I just got a 2040 and the poor thing is leaking hydraulic fluid from under the steering wheel. It is REALLY loosing it not like a small amount but we are talking pouring down the column into the floor boards and everywhere. Does anyone know what needs to be replaced before I goto the JD dealership and order every o-ring and seal that it has?
2040 leaking at the steering wheel

There is a seal directly under the steering wheel you will need,(#6 in attachment) but most likely you will also need six identical orings(#33) that seal the steering valves to the housing. You will need a long oring pick to get these. The bottom one is about eight inches from the top and each one is about a half inch above the next. You should also get #4 to seal the adjuster when you reinstall it. The first thing to do is remove the steerring wheel. Next remove the large adjuster with the seal in it. Then put the wheel back on and turn it counterclockwise until the shaft stops moving up. Then grab the wheel and pull straight up to remove entire steering shaft assembly. Set the shaft aside and look down in the bore to see the six orings in there. Pick them out with an oring pick or a scriber or any other pointed tool you have. Coat the six new orings, (part # L34451) with grease and work them down the bore into the oring grooves. Be careful to get them into proper position. there are grooves between the oring grooves where the hydraulic oil flows. Next, look at the steering shaft assembly to be sure it looks OK. There are some shims(#20) that sometimes are damaged that can cut the orings when you slide the shaft back in. If any are damaged, you can usually get by with removing one or two thin ones since there is some wear in the valves. If any more than that are damaged, you might want to take the shaft to your dealer to have them repair it. There are some special tools involved to disassemble the steering valves. Once you are sure the shims are ok, slide the shaft back into the bore. with the new orings ther will be more resistance to pushing it back in. When it gets in far enough, you can turn the shaft clockwise to wind it back in. Then replace the seal(T22260) and oring(B3690R) on the adjuster and screw it back in and tighten the center portion to 50 ft lbs and tighten jam nut securely. reinstall the steering wheel and and you are ready to go. The picture looks pretty scary, but all the parts in the drawing from #11 through #32 all stay in one assembly and won't fall apart on you. Let me know if you have any more questions.

Yes, there is a filter. Actually there are two if you count the sump screen. The main filter is under the right hand step. It is a cartridge type filter. The filter cover goes straight up from the bottom with a bolt through the center that takes a 3/4" wrench. Just unscrew the bolt and the round cup/cover comes down with the filter element. Filter should be AR75603.There is also a rubber packing #R34733 to seal the cover.(see second pic) The sump screen is just behind the filter and it screws straight in the side of the transmissin case. It takes a 1/2" drive breaker bar to remove the plug,(#13) then just reach into the hole to pull out the sump screen.(#15) It is about 1 1/4" diameter and maybe 10 inches long. Be sure to drain all of the transmission oil before removing this plug since it will all drain out of this hole if you don't. The screen is washable. If it is not damaged or have any holes just wash it in solvent and blow it dry. If the system is clean, there should be little or no debris in this screen. If the screen is damaged the part number is R53169 for a nylon one and AR26375 for a steel one.

To start out.... It seems that people have tried to fix this leak twice before me. I don't think that they have known what they were doing.
It doesn't leak straight away when the engine is started... It starts leaking after the steering wheel is turned. I suspect bad O rings.
On mine #4 does not exist. I really don't see where it would go... On the shaft between the lock nut and steering wheel??? And can't imagine what it would accomplish there. Oh I see there are 2 #4s on the drawing. :confused2:
The leak seems to be coming around the seal #7. when I removed the steering wheel the seal #7 was not "held down" with anything and I could push it down into the recess with my fingers. It moves with the shaft and raises out of the recess as the shaft moves up, as the wheel is turned. -> I think that the seal #7 may be more to keep water out than oil in.
Thanks
Doug

Progress..
I am fairly certain that the people who "fixed" this previously didn't take the whole thing apart. The Adjustor assembly #9 didn't look like it had been moved.
I have been able to unscrew the shaft.
HOWEVER
When it is fully unscrewed it will shift a little bit up and down but will not pull out!
It will screw back in.
Any suggestions???

First the first #4 part # B3690R goes on the plastic steering wheel cover with the leaping Deer. The second # 4 goes on the bottom side of the adjusting nut.
Next the seal # 7 is supposed to fit tight in housing.

Oh, great, thanks! The cover is missing from a previous repair attempt.
It #7 wasn't tight in the housing.
Any suggestions to get the shaft out?
Any idea what it might be hanging up on? It is coming out until #16 is about even with the top of the housing.
Tap lightly with a hammer??? Use a bigger hammer?
