Abstract:
Embodiments provide for a lubricant delivery system that includes a saw chain guide bar, such as a harvester bar, and an integrated lubrication channel insert that is insertable into the saw chain guide bar. Oil, grease, or other lubricant can be passed to the chain to the groove bottom to lubricate the chain during use though the lubrication channel insert, as disclosed herein. The lubricant enters the groove via the lubrication channel insert opening into the guide groove in the region of the groove bottom. The lubrication channel insert is coupled to the guide bar and is fed from a transverse lubrication channel lying below the groove bottom. Also provided is a lubrication channel insert.
