De-powering a Koyo Steering Rack
HTML-код
- Опубликовано: 12 сен 2024
- There is no non-powered steering rack available for this car, but it's being converted to electric powered assists and no longer needs the hydraulics. There are instances where you may wish to do this just to convert a power steering equipped car to a manual rack, such as drag racing. Whatever your reasoning might be, there are steps you should take to protect it internally.
Previously I've made a video of rebuilding a Koyo rack for use with hydraulic power steering and that video is available here. An extremely similar rack to this one. Most Koyo rack and pinion gears work exactly the same with very similar parts so these two videos should apply to the vast majority (if not all) of the import cars that use them... which is most of them. Koyo is prolific. You can find that video here: • Rebuild Koyo Power Ste...
To see how Gabe installed his Prius power assist, watch this one...

Dude's got a great how-to, car collection, and channel!
The steering rack relies on power steering fluid for lubrication. Take that away and it creates a slow self-destruction for its internal parts. The short explanation is to grease and seal it so that it can't escape. That's exactly what I do in this video, but you know I'm meticulous enough to also rebuild it in the process with new parts that will stand the test of time. And while we're at it, might as well make it look the part, too!
This video is largely a test of new camera equipment while completing a different and necessary step of my GSX's restoration. This has totally been in my way of completing its assembly. The column modifications will follow later, but the rack had to be finished before I could assemble the rest of the front suspension.
I made a 30-day follow up video for the Patreons.

BMD make nice gear. Lens?
21:24 Verklempt! indeed, it's been a long time coming.
@@ChrisSuperTube Canon EF 24-70 f2.8 USM, Canon 70-200 f2.8 USM, and Sigma 14-24mm f2.8. There's a 28-200 f4 Lumix jam coming for run & gun, but who knows when I'll ever see it? I demo'd the whole outfit on Patreon. Editing software and all!
@@Jafromobile i have no idea what any of that means.. must be expensive.. i reiterate. thank you patrons! lol
@@blu73 Chris asked about the lens, and I used 3 during production. Those were just the lens specs. ;) And thank you!
That's a absolute beautiful 1G he's got there. I'm still sad I had to get rid of mine in 2007. Still mis that car. But that got me to this channel, and still watching 17 years later :)
He's doing some genius stuff with it, too! I started collecting parts for this mod first, but he beat me to it. I love what he did with his AC system, and at some point I need to feature it.
What I did is make a "manifold" that both lines go to then it has a line that runs up the firewall into a filter to let it breathe and vent. It also allows me to fill it with a little bit of oil to keep things lubricated. Works very well on the 2 cars I did it to.
Excitied to see the electric rack stuff when that happens. I deleted the power steering in my ol' Bimmer after the first test drive and the rack puked its guts out. Not that I really need it when the car is moving but I'm not getting any younger and I'm definitely getting soft when I have to throw my shoulders out in parking lots. Needless to say I'll be happy to learn something from your trials and tribulations. Thanks for the upload.
Man, they've gotta make a seal kit for that thing... There are several different electric steering systems popping up on all kinds of cars, Kia's, Hondas, surely something out there can retrofit? If they make a seal kit and you wanted to rebuild the rack to bring the hydraulics back but forego the mechanical pump you deleted, Volvo's got an electric hydraulic pump on the s90 that you can mount remotely somewhere else. Check out Tunes + Tunes, they've got it in two different cars now with a how-to!
Two videos in one day, you spoil us Jafro!
When you come to RUclips to see Jafro, I want it to be like when you stayed overnight at grandma's, and she let you stay up late and eat all the things that mom and dad won't.
The new camera is great. It doesn't succumb to welders flash which is a huge plus
From my editing chair, all the things it doesn't do make me so happy now! I'm so tired of cameras that try to do everything all the time. Because you can always tell. Accelerate that video and that thing is now screaming. The more I see that becomes automated, the more I crave the mechanical and analog options. This camera is the perfect blend of both.
Ideally you'd also modify the pinion shaft (weld it up) so that you no longer have the slop from the torque rod, since you don't need it to operate the spool valve any more.
I don't know how this valve is supposed to work, because mine is pinned in place? It doesn't move?
@@Jafromobile The torque rod inside the pinion flexes, albeit a tiny amount; in order to direct the flow of hydraulic fluid in the correct direction so that the power assistance is working with the driver rather than against
Hit that notification faster than my cat can catch a fly. Thanks Jafro for a great video, I'm having a much better Saturday night now
I meant to switch this live 4 hours ago. Just got home with more video. ;)
This is unreal timing, I just learned about the Prius PS a few weeks ago for my build. I’m pumped to see it in action on the GSX!
Good thing I have procrastinated my my koyo rack de-powering long enough for you to make a video about it!
