JD 2140

rusty6 · Oct 5, 2017

The previous owners delivered the JD 2140 today and I've had some time to do a few things with it including getting the lights working. The light switch had separated and lost contact. I nearly lost all the internal parts when I was taking it out but got lucky and found all the springs and contacts. Fitted it all back together and added a little JB weld to hold the switch from falling apart ever again.
Got the engine oil and filter off. Picked up new hydraulic oil and filter from JD. Yes, I went with Hyguard.

While you have the hydraulic oil drained check/clean the sump screen. These tractors are good until you have hydraulic issues. Mainly running them after the brakes have polluted the system with material.

Yes, I'll do that. It has just about 8000 hours and I think the hyd oil has been in there for quite a while. Steering and brakes work amazing. I have never driven such an easy steering tractor.

Video from today fixing the light switch. I was advised by the previous owner to always run the hydraulic oil over full by several quarts as
he had that information right from John Deere. Anybody else heard of this and why it would be necessary?

I always add a few quarts to my loader tractor.....probably not necessary, but if the loader is up, it has drawn some oil from the reservoir. Just a feel good thing, I guess. Ben

If loader has double acting cylinders hyd oil level in tractor reservoir should remain very close to the same level no matter if boom is full up or full down. JD utility tractors similar to 2140 should have hyd oil checked with engine idling. On older models with screw in dipstick to check oil level nut should just be resting on threads.

IIRC you are to check the hyd. oil level right after being shut off. This will result in it being higher after it sits awhile or overnight and oil drains back to the reservoir. So maybe that's what he was talking about ? because if you check the oil first thing in the morning it will be higher than the full mark. Being overfull a little won't hurt especially if you have hills.
It appears the loader is hooked up to the rear remotes ? If so I'd get a joystick valve and plumb it in more direct and free up the remotes. This will also increase the performance of the loader. The manual of the loader should show how to hook it up to various models.
Hopefully you got the manuals with this purchase. If not John Deere will sell you some. They are a must have.

Nice looking tractor you will like it.

I nearly 100% positive that JD 20-40 series utility operators manual states to check hyd oil while engine is idling

Saw your video, and yes, change the loader return to the filter canister and the
supply to the pressure line on the remote valve plumbing. Also, if you don't know
the history of the tractor, drain and flush the coolant and add a conditioner to help
prevent cylinder cavitation. Good tractor, you will be happy with it. Ben

Yes, just checked the manual and they recommend checking the hyd oil with the engine idling slow, range lever in park, draft links lowered. But no mention of adding oil above the full mark.

The original owner added a diverter valve to one of the remotes so in effect it has triple remotes. Loader is hooked to the 2 originals and the diverter valve has an extra set in it to plug in a remote cylinder for the mower or whatever implement. Not sure if I will keep it that way as it covers the top link bracket for the three point hitch. (Top link is missing btw).

??? The loader has it's own joystick control or there are two SCV levers on the right side of the seat dedicated to the loader ? Were the SCV valves optioned with the return line to the oil filter housing? Or does the oil travel three inches and dump into the transmission case ?

Yes, on the 2 levers by the seat. One for the boom and one to tilt the bucket. Same as I had on the Massey. On that one, if I wanted to hook up to an implement's hydraulics I just disconnected the bucket cylinder hoses at the remote couplers so I could plug in the implement's hoses. Could do the same on this JD but that extra valve the original owner installed to divert the flow to either the loader or an implement seems to work. Just a lever on it to switch back and forth to loader or towed implement.

Tractor looks and runs nice.....should give you yrs. of good service. Not sure, but it looks
like the side shield screens are plugged?

They sure are! Helped warm the engine up for the oil change. I had been cutting some bulrushes and that fuzz just fills the air as I drive over it.

Does the loader have it's own hydraulic valves? Most of those loaders tapped directly into the tractor's pressure lines and returned to either the sump or the hydraulic filter cover (feeds to main pump). Running the loader through a rear hydraulic valves is much more restricted.

No, this 146 loader is set up much like all the others I am familiar with. Running right off the remote valves. Or in this case, through the added on diverter valve. I'll try to post a picture of the valve to show what I'm talking about. They had it set for max. flow on the remotes and the loader was too fast for my liking. I set the flow back down to about mid way and we will see how that works.

I've never seen a valve similar to the valve in photo nor seen one attached similar to that valve. I think it would have been better to attach a 2 spool valve just for loader the way JD engineers did it from factory similar to 2nd photo.

So I think you are saying just add a third remote outlet? I was thinking the same if it is possible on these tractors.
I removed that accessory diverter valve yesterday after draining the hydraulic oil. Now I need to get a couple of JD to Pioneer adaptors if I want to connect to anything else on the farm.

They were great tractors. My uncle bought one used for the blower when he built the 80 foot harvestore. You may find it a bit light in the
rear. Just the nature of the beast.

Only way I've seen 3rd & 4th remotes added to JD utility tractors such as your 2140 is similar to photo I posted earlier showing how to attach a 2 spool valve for frt end loader. Returning oil to hyd filter causes better operation response from FEL[/url]
