I am always impressed with your videos. You know what you're talking about, you cover the subject completely, and you throw in a little comedy. Well done again.
Ha ha ha ha, I finally understand how this mechanism works. I always wondered how the power assist knew when to stop, ie how to prevent pressure assist from steering beyond where the driver wants to go. It's all about that little torsion bar. As soon as the steering wheel is released, the torsion bar springs the holes back to a neutral position so no more pressure goes to the side you're turning towards. Genius.
Yes torsion bar backs to neutral position but how it is turned when moving? is there a clutch like system ? if released how the gripping is over? i understand the mechanism but i wonder the details.
@@juvenildr it puts pressure on the side of the steering that you want to turn it, it wont turn the rack by itself, it just puts pressure there to help you turn the steering easier.
jesus. for years, even through school as a mechanic noone was ever able to explain to me how the decison of witch path the oil should take was made. the freaking torsion valve. god dammit. that one little pieace. 10 years this has been bugging me
Everyone, watch the behind the scenes of this video (the link is in the description). You will be amazed by the amount of time he spends researching, filming and editing, just to end up with a couple of minutes of video. I'm impressed! Well done, sir!
One of the best explanations of rotary control valve operations. Many youtubers skip that part bcz they don't understand themseves the operation and importance of this part as the heart of power steering system.
Wonderful forensic analysis of how the power steering works...I have some knowledge about the rack, but with your video all my unknown content disappear from my head...Now thanks to your video i have plenty of knowledge how it works. Thanks a lot for your video. Sorry about you wife getting messy because of your Power Steering Rack autopsy. She deserves a new dress and a dinner out invitation. ;-)
And this here is my brother's tooth brush. I could not find his old one, so I took his current one, I'm returning it after I'm done. WOW, it is my o-pinion that this is a great rack on that steering!
If you blow piston with low pressure air there will be allot of blow-by the rack piston hard seal ring . Fluid pressure expands the seals I suppose to a tighter clearance.
Hi Speedkar99! My steering became squeeky at full lock after replacing the utility belt, and on colder mornings, it is squeeky and jerky through it’s full range of motion. Any tips or suggestions what to look for? Thank you!
Thanks for teaching me how power steering works, AND making me laugh! It’s nice have my own source of grease rags validated, lolol Sorry you burned your hand. But, applaud you leaving that bit in the video. Makes us amateurs feel less stupid when we do that. And, the “other wrench” was perfect!! Have had to use it myself. As I told my neighbor: “It’s not a question of whether or not we CAN take it apart. It’s only a question of what shape it’s going to be in afterward.” ;-)
Ok wow, this was so helpful! Definitely gonna be checking out other videos, taking a course in mechanics and you have helped me so much! I really appreciate it!
Lovely video, I just want to ask, can the pinion gear make the steering to be hard of stiff, I use Mitsubishi Montero 2004 limited and the steering is stiff, we have changed the power steering pump still stiff, the mechanic said it is the steering rack pinion that is faulty, can the steering rack or pinion make the steering to stiff. And there are no leak on the rack at all.
Your camera catches some fluid on it's lens. Did you use some protection sheet to your camera lens? Acrylic sheet works good to protect camera from oil and grinding debris.
@@speedkar99 downside of acrylic sheet is scratched easier, you need new sheet every once in a while. A flat glass provides excellent clarity to image and ease to clean, but with prone to shattered when hit with something hard.
what is the name of "oil seal" that prevent oil from the steering pump to go away in unintended direction in the rotary valve? is it called a oil seal? and is it effective to replace it or replace the whole rotary?
Hello from India. Very informative video, especially the torsion bar thing. I have a strange issue with my humble ford fiesta with hydraulic PS. I find steering assistance is a bit more than I would have liked. Car turns tack sharp but I'll love to put some more effort in turning. I got a new rack, suspension kounts, struts to fix some of the other issues but this one is giving me a tough time. Any suggestions?
hi there, You made a very detailed video and many thanks for explaining that. I have a question regarding the failure you mentioned at 6:12. That failure could be due to a torsion bar or hydraulic pump or steering rack seal leakage, I am facing this hard steering problem in my car these days and I am wondering if you can help me answer this in order to fix my car. Many thanks Regards
