Farmall MD: Rebuilding the Hydraulic "Lift-All" pump

Today I am rebuilding the Farmall MD hydraulic "Lift-All" pump. This is the same pump used on the Farmall H and gasoline M. I show how all the pieces of the pump go together, what to look for when rebuilding the pump, and how the pump & control valve work.

What a nice job. You are an outstanding teacher. I hope everyone in need is following this.

[@alanviner3711]

every video is like going back to school, you always walk away with more than you came in with..Thanks for the education...and have a great day

[@fordenginebuildersv8power184]

I’ve rebuilt many of those pumps through the years! You sir are a great instructor!

[@n.elliottnoorlun8304]

Pretty amazing how Farmall, even back in the 1930s, intended their tractors to last for decades by their fine engineering!!🤩🤩🤩

[@winchester37a]

* centuries

[@rogerschlitter5116]

I knew an IHC engineer who said when he started “we just built things so they wouldn’t break. Later on we had to reengineer parts if things didn’t break because that meant we had too much cost in the machine”. Theoretically you could build things that virtually would never fail, but no one could afford them.

[@richardanderson2742]

As always, a great tutorial. If you ever get tired of farming, any VOTECH center would love to have you teaching mechanics. Really good teachers are rare, so are really good mechanics. You are both. Knowing how things work is 50% of knowing how to fix them. You sir do a great job of explaining the basics.

[@ottoneidlinger4938]

@GeneSun this is so sad to read. A free teacher who wouldn’t demand days off, raises, healthcare, retirement. They should at least asked the kids to see how many would have signed up. I hope you are able to teach your kids the value of hard work. Good luck to you sir.

[@springhollerfarm8668]

@@1crazynordlander That sounds great except I get the feeling that Pete would prefer to not become attached to Mike simply because of all the political nonsense attached. I like Mike and bet Pete does, too but it's everyone else's political crap I wouldn't want to swim in and it just follows in today's world.

[@scrotiemcboogerballs1981]

Thanks Pete wonderful job on the pump and explanation of its functioning can’t wait to see it working again one step closer

[@frankrightbrain]

I’m effectively “in class” when you’re rebuilding something. I really enjoy these videos. Thanks Pete.

[@larrydavidson3402]

I sure understand a lot better how a hydraulic pump works. Thanks Pete.

[@donmears4090]

I like that the top of the gear housing isn't sealed by a gasket or plastic from a tube but good old fashioned craftsmanship!

[@msw00]

Great discussion on pump workings, keep getting her done, can't wait to see her bale hay!

[@MarkWYoung-ky4uc]

I like your thinking Mr. Pete. It's bullet proof and if properly maintained, will be around when these modern tractor lifts have been recycled into something else.

[@glenrummel4483]

The detail explanations of how all of the components work in that pump was over the top. It will be very interesting to see the finished Farmall MD. Can't wait. Thanks for all your hard work.

[@PaffordHomestead]

I think Pete has worked on everything 😂, very knowledgeable great job Pete ❣️

[@Dan-qy1rg]

Great explanation and step by step demo. Thanks for sharing, have a good week!

[@GWBoen]

Great video as always can’t wait for the next one

[@localcrew]

Great project. I look forward to seeing it back together.

[@jeanhutchinson6198]

Those black gloves are a good idea. Wish they'd had them back in the day when my Dad used to work on the tractor and the family car. He'd come in and have to scrub his hands with D&L cleaner! All these decades later, I can still smell D&L when I think of him coming in to wash up. Miss him every day.

[@tdkrei]

Nice work Pete and thanks for the explanation and function. Keep on smiling.

[@ericbunksvintagesportsman6311]

This is perhaps the most informative detailed mechanical video on the internet on tractors...I so love your attention to detail..thank you soo much for this. I learn alot and am inspired in my mechanical journey of learning..Thanks again!!!

[@dannyschrimsher6453]

I’m not mechanical but I enjoy watching your rebuilds. I help my grandkids with hay so I enjoy the farming part a little more. Keep up the great videos

[@billysmith6131]

Thank you for taking your time and sharing this with us, great assembly!!!

