So my hydraulic pump leaks on my WD45 and I was thinking that I would find some one to take it apart and put all new seals in it while I have it off then I do not have to spend all that time looking around to see where it is coming from. The pump works good nothing wrong with it othe than it leaks I can not find any one that has done that befor .. Yalked to two Agco dealer they did not sound very confident and they charge $109 an hour. My question is can you guy recommend someone to do that job and what a fair price would be? ? Also is this a bad or good idea to do this??? I live in Monroe WI Thank you for your time Hope you have a great day |

Aaron, Ted is right Sandy Lake would rebuild it or they have refurbished ones on the shelf too. Other suppliers may have them for you also? It takes me several hours, ok days, to go through one. It just takes some time and patience, and a good exploded part diagram too.

| Have you tried to determine where the leak is? Mine was leaking badly. I cleaned it up good with pressure washer and then gasoline. Turns out was all coming from one spot at top rear at a plug. Took out the plug and copper washer. You could see where it was leaking past the washer. Replaced it with an aluminum oil drain plug washer that happened to fit. Bone dry now!! I don’t know how long it will last as aluminum is soft but so far so good. I use the hydraulics lots with my carryall. |

Ed has a good suggestion! Always good to see if you can locate the leak. Might just need to snug up some fasteners?

| Forgot to mention. Previous to this I had replaced both hydraulic hoses. Top one was seeping a bit so I replaced both. Figured after 65 years was time to retire them. |

They are more of a pain to remove and reinstall than to actually tear down. If you do want to try to disassemble the pump yourself, it isn't that tough but there are certain things you have to know. First get a good repair book, an Allis one not I&T......Have a parts diagram which the Allis service manual should contain, clean the pump extremely well before disassembly, you need a clean cake pan filled with clean diesel fuel to place parts in. Place the parts in the exact order they came out and do it in a manner so you can see how to put it back together in the right order. Swapping spools and other parts just because they look the same and have the same part number is a no no. Some of these parts are individually fit to there bores at the factory. Don't mess the parts around! Do this job in a place where the parts won't be disturbed. If you do all that it is pretty simple. I'd replace every spring for sure besides all the seals and o-rings. They are inexpensive parts. One or two seals require removing a lever that I think is held by a small roll pin if I remember correctly..... it's been a while. It's not that tough of a job if you just keep on it and don't set it aside to come back to weeks later. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

My Dad worked for Allis from 1954 till into the 90's as a service rep. Watched him tear down several WD 45 and D17 pumps for friends after he retired. I have only tackled 2 myself since he passed on but they worked out. You can DIY but be slow and careful and CLEAN.AGCO still have the parts. |

Agree with the other guys as it is not a hard job but you need to keep the parts in order and not get in a hurry and rush through it. I also recommend replacing all the springs, o-rings and seals while it is apart. Take plenty of pictures of how the pump mounts and any linkages that connect to it. ------------- 1957 WD45 dad's first AC 1968 one-seventy 1956 F40 Ferguson |

Depending on how much it is leaking, you can always just pour a little more oil in and keep going. It all depends on how much it is leaking ------------- We the unwilling Led by the unqualified Doing the impossible for the Ungrateful |

| I like kerosene in place of diesel. I feel like it cleans and drys better. Either one works. Leon |

| Is there any special tools I should get to make the job easier? ? |

| Two nails of the correct size with the pointed ends hammered flat to hold the rollers depressed slightly to make installing the pump easier without tearing the new mounting gasket. Once the pump is in position, pull the nails up and out and push the pump in towards the clutch shaft. |

You must be good Doc. It takes 4 nails on mine. You must double up...i'll have to check into that. No Aaron you don't need any special anything. The most critical part would be to keep everything in correct order front to back on those pumping sleeves and the valve that's inside them along with the shim spring washers. Originally I think the valve was fitted to each sleeve but probably don't matter so much 60yrs later. The book says keep together. That is a straight bore and can all be pushed out together in a row. The sleeves face one direction ,won't work reversed. In my experience,getting the orings on the unloader valve past the oil ports without nicking them is the hardest part.

Did you check with Bartel's Sandblasting in Monroe? If they can't do it Nick might know someone local that can! ------------- D14, D17, 5020, 612H, CASE 446 |

Thank you for the tips every one. Also is there a reason I can not use simple green to clean the hydraulic pump? ?and I am going to be rebuilding my Carburetor also. I would think using simple green on both of those? and simple green it is not flammable like fuel is.. I am going to be by a wood burner in the shop.. |

| The wood burner can be fun. I was cleaning parts with 1/2 gallon of gas 20 feet from the wood burner. I saw the fire come across the floor and light up my parts while I was cleaning. It started me on fire also. That's another story you don't tell Dad. |

Aaron, I cant think of any special tools required. Lon's story of the gas fire could be tragic. I would stay with the simple green idea. That sounds safer near the wood burner! Large clean area, maybe a big bakers tray. lots of pictures as you take it apart. a good service manual. See if I can find some pictures Maybe they will help? I apologize ahead if this is to much of a picture dump. And also when I took these the camera lens was not clean and a lot are blurry. Not my best work. The assembly of levers to get to the two side shaft seals was the hardest for my old brain! These are in no order. I did this with the frame off the tractor so have not had install issues. But I like the zip tie idea! For sure these are not all the details of working on one of these units. You can do this! Its only nuts, bolts o-rings, springs, and gizmos!

Thank you so much for the pictures. Brings back some GREAT MEMORIES of working on the WD - WD45 pump. Listen closely to all the suggestions above. Also, you may contact Sandy Lake and get the parts and if you do not have it a real good Allis Chalmers or AGCO book showing an exploded picture. I think the worst time I pulled and went through a pump was on a cold winter's day outside. Got the job done but I thought my fingers would fall off. Good Luck! Bill Long