Just a quick question. When you steer to the complete left or right (when u reach end) the high pressure fluid would be still directed towards that direction. What is the mechanism that will prevent the pressure build up and return the fluid to the return line?
We had to change the steering rack on our car and the new one had a different splien to steering columb so we swapped out the one from the old one to the new one so we had to take out the valve assy press out the splineretaining pin and swap them over and reassemble the valve assy to the housing .. now we are wondering does this have to be set in to the housing in a certain way/ orientation as weve got it fitted but now not sure if there should have been an alighnment procedure we centralised the rack then just slotted it back in...and did up the retaining nut any advise appreciated
Presumably they have to be aligned with the hydraulic lines going into the rotary valve and the rack is aligned with the steering wheel pointed straight
@@speedkar99 hi thanks for the reply my son was over eager to get it all fitted back in during the rain and unlike me who has experiances just put it all back in saying see there simple stop fathing around well bottom line is its sort of half working one way so he's got to redo the whole job again so was just wondering as it can go in 2 ways 180 out so I bet he's put it in wrong Well the best way to learn is doing it wrong maybe hell listen to me next time thanks
@@speedkar99 Hi thanks for reply weve dropped the subframe on our old golf mk2 once again had the rack off once more today the outer valve assy locates with a locating pin the inner assy with the tortion bar can be fitted in 180 so 2 ways so we took it out and put it back 180 and the large port holes on inner and out lined up before they did not putting it back one subframe bolt cross threaded and the captive nut in the chassis has come loose URGH anyway fitted the hydraulicks back and did a test now worse than before like its working against us so we had it right the first time but it wasnt working right but did do some assist so we are buggered now going for another new rack from a differnt supplier £180 down the drain live and learn
Hi it seems we had it fitted correct the first time as it sort of worked badly you can press the pin out of the tortion bar and remove the inner assy thats how we changed over the splines shaft but cant understand why it wasnt working properly we set the rack central and fitted the valve assy it rotates as its fitted so cant alighn any holes to outer case housing but seeing they are in channels i dont think it has any bearing on alighnment as the switching is done via the internal valve sleeve with tortion bar attatched we tried both ways the original sort of worked when the interna lvalve holes did not alighn with the outer when we re fitted it this time we turned it 180 in the locating lugs and the large holes on inner and outer sleeves both alighned the small ones did not so we though ah weve fixed it reassembled and now worse than before its fighting us so weve given up on it for tonight ordered another rack But we would like to know why our original was just leaking badly from rod ends but still worked ok this new one never has .... it seems a simple device but we are stumped we will look at it next time its off and try test it with an air line to see if the ports work properly but with only 2 options and weve tried both im stuck for now
Update got another new rack and this time once again the splines on the steer column valve assy shaft are diff again this time its 18mm dia and 22 splines it seems there are 3 diff sets of splines for this rack type and the dia can be diff so this time we managed to get a rare second hand flexi to column shaft with 22 splines so we will change that over this time and not touch the rack in any way EVER the trouble is they dont say on the car parts sites what spline type they have they all fit similar car but not the short flexi shaft to steering .... job stalled now till post kicks back in after christmas HO HO HO once its off again ill look at the bad one again its bugging me why its not working properly i should be able to test it with an air line and see if ports work ok but thats a job for after the holidays now
Good video, I was surprised from this shown system I was thinking it is simple. I have a question I have Saab 9-5 2008 model now when I turned its driving wheel to the left or to the right I hear a "tik tik" sound and disappear if I drive straight, I checked the components of my car wheels and change some of its parts, but the sound didn't disappear. I some how sure it's come from it's power steering system. Can someone give me what a problems in the steering system causing that, I will appreciate any reply to my problem, thanks.
More informative in the first 2 min. than the 8 videos I watched before this combined. Answered everything I wanted to know. Thanks Mr. Speedkar- you, your wife, and your brother's stolen underwear are legends
GREAT video, BUT we don't care to hear about this person's pants or that person's underwear. Also turn down angle grinder volume. Aside from that : GREAT VIDEO !!! Thanks for the deep dive into all those details. I never had a clue how hydraulic power Steering worked until I watched your video. Now I know.

