Main Bearing Set Standard Cummins Engine L10

Main Bearing Set STD Cummins Engine L10

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.

Oil Cooler Rectangular Seal Cummins Engine L10

Rectangular Ring Seal Cummins Engine L10

It is recommended for use in the lubricating oil cooler area of 11-liter Cummins M11 engines, particularly non-certified automotive versions. Normally, two engine gaskets are required when assembling the oil cooler.

The official Cummins website primarily lists it for the M11, but specialized catalogs also confirm compatibility with the L10, ISM, and QSM.

To ensure a successful purchase, it is still advisable to check the ESN and CPL, as the installation may vary depending on the engine configuration.

The same ISC/ISL family can use different bowls depending on the application—road, industrial, or marine—or the position of the filter housing.

The ESN remains the most important check,
because the same engine model can be fitted with different
parts depending on the year of manufacture or the CPL.

Gaskets

Oil Pan Gasket Cummins Engine L10

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.

Oil Pan Gasket Cummins Engine L10

It is installed between the engine block and the oil pan. It prevents lubricating oil from leaking out and dust or contaminants from entering the lower part of the engine.

For the L10 engine, the Mechanical, CELECT, and Gas versions are listed. Compatibility with other engines, such as the M11, ISM, and QSM, must be verified using the engine serial number (ESN), as different oil pans may be used.

Lubricating Oil Pump Cummins Engine L10

It draws oil from the sump and circulates it under pressure to lubricate the bearings, crankshaft, camshaft, and other internal components.

Engine applications commonly associated with Cummins, which primarily confirms its use in the M11, while aftermarket catalogs also list the L10/ISM/QSM.

For precise application, however, I recommend verifying using ESN/CPL.

Front Crankshaft Seal Kit Cummins Engine ISL – Engine QSL

Front Oil Seal Kit Cummins Engine ISL – Engine QSL / QSL 9

The kit is fitted to the front of the crankshaft, at the front gear housing/front cover. Its main function is to prevent engine oil from leaking around the crankshaft whilst it is rotating. The oil seal is normally made of an oil- and heat-resistant elastomer with a metal support ring.

Used on the 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL, QSL / QSL 9 engines.

Final compatibility must always be checked using the engine’s ESN and CPL, or the Cummins OEM catalogue. Within the QSL family, there may be variations depending on the year, configuration and CPL; therefore, the engine family alone does not guarantee 100% suitability.
