Description:

PP-3393663 CN Cummins Marine Transmission / Oil Cooler
The PP-3393663 CN Cummins Marine Transmission / Oil Cooler is a copper-nickel (CN) shell-and-tube oil cooler designed specifically for use on Cummins 6BTA marine diesel engines and compatible marine gearboxes.
This cooler removes heat from marine transmission (gearbox) oil by circulating oil through the internal tube bundle while raw seawater flows through the outer shell. Efficient heat transfer is critical for maintaining proper oil viscosity, protecting clutch packs and bearings, and ensuring smooth transmission operation during sustained load, manoeuvring, or high-temperature conditions.

The CN (copper-nickel) construction offers significantly improved corrosion resistance compared to standard copper-brass units, making this cooler well-suited to salt-water and high-duty marine environments. The unit is supplied with sacrificial pencil zinc anodes, which protect internal surfaces from galvanic corrosion and extend service life.

Manufactured to match OEM dimensions, hose sizes, and mounting footprint, the 3393663CN is a direct-fit replacement for the original Cummins 3393663 cooler. It installs without modification to existing raw-water hoses, oil lines, or brackets, and is compatible with common marine gearboxes including ZF, Twin Disc, Velvet Drive, Hurth, and Borg Warner (application-dependent).
