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.
It is a connecting rod bolt nut used to secure the connecting rod cap to the connecting rod body. It holds the connecting rod bolt—and thus the connecting rod cap—tightly in place on the crankshaft; it is a critical component of the connecting rod assembly.
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.
However, this must be verified using the ESN (Engine Serial Number), CPL, and the QuickServe catalog before placing the order.
