The 169-3374 Injector Sleeve Removal Group is used to remove the brass injector sleeves on 3176 and 3176B Engines, only. This tool group is used with the 9U-6860 Sleeve Replacement Group . The tool group eliminates the tapping and threading operation of the current 9U-6860 Sleeve Replacement Group . The benefits of this method of sleeve removal are easier sleeve removal and little debris that could enter the engine. This tool group uses a crimping die and captured stud similar to the current 3100 Sleeve Removal Tool. This tool group can be used with the cylinder head either on or off the engine.Additional Contact Information

Remove Driving Swage (9) With Crows Foot Pry Bar (12)
Remove the crimping swage from the injector bore. If the tool is stuck in the bore, use a crows foot pry bar (12) in the slot to work out the tool. Many times there will be a small amount of brass caught between crimping swage (9) and the injector bore causing the tool to stick. When the tool is removed, the top of the brass sleeve should be rolled over, trapping sleeve stud (3) inside the injector sleeve.Note: The sharp edge of crimping swage (9) must remain sharp and free of nicks or damage. This tool may be resharpened only on the inside cutting edge. Any sharpening procedure that reduces the OD of the cutting edge will result in poor tool performance and tool sticking.
