Hydro steering on a yota

[CJsOffRoad]

I have a double ended ram from surplus center that accepts the same clevis ends that PSC sells for heims or you can screw 3/4" heims directly into the ram. I like the surplus center rams because they have mounting blocks welded to them. Don't have to worry about the clamps coming loose. The single ended tractor rams with the big clevis end will get slopply. If you plan on driving your rig on the road I would suggest calling PSC and getting a complete kit from them with a return to center orbital valve.

Read Billavista's article.



Dual action just means it has pressure on both sides of the piston(can be powered both directions). A single action cylinder means it only powers one way, and it has to be manually forced to go back to it's previous position. That would be like a dual-post lift cylinder... it only has pressure when raising the lift, then you are basically releasing pressure so it can drop down because of the weight of the vehicle/lift forcing the fluid out of the cylinder.

Surplus does have dual ENDED rams though(which I guess is what you were trying to get at?)... but I was saying to go with PSC or similar for street driving not because of that, but because the cheap rams have CLEVISES vs heim joints.

But there are ways around that too, check out what this guy did to a cheap ram to make it accept heim joints... scroll down to post #370:
