I bought a used 1840 case 1994 decent shape but after using it for awhile i noticed a leak, so i took it to a dealer and they told me its leaking is most likely leaking from my hydraulic motors and would replace both for 5000. I dont want to put that much into it and was wondering if there was anything out there that you can add to recondition the seals or could i buy and replace motors my self............please help. Thanks rockman.
