Destoker valve

[DavidNeale]

I have A 1966 JD2020 with a manual destoker installed. I have heard that JD had produced an electric kit that fit the 20 series New Generation tractors. Does anyone on here have the part number for this? I installed the manual one years ago, when my fingers were young and functioned in the cold. I think at that time the dealer said it fit up through the 4020 model. The parts guys that knew this stuff are long retired, and the young parts guys are mystified by my question.
I might add that what problems I have encountered with this tractor have all been solved by advice that I have gotten from members on this forum, and parts from ASAP.
This 2020 HU rowcrop has been a great tractor. I have a 146 loader with a 90 inch grain bucket, loaded 36 tires, and handles heavy snow 6 months of the year. The rest of the year I use it with a 5 ft bucket and other various accessories.

Does your 2020 have the 1.38 in.3 hyd pump? Please post a photo of your 2020 frt hyd pump.

They don't show it in the partsbook like they do in a 3020 partsbook, but like Tx Jim said he needs a picture of your pump to see what pump it has to see if the destroker will work.

Here is a photo of the hydraulic pump on my 1966 2020 HU

The manual Destoker works great.
Unfortunately, it’s my old fingers that don’t work well anymore in the freezing cold of winter. A retired JD service manager suggested I try and find an electric one they used to stock for the New Generation tractors.

Don't know about that pump, it was the other style that the destroker was made for.

Remove the destroker screw and have someone tig weld a 5/16 nut on it and use a gear wrench

Another option is drill a small hole through flat sides of hex nut then remove roll pin install nut on destroking then reinstall rollpin through hole in nut & DS screw shaft. Then as Hay maker2 suggested utilize wrench to turn nut
