Closed center hydraulic troubleshooting

Working on a New Holland h9880 bale wagon, that has slow hydraulics.

[@shawnedwards5946]

Look forward to your videos when ever they come out! I’m a mobile equipment mechanic as well and learn something from your videos each and everyone of them. Your honesty, integrity and lack of the drama BS is very refreshing these days. Keep up the great work and God bless you and your family.

[@1waukesha]

Awesome video man! Much appreciated that you take the time to share your experiences! Cheers from AB Canada!

[@Jabbaholl]

I'm happy you decided to carry on making videos. I'm always learning something interesting and you're one of my favourite content creators.

[@landlifem5872]

Yeah always picking up information on equipment

[@disturbedcarrot]

I've subscribed to loads of channels but Warren is the most genuine one out there. It's like a class rather than an entertainment piece. Hardworking folks like Warren are the true backbone of an economy, country. And I love how he doesn't ask us to click on the subscribe button!

[@stewartflannagan3734]

I agree with everything you say but it wouldn't bother me in the least if he asked people to subscribe.

[@disturbedcarrot]

@@stewartflannagan3734 True, maybe I could have made my point better actually. It's the channels where it appears their primary purpose is to grow subs through whatever enticing means that really annoy me

[@sdeery]

Glad you decided to keep posting videos.

[@nicke1903]

Yeah me too

[@mitchwilliams5504]

I am too. I really look forward to Warren’s posts. I always learn a lot...and story time is a plus.

[@dnixon8767]

Thanks for posting Warren. I enjoy watching your wealth of maintenance experience on different makes and models of equipment.

[@petergraham2262]

Thank you for not leaving you tube Warren. That was very interesting and educational. I have several heavy hydrostatic machines and I have always been baffled by the compensator control in a closed loop hydraulic system. Watching it twice explained it better than I have ever heard before. Everything you put up on KZbin is more than just education. People like you and Watch Wes Work are masters of your trade and damn good teachers. Please keep it up and all the best from Scotland. Take care

[@Drew6709]

Warren, thanks for staying on KZbin and making vids. And thank you for the way you explain the operation & repair of equipment. You make the explanations easy to understand. A+

[@robertstibz9506]

Awesome job again Warren, keeps me going through difficult times watching you videos.

[@westerntruckandtractorrepa1353]

I pray things get better for you.

[@gregkoontz7983]

Wow! I am old school with air over hyd. spool valves and to be schooled on updated equipment is a blessing. Thanks for the $ savings.

[@gregphillips9670]

This is good stuff. I'm a truck mechanic and don't get to work on hydraulic systems like this so it's cool to watch you and learn.

[@Ham68229]

I absolutely hate those electronic control valves. Just too much can go wrong with them. They can and do rust and that can cause a lot of issues as well. Around here, we call 'em hay stackers. Awesome machines so long as they're working properly. This is why you're probably the best mechanic that works on farming equipment. You figure it out and yes, you even go to the manual occasionally, I've known a few mechanics that don't do that and "think" they know it all. Great video as always. Cheers :)

[@davidj4662]

Makes me realize just how much I don't know. Great learning resource, thanks. You are truly talented.

[@JH-qi7fz]

Best channel on KZbin!!

[@lulzcow33]

i agree 1000%

[@disturbedcarrot]

Absolutely, and it's a shame he was thinking of quitting. Hope he stays with us for a long time.

[@thorsbyguy5121]

Learned something about closed center hydraulics today. Thanks Warren! This is by far the best HD mechanic channel on KZbin. ;-)

[@rsmith6572]

Warren, great video. Love to see your thought process when attacking a broken machine. As far as trying to figure out where the piece went, well just know probably many hands had been on that machine until YOU got there. The original problem may have been the pump? being weak but there is no way to know for certain. The bottom line is YOU fixed the issue not someone else. YOU. as always great job. Be safe out there

[@jamesbuttleman3130]

Your knowledge about so many different pieces of machinery is amazing, thanks for sharing the videos and your expertise.

[@kimazbell460]

Great explanation of how the closed center hydraulics work in this application. You are one of the best at diagnosing mechanical problems and I always learn something from you. I hope you keep posting as I look forward to watching you work through these issues. God bless you and your family Warren. Dogs Included!

[@alanfisch6912]

Thanks for all the detail in describing that pressure compensated system. I’m a mechanical engineer (retired) a few of my years were building hydraulic units that were used in steel mill continuous casting. Now I’m dealing with a few hydraulic issues on my John Deere 6210 Tractor.

