PUMP GP-VANE 9J5055 - Caterpillar

3500 Commercial Engines Equipped With An Air Starting MotorDescription of Change: A new bowl lubricator has been added for air starter lubrication. It is recommended that the bowl lubricator be used with a non-detergent SAE 10W oil. This oil is more compatible with the composite-material vanes in the air starter. The former shot lubricator used fuel as a lubricant. This could result in premature wear to the composite-material vanes in the starter. In some cases this high pressure fuel could also leak past the seals and over-lubricate the air starter. If the shot lubricator is not working correctly in its current application, the bowl lubricator is recommended. Adaptable To: The new 119-6284 Lubricator Group (Bowl) replaces the former 4N-7556 Lubricator Group (Shot). The former lubricator group is canceled. The new bowl lubricator can be adapted to any shot lubricator currently in use. The new lubricators are part of the 7C-2971, 7C-4167, and 7C-5104 Air Starting Motor Groups. It is also part of the 7W-9269 Air Lines Group. Chart A identifies the effectivity of the new lubricator group. Chart B identifies the components to be removed before installing the new bowl lubricator group. Chart C and the illustration identify the components required to install the bowl lubricator. When installing the bowl lubricator system, use 5P-3413 Pipe Sealant on the threaded ends of pipe fittings. When installing the pipe nipple into the bowl lubricator use a 6V-6640 Gasket Maker on these threads.
