Picked up a standard 4010d Syncro No 3 pt, with a solidly locked up trans. Linkages have been disconeted, seem to be able move the range shifter at the transmission, gear shifter moves very little.
What is your guy's thought's? Hope to get the top cover off tomarrow and see inside. We had to use a cat 950 loader to pick up the back end and roll it up on the trailer. The case 580 hoe wouldn't get one tire off the ground. While it was hoisted we could spin one wheel and get the other to roll the other way. So should be transmission problems.

Previous owner said that we couldn't start the motor because the trans is locked up???? Shouldn't the motor be free of the trans if the pto clutch and drive clutch are both positioned right. We didn't try to start it as we had enough troubles.

I will assure anyone that if the motor spins the input gears, and you have the top cover off, you and everything else will be splash lubed. Does it get every bearing all the time, maybe not but one could run allong time well coated on the outside will fluid.(light workload) I had the motor Ideling about 500 and was sliping the clutch to just roll the gears over nice and easy. Think 3-5 times the rpm and with the cover on or off!!!!

previous owner said that he working the stack yard when it happened shifting between gears. they knew of the tow mode setting, I am thinking a that she might be miss aligned in the top shaft. My hope is to be able to pop it into netreul and roll it off my trailer. They said it shifted hard before. Probly gone part this one out, any one need some standard parts? Have a home for motor.

Got cover off, used the screw driver trick to pop the offending front syncro. Fired up motor,(purr's nice) pto works fine, clutch works looks fine, but engine makes the missing teeth on the reverse gear on the differental drive shaft and the messed up ones on the top shaft shake rattle and rock the tractor. Eventualy while try to diagnose the hydrolices not working we must have got it just right and we locked it up again. 1.5hrs later we poped the same sycro and walla instant 1/4 rotation of the one tire we had jacked up and movement in all the gears.

Next question, on our 4010, or 4020PS we have full hydrolic power by the time the tractor starts usaly or shortly thereafter. If the charge pump is out on this one or the clutch is pressed, shouldn't I still get hydrolic pressure. I ran the motor for maybe 3-5 minutes and the steering sort had pressure several times came and went, and the brakes pumped up a couple times. We played with the hydrolic shut off for cold starts, hoping that if the stroke control vale was stuck it would pop loose.
Right now we figure we are going to steal this motor for another 4020 because this trans has more than $1000 worth of problems(I think?), But I want to test as much of the parts on it as I can to see if thay are any good. Maybe Monday when we unload it off the trailer I get you some photos of what happens when someone as a chain and a bigger tractor, instead of a screwdrive and some knowledge.

When hyd oil leaks back to sump it takes a little while when engine is started for hyd oil to make completely through hyd system.

FYI a 4020 powershift hyd system is a different as trans pumps oil while foot pedal is depressed which as you known isn't true on a syncro-range..

It's possible the tractor was towed without putting gear shift lever in "tow" position. Doing so will gauld a gear to the top trans shaft . Yes engine should start with a correctly operating clutch depressed. You could look into clutch inspection hole in the bottom of clutch housing for broken operating bolts or fingers.

Hi I looked at a 4020 last year for a guy that was the same symptoms you have. I looked at it but never got the job. Guy just wanted me out there to say what the problem was. Then adjusted me with a large screwdriver and fixed it himself on the cheap. It looked to me as if one of the selector disc in the syncro on the top shaft had worn and dropped down in the gap. There was 3 i think, of 4 discs that where loose and one so tight you could not move it. it appeared it was stuck between gears as the syncro would not come back to neutral. The tractor stalled dead on him in the field when he changed gear from what i remember him saying
. I talked to another guy after this was fixed that new this clown. He told me that the pressure lube/charge pump had quit, and the tractor had been running for about 10 years the guy owned it with no feed to the top shaft, It was all worn out and had to be re built.

It turns out somebody cleaned all the filings out the trans changed the oil/ filter and sold it at auction, and kept quiet about the issues. Ask the previous owner if the hyds did funny things when you tried to steer push the breaks and use a spool at the same time. that can be a bad sign there is trouble in the charge pump. steering and stuff is priority on that tractor. if it messes about it means the rest of the system is not getting proper oil supply to the front pump. I hope this tractor was cheap as im kinda frightened what you might find in the filters and stuff.
Good luck Regards Robert

if the charge punp did not work the top shaft would have locked up in less then 5 mins

The answer I got was the tractor might of had a very tiny amount of pressure to keep it going. or more likely it was over full of oil, and splash lubing just enough until it wore and jammed the top shaft between 2 gears. That is what I heard a very experienced John Deere mechanic told the guy that owned the tractor. The pump was totally shot and not enough metal filings in the trans for it to have just happened recently . Like I said I never did it and Sadly this is all I know about it.
Regards Robert
