I hit a stump with my right front tire this evening and there was a loud snap. Now the steering wheel turns freely like the shaft may be broken. I see a "new" B8200 steering box on Ebay for $450, but I was wondering if I could do power steering for the same price. The articles that i see posted here show the standard steering box output connected to a valve, so that both the original steering arm AND a hydraulic cylinder are in place, like a power-assist instead of true power steering. I would like to know if anyone has tried using the power steering column from a JD 300 or 400 series tractor (the 4 or 5 port), and running from the hydraulic box steering ports to the steering valve, then to just a double acting cylinder for the steering. i realize this would only provide steering when there is hydraulic pressure, but should this work? It looks like something that could be done for less than the $450 for the replacement steering box........The B8200 is a 4x4 gear tractor with FEL and backhoe....
