In this video, I will show you how to replace the SCV couplers on an John Deere 8R tractor. These style couplers have been used for a long time and you can use this repair process for a variety of tractors like the 8030 series, 9030 series, 8R, and 9R tractors. The tractor that I am repairing is a John Deere 8370R that I previously did work on. Took awhile to get the SCV couplers in, so I am just now getting to put them in. Plus, stick around for the bonus content of this video! I will show you how to check grain loss monitor sensors in a John Deere S680 combine.