[@harrykeel8557]

I viewed this video the other day, and it was the first time I had ever seen one these types of farm equipment. And was a bit confused on how it worked, even when you explained it. This afternoon I was skipping around KZbin and saw one the bale stackers, on another farm and watched. Interesting you know we live together n the greatest country ever. A country that has allowed people to come up with machines that help eliminate the back breaking work of dealing with square hay bales.

[@douglasmayherjr.5733]

Great Find. One of those calls that makes your week or month, should have impressed your customer. Your knowledge about all the mechanical systems is impressive. Thanks for showing us how you work through it. You would be a great instructor at a Technical School, if you had the patience. Thanks again for the videos.

[@glenvanbavel8710]

Very interesting video, I always learn a lot from your videos. I’m sure glad you are still making videos. You are by far the best mechanic I’ve seen. And the best one on you tube . Thanks again Warren.

[@morkorson4196]

Thanks for making more videos and staying on you tube Warren, never seen machines like these before, very interesting designs.

[@PoliticalGangster]

I surprise myself today by understanding some of your explanations. It's going to be good weekend.

[@nickb7609]

Fascinating and great description of the troubleshooting. One thing i dont understand though is the lower orofice plate being missing - I could see it if it had been mis-assembled at some time, but I thought there was a seat for it, so unless it disintegrated surely it should be in the cavity and not blasted into one of the hoses or block (lord alone knows the problems this might cause!) - I can also see it being improperly seated allowing a high flow as Daniel Boyd said. Either way great troubleshooting skills and really pleased to see you posting again.

[@lukemorgan6261]

Nice little video Warren!, hydraulic problems can be a pain in the ass even with a schematic drawing. Good diagnostic work there my friend 👍 regards, Luke 🇬🇧🔧

[@bosomofvictory]

Thanks for continuing to make videos Warren. I have learned quite a bit from watching you.

[@tommygreist9560]

Great discovery diagnosis Mr Warren which always makes a great video. You saved that outfit alot of money. They have the right man for their maintenance.

[@gwbuilder5779]

Hats off to you Warren, hydraulics can get complicated pretty quickly. I remember working on auto-cycle trash trucks and those electric trigger switches were a constant pain because if they dumped a wet load that liquid would cause a negative trigger and stop the cycle mid push. I didn't see a lot of electronics on those cylinders, I'm sure they the switches for automatic mode.

[@haystax]

Awesome video and explanation. Balewagons will make you pull your hair out and never discount poor engineering from the factory as the root of all problems on these damn things. The new ones sure are a lot better than the old 1075s I started with

[@mongomay1]

Thanks Warren, Needed more experience troubleshooting agricultural hydraulics, compared to industrial systems.

[@timothyreed6054]

Outstanding troubleshooting Warren.

[@steamboat1341]

This video couldn't have come at a better time. I'm working on my 1069 bale wagon and trying to figure out why my right push off always bleeds off just enough that the right push off ram extends about 9 to 12 inches and then I get a loud whining sound. I've tracked the lines through schematic drawing labelling each line until this -30 weather hit with wind chill - 54 below; I bet you miss Wyoming Warren, weather hit but I'm learning. Thankyou so much for these videos Warren take care.

[@86lowrider]

Maybe the guy that wanted to sell them a new valve block took that Orifice with him? Glad your still posting. 👍👍👍

[@stevedoe1286]

You might be right or they just could not figure it out. So sell them a new one

[@svthorasailing4868]

Yep,it worked and then it didn’t with parts missing.

[@Mdarkone1977]

Really interesting video Warren. Was nice to see you explaining the equipment your working on and what it’s for.

[@AbdulKhan-cy3vq]

Awesome job. Thanks for sharing. God bless you and give you more strength and power. They should pay you more. Fixing the machine and making video at the same time. Not easy

[@mikefightmaster]

Like your description and logic of operation. Just like more "Story Time".

Good job. Hydraulics are usually such a challenge when then are so many operations at once.

[@markreetz1001]

Man Warren, you put out a video where you are explaining in detail how cam gears & cover work or fail then the next vid you are in full detail about haystackers. It's amazing all you know!

[@danielwatson1815]

We use to set variable displacement pumps by backing out the Pressure cut out, screwing in the stand-by all the way (stokes the pump) & then bringing the pressure cut out up to the desired set pressure & then backing the stand-by down until you get your 25 - 35 bar stand-by pressure. This is on Drill Rigs. These days we use 3 ball valves & 3 hoses, we stroke the pump off itself from the output to the compensator & with the 3rd hose we run that back to tank so you can dump that LS signal if things start going pear shaped. The way you're doing it is a pretty safe way to do it.

