How to Check Your John Deere Filter Bypass Valve
ฝัง
- เผยแพร่เมื่อ 25 ก.พ. 2019
- A lot of hydraulic problems are caused by blocked filters and in turn jammed or broken filter bypass valves. This video runs through how to check your transmission filter bypass valve on our John Deere 1640 Utility tractor.
Hello Im Lance (aka Bundy Bear) and doing these videos is my hobby. I do own Queensland Tractor Spares in Australia where I sell parts and offer technical advise to customers.
Parts seen in our videos can be purchased from www.queenslandtractorspares.co...
We have a lot more than we can offer on our web site available to us and in our store. If you dont see what you would like please email info@queenslandtractorspares.com.au and we will help where we can.
I do try and help with technical advise at bundybearsshed@gmail.com if you have a question or are having trouble with your project.
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.
Great to hear!
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.
Changing the filter usually only loses around 3 liters of oil and with the bypass valve being higher up the side it doesnt lose much either.
@@BundyBearsShed Buenos día maestro leí tu respuesta a mí pregunta muchas gracias
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.
Yes the roll pin is quite a common problem.
I cleaned the Crud out of my valve, and bam! It works!! I would love to buy you a 6 pack. Let me know how to get you some $!!!
That is good news for sure, make sure you fit a new filter. buymeacoffee.com/bundybearsshed
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

Welcome aboard!
@@BundyBearsShed are familiar with the 301 industrial? Great running just retired bought it, changed fluid ran a day fine then hydraulic quit 😟
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
Just go slow and you will probably learn a lot.
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
Did it work?
Worked like a charm!! Made my day and made my hydraulic problem go away. Many Thanks! Keep up the good work!
Glad it helped!
Thanks for the hydraulic lesson. I learn best by hands on doing it but your videos are about as good.
G Day Robby, Thanks, this is how I earned my living for around 40 years. Doing the job and chatting while you go is the hard bit at times, stay tuned there is a heap to go with this tractor.
I guess Im randomly asking but does someone know a method to log back into an instagram account?
I stupidly lost my account password. I love any help you can offer me!
@Dakota Jad instablaster =)
@Adrien Caleb i really appreciate your reply. I found the site through google and Im waiting for the hacking stuff now.
I see it takes a while so I will reply here later when my account password hopefully is recovered.
@Adrien Caleb it did the trick and I finally got access to my account again. I am so happy!
Thanks so much you saved my account :D
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!
Glad it helped, thats why I do the videos, so people can have a go themselves. Good work!
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!
Glad it helped
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
filter housing cracking might be a sign of too much oil returned from a loader or similar.
@@BundyBearsShed buenas tardes te escribo por tu comentario sobre la caja del filtro hidráulica fisura yo tengo el mismo problema de un jhon Deere 3041dt si puede ayudarme ayudarme

Why thank you very much from Louisianas swamp and bayous , Abita Springs, La
Thanks Darren.
G Day Lance very handy tip for anyone that has one of these tractors 👍
This tip will save a lot of money if it is followed.
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.
No tool for the bypass valve, The oil goes from the screen to the trans pump then back to the filter. With no filter you should have flow. You may have a faulty trans pump. I have seen the gears crack on them.
Love your knowledge on these Mannheim tractors
My bread and butter for many years.
I just got a JD5403 and after a few hours use it started "bumping" while steering and while lifting the bucket. just started so the tractor is down. Do you think it could by that bypass valve??? Great Video.
I think the 5403 may have a different setup.
@@BundyBearsShed probably. TY
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
on the side of the gear shifter cover, the front plug.
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
No not on the 40 series.
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!
Does it work ok at low rpm but loose flow at high rpm or have no pressure all of the time?
@@BundyBearsShed no pressure at all.... Checked the filter by-pass valve, now its ok, i Will check the relief valve tomorrow...
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?
Test the pressure in the shift cover it is the front plug on the rh side. Check you bypass valve it is a little different to the 1640 but still easy to understand. I think you will be splitting it behind the gearsticks, there is 2 bolts hidden under the shift cover, and look for cracked pipes etc as well as the oil manifold.
@@BundyBearsShed Thanks for the reply, much appreciated!
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.
Yo dont have a remote valve stuck in working position by chance?
Thank you from northern wisconsin 👍 very informative
Glad it was helpful!
i put my bypass valve in without turning it i tightened the nut and now i cant get it back out. any ideas
non of my hydraulics worked but now my clutch,brakes and steering dont either
You will need to get it out as nothing will work with it sideways. Try grabbing the roll pin
i tried with needle nose vise grips and it wont budge the roll pin bent. i removed the hyraulic filter and you can see the bypass valve ive tried punches to beat it out,prybars nothing works.can i get to it from inside the rock shaft housing and beat it out? im about ready to weld something to it and use a come along to pull it out.
