Papa-Alpha #10 is the product number for this complete three-piece set. These Cessna numbers are references, not a representation that this is an original Cessna product. Aircraft applicationHistorical Cessna service manual D991-3-13 describes use of the three-piece set for main landing gear rigging on the 1971 Cessna 177RG Cardinal RG, serial numbers 177RG0001 through 177RG0212. The same historical manual also calls for the SE997-3 gauge in the rigging procedure for 177RG0213 through 177RG0282. The historical R182/TR182 manual calls for an SE997-1 or SE997-2 shim in a main-gear check beginning with R18200685. Those additional references concern individual components and do not establish use of all three pieces on every aircraft. Confirm the current aircraft-specific maintenance manual, serial number, and configuration before selecting or using the set. Other models and serial ranges have not yet been verified. Intended for use by qualified maintenance personnel in accordance with applicable maintenance data.
