John Deere 3140 priority valve cleaning 

Very interesting, yes I would imagine it is easier on fuel and a Perkins is a great engine. I wonder what the power output of them is. The John Deere engine is definitely not easy on fuel.

It's roughly 100hp or 75 kw. It's the Perkins engine with the vertical diesel pump. However 3141 was not the only model to get the ADE Alot of smaller models have the 4cyl ADE/perkins. All the JD models with ADE engines numbers of that time period ended with 1. Because of sanctions against South Africa the Apartheid government had a drive to become less reliant on the international community for machinery. All tractors makes such as Fiat, Ford,Jd were compelled to the same legislation. Trucks manufacturers were also compelled to fit ADE engines.

@@johnwagenhauser9835 very interesting, enjoyed the information, thanks John.

Thanks very much Kieran

Thanks, might investigate that now some day. Thanks again

In the bottom of the tractors belly closest to the clutch housing. The tractor has to be split to access it directly, you will see it in my video.

Thank you for replying. Have a lovely day. Here in norhwest Sourh Africa its a wet and rainy day. 28mm last night

There is a gause pick up filter in the very bottom of the back end to screen any major dirt, worth dropping the oil and checking it. It’s behind a big nut and slides in from one side of the tractor to the other. Other than that nothing immediately handy, it’s juddering because of oil starvation to the main pump at the front which is caused by it not getting enough oil from the lift pump in the bottom end. You can start by testing the charge pump from the transmission cover on the the hi lo. There should be no less than 10 bar oil pressure there when oil is up to normal temp, (roughly 60-65 degrees celcius). I’m not very familiar with the 2140 but they are very similar to the bigger sister. You may have an internal leak and one of the most common is the hi lo which all takes a bit of diagnosis. Goodluck and if you do get it plugged into a gauge, just go through each circuit one at a time, pto, hi lo, 4wd etc👍🏻

@@connormcmahon3724 thanks for the fast reply Connor.

To the timing cover at the front of the engine. The pick up magnetic sensor is electric there is no mechanical cable if that helps

@@connormcmahon3724 is like a vajer to the tractor meter to plug in and then goes to something

Good evening dear friend, What role does the part you removed play and what is its location in the tractor?

This valve ensures you always have hydraulics for your steering and for brakes over all other hydraulic functions.

The hydraulic filter is under the cab in a metal bowl. There is a long bolt holding the bowl on.

Yes, problem is gone
