In this video we continue repairs on the John Deere S680 hydraulic nightmare. We switch gears and go into replacing the hydraulic oil cooler and while we got the upper shields off, might as well fix the exhaust manifold gasket that's blown out! With this combine, you never know what you'll run into! #johndeere #johndeerecombine #s680 Sloan Implement apprenticeship program: https://www.sloans.com/apprentice-program Careers with Sloan Implement: https://www.sloans.com/career Sloan express: www.sloanex.com
