ENGINE AR-COMPLETE 1246745 - Caterpillar

3208 Industrial And Marine EnginesDescription of Change: A thrust washer has been added to the fuel pump housing for sleeve metering fuel systems on all 3208 Industrial and Marine Engines. The steel-backed, bronze thrust washer gives a new thrust face for the fuel pump camshaft to prevent housing wear. It also permits easier reconditioning of the fuel system. Formerly, the fuel pump housing had no thrust washer, and it was possible for the camshaft to wear into the housing.
Adaptable To: The 9N5822 Thrust Washer is in effect with engine Serial Numbers 90N52162, 75V7591, 99R248, 1Z1327 and 3Z1252. The 9N5822 Thrust Washer is adaptable to all earlier engine serial numbers if a counterbore and clearance face are machined into the pump housing. Special Instruction, Form No. SMHS7897 has instructions for use of the 6V4068 Tool Group to machine the pump housing and for installation of the washer.