Excited for the Prius mod. I swapped in a manual 1g rack into my VR4 and am looking forward to this modification!
Thanks for posting videos Jafro. And thanks for the camera Patreons!!
One of my favorite RUclipsrs. Thanks for posting relatable content!
Can’t wait for next video!
Love the video Uncle Jafrey. Keep 'em comin', and looking forward to the next.
I like the idea of going electric. When dealing with older cars, getting hydraulic steering parts that work properly and last can be so difficult. I don't know how many times I had a rebuilt P/S pump whine or leak oil after a year. I would encounter many rebuilt racks that leaked. Hoses can be difficult to locate, so it often means taking your old hose to a hydraulic fabrication shop.
I almost did this with 40 feet of hydraulic lines for the green Galant's AWS system. It would have cost $1,700 to have them just make the lines at a local shop. I nearly bought a really nice hydraulic crimping machine, but the urge passed. You and I think a whole lot alike. If hydraulic is better than electric... then where are all the hoseless/cordless hydraulic tools? How come those never caught on? Hmmm....
Twice now I've fixed whining Honda power steering pumps by replacing o-rings at the intake hose. They draw in a stream of tiny air bubbles along with the fluid intake hose that sounds for all the world like some kind of horrible mechanical issue. You'd never guess it was just a bad seal. I wonder if other brands' power steering pumps have the same issue?
Just as a note, Molybdenum paste is the best you can use in this case, it really sticks to the surfaces and is a much better friction modifier, than any regular EP grease, it is expensive but, it is worth it, Loc-tite and Rocol sell this product.
Heads up on the prius eps, if you can figure out a way to get the steering angle sensor to read correctly you'll love yourself as without it you won't have any return to center without aggressive amounts of caster angle.
I do plan on using a bias controller and everything I can possibly integrate with Haltech.
Thank you for the video, Jafromobile.
Wow new camera looks awesome, love the welding footage!
Good shit Jafro.
Good gravy…
I appreciate you jafro
I started blasting!😂😂😂
...and you know, I don't see too good.
Best. RUclipsr. Ever. 🤘🤘
I am gonna be using a Prius steering setup for my rx7 so I am VERY interested in this modification
Omg I want to do the Prius steering in my 04 Sebring coupe
New Jafro... 🎉
Not a dsm guy, Just awesome videos!
12:00 Don't tell me I can't over do something. You watch me.
😂 I imagine you with the valve assembly and rack completely suspended in grease. There, is that too much?
@@Jafromobile Your imagination is limited my friend.
And thankyou!
There is a manaul quick rack kit that was produced just incase you don't get out much lol ALSO EPAS was used in a lot of these kits
You know, I just did tie rods on my Toyota. The whole thing's blown apart right now for a bay shave and I've wanted to find a good way to tuck my power steering. I may need to find a new set of tie rod washers...
They're included with the rack seal kit. At least my kit included them. Whichever's cheaper, a new set of inners or the rebuild kit?
😍
Does Abe have any pics or videos of his install? I'll be doing the same to my 1G soon.
He's working with me on the 2g, and I'm sure I will be covering his installation as well before it's over. He managed to tuck the motor high up in the dash out of everything's way and I want to see that one myself.
This is the 1st mod for my Colt, it will be arm muscle stering power 😅, the 4G63 is a long ways if I get to that point!
My Colt is actually already manual. The GL from 92-95 was a factory manual rack.
@@Jafromobile mine is 97, for what I have seen, for what I want the Colt, it is better a Hydraulic stering rack converted to Manual, once it is rolling it turns sharper with less angle stering, but is much harder to turn and standing still or very low speeds.
Why does your video look fuzzy in the close up shots? Love the video as always.
Hahahah. Nice try!
But if you're serious, About 60% of the time I'm shooting mostly around 24mm which is extremely wide-angle. For stuff like part number labels, I use digital zoom for the extreme close-ups and that will not maintain pixel density. All the pixels get swole.
If it's action close-ups it's because I've moved from my original point of focus and it's practically a manual focus camera. I have to manually adjust it (my fault). Still does better than the old AF camera did, though.
All vehicles should be electric steering assist.
A belt driven fluid pump and associated lines, cooler-
are all so antiquated. Parasitic latent horsepower.
You and I think alike! It was great back in the 1950's. Nobody's using hoseless hydraulic drills and impact wrenches in their garages.
eh. I think I'll just fit an electric pump and custom hydraulic lines when I need to delete the saginaw. I'm still here watching tho.
Go check out Tunes + Tunes. They did that to a couple of 2g's!
1:48 I can turn the wheels that fast with no power steering, but it takes a lot of muscle ngl
Abe used finger. It was very effective!
Black Magic you say. WITCHCRAFT I SAY!
6K footage is certainly a powerful brand of wizardry at the very least!
