thanks to any and all for their input and responses.

Here is what I can contribute. You may have to do some detective work in finding the right jack kit.

All I can find on the pump is M1

And last but not least, broke a piece that I believe is to the release valve. Any suggestions? So two things, yes I learned how to submit photos and I will try to make them all one post in the future and #2 rebuild myself or send it out?

Any and all comments welcome. Thanks!

If you plan on using this jack and you've never rebuilt a pump, send it out for a professional rebuild. For the 100 or so dollars bench fee, your life is worth it.

Well just got back in from disassembling the lower part. God I am glad I took pictures!! That broken piece is nothing more than threaded rod sio unless it gets winky in the pump first crisis averted! Thehorse...any recommendations?! Feel free to PM if you prefer!
THANKS!!

In the case of the Blackhawk jack that I restored, it was extremely simple to find the kit. Around here, because there are still a good number of farms, hydraulic repair shops are easy to find. I would try to find one in your area and see if they have any sources for pump kits should your detective work not pan out.

Someone has the rebuild kit for your jack. It's just a matter of finding it.

Ok Pump is sent off to get rebuilt. Took this jack apart and with the exception of hardware, its at redi strip.
So now to all of the Floor Jack Experts out there....
1)Any idea of torque value when I put this together?

2) Solid Rivets...where do I get

3) Even though I removed some cotter pins on this guy, would the consensus think these were all at one time solid rivets?

4) Inside the rear (Swivel) wheel housings there was a bearing. I discovered what was left of it when I took the swivel apart. Any ideas on a replacement?

5) Opinion Question....Use the original hardware, (Square heads bolts, etc,) or upgrade to 6 point grade 5 or 8?

Thanks to all who look or have suggestions!

Here is my 2 cents worth:

1) If you are talking about the nuts and bolts-then tight. I have taken mine apart and I put it back together as tight as they will go.

2) If you are planning on taking them out I would not unless you have the ability to put ne ones in. They would probably be need to be cherry red and then bucked. But here are two places:

1. www.bigflatsrivet.com Big Flats Rivet Company (New York)
2. www.rjleahy.com R. J. Leahy (California)

3) I am guessing probably not. Cotter pins were used extensively back in the 30-40's. But then again I would need to see the jack to make sure.

4) If the bearing is caged ball bearings-good luck. If you search for 'mechanical jack restoration' here, you will see what that gentleman did to rebuild his bearings. Sorry I don't remember the post. You may try McMaster Carr.

5) Always original hardware when possible. It is generally better than new-unless it is aircraft grade.

Finally back on this project. Frame and all parts back from getting dipped and cleaned. Sent the pump out to get rebuilt, and it arrived yesterday. Not that anyone cares...!
So here is the question of the day...
The rear swivel casters had loose ball bearings in them. I ordered new ones, but can anyone point me in the direction of how they work? It is just a guess, but I would think that I am to place grease in the cup, line the "floor" of the cup with the new bearings. Just one layer? How can I determine if the caster stem needs attention? I am inclined to think that the bearings are there just to help the swivel, and the load on the jack is actually on the caster assembly. Any/all info would be greatly appreciated!