Could you do some videos of the different fluids in vehicle systems?
Which part determines the power steering weight of the steering rack? Is it the pump?

Love the dry humor!
The torsion thing! THATS what I was missing in my understanding of how these things worked! Thank you!
As always, a great explainer video!
Agreed, that's the key to the steering rack, there's not much else to it
Me too man, had to watch dozens of videos to find out; this man did a great job!

Aaww..that so sweets...
So helpful 👩🍳
she must have seen you just wipe up the steering fluid with her clothing. Oh he must need some oj!
Oops I sprayed my wife

Thanks glad you appreciate my work
How is it that only You show the inner working of the rotary valve and torsion spring? Thank you for teaching us. Very comprehensive as usual
I agree, I was looking for more information on this and couldn't find it. The only way to learn is to tear things apart.
7:52 * Nut rounds * "...I'm gonna have to use another wrench to get it off". * Proceeds with angle grinder *
Seriously....I wasn't expecting that nut to round out but my angle grinder sure did. 😎
Angle wrench!
Thank you for your.most comprehensive presentation. I stumbled onto your presentation by accident. Consequently I can say thank God for accidents.
Glad it helped!
this is the best explanation i have gotten on hydraulic power steering. Even better than my teacher's. thank you! :)
Currently studying for an IP exam, this was very helpful. Thank you.
As an engineer, your video is the only I've found that explains the mechanicals. All the others talk about theory. Cheers
Even though I knew how this works, I was waiting for u to make a video on it 😊
Glad you enjoyed it
Another very nicely detailed explanation of inner workings.

I like you man. and respect to the wife.
this is one of the moste instructive useful channels.
Well done speedkar99! Your video really reveals and explains how the hydraulics assist the steering effort.
Welcome
Awesome in depth explanation of the system. Thanks a ton!
You are welcome
absolutely perfect explanation - They should call you Car Professor :)
Nah I'm speedkar99
3:11 your wife brought you some lunch XD
Yep, that helped me power through this one hehe
@@speedkar99 I assume she didn't notice you using her pants
I had to LOL when your wife let out a little yell when the power steering fluid shot out of that rack.
Haha yep she got a squirt
It just the scream when he touched the hot part at 6:40
this is so perfect. the speed. the explanation
You are the best explaining things... thanks
Glad you enjoyed it

Love those precision 5-inch wrenches. Guaranteed to remove any bolt👌
Right on!
I love your videos. So thorough and funny! Repeat viewings for me as you go fast and I’m slow
Excellent taredown explanation.
Thanks
Very informational. Appreciate the cutting to reveal each component. Did talk just a little fast though. :)
Wheel effort makes pressure increases actuating idle air valve open to increase engine rpm to compensate 85 Supra.
If you blow piston with low pressure air there will be allot of blow-by the rack piston hard seal ring . Fluid pressure expands the seals I suppose to a tighter clearance.

Thanks! I didn’t realize it was a valve with constant pressure. I’m guessing variable assist systems are more complex. Do you have a video on that?
Thanks a ton! Awesome breakdown, one of the best. Appreciate the time and discs you went through for this!
Glad you enjoyed learning about steering!
Good job u are the best 👍👍👍👍👍👍👍
Thanks I sure am

Did you use some protection sheet to your camera lens? Acrylic sheet works good to protect camera from oil and grinding debris.
Yeah I learned my lesson the hard way...the first steering rack I grinded open scuffed up the lense pretty bad so I don't protect it with anything.
@@speedkar99 downside of acrylic sheet is scratched easier, you need new sheet every once in a while. A flat glass provides excellent clarity to image and ease to clean, but with prone to shattered when hit with something hard.
Really legend in explanation
So, the higher the pressure of the liquid, the easier will make a turn the steering wheel ?
Yes. And that's why the pumps have a flow control valve.
That comment about his brothers underpants gets me every time. lol
Great educational demonstration ,,,and the out come is the power steering rack is now scrap metal 😆
Yep, I'm making the most use of this scrap car.
Nice explanation. Try to explain to me what happens in the catalytic converter
Can you do a video on how the clock spring on the steering wheel works.
I already have one
I learned a lot,Great video;thank you!
So the steering rack is lubricated by grease, and is not simply bathed in the power steering fluid?
lawd your humour kills me, dude
Love it

That would be an awesome video
Just a quick question. When you steer to the complete left or right (when u reach end) the high pressure fluid would be still directed towards that direction. What is the mechanism that will prevent the pressure build up and return the fluid to the return line?
Thanks man, this will help me pass my finals. And, I love the wife.
I love the wife too
When installing pinion gear, do I have to adjust the fluid holes or not? or it can be installed directly without considering the fluid path
That was very clear, thanks mate !
thanks man, very nice and interesting video, ❤
5:28 anyone know how to take this apart without destroying?
On the diagram you showed what did the blue line do?
7:56 ahh yes cutting things up with an angle grinder really puts off a spark show!!!
Love my grinder. Cut a whole car apart and it's still a champ.
Had to check my top drawer. Those shorts look a lot like mine.
