Super 88 electric PS

Ohio88 · Dec 2, 2021

As requested here are pictures of the electric power steering on a Super 88
A bracket was made to keep the unit from trying to turn. Another Bracket for the control unit.
The motor is wired to the battery through a 50 amp fuse. I have not seen it use more the 20 amps.
The control unit is powered through a switch. No other electrical connections were made.

This is the upper shaft, welded the KIA shaft into the upper universal.

This photo is how the control unit is mounted, there is a home made bracket to hold it.

The bottom connection with the stub of Oliver shaft welded in to the coupler from the KIA.

How the tractor looks with the skin on.

How the unit sets in the tractor.

Okay the pictures did not load in the order shown in preview. hopefully you can decipher the pictures.

Thanks for the photos. That's a cool setup. I assume you're not concerned with dirt and dust since I see no insulation on the connectors, and that tractor is far too pretty to work. Looks great.

Since I mostly quit farming it does not see a lot of use. Next I want to try an add on hydraulic system.

Very neat setup, I'm interested in putting one on our 770 and an 880....
where did the nubbin clamp come from that is spot welded to the stub Oliver shaft,
right below the operator motor? Then this same nubbin clamp is tightened to the operator shaft
with the threaded bolt, correct?

And this is Kia as in the car parts?
Thanks so much for sharing pics and ideas. that is so awesome on here! GG

That is a REALLY nice, clean install!

Where did you find info on the basic electrical connections required to make the KIA unit operate?

Looks good!. When I worked for Dana yet they were working on electric power steering for cars but it was not KIA

The power steering came from a KIA Soul out of a junk yard. The numbin came with the steering column. It is welded to the a shaft that was on the Oliver and slides onto the bottom of the motor. The wiring I start on the internet, and went from there. It is fairly straight forward.

Now the reason for a KIA Soul was research said it was one of the heaviest on cars from the east.
Why a one for the east. If you use one from an American car you have to supply a speed sensor input, which can be done with another module from internet but it is another $90 to $120. I got the whole column and sold most of what I did not use. I think I have less then $100 in it.

On 770 or 880 you may have to check for room. You can use other models that are small. Toyota Prius is one you can use.

As near as I know it has to be pre 2012 as after that they changed the setup.

I found the wiring info on the internet. I will see if I can find the diagram in the shop and post it.

Thanks for posting this, I'm going to print it off so I have it and then start looking for a Kia Soul at the junkyard. Chris

Thank you, that would be AWESOME!

super great info, again many thanks for sharing.
Thanks to all those who share ideas and projects.
Have a great day today! GG

The electrical setup.
Including a list of vehicles that have power steering with default mode.

Ohio88 · Dec 3, 2021

I provided a list of vehicles I had to choose from.

rrlund · Dec 3, 2021

So is it all electric then or electric over hydraulic?

Ohio88 · Dec 3, 2021

All electric

Tramway Guy · Dec 4, 2021

Super 88D with a 6-port intake manifold? What engine? 283 or 310?

scootergmc · Dec 4, 2021

Here's a link to the forum thread you have printed for those interested. The list of vehicles and the wiring diagrams are in there:

Thanks for posting that info!

It is a 283 with direct injection. Just wanted to see if I could do it. Made a header so I did not have to cut a hole for the exhaust.

Based on the info that the writer provided about the fail-safe mode without an ECU, is the controller shown in Ohio88's pictures needed? Or is that a different controller
than the ECU.

The ECU is needed for making the unit work. It looks at the difference between what the steering wheel is asking for and the position of the output side of the steering shaft, then applies a suitable amount of torque via the electric motor to make the shafts align. If the ECU fails, the input and output shafts are still mechanically coupled to provide manual steering through the box.

Hope that helps
