The engine water pumps need to be inspected on certain D11R Tractors; 776D Tractors; 777D and 793C Trucks; 992G Wheel Loaders; and 3508, 3508B, G3508, 3512, 3512B, G3512, 3516, 3516B, G3516, G3524, and G3532 Engines. Water pumps that do not have a "W" stamped on the pump to indicate that they have been reworked previously need to be disassembled to clean the taper where the impeller mounts. If the taper is not properly cleaned before tightening the nut the impeller can turn on the shaft and result in overheating.
