Crawler Tractor track adjuster valve / checkball. This is the valve that screws into the track adjuster for adding grease to the track tensioner. Often times with age, these valves no longer seat properly and have to be replaced. Can combine shipping w/ other items (manuals, seal kits etc). Ships nicely w/ a track adjuster seal kit.
