NW Wyoming | Some have posted about replacing the original steering valve on the 10, 20, and early 30 series with a newer gerotor style. Does any one have pics of the install, and also a part number of the gerotor valve they installed. Thanks.

Mid-Missouri | I believe Jon Hagen has done this.
I just recently had the steering rebuilt on a JD 5020 and should have looked into what he did first. |

Ayr Queensland Australia 4807 | I hope to see what John has done the most important item is to ensure its closed centre. I have done 4960 and 4555 only for auto steer purpose just need to do the steering calculations number of turns lock to lock so it will be volume of steering cylinder divided number of turns lock to lock the ring size in the 4960 was 13 mm if i recall John may have info |

I did that conversion one time, on a 64 model 4020.. The gearrotor unit and steering column I used was I believe the salvage yard said was from a white 2-80 ? 2-90 ? It fit very well , like replacing a good mid size turkey with something the size of a pop can. We fabricated a simple welded steel adapter mount and made custom hoses to replace the original lines. With slight modification , the stock JD throttle tube, steering wheel and emblem fits right on the white steering column, so it looks stock. Love it , no slop, 50% faster steering , no oil drips and so much room to work around it . Has worked great for 20 + years. |

Ayr Queensland Australia 4807 | I wonder if someone could make up a kit to convert them over from power steering to orbital
I am doing a SCV coupler to ISO conversion using a simple push pull coupler and a lever to assist connection and disconnection ,i have to put it on this machine yet.
No more old couplers and levers to leak pull it all out and put it in the bin.

Renville County, MN | I have done several conversions on that style steering in 4020,3020 and early 30 series tractors. I used original valve housing that goes up thru dash where throttle and steering wheel mount. Made an adaptor plate and adaptor coupling to connector steering hand pump to steering shaft. Some hoses and custom made fittings. They work great. My first one has been in over 15 years with no problems. Cant even see, tell or feel it is different until you take cowls off. I will try and get some pictures up later today of what I had made. |

Renville County, MN | Here are some pics if I can get them to upload. This is a 30 series tilt wheel housing but all the parts interchange from 10,20 and 30 series except steering fittings and hoses. Actually 30 series is the easiest as it already has hoses going to original steering valve. |

Itta Bena Mississippi | What hand pump did you use? TIA.

Renville County, MN | I will have to look and see. I think I used a different hand pump on 30 series compared to 10 and 20 series. I tried to a get a major aftermarket ag parts company to build these kits and market them. They said there was no demand for them. I spent a lot of time making the adaptor plates and shafts. Tried to get a fitting company to make a couple of custom fittings but that ended up being really expensive so I just took two fittings and customized them and brazed them together. The return fitting is the tricky one. Has been awhile since I have put one in. If I get time today I will look and see what the part number of the Eaton orbit powers are I used. |

NW Wyoming | You don't happen to have any drawings of that plate do you? Thanks |

EC IN | I would think there would be big demand for an affordable simplified alternative. The original valves weigh a ton and are quite difficult to pull out of the dash and re-install. And in this day and age, it is sometimes difficult finding someone qualified and knowledgeable to work on the original valves. I have heard that a lot of deere techs won't touch them which is sad but I guess there is no port on them to hook a laptop to.
I wish I had seen this awile back because I am doing my 2nd soundgard addition and both times I had to buy an early reman 30 series valve in order to get the steering to work. Your method would have made it much simpler. The first one I did on my 6030 leaked at first and I took it out and back in 2 or 3 times. What a pain lugging that sucker up the steps and into a hot cab. Here's a shot of a 4840 cab with the early style valve I am using for my 4620.

Renville County, MN | I do not have any drawings of the plate. I do have some extra plates and shafts made up. If anyone is interested I guess I could sell the plates and shafts. Also the number of orbit power I used was a 212-1003-002. I could sure make up some more plates and shafts. |

Cheapest way is to buy one of the above and use the shaft cut and weld the correct spline works fine put the valve so the fitting face the operator and use 90 degree fittings .Make sure you have a closed centre hydraulic valve