[@Gustav4]

Wish I understood what you were saying fully but its a lot of terms. Good job fixing it, we have been in the same situation with mechanics costing us 100x more than it should've

[@ranger5721]

glad to see you on and showing us the ones that enjoy your work that you do

[@mongomay1]

Hi Warren, Throw a roll of barrel size garbage bags in your fixit truck, they make good seat covers, floor mats and cut it open to make okay tarps and nut/bolt catchers underneath the equipment or something to lay upon and can be used to cover an open motor to keep dirt out.

[@Chuckiewashere]

I appreciate your videos! I have learned a lot from you! Please don't let the the negative people steer you away from posting videos! Stay Safe!

[@DON-T909]

We Never had any doubt you would fix it Warren

[@byronmill]

Stall pressure on a closed center hydraulic system is essentially the same as the pressure relief valve setting value on an open center hydraulic system. They are both the maximum allowable pressure in the system under any given condition.

[@rustynail4676]

A true mechanic hear not just another parts changer 👍

[@rl3898]

That is a very good point, a lot of that changer type around these days !!

[@wotnoturbo]

Closed center hydraulics come into their own if you want to perform multiple functions at once, challenging to get your head around if your not familiar with them, good walk through of how they work, glad you decided to continue making content, greetings from EUSSR Ireland gulag ps I got unsubbed & notifactions knocked off by the powers that be - corrected 👍

[@archstanton9206]

Very interesting. It does make a guy wonder where the heck that orifice went, and if it will make itself known someplace else in the system later.

[@garyeverly574]

Keep up all your good work your doing a great job keep it up and tell the people that run there big mouths to walk a day in your shoes and I bet thay can't I e been a field repair person sents 1980 and your doing just fine good luck on all your opportunists

[@JHruby]

Nice fix, Warren. Man, if you wouldn't have had experience with knowing that fan motor should slow down... Great diagnostic work and showing everyone the value of reading and understanding the service manual. So question is where did the missing oriface go? Can it just fall out?

Excellent job troubleshooting nicely done!👍thanks for sharing bud have a great weekend! Oh I saw in your other video you broke out those new lifting slings for that radiator removal was wondering if you ever got them . Take care now.

[@steveholton4130]

Are you saying that the original orifice either found room to dislodge or simply broke into small enough pieces to move out of the body and into the system randomly? If so, is there not the possibility that it will become free to move into a WRONG place in the system?

[@maxxtech8532]

Kick Ass Warren. Great Job.

[@Nudnik1]

Rexroth Bosch has classes on you tube how load sense variable displacement piston pump s work. Excavator s use these . Kawasaki or Rexroth. Pumps cost $30k + Charge pressure runs of gear pump about 300-700psi . Charge pumps usually get tired first. Load sense valves get clogged or oring fail. I have a John Deere 690e excavator no one can fix has same issues. Gonna try you test for swash plate and spring on start up... Excellent work thank you for helping others.

[@noelhohberger1188]

Great stuff Warren

[@paulcrocker2837]

I have never work on hydraulics, and find this very interesting, I love fault finding.

[@danielboyd5455]

theres an orifice in the bottom side of the block that will get loose and get sidways and cause the hydros to spudder and run slow

[@danielboyd5455]

noted: guess i should watch the whole video before opening my mouth! that was the orfice i was talking about

[@davidholder3207]

Remember Miss Shilling's orifice made to counter engine cut-out in early Spitfire and Hurricane fighter aeroplanes during the Battle of Britain in WW2?

[@PoliticalGangster]

No but sounds interesting. Please explain.

[@vanellusx2785]

@@PoliticalGangster the Merlin engine being carburetted and not fuel injected could suffer from fuel starvation in certain negative ‘g’ manoeuvres. After the starvation and returning to normal ‘g’ the carb would flood which could kill the engine. Miss Shilling was a lady engineer who worked for the air ministry and she invented a modification to the carbs on the Merlins which would stop the flooding. It was a washer with a hole in it and it was nicknamed “ Miss Shillings’ orifice” in typical British humour😉The carbs were later altered to a different design but in the meantime Miss Shillings’ invention helped the RAF win the air war. She must have been quite a character being female and an engineer in the 1940’s! Think she and her husband raced cars in their spare time. That’s my understanding anyway and I stand to be corrected by those of greater knowledge😬

[@davidholder3207]

@@PoliticalGangster The Rolls-Royce Merlin engine originally came with a direct carburettor, prone to cut-out due to fuel flooding in negative G. Engineer, Beatrice 'Tilly' Shilling, designed a thimble-shaped brass flow restrictor (later refined to a flat washer) with precisely calculated dimensions to allow just enough fuel flow for maximum engine power. It came in two versions, one for 12 psi manifold pressure and another for the 15 psi achieved by supercharged units. This fixed the issue to the surprise of German fighter pilots. The rest is history!!
