So years of my 200 lbs using the steering wheel to pull up into the seat have paid off with the steering wheel coming out of the steering pump. I am having difficulty getting it all apart, but am wondering how the steering shaft is actually held into the pump. It certainly feels like something broke, but I can stick the shaft back into the coupling(altho very loose and likely to come out) and keep steering. SO what actually holds the shaft to the pump?

The steering control unit (SCU) is a sealed, non-rebuild-able unit. The whole thing will have to be replaced.

Generally that is true, but some larger hydraulic shops may be able to do it.

Might be time to buy the technical manual - a bargain for the information you get for $55 (CD version).

https://techpubs.deere.com/Products/ProductSearch.aspx
The steering tube broke at the plate( part #8} on the exploded part diagram. I see that the part is NLA on Deere parts...but I haven't actaull talked to them. MY plan is to take apart the box and take the plate and tube to my welder and get it re=attached, then look at re-assembly. Judging by the look of the oil and crud all around the 'dash' area I would say it has been leaking for a while.Tempted to simply replace the unit with a parted out tractor box..any thoughts on that?

Also the Tech manual seems to consider it a rebuildable item...complex as hell, but they did devote 3=4 pages of rebuild procedure to it..

As long as the seal kit and small parts are available these steering control units can be repaired.

Agreed. The snap ring probably slipped out of the retaining groove. Simple & cheap fix as long as that's the only problem. :good2:

I had to reseal the steering control valve on my old 420 garden tractor after about 20 years of use. One day while mowing hydraulic fluid started leaking from under the steering wheel hub. Removed the entire steering column with valve. Carefully disassembled, cleaned and resealed the valve. Reinstalled it and was A-OK. If I recall the seal kit at the time was ~ $60.

Well a used part would be the easiest and fastest I'm sure.

Same thing happened on my 955,I welded it back together after taking it apart. If you can keep the steering valve together when you take it apart you'll not have any problems,I bumped mine and the springs came out, so I got a reseal kit. If you have a repair manual it's not hard to do. Mine broke a second time same place, I ordered a replacement cover on Amazon,10 dollars cheaper than local John Deere dealer, Just google part number

Try some of that Pink magic stuff. But you won't find it listed in any of Green leaders manuals. I think they still call it Bazooka Bubble Gum. Make sure you stick it on the end of the shaft with plenty of spit. and if it works don't tell any of the Purists, they will be all over you!
