One New Aftermarket Replacement Check Valve Fits John Deere Crawler Dozers

This aftermarket replacement check valve fits the track adjuster assembly on Fits John Deere crawler dozers. The valve screws into the track adjuster and controls grease flow to the track tensioner, keeping proper track tension. Over time these valves can fail to seat properly, requiring replacement to maintain correct track tension and prevent grease loss.