No you cant see it by removing the rockshaft housing.
finally got the bypass valve out by drilling it out..i replaced it and steering is working good but the brakes and loader still dont work. any ideas? scv valve maybe?
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
Yes it could be the problem, as pressure builds in the housing this valve should open and relieve it.
@@BundyBearsShedmaestro mi agradecimiento por contestarme aun que todavía no puedo leer tu contestación
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!
Sounds like a leak in the pto oil supply circuit.
Great Stuff! "Waving a hand" at ya from Grass Valley, California!
Cool, thanks!
Great details in this video.
Glad you liked it!
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.
Check you have not bumped the rate of drop knob just in front of your seat. Some times the draft cam can drop off the eccentric on the rockshaft too and it is best to lift the top and take the slop out so it wont happen again.
Does John deere 4440 have a bypass valve
Were is it located
I think it does in behind the filter but I havent worked on one in years so I couldnt be sure.
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!!!
check the check valve in the top oil tank is still in place.
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
Worth checking this and doing a filter change but they are known to have a split pipe in the Hi lo area at times.
How loose should the valve be in the bore, mine is pretty slack fit and will move a few millimeters side to side?
They are quite loose.
I seem to be into the same thing hope like hell it works
Hopefullly it does.
how do i get the air out of my hydraulic line on a 1020 john deere,hydraulics go down 1/3
Cycle it a few times it should self bleed.
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 .
Try closing the relief valve on the loader a little and let the tractor pump de stroke and see if that helps.
Thanks we tried that as well our dealer feels our tractor may just be worn out and it's leaking in a lot of small places. Just hate to let her go we have had it for 25 years she's been good to us. I'll keep watching though we have a 3130 also and a 6420. Your videos are great. And sorry to hear about your Dad. Thanks again from Nova Scotia Canada
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.
They do tend to want to lift but a fiber washer on the lever to stop it is the go, they had one on standard.
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
Front pump for sure but if you buy an aftermarket valve make sure you buy a closed center one and crank the relief valve to higher than the front pump pressure.
@@BundyBearsShed that would be for rear remote? Also what type of valve would I need? Thanks again
Any 1 or 2 spool hydraulic control valve will di the trick.
Por favor en español soy de Ortega Tolima Colombia 😊
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.
I use pointy nose pliers and just work it around.
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
I have not seen one in ages, I dont think we had the turbo model here that I can recall.
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
G Day Rick, You will need to split behind the gear sticks for that one. There is 2 sneaky bolts under the gear stick cover that you need to know about.
Thanks for the info. Have a Blessed Day @@BundyBearsShed
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 👍
It sounds like the pump may be cavitating and adding air to the system. Check the oil is correct for the system and also look for leaks on the inlet lines. Also check there is not a remote lever stuck in motoring or something and see if there is heat being generated around the FEL relief valve. I have not had a lot to do with the 5000 series but from memory they were open centre hydraulics with a gear pump.
@@BundyBearsShed Thanks Lance I will check everything you said and post back here. They are open centre and I thought load sensing as well (not sure). I am away atm so will have a look Tuesday next week. Thanks so much for your guidance.
@@BundyBearsShed😅
Do you know where this valve is located on 3040 Made in Germany Tractor ?
Exact same place on the JD 3040 as on my JD1640
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 not done a 30 series for some time but there should be some pressure there Im sure,
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.
Try pouring cold water on the injection pump and let the cool soak in for 30 seconds to a minute and try starting it. If it starts the injection pump is worn.
@@BundyBearsShed I tried that. It did work but no more. So problem is injection pump?
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.
I would lift the top off and check the main piston o ring, as the John Deere tractors will hold up for days normally I would go there first.
@@BundyBearsShed I took it off. The main O ring crumpled as i took it out. Thanks a lot.
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
I have found that blowing out the radiator at times doesnt do the job but a pressure clean seems to get the extra out and have them run cooler. Certainly worth a try. Make sure the trans is not over full at all as that will generate heat as well.
Amigo como va el sentido de la válvula yo tengo un 2030 hi me vaipasea el aceite gracias
The 2030 will drain the back oil if the valve is not fitted.
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?
No I would look at the hydraulic piston o rings.
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
Replace the loader control valve with a double acting one or check the machine has double acting cylinders
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?
Check this valve and check if you are in Hi on the Hi/lo on the dash, there is a known problem with the hi brake piston packing.
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?
If you are quick no need to remove the oil but if you are learning it is probably best to drop it.
@@BundyBearsShed ok thanks i are a big
Is the valve for the 4500 similar? Thanks much for your time sir...
