More Information
Summary:The invention is directed to a guide bar which includes a fill body in the guide groove thereof. The fill body is disposed in the region of a lubricating bore and bridges the gap between the bottom of the groove and the rakers of the drive links of the saw chain. The fill body raises the bottom of the groove in the region where lubricant is supplied to the saw chain through the lubricating bore. The fill body has a recess formed at the location of the lubricating bore for receiving lubricant therein. With the invention, the take along of the lubricant by the rakers of the drive links of the saw chain is improved thereby reducing the quantity of lubricant which would otherwise be lost. A method and an apparatus for forming the fill body in the guide groove of the guide bar are also disclosed.
