--------------- END SUPPLEMENT ---------------
Description of Change: Improved final drive duo-cone rings are now used. The improved seals maintain their performance through a much wider range of temperatures, and perform significantly better in cold temperatures, as compared to the former ring seals. This significantly reduces the incidences of seal leaks when machines are operated in cold or arctic conditions. The seals visually appear the same, and can only be distinguished by the part number and the greater flexibility in cold temperatures.
Adaptable To: The improved 163-7373 Seal replaces the former 9G-5348 Seal and is part of the new 163-7368 Duo-Cone Seal Group. The new seal is effective with Challenger 65E (6GSxxx), Challenger 75E (6HSxxx), Challenger 85E (6JSxxx) and Challenger 95E (6KSxxx) Agricultural Tractors. The improved 163-7373 Seal or the 163-7368 Duo-Cone Seal Group are retrofittable to all earlier Tillage Challengers Agricultural Tractors that are equipped with either 9G-5347 or 9W-6630 Duo-Cone Seal group.
