    John Deere 2630 Split, troubles, etc

    Thought I would make a post about my adventure with this 2630 tractor. I got it for a really good price knowing it needed work. I guess I didn't realize the extent of the work though. I am no mechanic at all, I did work for CAT for a while. I grew up driving similar tractors, probably since around 5. This is the first one I actually purchased myself.

    Tractor didn't even start when delivered, they rolled it off a rollback I think because the gravel was pushed away. Eventually, I discovered a variety of electrical issues, basically rewiring the entire machine.

    Shifter had serious slop. Discovered the parking assist kit add-on, this tractor had the kit added but still had the old snap rings. Whatever, ordered the right kit of snap rings, problem solved. Could have been worse, seeing how the aluminum shifter cover is busted in a few places.

    Finally got it running, changed all fluids. Hydraulic inlet screen wasn't really as bad as I expected, but wasn't great either. It was probably 40-50% clogged.

    Eventually I got around to using it only to discover how destroyed the clutch was. Tractor wouldn't pull up a hill in low gear, engine running fine. So I pulled it in the garage and split it myself.

    Pilot bearing was destroyed, clutch disk had seen better days, entire inside of housing looked like an oil bomb went off.

    Discovered the vibration problem, no balancer shafts??!? Previous owner removed them? My guess is they got robbed for another machine. That will be another repair for another day...

    New injectors, fuel transfer pump, replaced a few fuel lines... Checked static timing on fuel pump and freaked out because I didn't see the governor weight basket timing mark. Went through the whole process of removing the pump only to eventually find out Stanadyne updated the weight basket design, the new design did not have a timing tick mark.

    Currently working on the rockshaft rebuild. I discovered oil spraying out the filler cap while running. My hope is fixing this will fix a number of hydraulic problems, but if not I am prepared to hook gauges up to find the issues. I also discovered a gash knocked out of the cylinder bore of the lift cylinder... I hope this won't cause issues, I'm basically out of money at the moment so purchasing a valve housing is out of the question for now.

    Small little update, with the help of flywheight and Tx Jim - the two valve plugs, mine had a back-up ring in addition to the o-ring on the outer sealing surface. The rebuild kit as well as the technical manual do not show that back-up ring, only o-ring. TX Jim pointed out that some point in manufacturing, they switched to the single o-ring design I believe as well as a different valve cap. In my case, I am going to have to pull the caps back out to put the back-up ring back in - not sure yet how I am going to do that, they fit much tighter now that it has a new o-ring in...

    Thread here on the issue: https://www.greentractortalk.com/for...raulics-4.html

    These are the kinds of things that I guess you cannot foresee happening unless you have experience which I do not have. There is certainly nothing in the literature about the back-up ring, so I assumed they replaced the backup ring + o-ring design with a single o-ring.

    Also found a picture of the old clutch "finger" as I call it vs the new one. You can see how much wear it has.

    one question. In the opening of this thread you state "I am no Mechanic". If you aren't I don't know what you would call yourself. You may not be a professional mechanic but you are a mechanic. Good luck it nice to follow this

    I appreciate that.

    I used to work for CAT, then decided I didn't want to turn wrenches every day all day. So I went back to school, got my mechanical engineering degree, and just got my professional license about 2 weeks ago. I like tinkering but I'm not cut out for it.

    Another thanks to TX Jim. Small issue, my cutter would randomly drive up (3pt hitch). Turns out, all it was, worn bevil washers at the lift control lever. Cut a spring to replace them, all should be good now.

    Waiting on the Piston o-ring and Teflon seal then it all goes back together. Since there seems to be interest, I'll keep posting pictures and updates. I made some videos too, if anyone was curious. Mainly like to talk about the things that aren't in the technical manual...

    No updates yet...

    Few more pictures though, looks like something catastrophic happened at some point. It appears someone welded one of the pins on the load control arm. Upon investigation, I suspect something happened (likely overloading the machine) where this pin and/or something else broke off and fell in the final drive housing. I can see where something pressed against the bolts holding the differential together, that will be difficult to get apart now if I ever need in that...
