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.
Main crankshaft bearings 0.010” undersize, equivalente a 0,25 mm; Cummins lists part number 4025121 primarily for non-certified 11-liter M11 engines; other catalogs also list it for the L10, ISM, and QSM11 families.
Exact compatibility must be confirmed with the ESN/CPL, as it may vary depending on the crankshaft configuration.
It is fitted to the front end of the crankshaft and serves to absorb and dampen the torsional vibrations of the crankshaft generated by combustion pulses. It normally consists of a heavy metal structure with an internal damping element; it is also marketed as a viscous vibration damper.
Used on C / 6C 8.3 – ISC – QSC – ISL – QSL engines.
Before making a purchase, I always recommend checking the ESN and CPL, or the Cummins OEM catalogue, as the same 8.3 L engine may use different dampers depending on its configuration, power output, year of manufacture and accessory layout.
The game is installed on the crankshaft’s main bearings, it is mainly used in non-certified 11-liter L10 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.
