hydraulic steering for d8

Yes there was a power steering attachment on a few of them that I saw but don,t remember too much about them. Once in a great while a tractor would come into the dealer with it on but it,s been too long ago to even remember much about them.

I have not come across hydraulic assist but have fitted full hydraulic steering way back to D8s must be 50years ago,the hydraulic steering was made by some aftermarket company (Rivinius?) and came in kit form,a pump,control valve,the servo cylinders and plumbing,the OME steering levers and linkage were removed,the clutches could not be disengaged till the engine was running.

Here's a few pics of an old D8 with the Hyd. assist that was sitting on the side of the road. It would have been nice to pull the top steering clutch inspection covers to get a better look, but....

Here is the rest of the page that AJ posted.....part of patent drawings I got from?????.......appears to use a double acting hydraulic cylinder down there to do the work.

We had one on an old slide rail RD8 we had on the ranch years ago with a similar setup.

There were single acting cylinders the operated the clutches inside the bevel gear housing with spring return. There was a small two spool, two position hydraulic valve that that mounted on the dash as in the pictures.

Ours was powered by a priority flow divider on the hydraulic pump running off the front of the crank for the lift circuit, as there was a LeT CCU on the rear of the machine.

It's been at least 20 years since I had seen the tractor, sorry I don't have any pictures.

thanks for the pictures and such. I just finished rebuilding the steering clutch's on my d8. I rebuilt the power steering cylinders with seals from a local hyd. shop. i took it out of the shop tonight for a test drive, everything worked great, except it was-20f out and i couldn't wait to get it back in the shop.

The last pics. of the D8, is that a HI-OUTPUT tractor? It has twin stacks. catskinner
