Service Magazine, SEPD0740, 28 June 2004, "New Torque Converter Seal Ring Improves Service Life". The list of affected models has been updated. Replace the article with the following information.Description of Change: The seal ring for the torque converter has been replaced by a new seal ring which is made of a different material. The new material for the seal ring will provide increased service life for the seal.Adaptable To: The new 113-5945 Seal Ring is a direct replacement for the former 7T-2218 Seal Ring. The new 113-5945 Seal Ring is effective with torque converters (S/N: 1KT613) on 789B Off-Highway Trucks, (S/N: 1PT235) on 793B Off-Highway Trucks, and (S/N: 2ST115) on 994 Wheel Loaders. This change is also adaptable to all earlier trucks and 994 Wheel Loaders .Note: If a rebuild kit is used, verify that the kit contains the 113-5945 Seal Ring. The bill of materials that is included with the rebuild kit will identify the part number of the seal ring that is in the kit. A visual inspection of the seal can also be performed. The new 113-5945 Seal Ring has three radial grooves on each side of the seal. The spacing between these grooves is approximately 120 degrees. The former 7T-2218 Seal Ring does not have these grooves. If the rebuild kit contains the 7T-2218 Seal Ring, the 113-5945 Seal Ring must be ordered as a replacement.