[@mikecorrado4971]

I love all of your videos, but this one fascinated me also. Thanks! 👍🏼

[@tonyjones1378]

I may not ever work on one but I enjoy watching thank you for all your great videos. I watch all of them. 👏🇺🇸

[@cherylirvin3919]

I will never do this but I watch anyway. I am amazed at how you can do this but even more amazed that someone figured out how to make the engine. My dad sold International Harvester products when I was a child. He would love this.

[@marcplaisted6511]

Thank you Pete, that was very informative and fun to watch you.

[@trevorscott5625]

Great detail as always Pete. Good deference piece for my rebuild of my Super A.

[@MartinP1214]

I learn something that I never knew I needed to know from all your videos. Keep up the great work!

[@dwcmaverick]

One of your best videos to date, this has been an excellent explanation of a Farmall hydraulic pump.

[@timlawson9370]

Hi Pete. Thank you for taking your time to share How things work

[@jimlong527]

Pete I think you know more than the manufacturer. Interesting. Thank you 😊

[@ellisc.foleyjr9778]

The Beauty of a good video is when it gets to the end you go "What? it's all over!!! naw Not yet!! I was enjoying this so much. > and yep that's what just happened and Im not a gear head either so an old man with a long memory of "In my day!" thanks for bringing back my day!. ECF

[@SuperMAZ007]

Very interesting engineering on the IH side with that hydraulic pump. Now all remains is paint and some tightly up later.

[@dalee.mccombs8571]

I really appreciate and enjoy your discussion about the theory of operation, hyd pump, transmission, carburetor, brakes, PTO, etc. I've learned so much. You're a fantastic teacher!!

[@cliffblackburn8102]

Great video Pete! Really liked that assembly 💯✌🏻💚👍🏻

[@MarkQuinnelly]

Good morning Pete! Thanks for sharing and making another great video!

[@jamesmorrison1884]

Great video Pete I can take it all apart I understand how it works. But I cant explain things "talk about it" how you do so well. I enjoyed this thanks. Have a great day.

[@dannywilsher4165]

I did enjoy the video tremendously. Though I will probably never build one of these hydraulic pumps, it was awesome to watch you do it. Who knows someday I may and someday I may not but I enjoyed watching you anyway. Thank you Sir.

[@KennyKizzleRustyNutzRanch]

One thing about these pumps that I haven't been able to find new from Case IH are those little spring retainers/check valve ball stops. There are other parts not available, but those darn spring retainers are such a small piece (you'd think they would be easily replicated). Great explanation of exactly how the pump works. When I did mine I tore it down and went through it. Never spent a ton of time REALLY thinking about how it worked. Thanks for a great explanation of actually HOW it works.

[@rhekman]

26:49 We run International Hy-Tran in my dad's 1948 Farmall H instead of the 30W oil IH originally called for. My dad got in that habit since the tractors on the farm would mix and match between implements, and we didn't want to contaminate different hydraulic oils between tractors from whatever remained in each remote cylinder. I think that's a pretty common practice among vintage Farmall owners. Now that the H is just a loader tractor, we added about a quart of Lucas Oil Stabilizer to the hydraulic system to help the pump stay lubed, build pressure, and slow down leaks. It seems to work pretty well.

[@mickeychaffinch6994]

Good to know. I am having a 1953 Super M rebuilt and want to use the same hydraulic fluid that my John Deere 2630 uses...just to keep all fluids the same.

[@johnmicallef9160]

John Andrew Micallef from Canada . I started to watch your show its good for all those who love farms specially who have no experience too and how you explain to fix machines you so good may the good lord bless you with all blessings , one think you never show if you have rabbits i love to watch rabbits and Goats .God bless you and your family always .from Canada

[@markfin7225]

I appreciate your attention to detail and explanations, well done.

[@ChrisSmith-io5vw]

Thank you Pete feel like I just went to tractor mechanics class I think you'd make a great teacher sir and that is a compliment I've never thought about how many parts was in a tractor I just always enjoyed driving even though I took Motors apart that's a different thing though keep it up enjoy the show much thank you so much sir

[@zodszoo]

Nice work sir, you're the definition of a Craftsman. 🖖✌️

[@justinwetzel681]

This was awesome Pete.

