Perkins 198636170 Rear Crankshaft Oil Seal

The Perkins 198636170 rear crankshaft oil seal is a precision-engineered sealing component designed for the rear main bearing of Perkins 100 Series and 400 Series diesel engines. It features a fluoroelastomer (FPM) sealing lip bonded to a steel case with a garter spring for consistent radial load. The seal dimensions are 90 mm inner diameter, 154 mm outer diameter, and 13 mm width. This part prevents oil leakage and excludes contamination in heavy-duty industrial and construction equipment applications. It serves as a direct replacement for Caterpillar 156-6973, Wilson 987-848, Shibaura SBA198636170, and Volvo Penta VO198636170.
