De-powering a Koyo Steering Rack

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...

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. If you want to know more about the camera, or if you'd like to see the extra content and join all those legends in my credits, visit: / jafromobile and sign up! What are you waiting for? Everything contributed goes directly into my production. I couldn't have managed to get a camera anything like this one-without them, and I'm amazed by how much better things look around here already! Everything contributed just helps me make better videos. They make this investment in me-for YOU. Because making all of you happy makes me happy. This channel runs on gratitude!
Thank you for watching!

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!

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.

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.

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.
@Jafromobile
@Jafromobile 20 дней назад
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?

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?

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.

@Jafromobile
@Jafromobile 20 дней назад
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.
