New engine, power train, and monitoring systemsoftware needs to be installed on certain 953C, 963C and 973C Track TypeLoaders. It will improve the performance of these machines, especiallywhen turning under a load or at high speed. The 953C and 963C turbo oilsupply line must be changed in conjunction with the new engine software.A 963C and 973C motor POR adjustment can be done at the same time. Thiswill also improve steering performance but it is independent of the softwarechanges. For more information see Service Magazine dated August 2, 2004(SEPD0745).AFFECTED PRODUCT
