Thank you for taking the time to help people. I was having steering,lift and tramission gears grinding when shifting on a 2555 that l bought new n 1990. I removed the bypass valve and it was corroded. Cleaned it up and everything is working great. Your my hero.

Lance--Thanks so much for posting this and for the great details. Due to this video, I got the knowledge (and guts) to tackle this myself. I did find crud in the valve, but not too much, and it gave me the mojo to go on and tackle two more valves, the Low Pressure Relief Valve (right next to the brake valve--seemed ok) and the Pressure Control Valve leading to the brake valve which had a disintegrated O ring. I use the Operators Manual and Parts Catalogue for the 2020 as a guide since it is all I can find, but there do seem to be some slight configuration differences here and there. Information on the John Deere 1640 is pretty scarce, so your video project is great. We are having some very weird hydraulic problems on the 1640, so I thought I would start with the "cheap stuff" first--the filters and the valves you can get to from the outside before taking the dreaded top off. Cheers, Jim Stewart, New Brunswick, Canada

Great work Lance. Good points i had a guy out west spent $1000s on parts and he called me saying he has done everything ,it told him to grab a 1 1/4 and pointed pliers and he called back to say the roll pin had failed.

You helped me fix my 2555 and thank you. One tip l had already changed my oil and filters and didn't want to drain all the oil out. I back the tractor up on an 8" block and removed the bypass valve with out spilling hardly any oil. Also l used a brass 40 caliber muzzle loader bore brush in a drill to remove the crud. Thank you for your help.

Worked like a charm!! Made my day and made my hydraulic problem go away. Many Thanks! Keep up the good work!

Had a Deere 2350 we just changed the hydraulic oil and filter in because of no hydraulics. I took your advice and checked this valve and found part of the roll pin broke and the piece was holding the valve open. I cleaned and installed a new roll pin and everything works great. Thank you for this video!

Used a bit of your advice yesterday - couldn't get plug out in front of my hydraulic filter screen and penetrating oil had no effect. Gave it a few sharp raps with hammer and opened right up. Thanks!

Thanks for the hydraulic lesson. I learn best by hands on doing it but your videos are about as good.

G Day Lance very handy tip for anyone that has one of these tractors 👍

Bundy bear, wow am I glad I stumbled on your channel I will pass it on. ‼️I went through comments and also learned much‼️ it was especially impressive to see you reply to all ‼️ well done be blessed From north Michigan

Love your knowledge on these Mannheim tractors

Well done, simple to the point. I just experienced identical issue with 301. Will try it, if it corrects issues I want to donate to your channel

Thank you from northern wisconsin 👍 very informative

Great Stuff! "Waving a hand" at ya from Grass Valley, California!

Why thank you very much from Louisianas swamp and bayous , Abita Springs, La

Good afternoon! Congratulations on the videos! I need your help! I have a 1640 john deere tractor. Hydraulic problem. There is no oil in the oil cooler and in the reservoir. He only raises a big turn. Vibrate a steering. Where do I measure the transmission pompe pressure Thank you for your answer in advance

Great details in this video.

Thanks for the video lance. I have 3130, When I removed this valve, it was a little different like you mentioned-my question is how much pressure or torque should the bolt pushing against the spring have? Cause right now there isn’t any, the spring & plunger just slide end to end, with that centre bolt in tight... thanks

I have a 5200 that the trans/hydraulics are getting hot. Checked the mesh screen and was clear. Only seems to get hot when PTO is engaged and have not had any trouble while tramming the tractor.

Great video Lance; I have a question about my jd 2020. Can you change the impute shaft seal from the bell housing side or do you have to split further.. Thanks in advance I loved the steering and front end video's you did. Thanks Rick

Great video hope this is my fix. I believe my hydraulic pressure is spiking. Cracked two filter housing in a row with Pto engaged on my JD 2555

Lance, thank you for the video. I'm struggling with hydraulics in similar tractor and your help makes a change in my understanding of the circuit. Suppose, a bypass valve with broken off fingers rotates in the seat. Can it lead to any crack in the line before the filter if the filter gets terribly packed with debris? Do you know what oil pressure should be in charge line of JD 2040s?

Aside from flush, filters and new oil, do you have any recommendations for troubleshooting a 1970 3120 with rear 3pt lift arms not lifting?

So you talk about the lugs being broke off the end of the valve which is what I found on my 2550. Will this make slow rear lift and hard steering or will the valve still work with them missing? Thanks

Quick question: I have a JD 2940 and was wondering if I can put the bypass valve in wrong? I am still having hydraulic issues. When I put the valve in I spun it around but never heard or felt it lock in. Once I installed it, I could spin it around some but not all the way around. My hydraulics still don't work after a couple of minutes. Thanks, Gary

Hi , from saskatchewan Canada. I very successfully used one of your videos to repair the steering valve on my jd 300 loader tractor after it sitting for 6 years , but now after the downtime the hydraulic pump is leaking . It has the big pump ( i think 23 gpm or something like that) are you going to do a video on rebuilding these pumps ?

hi there i have 6320 transmission heat oil light coming on when doing road work after about 40 minutes driving . i have blowing out the rad with compressor have check fan clutch tested themostat for transmission . filters and oil only changed 400hrs ago . next step is to take radiator out and test if engine coolant is mixing with transmission side of radiator. anything you recommend to check thanks luke

What is the valve that’s on top of the priority valve for the hydrostatic steering called?

