Rear end of the crankshaft, flywheel side. Rear oil seal with wear ring, dry-clutch application, Non-REPTO. Prevents oil leakage between the crankshaft and the flywheel housing.
Final compatibility must be verified using the engine serial number, because the same M11/ISM model may use a different oil seal depending on the flywheel, clutch, and REPTO configuration.
It is installed between the engine block and the oil pan. It prevents lubricating oil from leaking out and dust or contaminants from entering the lower part of the engine.
For the L10 engine, the Mechanical, CELECT, and Gas versions are listed. Compatibility with other engines, such as the M11, ISM, and QSM, must be verified using the engine serial number (ESN), as different oil pans may be used.
Seal the component joint to prevent oil or engine fluids from leaking. Cummins primarily uses it for 11-liter M11 engines, but it is also installed in L10, ISM, and QSM engines.
To confirm the exact application, you should check the motor’s ESN/CPL, as it may vary depending on the configuration.
