It is located between the cylinder head and the exhaust manifold; it prevents exhaust gases from escaping.
Cummins specifies the primary use for 10-liter L10 engines; aftermarket catalogs extend the application to the M11, ISM, and QSM families. Final compatibility should be verified using the engine’s serial number.
Rectangular Ring Seal Cummins Engine M11 – Engine ISM – Engine QSM
It creates a seal between two engine surfaces, preventing oil or other fluid leaks at the mounting point. Cummins specifies its primary use on non-certified 11-liter M11 engines; you can also find them on L10, ISM, and QSM engines.
Exact compatibility must be verified using the ESN, as the location and configuration may vary.
Secures the connecting rod cap to the connecting rod, ensuring proper tightening around the crankshaft journal. M12 × 1.25 thread. High-strength steel. Grade: 12.9.
Used on 6C / 6CT 8.3, 6CTA 8.3, ISC 8.3, and QSC 8.3 motors, as well as certain ISL, QSL, and M11 applications.
To ensure full compatibility, I recommend checking the ESN (Engine Serial Number), CPL, and connecting rod number, because there may be different configurations within the ISC/ISL/QSC/QSL/M11 family.
Main Bearing Set STD Cummins Engine M11 – Engine ISM – Engine QSM
The game is installed on the crankshaft’s main bearings, it is mainly used in non-certified 11-liter M11 engines. This corresponds to the STD size. Do not use if the crankshaft has been ground to 0.010, 0.020, 0.030, or 0.040 inches.
Exact compatibility must be confirmed with the ESN/CPL, as it may vary depending on the crankshaft configuration.