Hey Lance I have a question regarding my 4440JD? I was bedding pens in our feedlot and all of a sudden it wouldn’t go forward. It wants to go forward but couldn’t. Then I kicked in my PTO and my tractor would move. Does this sound like a clutch problem not getting enough oil or a valve not working properly? Or is my clutch just gone? Thanks!

friend I have problems in the direction it is very tough and the plow does not lift either, which could be a Jhon Deere 2850

I bought and just installed a rebuilt high pressure pump in my 1830 jd but the loader is very slow and the steering seems to not be getting enough oil either. To get increased flow/pressure will turning the adjusting mechanism on the pump do the trick or is there something else? I verified there is excellent charge pressure coming to pump. also the old pump i took out had alot of pressure but i replaced it becasue it was pounding and cracked the high pressure output line which goes to the priority valve.

Thanks a lot for a very informative video. I have a curious problem on a JD5820 with milky or foamy oil in the transmission and struggling lifting power on the FEL. I thought it was water in the oil and have changed the lot including filter and cleaned suction screen however no difference. I do know if the 5820 has this bypass valve but I am leaning toward something bypassing and aerating the oil. After it has been left the oil clears up. Any ideas to check next would be appreciated. Thanks for your videos 👍

Better late than never, I do appreciate the video. The rockshaft valve on my 2240 is sticking or bypassing ???, the lever or the rockshaft will not stay down. Do you have a video working on this valve or the rockshaft control area? Thanks from Montana.

Hello, im from sweden i have a john deere 2040s, The front pump won't get any oil from the transmission, The filtrers are new and also the front pump, can a bypass valve be the reason the transmission doenst get preassure? The liftarms went down so i guess its a inner leak, is it possible to get down there without lifting the cab?

on my JD 2020 i lost hydraulics. I removed the bottom hydraulic filter and started the engine. Not even a drip from the transmission pump. Would the filter bypass cause this? Also, i cant get the filter bypass valve out. It seems to be stuck in the tractor. Is there a tool to get this out if it is stuck? Thanks for the info.

I am having trouble getting the valve out of a 2750 it seems like it is stuck the roll pin on the outside is broke any ideas on how to get it removed would be greatly appreciated.

my service book says to check spring compressed measurement. is that super critical? im playin with 300b hunting hydralic issue down myself.

I've got a 4440 with power shift. The hydraulics all work but the 3 point won't lift any weight. Will this valve cause that if it's not working properly?

Have you ever come across a deere 950 or with the turbo called the 1050? I'm still running mine and she's a brutal girl that never gives up and is far stronger than most new comparable new models

Hello lance, I have a problem with my hyrdaulics. I have already checked my filter everything is good. But the only main problem is the plow wont go down.

Helow Mr. Lance. I have a John Deere 2650, (Spanish made) recently replaced the orbitrol, changed oil and filters, cleaned the front Pump filter and the sump filter, all works fine except the hidraulic couplers.... Little pressure with high rpm. Can you give me some advice? Thanks you from Portugal!

Hi there i have jd2040 with sg2 cab,problem is that my rear lift arms are bit to high in lower position...when tractor is shut down arms are in lower position and when i turn it on it raises a bit....is there a way to adjust this? Sorry for my bad english

I seem to be into the same thing hope like hell it works

hi, good information… you are the best… in jd 3040 to remove the valve is nesessary to remove all hydraulic oil before? or can i remove valve unless remove oil?

We have a 3140 we have checked this valve changed both transmission pump and front pump but when the tractor heats up after running for about 15 minutes the rpm has to be high for the loader and steering to work we know there is a leak but do you have any tips on how to find out where or books or testers we can get this has been happening for quite a while .

Is the valve for the 4500 similar? Thanks much for your time sir...

Did they have mixed open center and closed center utility tractors over there too?

I have a 5525 john deere that my loader is working fine, the three point goes and down but drifts down when setting, it appears but my rear hydraulics are not working at all. I have changed the filter and fluid even though the filter looked clean and checked the screen. I cannot locate the Bypass valve on this machine . Even with diagram from John Deere. When starting the tractor it sound like a lot of hydraulic pressure is built up. The motor bogs down. Any idea. Would this valve be the issue or something much more costly?

I have a JD 540 4x4 tractor and the forward reverse shuttle has quit working,can you help me out with some troubleshooting.

Hello, you videos are great, very informative and I'm sure help hundreds if not thousands of people with their equipment. I recently purchased a John Deere model 510 and would like to install one or two sets of remotes at the rear immediately and a loader at some point in the near future. Can I use hydraulic pressure from the transmission pump or is the front mounted pump the best option? Thanks again for your videos, keep up the great work! From Ontario Canada

I have a 2130 series JD, I recently put a new rock shaft with new bushings, seals & shaft. When I fired her up the 3-point arms went full up and now won't lower!! Any input on this will be greatly appreciated. Thanks

Mr. Bundy. I have a 2130. The 3 point hitch does not stay up. It lifts and then starts drooping down. If i give it some revs, the hitch comes back up. If I use the remote hydraulics, the hitch just comes down also. The steering of the tractor is also spungy and hard. I will check this bypass valve and filter now. But I doubt that it is it. Because I bought the tactor from a mechanic who changed the filters and oil.

