New Water Pump Assemblies Use An Improved Seal Assembly{1361}
Usage:
613B Tractors;
225 Excavators;
3208 Industrial, Truck and Marine Engines
Description of Change: New water pump assemblies, which use an improved seal assembly, are used on the above models. The new seal assembly has a larger bend radius on the sleeve. Also, Loctite is used on the outer surface of the bearings to prevent their rotation in the housing. If a bearing outer race turns in the housing, it can cause the bore to become oversize.
Adaptable As: Direct replacement.
