MF20 IND Power Steering Pump

rickf1985 · Aug 12, 2020

I have a 1970 MF20 Industrial with the Perkins diesel and the power steering pump is finally going out I believe. I cannot find a replacement to save my life for the one that is on there. I have found several replacements, I believe they are Barnes pumps. The pump that is on there is a Plessy. Can anyone tell me for sure that the replacement pumps will fit? And has anyone done this swap and can you tell me if the lines were even close or do I need to have custom lines made?

I tried to link to the replacement pump for reference but it will not let me? It is a 773126M92

Before tractor serial number 9A132003, power steering pump part number 527904M91.

After tractor serial number 9A132003 to tractor serial number 9A143879, power steering part number 888744M93 (old power steering pump part number 888744M92).

After tractor serial number 9A143879, power steering pump part number 888744M93.

This is according to the AGCO (MF) online parts book for the MF20 industrial tractor.

Thanks, but this info is only for the original style pump which is unobtainium. Unless you find one in very used condition which I do not want to do, I already have one of them on there. I am interested in the ones being sold as replacements and apparently the ones that were used on these units as stock in most cases from the pictures I can find. It is a Barnes style pump. It is shown in the store here as part number 773126M92

OK, So here is my original question copied from the original post, Nobody has answered it yet so I am going to assume nobody knows. [color=red:9a18d093b3]Can anyone tell me for sure that the replacement pumps will fit? And has anyone done this swap and can you tell me if the lines were even close or do I need to have custom lines made?[/color:9a18d093b3]
I have looked through my parts book and they show the Barnes pump for that tractor in that year. I am going to go on the assumption that the pumps that are advertised will work and I will just have to work around the lines when I get it. I appreciate the answers and the time taken to answer but it would be a lot easier if people would read the original post and answer the questions that were asked. I know where I can get the aftermarket pumps, They sell them right here on this site. I do not want to try to put on a used Plessy pump that can be had for 250.00!!!!!!! That is just crazy. I just wanted to know if anyone had done this, or has a 135 or 20 with the Barnes style pump on it that they could take some pictures of the lines for me.

I've never worked on a tractor that had the Plessy pump, nor have I done the swap, but looking at the parts book I'd say you will need the lines, and the fittings that hook the lines to the pump. https://na.apb.agcocorp.com/p/masseyferguson/651281/l/134?

The link just takes me to a header that say AGCP partsbook.com. Nothing else, just that.

Thank you, THAT is what I have been looking for!!! I need to figure out how to get into that parts book. It would apparently make my life a lot easier.

The AGCOparts.com site doesn't let one make direct links to a given page or catalog, from my past experiences with it. Here is a link to the AGCO parts site. https://apb.agcocorp.com/ This p...stractors.com/photos/mvphoto60282.jpg[/img]
