I had a Johnson Workhorse number 10 loader and it came with factory brackets for a wideframe. Bolted right up to my 129 without mods. Pump ran off the back of the motor. It had 2 front cylinders and IIRC, they were under the frame. Don't think I have any pics. They were on the old puter and the cub/loader combo is long gone. It was all factory.

Post some more pics of the pump. Looks like a vane pump from the pic you posted. In your pic it looks like it turns clockwise as it is sitting in the pic. But, some more pics would make that determination easier.

Who is "they"? Post pics of the numbers too. They should be stamped into the body of the pump, or on a tag. On that old of a pump, probably stamped.

The numbers stamped into the body of the pump are 294NO or N0. I cannot tell if it is a zero or an O or maybe a D. "They" are the tech people at Eaton Hydraulic pump company and they could not have had any less interest in my question. I have part of a manual and in it says that for a CC the pump is 5 HBCCW 5 AND ALL OTHER TRACTORS ARE 5 HB 5. I do not know what model or make of tractor this unit came from. I do not think it was a CC. That would lead me to believe that it is a CW rotation pump. The intake port is bigger than the output port as you can see.

Ok. Wanted to get back to this. I have dug, and dug.... I have a hydraulic shop that I work with all the time. They are the best people I have ever found at what they do. They and I neither one can identify this pump. Nor the maker, but we are almost 100% certain that it is NOT an EATON pump. Now, it may be that the maker of the pump was bought out by EATON, but it wasn't made by them. If by a long shot it was, they and I neither one have ever seen an EATON pump like that. The numbers you are using on the housing are nothing more than casting numbers. They'll get you nowhere. There should be, somewhere, a number stamped, not cast, in the housing.

Now, we also aren't sure if this is an odd gear pump, or what. But my hydraulics guys and I agree that it looks like a vane pump.

As far as direction of rotation, put your hand over the suction port and turn the pump. When you feel it suck, that's the direction it turns. May have to put oil in it to seal the pump enough to suck turning it by hand.

If you want to know more about this pump, we recommend you take it apart. Not sure if this info helps, but it's all I can come up with without numbers and seeing the inside.

Jonathan, I appreciate your effort on identifying this pump and here is some more info on it. The word EATON is cast into the pump housing and not stamped. On a bolt head, about 11/4 inch wide, next to the high pressure port is stamped L G with the numbers 12170-5 below it and next to the low pressure port, on a bolt head about one inch wide, is the letter C that is underlined. There are no other markings on the pump except the ones that you can see in the picture. There is a little symbol and then covered with the white dye the letter 1.

[J-Mech]

Is the bolt head that has EATON on it a relief valve? Or did you mean it says EATON on the actual pump housing? Sorry I'm not sure what you meant.....

That symbol on the housing has a rackin our brain. Looks familiar, but it's not an EATON symbol....

[inspectorudy]

The word EATON is cast in the pump housing and the numbers on the bolt heads are all stamped.

[J-Mech]

Wow. My hydraulic guys and I both would have put $100 bucks that that wasn't an Eaton pump. Never seen anything like it built by Eaton.

Now, are these two things the same part? Your pics are great, I'm just having trouble picturing this as a 3D unit.

No they are not the same part. The hex bolt with the numbers on it is just visible behind the port outlet that you have circled. There is also another one by the other port with the underlined C. To me they look like they may have been alternative port openings for larger size outlets at each port location and that these are just hole plugs. If you go up to my three picture set and look at the one in the middle that is the large numbered hex bolt and the high pressure port next to it on the bottom of the picture. And the low pressure port is visible too, on the top side of the picture, with the smaller hex head bolt with the underlined C, next to it.

HOLY FREAKING CRAP I FOUND IT!!!!

That sir, is a power steering pump off a Studebaker!!!!

That big thing that has the numbers, is the pressure regulator valve.

Check this out Rudy! .......... Studebaker Ps Pump
