Harvest service calls 2 - John Deere 9520 engine knock & 8320R is getting hot.

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 to see the best of ZK MasterTech?
