The oil pan gasket seals the joint between the engine block and the oil pan; this is the narrow “early/narrow pan” version, typically with 34 holes.
Primary application for mechanical, non-certified L10 motors with a narrow housing. Some aftermarket catalogs also list it for certain M11 and ISM configurations, but it is not universal for all of these motors.
You must verify the housing type and the motor’s serial number before purchase.
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.
