The kit is installed at the front end of the crankshaft, where the shaft passes through the oil pan/front cover. The oil seal keeps the lubricating oil inside the engine while the crankshaft rotates at high speed.
Used primarily in the Cummins L10, M11, ISM, and QSM11 engine families.
Final compatibility must be verified using the ESN (Engine Serial Number) or CPL, because Cummins may use different configurations of the same engine.
It creates a static seal between engine components, preventing leaks of oil, coolant, or pressure at the specific mounting point. The exact location varies depending on the engine configuration.
Cummins specifies that this product is primarily intended for use with non-certified 11-liter M11 engines; aftermarket catalogs also list the L10, ISM, and QSM models. Final compatibility must be verified using the engine’s serial number, as it may vary depending on the CPL and configuration.