Could malfunctioning of this valve cause sufficient pressure buildup in the filter housing to blow hydraulic fluid out past the filter housing o-ring/gasket?

Have a problem with my John Deere 3350 my steering is gone hard and can’t move and my link arms won’t go up or down but my brakes are grand any ideas?

I just bought a John Deere 2020 1967 it has no downtilt pressure on the bucket and no down pressure with the arms to lift the front tires. It will pick up a load of manure and dump it. But down till it won’t even extend the cylinders all the way. And the arms will not lift the front of the tractor off the ground. Any suggestions? Thank you

how do i get the air out of my hydraulic line on a 1020 john deere,hydraulics go down 1/3

How loose should the valve be in the bore, mine is pretty slack fit and will move a few millimeters side to side?

Hello Lanz. My name is Alexander, I'm from Ukraine. you shoot very informative and useful videos for people. thank you very much! We have 2850, we have a problem - it pulls out the front oil pump seal. please tell me how to solve the problem. Thanks!!!

Do you know where this valve is located on 3040 Made in Germany Tractor ?

Does the transmission pump supply pressure to your wet lines

Hi, is the location of the filter bypass valve the same for a JD 2250 tractor? Thanks

Having problems with my John Deere 3350 my steering is gone hard and my link arms won’t go up nor down but my brakes are good anyone able to help?

My 1830 won't start when hot. Cold, just warm, no problems. Of course, easier when hydrolic arms are down. But when hot. It won't start. Have to wait it cools off. Any idea what's the problem. Batteries are good, the contact too, the starter is good also. Nobody can find the problem. Thanks.

Where is this located on the 4430? I found your other video testing one from a 30 series but haven’t located it on mine

El problema hidráulica que tengo jhon Deere 3140DT carcasas del filtro del transmisión fisuras ? Esa válvulas puede ser las causas ? Agradecería ayudarme . Saludos desde Paraguay

Hello, I'm sorry, I'm from Argentina. I have a 3350 that has problems with the hydraulics, the steering works very well. but the tool cylinder doesn't lift me up. I wanted to know what the problem might be. Thank you...

I have a john Deere 1040 that has no steering my 3pl arms don't lift and my hi/lo doesn't work I have cleaned the hydraulic screen put in a New filter and flushed the oil with new oil 3 times I can hear oil squirt in the hydraulic filler cap have you ever heard of this

When attempting to remove the valve, does the filter need to be removed as well to allow the valve to be pulled out?

Does John deere 4440 have a bypass valve Were is it located

Thanks ! 🤗😉

Do you think that the 2140 4x2 can be put 4x4?

Hi, thank for these videos, if you only know how much money your saving farmers around the globe! My question: 3130 suddenly lost steering and remotes. But pto work fine. No oil go from trans pump to front pump, where should I start troubleshooting?

hi ,i’m from italy, before remove the valve is necessary to renove all hydraulic oil?

Hello im from Albania and i have problem whith hydraulic and problem with the steering system im waiting your help

hi, I write from Italy. thanks for the many help / advice you give! I have a problem on my JD. The old owner was traveling without a transmission filter. During a full service I decided (rightly) to put it back. But with transmission filter, arms and steering do not work. As if no oil / pressure is coming. If I remove the filter, everything works. Could it be some enchanted valve? thank you

Came across your video trying to find out why I loose all hydraulic pressure like 3 point and steering on my jd 1120, I could run the tractor for a bit then all of a sudden no hydraulics, I shut it off let it sit for a minute or 2 they work again, level is full, seem every time i loose hydraulic I have to shut it off, could that be the hydraulic pump in the front be getting hot and weak? or this valve that you showed, and if you could tell me where to start looking that would be great any help will do

Magnifica esplicacion amigo

Amigo como va el sentido de la válvula yo tengo un 2030 hi me vaipasea el aceite gracias

Have hydraulic problems with john deere 2040.any one out there know anything thanks.

i put my bypass valve in without turning it i tightened the nut and now i cant get it back out. any ideas

What would cause hydralics not want to work when its cold out

what are the symptoms when that valve is not working properly?

I have a '74 full power shift john deere. Last winter I started it to plow snow but the shift lever wouldn't move. It acted like it was solid. Something gave and it now moves but I don't have any forward gears. Reverse is fine, hydraulics still work. What am I missing

1980 John Deere 950 3 point hitch is stuck in the up position any advice? Thank you for your time

Would that valve make my loader chatter when I raise the bucket if not what do u think it may be. Its full of clean john deere hyd trans oil and new filter what's ur thoughts

Sr what this tractor? What serial?

Much more complicated than a Massey Ferguson 188

Por favor en español soy de Ortega Tolima Colombia 😊
