Cross section of the hydrodynamic double lip seal.These grooves move the engine lubrication oil back to the crankcase and moves the transmission oil to the flywheel housing as the crankshaft rotates. The double lip hydrodynamic rear crankshaft seal is used where the rear crankshaft seal area may be covered or flooded with oil during operation.
Adaptable To: The new 7C4297 Rear Crankshaft Seal Group is a direct replacement for the former 1W2556 Rear Crankshaft Seal Group.
The 7C4297 Rear Crankshaft Seal Group is packaged with the wear sleeve installed into the seal. DO NOT REMOVE the wear sleeve from the seal for any reason. When the wear sleeve is removed from the seal body, the seal group cannot be used. Attempts to reinstall the wear sleeve will cause damage to the seal surfaces.
