    F3680 4wd Engagement advice please

    Yes the coupler that connects to "A" is not stripped, when it is jacked up, I turn the wheels and there is no rotation of "A" , I am wanting to pull "A" out, but not sure if it is as simple as removal of the "C clip" (70) or if I am going to get into a whole mess.... I could go from the Axel...

    F3680 4wd Engagement advice please

    SO need advice on the easiest way to enter this assembly to determine what gear(s) are stripped, I assume they must be... pull the axels or get to it through the driveshaft spline item A. Which direction to attack it from would be appreciated. Although I may wind up taking it from all sides in...

    Well pulled the Drive shaft, nproblem, all splines look good now just trying to figure out the best way to get to the internals to see what part is stripped, let me know if there is an easier way, in the meantime I will try to figure it out, I think I may just start by pulling the axels out...

    F3680 small leak on Deck lift

    Hi guys, my 3680 is spraying Hydraulic fluid from the joint between the Lifter assembly block and the differential case, i thought that maybe the RTV seal had just let go, so I called a Kubota mechanic, he suggested that, likely internal seals were gone somewhere and that I should be prepared...

    F3680 4wd Engagement advice please

    Hi Matt, sorry to drop off the radar, well I feel a bit dumb, I traced the issue with the rear NO Drive, seems like I am getting power to the drive shaft, but it is spinning in the rear axel, so there must be a spline or bevel gear stripped, any idea what the simplest way to get at the gears to...

    F3680 4wd Engagement advice please

    Well you do agree then that if/when I am stuck/spinning front wheels, when in 4WD the rear wheel(s) should also spin OR move the machine if not spinning?

    F3680 4wd Engagement advice please

    Hi Matt, WOW thats EXACTLY what I wanted to see, ... its been raining here a bit, but now I can look for the mechanical shifting. My guess is that the linkage is ok, then I will get it up on stands and test it. You know it may be just a basic limitation of the design, since this is not a...

    F3680 4wd Engagement advice please

    Hi Matt, I got hung up with my Backhoe yesterday, the next step will be to get the machine up on stands and test the driving wheels. All I know is in 4WD mode, I see the front wheels spinning and no spinning on the rear wheels, thats whats driving me nuts, I cant see why when Im stuck and in...

    F3680 4wd Engagement advice please

    Hi Matt, well I did look already since you mentioned it, I thought I would look again more carefully, it was under an obscure description "clutch lock" which kind of makes sense. I hope I am not dealing with 3 burnt out clutches here. Not sure how familiar you are with these, but I notice when...

    F3680 4wd Engagement advice please

    Thanks Matt, I knew where the shifter lever is located, it is what it is linked up to through linkage that I was interested in... any chance of getting a picture of what the lever actuates?

    F3680 4wd Engagement advice please

    Hi all, I purchased 3 F3680 machines out of an auction figuring to sell 2 of them. So they all run perfectly with full operation on everything EXCEPT, all of them seem to not engage in 4wd mode, nor does the AWD assist seem to work. I say this because i test them all through regular cutting...
