2N2560 Water Pump Seal fit Caterpillar — SKU 2N2560

The 2N2560 is a lip-type water pump seal for Caterpillar equipment. It is used in water pump applications on Caterpillar engines, generator sets, ship equipment and industrial engine models listed below. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The seal is identified by the Caterpillar equipment part number 2N2560 and the hyphenated number 2N-2560. The application data includes several Caterpillar engine and equipment configurations, so the machine model and existing seal number should be checked before installation.

Fitment

The 2N2560 water pump seal is listed for the following Caterpillar equipment models and application groups:

• Engine and generator kit: D379B, D398B, D399
• Ship equipment: D379A, D379B, D398A, D398B, D399
• Industrial engines: D379, D379B, D398, D398B, D399, G379, G379A, G398, G399

For industrial engine applications, the listed models include the D379, D398 and D399 engine families, as well as G379, G379A, G398 and G399 configurations. The D379B and D398B models are listed in more than one application group, including engine and generator kits, ship equipment and industrial engine applications.

Application information is organized by equipment category because the same Caterpillar model designation may occur in different machine or engine configurations. Fitment should therefore be confirmed against the specific equipment model, water pump assembly and number of the seal being removed.
