Hello , I have serviced these several times , particularly on tractors with front - end loaders fitted , as the usual chain of events is that somebody turns the steering wheel while the machine is stationary , & the engine running at fast tickover , this causes an almighty build - up of hydraulic pressure in the "live " side of the circuitry , which finds the easiest way out , straight through the valve body top seal & kin - ring pack & then all over your cab floor ! Usually the replacement seal kit costs about £15 to £20 here in England , but you will have "one extremely hard time " fitting the new seal kit into the top of the valve body without the correct special tool kit for your series of valve , as it fits in quite tightly , & you can,t get at it to cobble it as it,s right up in the top of the valve bore . Also the parts of these valves are very finely machined & matched , it is imperative to keep them scrupulously clean & in exactly the original position , orientation & order , failure to achieve this will render the valve disfunctional on refitting . I,ve got the Churchill tool kit for my series of valves , can somebody tell me on here what SIMPLE video camera with a very good lens to look out for , as next time I do one I,ll try to video the proceedings & post it . I have an heavy eastern england accent , people think I,m Australian but I,m not , so stick with it for my voiceover ! I,ve been doing these seal kits since approx 1982 . Please note ; Churchill special tools still exist as part of The Sealed Power Corporation , near Northampton , England , buy your tool kits from them , to suit , as I did . Don,t copy mine , you will infringe patents , & these things are exceptionally finely machined , so they would not work if you did . Work out what you,ve got & phone SPX . Happy Spanners !
Much appreciated, but your video(s) aren't the only ones. RUclips recently changed things such as video player screen size and "hide annotations" button, they needed to leave it alone! I hope some system mod. is reading ;) As to your videos, great work, highly informative...thank you again!
you have left out important points,the inner spool can be assembled in 2 positions,with a shift of 180 degrees ,in respect to outer spool.If assembled in wrong position ,the steering jams ,when u turn left.And the gerotor in some models,has a correct position in respect to the needle pin.

Mate, thank you so much for saying that. It is exactly what has happened to me. Jams going left after I reassembled. Thank you thank you thank you! I was pulling my hair out.
My wheel keep going left I have to turn right then left and then right for them to go back right. But I have never open or removed the orbritol. Is this my problem if so how do I rebuild it???
El Mero Mero things that cause it, 1)the plate springs holding the outer spool position, to the inner spool are faulty. 2)The steering cylinder seals or tube is damaged. 3) The slots on the inner spool is clogged. 4) The steering column bearings are damaged. 5) The rubber coupling between the steering column rod and orbitrol is damaged. regs
If you are taking one apart make sure to mark the parts according to the original alignment. Or else you will have to make a total mess and take it apart many times to figure out the alignment. The unit i took apart did not work properly unless it was in its original alignment.

( YOU OF COURSE USE A NEW SEAL KIT FOR ALL THIS ! ) The golden rule is to mark everything first , before dis-assembly , the tool part number here in England for this is V.L. Churchill MS 62/1 , MS62/2 & MS 63 , I only live a few miles frm the old churchill factory , but they seem to have disappeared , if you can find them again I,d like to know where they are , someone mentioned Blisworth or Brixworth , Northamptonshire , but as yet , no joy .

If I might add... also, gear pumps are the most common type for most transportation applications. They can deliver high flow, maintain high pressure and accept harsher operational conditions than larger piston, screw or vein pumps for similar or less money. Also, they are cheaper/ simpler to fix compared to most

hello, do you have any written info about the orbitrol valve, with functions, applications and more? im having a hard time reading a lot of ambiguous internet post about it, also i would like to know if you know something about the applications on boats for the orbitrol. Thanks for the video
wrongly done, you missed the cross pin and its importance....also there is no drain in steering unit information given by you is completely wrong..atleast read the catalouge for once..
Hello this is tanveer I googled a lot about how orbitrol works but I am enabled to find any thing . Can you please tell me about any link or any e- book where I can find how obitrol works . I will be really thank full to you.
brother this is only how to assemble orbitrol, i mean to ask that is there any animation by wich i can understand how orbitrol control oil flow in steering unit
Do you know of anyone who re-seals an orbitrol made by sumitomo Eaton? Preferably in the U.S. Mine leaks around the splined steering shaft female end. Appears to be a lipped seal there. Not sure if that's the seal or just a wiper?
God bless if some one install like this. Because this assembly has a timing and if it is mis matched steering will not work right and if it is off from a articulated machine, one could be killed if he stand articulating area.
For the pump/assistance to work the inner spool must push against the centering spring to allow the respective ports to open and allow fluid to flow to left or right cylinder you do not explain what holds the outer spool against the effort applied to the inner spool to align the spool ports for this to occur - otherwise the two spools will just keep rotating together and fluid will be dumped back to the tank without any assistance.
hi i have an danfoss 200ls on one of my jcb ive got some problem with it.when i turn right its smooth but when i turn left its hard to turn.and also i would like to know the diameter of the ball valve.could someone help me please??
I can't figure out why that bull just sits there in there like that it will fall out the other side of the line if you move it around is it supposed to be like that
it a check valve on P to T.when pump working the ball block P to T port and when pump not work and you need turn streering wheel the ball move and open T port to orbitrol for oil sucktion
hello u have showed the assamble only u have not showen the allinement of the the internal gear,shaft and the outer gear its the most importent to assamble the orbital unit,since some orbital do have there own allinment we can assamble how ever we want but some dont have that we have to do the allinment ,since i am doing this job since 20 years.
Hello Sir, do you have any document or a video in which the alignment of the inner and outer gear is explained. Also the basic simulation of the oil flow from the oil flow passage between the spools could be understood more clearly. It would be a great help. If you have any document please mail me at "vrushabh.sawant@gmail.com". Thankyou
You are 100% correct. I jacked with one for almost two days to figure out what was wrong. I just wanted to replace the seal which was leaking and did not pay enough attention to the alignment of the wheels. After the seal replacement steering wheel started to turn by itself as soon as i touch it. By the time that i figured out whats wrong i have taken apart the unit for 7 times 🤦♂️ it was a total disaster.
People might wounder what am talking about (Let me give examples the ball ,the two washer and the bearing assemble he forget that or possible he don't know

@ El Mero Mero : Just change the pipes from left to right and from right to left .
its supplies the flow, which senses the movement of the steering.
its works when steering is moved.
I've always wondered how these work, thanks for the excellent demonstration and explanation!
If you are taking one apart make sure to mark the parts according to the original alignment. Or else you will have to make a total mess and take it apart many times to figure out the alignment. The unit i took apart did not work properly unless it was in its original alignment.
Thanks! Terrific video.
Yes, we do, its part of our job.
Thank you buddy, good explanation very useful information, please explain the path of flow when the steering is not activated.
Thank you, very useful.
Thank you, please rate the video.