G Day Sean, I dont think so but I have not had experience with the 4500
@@BundyBearsShed thanks sir God bless you...
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
Check the rate of drop screw in front of the seal hasnt been closed off accidently and the cam sticking up when you drop the top on must have the roller on the front of it and the back needs to run on the bolt on cam on the rockshaft. If it fell to the side the arms go straight up.
@@BundyBearsShed I didn't remove the top when I performed this work. Only the shaft and components.
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?
No it wouldnt crack the pipe they just work harden over time.
Does the transmission pump supply pressure to your wet lines
Yes
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 ?
Yes it is in the planning stages the small pump was the 23cc the big one was a 40cc
Did they have mixed open center and closed center utility tractors over there too?
G Day Brian, Yes open center for the low pressure and what is left over from the pto, hi/lo etc. gives charge pressure for the closed center system.
Bundy Bears Shed no I meant did they have models with open center front pumps. In the us some models were price fighters and didn’t have the good closed center pumps and valves.
In the 6010 series but the pump was up the back near the rock shaft, no other utlilty type tractors did that I know of. No open center front pumps anyway. The 5400 etc was a timing cover driven open center.
@@BundyBearsShed In the states we had 820,830, 1530, some 2040, some 2240, and some 2150 with open center systems. They are real odd ducks to work on. all the 5000 series are opencenter with the timing gear driven pumps and the 6000's are all what they call pressure flow compensated. It works like closed center but uses an open center style pump.
Always fun and interesting learning about what they do worldwide. :-)
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
I try and fit them as close to original as possible but I dont think it should worry the flow.
What is the valve that’s on top of the priority valve for the hydrostatic steering called?
I just think Steering pressure reduction valve.
my service book says to check spring compressed measurement. is that super critical? im playin with 300b hunting hydralic issue down myself.
Not normally.
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?
Is it coming straight up on to relief? if so check all valves are in neutral and feel for heat.
Aside from flush, filters and new oil, do you have any recommendations for troubleshooting a 1970 3120 with rear 3pt lift arms not lifting?
I suppose you need to work out if it is the only thing not working and if everything else is fine pop the lift cover off and you will probably fine what is wrong.
I have a JD 540 4x4 tractor and the forward reverse shuttle has quit working,can you help me out with some troubleshooting.
Do the filter, bypass valve and check system pressure.
Do you think that the 2140 4x2 can be put 4x4?
Probably but it would be an expensive exercise.
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?
Yes it can be the problem
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.
You may be loosing it in the loader control valve if it is set lower than the system pressure.
@@BundyBearsShed I measured the pressure by plugging in a gauge into the quick coupler on a pioneer nipple and throwing/holding the level. I adjusted the pressure to 2450 lbs and there was a marginal improvement in loader movement. But what happens is if the tractor runs at moderate idle for a short time the pressure builds to 2450 but the loader moves quickly for a few seconds then slows down. The pressure drops down below 2000 and is slow to recover. It takes 10 seconds to recover to 2450. Also if I run the engine at 2000 rpm the pressure does not build up and only if the rpm is 1000-1400 does the pressure build up ideally.
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
Check this valve as the oil you hear will be lube oil. you may have a split pipe inside. We will get to that on this one very soon.
I tried the Valve pulled it apart and it moves freely easy started the tractor and noticed My PTO turns all the time unless you really rev it have split the tractor and pulled the hi/lo clutch pack and the PTO brake and PTO clutch pack and transmission pump can't see eany damaged Steel lines going to inspect the PTO brake tomorrow
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?
No if it does that the ring has not been fitted correctly. The idea is to fit the ring up in the trans before fitting the cup.
@@BundyBearsShed Is blowout there a common problem? Bought tractor at a dealer and used it for a year and suddenly one day it just dumped a load of fluid in a few moments. Replaced screen and filter but apparently didn't get the gasket back right... blew leak just like original problem. Can it rest in housing groove for install? Need torqued?
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
You can adjust the lever where there is a bolt where it comes out of the lift cover. With the SG2 there is adjustment on the rod.
What would cause hydralics not want to work when its cold out
They wont work at all
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
That is a strange problem to have. I would say clean the screen in the bottom and make sure the new filter is in the correct way, early ones could be back to front but not the later ones.
@@BundyBearsShed Thanks for the reply. yes very strange. I have checked and actually there are different types of filters for the 3130. the supplier provided me with a model they believed compatible. but unfortunately he must have been wrong. now order an AR75603 which appears to be "free on both sides". hope to resolve. I keep you updated
If it has a big washer in the canister it has the AR75603 but early ones were closed at the outer end the open end went up to the gearbox. The later filter is way cheaper and if it had the early one you can fit the plate to use the cheaper filter.
