Hydraulic Pump
Hi I was wondering what a 1971 Case 442 has for a pump and what are people replacing them with? Thanks hwcase 442

Hold up there BG.....
Some of the early 444 and 442 models apparently used the A-body pump. The OP needs to check which one he has prior to ordering.
Page 3 of this manual that is found in our Tech Library/Service Manuals/learning about hydraulics tells the story.

There is about an inch difference across the centres of the mounting bolt holes between the small AA style and the larger A style pump. Armed with that information, determination should be easy. At that point, the suggestions in the FAQ "Where to buy STUFF" can be investigated.

Welcome to the site HW Case 442. Also make sure you get the correct rotation on the hydraulic pump.

Yep, I have a PK442 and PK222 that both have the older A style pump. They are both Borg Warners..... Nice new photo Hilda!! :trink:
A chassis s/n would quickly pin down which pump mounting was needed!

That was what I was getting at. Have him post the PIN, direct him to the parts manual, find out what is supposed to be there, then have him check it out to be sure.myerslawnandgarden said:A chassis s/n would quickly pin down which pump mounting was needed!

Hi the serial #9633623 and it has a parker pump on it not a 100% sure on year Thanks Harry
If you consult this manual ................http://www.manuals.casecoltingersoll.co ... marked.pdf from our Tech Library, Page 38 shows the pump but Page 39 tells you that the 442's AFTER PIN 9632452 used the same pump as the 220 and 222. That would be the Double A Parker pump, not the Single A pump that is equal to the Haldex Barnes 4F667 sold by Grainger's.
Go to ............http://www.phionline.com/ click on "hydraulics" on the left side of your screen. Then click on "pumps" and then "gear pumps". The last pump in the D Series is the one you want.
You may have to obtain an O-ring fitting for the INLET side of the pump if you have an OEM pump with the press-in formed fitting. PHI has been down this road in the past with other people I have sent to them. Tell them it's for a Case garden tractor and that you need a 90 degree fitting for the inlet that will accept a hydraulic suction hose.

Maybe I am reading the phi chart wrong but there is a note that all the D series are capable of 2500 psi EXCEPT the last one (D27) which can only accommodate 1500 psi, is this pump still an acceptable replacement?
Yes.
Had you gone into the FAQ, "where to buy stuff" as was suggested earlier on in your thread, you would have seen a notice that explained that. I'm not trying to be difficult here but the FAQ's were written for good reason. :thumbsup:
If you look at my Avatar, you will see that I am smiling nicely as I say this to you. :sidelaugh:
However............when in doubt.... you should always ask. There are no dumb questions on this site.

Aahh, my mistake was clicking the link you posted above BEFORE reading AND remembering all the FAQ's. It is SOOOOO much nicer dealing with people who constantly smile! :thumbsup:
That link was just to help you determine which pump body-style you had in your tractor. It is always wise to check the dimension across the mounting bolts because you never know when some previous owner made changes to the tractor. The last thing you need in your hands is the WRONG pump. RIGHT? :lol:
