    1970 4020 synchro PTO doesn't stop

    Hi folks. Just picked up a 1970 4020 synchro serial 223XXX. Previous owner put a new clutch in it a few months ago. Tractor runs and drives fine, all gears work. Has a few other issues though. Biggest one is that once engaged, PTO will keep spinning even when the (hydraulic) PTO lever is...

    1970 4020 synchro PTO doesn't stop

    With the tractor off, nothing is contacting any of the transmission or PTO fingers on the clutch. It is a little harder to tell when the tractor is running. The two PTO pistons are completely retracted with the PTO lever off. I couldn't find the PTO brake piston but I wasn't exactly sure...

    1970 4020 synchro PTO doesn't stop

    Thank you. This is complicated somewhat by the fact that this linkage seems to have changed 3-4 times over the course of 4020 production. Later console units (250XXX+) have a dedicated brake return spring. Mine only has a spring loaded pin, and my interpretation of the the technical manual...

    1970 4020 synchro PTO doesn't stop

    I got the shop manual today and went ahead with adjusting the linkage to the PTO valve. Unless I am missing parts or something came assembled wrong with my linkage, there is no way to maintain the lever into the "neutral" position or even a good way to know where neutral is supposed to be -- it...

    4020 destroker screw

    I just picked up an early '70 4020 diesel that is a bit of a hard starter in mild fall weather, a bit worried about how it will be with 2 feet of snow on the ground. Planning on adding a manual destroker screw but from reading threads there are a bunch of different part numbers depending on...

    4020 destroker screw

    Thank you gentlemen I will pull it off and measure. Confirming: It would be the smaller of the two bolts on the top of the pump, the one I marked with an arrow, which is directly opposite the pressure adjustment?

    4020 destroker screw

    Thank you!! I will note that I have no good way to see if there is a serial plate on the pump in that location without removing it, because visibility is miserable. JD's parts catolog says AR33249 is for starting serial numbers less than 201 (mine is 223). Are there other ways to...

    4020 destroker screw

    It does have a JD tank heater and it seems to draw current so hopefully it works!

    front axle pin questions

    I'm reworking the steering and front end on my '57 860 trying to tighten it up. Most of the parts that I am replacing look original, no loader ever on this tractor as far as I know. It does have cast front wheel weights. About the only wear part that is salvageable so far are the wheel...

    Ford 860 gen/fan/water pump V belt

    Can somebody please tell me the proper dimensions of the aux belt for a 1957 Ford 860, with original 6V generator? Mine needs replacement, but the v-belt on there now is 13/32" wide which seems overly narrow though it did probably work fine for decades. I see references to both 1/2" and 5/8"...

    Water in differential 860

    I'm sure the bulk of the water in the differential is from condensation, I am more interested in why gear oil/UTHF leaks from the drawbar bracket bolt which doesn't seem right.

    Water in differential 860

    I'm replying to this thread because it is relevant -- the swinging drawbar hangar was severely bent on this 860 tractor and only held onto the differential by one (the top right) of the four mounting bolts. I removed it to straighten the bracket and track down replacement fasteners and noticed...

    Water in differential 860

    Thank you much folks, very helpful. It certainly could have been gear oil in the differential, it was nearly pure water for a bit then what came out after the water was pale green and still a bit milky. From the state of the rest of the machine it probably hasn't been changed in a while. I...

    Water in differential 860

    When I first changed the fluids on my new-to-me, long abused 860 what came out of the diff housing was about 40% water, and I had to fish a bunch of gunk out the drain with a wire before it started to flow (initially I thought it was empty). The fluid in the transmission and hydraulic...

    1964 2000 4cyl gas hyd lift question

    There is a detailed video about repairing these on YouTube by Rachel Gingell, I won't link it because I'm not sure if I'm allowed but search for "Repair Ford Hydraulics: Lift and Draft Control" and she kind of goes over renovating the whole linkage. I found it very helpful.

    Ford 3000 NO SPARK with ignitor ignition

    If you have no spark out of the top of the coil with the ignition on, then you can ignore everything downstream and figure out why that is -- either you have inadequate voltage to the coil or the coil is bad.

    Ford 860 questions and choke plate

    New rotor, new distributor cap, and new dust cover (which came with a gasket, my old one didn't have one) and I got a nice hot spark that would jump almost a half inch on all four plug wires. And the tractor fires right up! I also rewired the whole thing, sized up to 2/0 awg battery/starter...