@@BundyBearsShed I understand . thanks for these valuable info! the dealer had provided me with the AL25554. these days I get the AR75603 and I immediately test. It may be that the old owner fell into this mess, that's why he eventually took it off.
here we are . installed the code AR75603 and everything looks ok! the spare parts dealer apologizes for the mistake. The important thing was to understand and solve! no bleeding needed? the front pump seems a bit noisy. it becomes silent under load but slightly noisy with the tractor in neutral / running but stationary .
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?
as above
Much more complicated than a Massey Ferguson 188
G Day Huw, Yes completely different, this used open center to work the low pressure system then the left over oil for the charge pressure on the front piston pump. Both have things they are better at.
Hello im from Albania and i have problem whith hydraulic and problem with the steering system im waiting your help
John deere 1640
.
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...
Check this valve and the filter, you might need to lify the hydraulic cover off for a look I think.
@@BundyBearsShed Thank you very much, and sorry for the inconvenience
When attempting to remove the valve, does the filter need to be removed as well to allow the valve to be pulled out?
No it should just come out.
@@BundyBearsShed mine wont come out at all. Next im going to try some needle nose vice grips I guess to grab the roll pine. Not sure what else to do
hi ,i’m from italy, before remove the valve is necessary to renove all hydraulic oil?
Yes you do
hi. thanks a lot… today i ha e clean bypass valve but situation is not resilved.. i have a 3040 4wd .. if i power on and wait 10 minutes at minimum rpm and hylo anctive, machine lost the elevator… if i accelerate the motor, the elevator return operational.. any idea?
1980 John Deere 950 3 point hitch is stuck in the up position any advice? Thank you for your time
The draft cam will have dropped to the side of the rockshaft teardrop. pot the top off and shim the rubbing block and put it back on and it should be good. Make sure you have not bumped the rate of drop lever closed with your foot.
@@BundyBearsShed not sure i understand your terms for parts you are referring too.
@@BundyBearsShed was able to get it fixed thank you
Hi Corey do you mind explaining how you fixed it? I have the exact same issue with my 1640
@@acidlumin i took the seat off and theres a cover over some type of pin and i took a flat head screw driver and pushed on it at the same time as moving the lever that operates the hydraulics. I apologize that i dont know the names of the parts. Nothing more than a shade tree mechanic.
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
What model tractor? It is possible that the selector gate broke off the shaft as they do seem to do this from time to time.

Thanks.
what are the symptoms when that valve is not working properly?
Hydraulics are good one minute and everything stops the next.
Thanks ! 🤗😉
Thank you.

Hi, is the location of the filter bypass valve the same for a JD 2250 tractor? Thanks
Yes, it is
Thanks for the reply Lance, a follow up question if I may. I've had the valve out and is operational as per your video. I did notice that one of the locating lugs at the end was broken off. This is probably in the sump now I guess, I removed the hydraulic filter and it has very little oil in it, so maybe not getting oil into it. To test I turned over tractor and can see that no oil getting to the filter. So does that mean it could be either the valve is opening and dumping back to sump for some reason, the valve is closing and transmission pump is not working, or the hydraulic pump is buggered. Apologies for the long winded question, as a first timer, just wanted to see if I could get a hint before pulling it to bits, thanks Christian
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
Im not sure, I havent been around one now for years.
@@BundyBearsShed I found it! Can’t seem to get it to come out of the housing through.
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
It is hard to say from here, the front pump needs supply from the trans pump so pressure testing it would be a good start.
Anybody Have Deere 304J that needs the oil to heat up before it moves
I would suspect blocked suction screen or blocked filter and as the oil heats up it can run through the screen.
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
I asked if this valve would make my loader chatter when I raise the bucket this is on a 2040 2wd please feal free to text me on this issue 207 578 1645 thank you
No try plumbing the return from the loader control valve into the filter bowl, that way it helps to regenerate used oil faster.
No its not this valve this either stops it or doesnt, no in between.
That is how the return is in the filter. I put a new front hyd pump on and it was fine for 3 or 4 months plowing snow and back to chattering do you think it maybe the internal pump off the transmission is what the john deere deler said it was but they also said it was the front pump I just don't know u do something to fix it and then it's no different than it was u get discouraged what is your thoughts
Sr what this tractor? What serial?
John Deere 1640
Excuse me sir, I have a John Deere 8300 tractor, you will know where that bypass valve leads, I can't find it, I would appreciate your help, greetings from Reynosa, Tamaulipas, Mexico.

Am in Uganda my 6125m transmission and hydraulics gets very hot after moving for a while,drops the lifting pressure and warning lights on, but gears engage smoothly and it is powerful enough, help to identify the challenge, thanks.
Anybody who has had that problem with the Deere 304J not moving until oil heats up -please email me at john@wtractor.com
