Claim Text:
1. A bearing lubrication tool comprising: a) supply means for delivering a controlled amount of grease, the supply means including a detachable grease cartridge and air cylinder assembly located remotely of the support means, the grease cartridge being installed in the air cylinder and adapted to be emptied of grease when a supply of compressed air displaces a piston in the cylinder that moves the grease to the grease delivery inlet of the support means, b) support means mounted on top of a work bench for locating a bearing in a position where a bearing cage and rollers of the bearing may be lubricated with the grease delivered by the supply means, the supply means having a grease delivery outlet communicating with a grease delivery inlet of the support means by a grease flow passageway, and c) means for controlling the passage of grease through the inlet to the bearing cage and rollers of the bearing, the means for controlling including a valve assembly comprising a cup and a retainer, wherein relative movement between the cup and the retainer causes the valve assembly to assume an open condition for allowing grease to pass through the inlet to the bearing cage and rollers of the bearing.
