Adding Power Steering B7100 HST-D

I built the power steering on my 7100 by installing a danfoss steering valve, a surplus center ram and a power steering pump from a nissan maxima. The advantage to the auto pump instead of the tractor hydraulics is the auto pump has a built in pressure relief valve and a flow valve so the steering is the same from idle to full throttle. It takes time to make the column, power steering pump mount and the ram mounts. One finger steering even with a full bucket is amazing compared to the original armstrong unit.

Very nice install, looks like factory equipment! I bet if you built a few kits and sold them you wouldn't have any problems selling them. I know I would be interested in one for a 7100D.

The pump is run off of a 3L35 fractional horse power belt. The FHP belt was needed because the tension idler is putting pressure on the flat of the belt. The system uses it's own hydraulic system with a reservoir and cooler in front of the radiator. I am running Dextron III in the system.

I added power steering to my B7100, using a control valve from a John Deere 400 from Ebay and a 10" hydraulic cylinder . I have a race car pump that I was going to use but I could not make myself cut a hole in the side panel and hood for the belt, so I am running it off the tractor hydraulics. It works very well. The whole system cost about $350.00. I had to make the bracket where the cylinder attaches to the tractor, the rest of it is just bolts on.
