New Acquisition Milwaukee Model 20 2 Ton Jack

[LawnBoy-5247]

Today I was at an estate sale and noticed the jack in the corner setting in a pool of hydraulic oil, I was able to talk the guy down to $20 and decided to pull the trigger. After looking the thing over I think the only parts it needs are a seal kit and a new rear caster, and other than leaking oil it functions as intended. I also plan to repaint it when I rebuild it since someone gave it a terrible paint job at some point in its life. This will be the first time I mess with hydraulics but I believe this should be simple. Do you guys have any words of wisdom for me?

Here is the problem caster I have no idea what they did to it exactly but I believe it may have locked up and the jack continued to be drug around. Edit: It appears the jack may have been dropped, cracking the cast iron caster wheel and causing it to lock up



PS: If anyone knows what is going on with my upside-down pictures please let me know I cannot figure out why it is happening and don't have this problem with any other forums

You got a great deal there. My only words of advise are, cleanliness is next to Godliness with hydraulics, and don't butcher the tank nut removing and installing it. They usually use a special tool available only from the manufacturer to prevent unauthorized service from untrained shops. Make a socket from a cheap Harbor Freight axle socket. Good Luck.

Today I removed the hydraulic unit and the casters, it appears the price of a new caster is around $70 from Milwaukee but I believe I may be able to source just the caster wheel itself. When I cleaned the rear casters up I found that the casters are Bassick model 268 casters. there are several on eBay like it so I may be able to purchase one of those and use the wheel from it to repair my caster.

Here's my rebuild thread:

The parts are pretty cheap to get directly from Milwaukee. The paint color is Massey-Ferguson Red. I bought implement paint from Krypton to refinish my jack.

I think I may have a used caster wheel laying around, an exact replacement, as I've got two Blackhawk jacks that used the same Bassick casters. I'll be back home tomorrow and can check then, if you're interested.

paulsomlo, I would be more than interested in that,

stonesfan68, Regarding your jack, what did you do to seal the plunger holes when you blasted the hydraulic unit. I have access to a small blast cabinet and am planning on blasting all the small parts and potentially the frame if it will fit in the cabinet, but I have no previous experience in media blasting and am trying to figure out exactly what I need to do to prep the parts.

Hydraulic unit cleaned up somewhat



Nasty oil from jack

I would be hesitant to blast the hydraulic unit - I'd clean and strip it. I'll report back tomorrow on the caster.

Here's what I've got:

The diameter is roughly 2.43", width is almost an inch. One thing you'll want to check is wear in the caster frame. On mine, I found that the caster frame was worn to the extent that the caster was tilted and rubbing the jack side plate as it swiveled.

If you can use it, it's yours for the cost of shipping. I'll send you a PM as well.

I have been slowly working on the jack over the past several months, I have sandblasted and sprayed the main frame and stabilizer arms with primer. today I de-greased the hydraulic unit and stripped the paint off of it. I also have a rebuild kit and a place to supply the correct paint color for the jack. Hopefully I will have a finished product in the next couple of months.

I am finally getting close to finishing this project. I got the frame painted a month ago and painted the handle and saddle today. Overall it is turning out nice besides the poor paint adhesion issues I had with the jack frame. I believe it was caused by my use of self etching primer and my failure to paint it right after the primer dried. I am planning on using the jack though so I am not going to worry too much. I also have had some issues with the jack leaking some after I rebuilt it. I did not use jack oil and instead used John Deere Hy-Guard hydraulic oil I had on hand could this be the issue?

Paulsomlo I sent you a PM regarding the caster you have let me know if you still have it.

Saddle is done and the handle is almost done the only thing I have left is one more coat on the main frame.

Sent you a PM back - still have it and your's for the cost of shipping. You want just the wheel, yes? Not the frame, which is pretty much worn out anyway.

Here's that drawing on the Bassick caster, along with a picture of the Bond caster, as well as one on a Milwaukee jack. The wheels on the Milwaukee are not painted black. The Bond PN is 152-J-25-SP.

Got my new casters today and discovered a small problem. The caster arms on the jack are slightly cupped and the top plate on the new Bond casters I purchased are quite a bit larger than the old Bassick casters. Because of this the caster stems do not go in the casting as far and the holes that the roll pins go into do not line up with the groove in the stem. What is my best course of action? I am considering either modifying the groove in the stem or trying to modify my jack so the casters are retained with set screws like the new models.
In the photo you can see where the roll pin hits the stem

Yikes - I didn't realize that they had used roll pins.

I'm guessing that the later ones used a cone point set screw. I would try to determine where the center line of the groove sits in relation to the hole in the caster arm, to determine where the point of a set screw would fall. If it falls anywhere within the v groove, I might drill/tap for the set screw.

It just occurred to me - is the roll pin offset from the center line of the stem, so as to pass by the groove tangentially? Otherwise, I can't see how you would remove the roll pin, unless the old casters had a through hole in the stem.

Looking at the picture again, that's not a roll pin, it's a dowel pin. How are you getting that dowel pin out? Is it that loose?

At any rate, the retention on the caster stem I guess is only there to keep the caster from falling out when the jack leaves the ground.
