Power steering 212 grader

[quote="jumbo"]I have found a questionable aftermarket power steering unit for a 212 grader #9T441, I don't know if I want to buy it and take it apart to try to fix. I have recently discovered electric power assist steering which seems to be more workable and more beginner friendly on the install. At least watching the you-tubes I have seen. Fabricating parts for the original hydraulic after market steering is not too much concern, however, the electric seems to be a cleaner operation. It was even suggested that I mount a 4 speed transmission in line for the gear reduction something I had never thought of.

So, any opinions out there? Thanks for any help and opinion.:help:[/quote]

What type of unit are you looking at. I installed an "original" aftermarket Behlin power steering unit on my 212. It leaked but my local hydraulic shop was able to find the parts to rebuild it. You are way over my head on the 4 speed electric reduction power steering. Does the electric work on little enough juice that the 6 volt generator will support it or do you have to modify that also?

The Behlin is the unit that I can get; the unit has been sitting out in the weather for years if not decades and is seized tight; $150.00 as is. What was also suggested to me was an electric aftermarket power steering unit in effect similar to the Behlin only driven electrically not hydraulically. The 4 speed transmission was just a gear reduction to facilitate steering ease. The grader is already 12V, (earlier conversion.) Finding a pump to drive the Behlin unit if it can be repaired would be the next hurdle/cost.

The Behlin pump would have a sheave added to the live shaft with the pump driven off of that pulley via a belt. The pump looks like a old ford tractor power steering pump with a resevior attached to it. The pump runs at maximum 1200 PSI. Any more will blow the steering unit. I put a newer pump on mine and had to add a bypass line with the relief set at 1000 PSI. It works real nice.

That electrical steering sounds interesting. I would like to see more on it.

1) D4 Charlie; thanks for the craigslist link

2) OIH; I have yet to see any photo on the site showing how the unit is secured to the frame. All I really know is that you cut the steering shaft and insert the unit in the gap.Anyone have photos out there?

And to all the others out there, all the help I get is greatly appreciated. for 40 years I was a damn fine electrician, as a mechanic working on my first piece of yellow iron; ALL THUMBS! Skinned thumbs at that...

My 212 has a steering unit made by Rivenuis (not sure on the spelling) I will look through my brochures tomorrow, if I can find it I will put some pics on. There are a couple different designs. The type on my grader and the one you are talking about are torque multipliers and are like putting an 800 pound gorilla at the wheel so you can kill a steering box. It is best to be moving when you crank on the wheel. The second type is a hyd cylinder that pushes and pulls on the steering arm, a much better system. I hope I can find the info sheet, it will show the differences. Charlie

Mine simply has a flat plate standing up welded to the frame and bolted to the Behlin end bolts holding the unit in place. I am currently on the road headed to Colorado for elk hunting. I will take pictures of both the unit and the pump mount and post when we get back home just before Thanksgiving. I understand the skinned knuckles. I have the same, along with skinned shins, knees, and a sore back working on some of this stuff. It's all part of that dreaded Yellow Fever disease.

there are a few pics on my other thread on my 12 i going to be out at my grader today. so i will try and get a pic of the pump. i sure there very close from what i can remember off my 212. i would say you will have better luck with hyd then the electric.
