PSP FOR WATER PUMP SEAL FAILURES IN 3406...92U, 3406B...7FB TRUCK ENGINES - MAILED US AND CANADA, COSA, TRUCK TEPS
  The information supplied in this service letter may not be valid after the termination date of this program.   Do not perform the work outlined in this Service Letter after the termination date without first contacting your Caterpillar product analyst.
PRODUCT SUPPORT PROGRAM FOR WATER PUMP SEAL FAILURES IN 3406 (92U) AND 3406B (7FB) TRUCK ENGINES, 1361, PS0322 U-107 O-56 TT-8 This Service Letter replaces the September 11, 1986 Service Letter (PSO231). Cross out the September 11, 1986 Service Letter. The September 11, 1986 Service Letter was not distributed to dealers in Caterpillar Overseas S.A. This Program can only be administered after a failure (leak) occurs. A leak is indicated when there is a continuous and prolonged trickle that causes puddling under the truck when it's parked. A small amount of coolant leakage across the face of the seal is normal and necessary to provide lubrication. When reporting the repair, use "PS0322" as Part Number and "7755" as Group Number. Although products in the field are to be administered as described above, dealers should purge parts stock immediately. Termination Date
August 31, 1989

The water pump used on the Affected Product has caused customer dissatisfaction because of a short service life of the water seal. Failures of the water seal can be caused by the use of high silicate antifreeze and/or by a too high concentration of corrosion inhibitors. The customer is expected to maintain the cooling system as recommended in the Operation and Maintenance Management Guide.
