    Deere 690D hydraulic leak

    So I’ve been doing some thinking and I’m pretty sure it didn’t start leaking this time until it was put into “fast” travel speed…

    Deere 690D hydraulic leak

    So I thought I was finally done with this, ended up replacing both drive motors with rebuilt units. We ran the machine for maybe 30 minutes on Saturday and it did great. We come back to it today, start it up and now hydraulic fluid is pouring out the final drive on the side we just got done...

    Deere 690D hydraulic leak

    I’ll go ahead and order a seal tomorrow and give it a shot… how is the best way to check if the case drain lines are clogged? I’m assuming all the hydraulics feed together then to the return filter?

    Deere 690D hydraulic leak

    Finally getting around to trying to get this fixed… So I’m assuming that with hydraulic fluid getting into the final drive then there is for sure a seal blown on the hydraulic motor ? Or does it seal when it’s in the final drive? What I’m saying is if you removed the hydraulic motor and laid it...

    Deere 690D hydraulic leak

    Thanks for the reply, I’ll check the final drive fluid and report back. Doesn’t sound good though. It’s an old machine but I have enough in it I can’t afford not to fix it…

    Deere 690D hydraulic leak

    Hey all, I’ve got an old 690D LC that has a bad hydraulic leak at the final drive. I was hoping maybe someone here would have some experience with what’s going on. I read in the manual that it’s not necessary to drop the track to get the propel motor off but I’ve never messed with heavy...
