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. KZfaq 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!

Thank you buddy, good explanation very useful information, please explain the path of flow when the steering is not activated.

its supplies the flow, which senses the movement of the steering. its works when steering is moved.

Thank you, very useful.

Thank you my friend 4 sharing this video..

Thanks! Terrific video.

Buena excelente explicación te doy un 10.

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.

thank you for showing us ...

Thank you.

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.

thank you.

Thank you for helping me out with your video.👍👍👍

I like verymuch.thanks a lot

Tks for the comment. Yes, will simplify it.

I am the producer of Orbitrol and my brand is HANJIU. I would like to compare the price and performance with Orbitrol in the video.

I've always wondered how these work, thanks for the excellent demonstration and explanation!

Thanks for the comment. we are now available on Google play also.

Yes, we do, its part of our job.

good job, thank you!

Good Job.

Thank you, please rate the video.

Gud one..

Thank you sir 🇧🇩🤝

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

Merci 👍👍👍

Good job

For Anne Svendby with the MB Trac ; I have not seen the steering valve in an MB Trac , but if it looks just like this one , then you have to get it right out , scrupulously clean on the bench , & I,m sorry but the only way to get the seal arrangement out completely is to reference mark all the components at the bottom of the valve block , as this lot encompasses a manually turned pump that will provide " some " steering power if your engine ends up dead on the road , or if you are trying to pull - start it , this includes all the bolts , as at least one is a special bolt that retains a ball bearing in an oil port , mark it all , everything must go back where it came from ! strip off the bottom of the valve , then very carefully tap out the valve core & sleeve assembly with a wooden tool , take your time , the valve core will fall straight out of it,s sleeve if not handled with caution , & there is a con - rod arrangement inside it being driven by a cross - pin that operates the manually turned pump mentioned earlier , through a simple leaf spring arrangement , this is what gives the steering wheel it,s propensity to spring back to neutral , the tool to fit it all back together comprises a highly accurately machined steel sleeve that plugs into the central hole in the valve body , a plunger that looks a bit like a steel mushroom , with a plastic cap that dowels onto it,s top , this cap carries the lubricated & assembled kin ring & internal O ring assembly , & having fitted the outer , top single lip seal first , ( lip facing outwards , it just keeps the muck out , ) you locate the plunger into the bore , with the sleeve inserted first & dripping in oil , then stand the lot upright on the plunger,s substantial base , & snap it down centrally & firmly into place , withdraw the plunger , & tool sleeve , leaving the plastic cap in place in the top of the valve body , it is holding the kin ring & O ring in place , fit the valve sleeve & core assembly back in , then doing this will push the plastic cap out , reassemble the valve body pump etc , refit . ( 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 . This company,s tools are / were the very best . Be warned , different machine makers may use different sizes of components that look just the same until measured , then you find out the expensive tools you just bought don,t fit , I suggest you contact your local Agricultural College machinery dept for advice , as they sometimes " use " projects like this to train students on , & may already have the tools .For M B Trac knowledge I would look to Lincolnshire or East Anglia , a great old mate I haven,t seen for years went to work for a company called Townshends of Threekingham & Metheringham , Lincolnshire , they were Mercedes agents , his name ; Richard ( Dick ) Bradshaw , he was the red hot storeman who supplied me with many Leyland tractor bits from Stamford ( Power Farming , now gone ) in the 1990,s , great bloke ! Best Regards & Happy Spanners ! .

Great video but you left out an important point what stops the hydrolic fluid from coming out at the steering port

thank u come again

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

Dear youtube...LET US HAVE THE OPTION TO TURN OFF THE ANNOTATIONS AGAIN!!! Thank you for the tutorial vid.

Thanks you

Its a steering pump, used in back hoe loaders

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.

Super mamari sir

Bro can u tell in Hindi ,everyone can understand easily

Can we use this pump for hydraulic press

instructions would have been better with subtitles in English-language on all the different videos

Do you know what's the flow volume of this EATON CHAR-LYNN 236-4008-002 STEERING VALVE basing on the number?

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.

I found this pump (new pump) in scrap I goole it. Came to know it's a steering pump.

You did not say the keeping correct timing ( setting Pump rotor position ) when assemble.

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.

retentor sai por baixo?

what is the actual need of gear pump?

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..

good mornig

Y dont care abt enginehaks and padmakumars advice its very important

,whats the problim our orbitrol is hard to turn lift or right,, pls help ser

Where can I buy the o rings kit for the orbitrol MODEL number RW051B120R6A? Anybody here knows? I'm in texas in the RGV area.

Where is the orbital located on 3cx do you know?

Spool spool spool spool spoool spooooooollll spoooooolllllllll

I have assembled a orbitrol valve. Now the steering wheel is vibrating. Plz guide me.

Hello sir, can you explain how the no end lock and 14 degree lock can be overcome during the testing process

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??

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

How to strip the pump

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

jCB steering vibration that the valve same my steering... what the problem,,,???

Всё хорошо!!! На русском бы. :-)

كيف يتم الفحص

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.

Need to translate in Hindi language

не хрена не понял но судя по всему работать будет могли бы на русски перевести

ale pierdoli

This video is not useful he forget some other things (it is sad to see he making a video to make money ) that can not teach a ordinary man to fix .