[@redbudfarm]

Thanks Pete! I now need to buy a Farmall and use all this knowledge to rebuild it 😁 Seriously, great video!

[@haroldhaugaard410]

I am so very impressed with your eclectic back round and your general knowledge of a wide variety of things, especially your understanding of engines. I really enjoy your videos and look forward to every one.

[@bobbygibson3586]

Mr. Pete thank you for explaining things the way you do. I Love your videos and I actually learn so much. Please keep passing the knowledge on. Thank You so much.

[@scottmcd5885]

Is it just me or does watching something like this relax you? Talking about torque... What always gets me is the 2 separate tables. One for dry torque and one for wet.

[@dnorthup65]

19:12 With all the yoke talk, I was hoping he'd add one of his eggcellent dad yokes in here . . . . like, "How do you know if the yoke is bad? . . . . The chicken never hatches."

[@waynemacquarrie9833]

Pete has a calming voice so relaxing,exlent instructor.

[@singleman1986]

Yep. We've been 'upgrading' the older Harley Davidson cases with that sanding method for the last 40 years. No more 'marking its parking spot'. Previously, we could tell when we were out of oil when there was no oil spot on the ground. LOL. I 'specialize' in pre-'65 Ford tractors but your attention to detail is quite admirable. I'm 'hooked'. Best of success and God Bless...~Eli.

[@geneprepchuk3819]

love your videos Pete so informative, I like the way you interact with all of your animals, you are a caring farmer God bless you and your family and all of your animals

[@darrellgambrell371]

Rebuilt Ford 3 spd transmission on 60's Falcons. Used a 12" piece of garded hose of same dia. of shaft, to install needle bearings. Simple to do, then use the saft to push out the section of hose, and your done.

[@tommicks53]

Complicated but still simple. Thanks Pete for your clear details and explanation about the pump assembly.

[@richyoung5007]

I am going to rebuild my live pump on my 1953 Farmall M and so I like the explanation on how the pump works. I like how you lapped the seats for the ball bearings.

[@tokencivilian8507]

Great job explaining how that system works as you went through it. Love your channel and I'm looking forward to spring and hearing about your next batch of chickens.

[@stephengordon8968]

What an informative video very nicely done !

[@annbarron5874]

Wonderful teacher, sharing knowledge in so many areas. Thank you.

[@dankreoger611]

I enjoy this. My moms dad was a mechanic for the local IH dealer back in 40's and 50's.he passed in 64 when I was 5. Gives me a idea of what he worked on. Funny thing about him that I do remember. He could put his fingers on the spark plugs and stop the engine.

[@Wheelloader__]

Awesome video Pete. I’m a little smarter with each video.

[@barryluther6811]

My old boss man, from Western Auto years ago, would place his sandpaper on a piece of glass when sanding weedeater carburators. He always said the glass was smoother than any work bench top. He was right and it never failed him.

[@RatdogDRB]

Lookin' good there Pete. Always enjoy these videos of how things work while doing the rebuild on 'em. Keep warm and dry.

[@jeffreyjohnson8212]

Great job Pete.. thanks for bringing us all along. She is gonna be Sweet!!!

[@jamesweaver4021]

I’m not sure how long I’ve been subscribed but I realized recently that you’re the “Mr. Rogers” of farming vids. You have a gentle nature that shines through and is captivating. Thank you for doing what you do and how you go about doing it. I restore little Jd “tractors” 110,112,120,140 from the 60’s and 70’s. It all started with replacing an oil seal on the front of a k321 engine in my greeat grmpas 72 140. Good stuff sir, ty.

[@paulmcmullen9533]

Love this channel. Your knowledge of rebuilds is astounding. I love the lecture style guide-through as you work!

