B-414 building a power steering system?

tractorsam · Aug 15, 2009

I'm trying to resurrect an old B414 and the steering box is totally knackered. Parts are somewhat unavailable and rather expensive. A new box is available but is $600. I'm thinking that if I'm going to that much effort etc that I might be better off converting it to hydrostatic steering. I'm thinking I will plumb a rotary hand metering valve into the existing hydraulic system (via a priority valve) and build a new drag link incorporating a hydraulic cylinder with an appropriate rear mount. Does anyone know what the max pressure and flow rate of the system on the tractor is? Also any good ideas to find out how much force it will require to turn the front wheels so I can size my cylinder appropriately? Any other thoughts and ideas would be great. Thanks, Sam

Go find ya an old IH combine, like a 403 thru 715 series, they had hydrostatic steering with a cyl.

With a few hoses, a power steering pump, (I used one from a Ford) as long as you can build a something to hold the parts that the steering wheel sits on, you can graph everything from a IH combine, right over (custom built of course) to do what your asking.

I say combine parts, because sometimes, tractor componets will be more expencive, but the combine parts are the same thing and combine parts can cost less being if a place has alot of combines they part out, or tractors.

When I built my system, I called around, found the tractor parts, was about 40% higher priced, than the old combine that the same guy had parting out. So, I bought the whole combine for what it would have cost me to just buy the parts listed for a tractor.

Thanks. There aren't a whole lot of older combines around here and many of them are still being used. That said you never know what you can dig up when you start looking. Sam
