Seals the gear cover plate. Used with the cast-iron gear cover. Depending on the catalog, it may be listed as “front cover,” “rear cover plate,” or “end plate gasket.”
Main application: 10-liter Cummins L10 engines, especially older, non-certified versions. Some aftermarket catalogs also list it for the M11, ISM, and QSM.
To confirm exact compatibility, it is advisable to check the ESN/CPL, as the application may vary depending on the type of cover.
