In this video, Patrick has a 9520R with a nasty knock in the engine and I hit the road to go finish up the 8320R fan drives. Got the parts in to install new dry style fan drives on an older Teir 3 8R 9.0L engine. Customer is still complaining on the tractor getting hot so we try a set of thermostats. Then I go back to the shop to see what Patrick has found… #johndeere #johndeeretractor #milwaukeetools #snapontools #matcotools Want some ZK merch? null Check out my Amazon store front! https://www.amazon.com/shop/zkmastertech Want a career with Sloan Implement? https://www.sloans.com/career