[@jalpa9642]

Thanks Pete....! I remember those Needle Bearings very well, in Automotive School-Transmissions-Automatic/Manual, Manual shift Class, we tore down a Standard 4-5 Speed Tranny. Way down in the very bottom of the Trans Case is a "Cluster Gear"... it's stationary but it messes w/top side gears and it spins on a Shaft. Dismantling all the innards.... the Cluster Gear was last or next to last(can't rightly remember this was back in the 70's) and I'm 72....! The center of the Cluster Gear was hollow, the Shaft went through the Center but there were "Needle Bearings" that had to be inserted inside the Hollow Cluster Gear housing w/thick grease. The Case had a hole and you'd put the Cluster Gear down inside the Case, line up the Shaft holes in the case and slide the shaft into the case and the Cluster Gear at the same time.... hoping that all the "Needle Bearings didn't come out the other end.....! What a chore that was...! =)

[@springhollerfarm8668]

As usual, very well done. Everything was thoroughly explained so I fully understand how it works. I found the mechanics of how they did it back then in such a simple way fascinating.

Great job of explaining how the hydraulic pump works and steps to take to improve operation. Information that I can use. Thanks much Pete.

[@fion1flatout]

I'd suggest going on tour giving talks, as soon as your kids can run the farm. I think you small farmers will save the planet and our sanity.

[@warrenvalentino5763]

what a Good way to start the day, watching one of your Great videos! :) :)

[@johnnyholland8765]

I have worked with hydraulic valves pumps and actuators for the aircraft industry for years and it is amazing how they are all similar in how they operate. Lot of new technology but they all operate on the basic principles of pressure, relief , bypass, return pressure etc...

[@steveeab2364]

Absolutely amazing to see the engineering on these. It's crazy the advancements it technology since engines and the automobile was invented. Looking at history before that, thousands of years of what seems to be very slow progression.

[@sweetpigfarm3645]

How you did that with the float glass is how I was taught. I have used this when rebuilding mechanical pop injectors. I was told to use a figure eight to keep it even. This tractor is going to turn out nice!

[@lincsfencingandgardeningse9128]

Allways enjoy watching and listening 😁

[@leonardcrane6689]

Very informative and explanation of how it all works is top notch thankyou Pete.

[@cambian3]

Great video! I just finished an 8N (1947) hyd pump. Easy, old fashion, and works very well. Rated at 800 lbs of lift. It does pick up the 5 ft. Modern brush hog (810 lbs.) Thanks for the info I may need one day.

[@fbh31118]

Last piece that needs to be rebuilt on my H. Great information Pete!

[@lbfishin2156]

Excellent jo of explaining! I was able to follow you though the whole assembly!! you make a great teacher/mechanic!

[@davidschlecht3016]

Pete, you said that the pump system is pretty basic and simple and I'll take your word on it, and is interesting how well the system worked. Maybe in your next update you can explain how a live hydraulic system worked differently so when you stepped the clutch you still had the power,and if that tie in gave you live pro. Thanks for Avery interesting video on this part of the MIGHTY MD.

[@tommybounds3220]

Your talk about all of the details is awesome!

[@mikemorris4952]

heh, and just remember, this all pre-dates computer design etc, what good engineering!

[@geneard639]

Best thing about old school? Don't have to wait 6 weeks for a tech to show up, and the first thing they say is 'have you tried turning it off and back on again' followed by "that will be $600".

[@chadklingshirn1508]

Nice work Pete!! Keep it up! We enjoy the knowledge you share here at the Big K Ranch. I'll send up my M and let you redo it one of these winters. Lol

[@jaasx]

Another great video on the Farmall. One technical quibble - the gear pump doesn't compress anything. It simply produces flow. The rotation moves flow from one side to the other (inlet to discharge) and provides a seal between the two. Any pressurization is due to downstream restrictions and the flow trying to go through them. This is true of any positive displacement pump (piston, gear, vane). A dynamic pump (impeller) does actually produce pressure. And oil isn't compressed, it is pressurized. (Oil being incompressible for all practical purposes.) Gases compress. (Ok, If you want to be really technical, there can be a small amount of oil compression where the gears mesh when the fluid is trapped between teeth.)

[@donvoll2580]

Good day jjabbxs I think that is why air is use if u want it too compress. Someone told me something like that. Thanks

[@tommcmillan3143]

Excellent work Pete! Thank you for going through the theory of operation, we have a lift-all on our H and I really didn't know how it worked or what the specs were. Very informative!
