Hi,
I am in need of some help. I have a 70D that I have aquired that my Grandfather owned. Since I have gotten it I have it running and the pony works fine. I had a power steering fluid leak down on the roll-o-matic from the pedistal so I took it apart and replaced all of the o-rings. I have put it back together and I am trying to adjust the steering so it turns with the same pressure to the left and the right but I have found that it now turns shorter to the left than it does to the right and I am not quite sure where to start with this is it an adjustment or do you think I have something not right in the pedistal. Any help is appreciated.

Thanks

How much difference from one side to the other is there? Could you have installed the steering gear on the top of the shaft off one spline? I guess you can actually install the Roll-A-Matic portion to the pedestal out by 90* but you should see that pretty quickly.

You might want to jack it up and turn it so that you can see that you have the full range of travel. Whaterver you lost on the fet has to be available on the right ot you have somehow shortened the arc, and that could mean that you have assembled something out of place.

Did you have the actuator valve apart? Did you check for wear in the pins.cam faces?

I did not remove the rollomatic from the steering shaft that goes throught the pedistal housing to the gear on top. I removed the housing after taking the valves off of the pedistal and removing the steering gear. I dont think that if the steering gear was off a tooth would matter as it has teeth or splines all the way around. It will turn to the left so that the tires are at a 90 degree from the frame. they will turn to the right at approx 50 degrees. I am wondering if I might have put one of the square rubber things in the cylinder housing backwords. Any thoughts.

I agree with FIT. The top steering gear has a stop on it which only lets the gear rotate so far until it hits a stop inside the pedestal housing. If the spline is off, you have too many degrees of rotation on one side.

Actually, no, the stop is in the bottom of the rotary cylinder. In fact one of the pins is called a "stop" pin. However, I guess you could have flipped one of the vane backets in such a way as to reduce travel.
