It is installed between the connecting rod and the crankshaft’s connecting rod journal. It creates a lubricated sliding surface that allows the connecting rod to rotate on the journal, reducing friction and wear and withstanding the loads from combustion. Some parts use a copper/lead-tin tri-metal structure, with a nickel barrier and a top layer of Babbitt.
For installation on Cummins L10, M11, ISM, and QSM/QSM11 engines.
Mainly for uncertified 11-liter M11 engines; for L10/ISM/QSM engines, it is advisable to check the ESN and CPL before confirming compatibility.
Located inside the engine block, between the piston and the crankshaft. Its function is to transfer the force generated by combustion from the piston to the crankshaft. Made of high-strength forged steel.
It is primarily installed on Cummins L10 engines, as well as on M11 and ISM engines.
Final check before acquisition: ESN + CPL, especially to distinguish between drilled and non-drilled configurations and the corresponding casting.
