Description Of Change: The new support assembly is now used to help ensure that there is proper alignment with front engine pulleys.

Adaptable To: The new 513-3570 Support As replaces the former 344-0369 Support As. To ensure that the pulleys are properly aligned after completing repairs, use 428-8381 Belt Diagnostic Kit. Any machines built between May 04 2015 and December 2016 has four shims added behind the fan drive. If the front-end accessory drive (FEAD) needs to be replaced for any reason, 513-3570 Support As can be installed and the shims will need to be discarded.

Reference: If a machine is experiencing belt noise after changes have been made, refer to Service Magazine, M0075240, A New Fan Drive Belt and New Belt Route Is Now Used on Certain C9.3 Machine Engines.
