4010 hydralics

[Rwelder]

We were driving this tractor down the road and all the sudden the shredder dropped and steering quit . Checked fluid and it's full but now hydraulics . Someone said it could be the pump . Anything else that could be checked first? $$$$

Can you hear the pump turning when the engine is running? Check the drive coupler from crank pully to pump shaft. Sounds like maybe the pump stopped turning.

I'll second checking frt hyd pump drive coupler. The coupler has been known to get loose on pump shaft and not turn pump. If 3pt or scv powered impl. dropped when pump quit then that hyd function has leaking valves.

Agreed, and this is likely to be a two fold problem in that the leaking valves kept the pump in stroke constantly.

We've had this happen before and my guess is that its the stroke control valve. They stick sometimes and the dealer should have a tool that will take care of the problem. If it was the pump coupler it would have made a nocking noise long before it went out.

I worked for a JD dealer for 21 years several years back and I'm unaware of any "tool" to correct a sticking stroke control valve other than a destroking screw(parts key #6).AR33249 SCREW,HYD PUMP SHUT-OFF,ASSMY/FIELD ADD 15.48 USD

"Tool" can mean many things to a Farmer.

You need a de-stroke vavle like tx jim said. Get one. Install it on hyd pump, then with engine running, screw it all the way in then back out. Should fix it.

Your tractor may already have one installed. They are fairly common. Look on top of the hyd pump for a little T handled screw theaded into a nut @ the front of the pump.

Yea good job texas Jim for coming up with that stroke control valve idea......wait...what??

I didn't "come up with the destroking screw" idea. It was taught to me back in the 70's - late 80's while I was employed by a JD dealer as a service manager when I attended JD service schools at the JD branch warehouse in Dallas,Tx.:thumbsup:

Does sound like a rockshaft leak if the 3 point hitch dropped within seconds of the high pressure system loosing pressure

 

[gemzacons]

I had that same thing happen on my 3010 last spring. Lost all hydraulics, 3 point, steering and brakes. Turned out it was the pump on the transmission. That one is not too expensive but it is hard to get to. There is a procedure in the service manual to test if that is the problem. Hope this helps!

I've been looking all morning - pretty sad, I know,

For where to install the A-R27173 Filter Element; Stroke Control Valve.

In the paper I got from John Deere there was an arrow pointing to behind the left front screen, by the air filter.

You show a 4020, but your topic is 4010. I had a JD 4010 diesel. At about 9 years and 660 hours, the Ujoint off the engine disentegrated. Nothing moves, but engine runs. I worry about the same Ujoint on my 2025R, as it's totally inaccessible like the one on the 4010 is.

jrsavoie is referring to a JD 4010 rowcrop tractor built from '60-'63 not a 4010 CUT built from 03-'05. There's no u-joint on a 4010 RC

I will never understaND why John Deere recycles model numbers. I've had 3 John deere 400's and they looked nothing alike

Your screen goes in the hydraulic pump endcap. On the bottom of the pump you will see two large plugs. The one without the adjusting screw in the middle is the one with the screen. remove plug #21 and spring #18, some shims#19 and guide #15 should come out. Then packings 15 usually stay in the housing and will hold the screen in the housing. Use a pick to pull out the lower seal and screen should come out. The other parts above the screen should stay in place.

What other parts should I have on hand before doing this? I am guessing the seal at the least.
