This Caterpillar S3BSL-128 Turbo (Part No: 127-5150) is a foundational component within our wholesale Industrial Diesel Engine Parts catalog, specifically configured for the heavy-duty powertrain of Caterpillar 3306 and 3306B series engines. Designed to support fleet maintenance managers and heavy equipment distributors, this unit ensures optimal boost pressure and combustion efficiency for wheel loaders operating in high-cycle mining and construction environments.
Engineered to meet the rigorous airflow maps of the S3BSL-128 specifications, our aftermarket replacement strictly adheres to the original torque rise requirements. Whether you are overhauling a 966F Wheel Loader or servicing a 627F Scraper, this turbocharger addresses common field failures such as shaft play and oil seal leakage caused by thermal stress. It serves as a direct, drop-in solution for the OEM 127-5150 and Reman 0R6689, providing the reliability required to minimize downtime in commercial earthmoving operations.

Technician’s Note: On the 3306 engine, particularly in 966F loaders, the oil return line can become brittle and crack due to engine vibration. When installing the 127-5150 turbo, always verify the integrity of the drain line and gasket; a restricted drain will force oil past the turbine seals, mimicking a turbo failure.

A: No. The 3306 engine has many variations. The 127-5150 is specific to the 3306B/DI engines found in later models like the 966F. Earlier 3306 engines (like in the D6D) typically use the 7N7748 (3LM-373) turbo. Please verify your equipment serial number before ordering.
A: There is no functional difference. 127-5150 is the Caterpillar part number for a new unit, while 0R6689 is the Remanufactured part number. Our Ruich Value replacement is a 100% new unit that interchanges with both.
A: The S3BSL-128 used on these applications is typically a “free-floating” turbocharger, meaning it does not use a wastegate actuator. Boost is controlled by the engine’s fueling and exhaust flow design. The unit comes as a complete assembly ready to install.
We also supply repair kits, nozzles, and cartridges for bulk fleet maintenance orders.
