The Ruich Value 127-5150 is a precision-engineered Schwitzer S3BSL-128 turbocharger for the Caterpillar 3306B 10.5L engine. Built with an Inconel 713C turbine wheel to resolve oil seal leakage, it fits CAT 966F loaders and 627F scrapers. Factory direct wholesale available.
In high-cycle quarry and infrastructure projects, the induction system’s efficiency directly dictates the productivity of the 10.5L 3306B powerplant. Ruich Value delivers the Caterpillar 127-5150 turbo, a heavy-duty S3BSL-series unit designed to restore the boost response and fuel economy of your 966F wheel loader turbo applications. Manufactured to uphold Caterpillar’s rigid QDR (Quality, Durability, and Reliability) standards, this turbocharger provides the sustained pressure ratios required for intense bucket-loading and earthmoving cycles.
Long-term heavy equipment service often reveals vulnerabilities like turbo oil seal leakage and significant shaft play. These issues are frequently caused by thermal stress cracking in the turbine housing or carbon contamination within the journal bearing oil galleries. Our replacement 127-5150 units feature a turbine wheel cast from Inconel 713C alloy, offering superior resistance to the extreme temperatures of a turbocharged 3306B. Every core undergoes dynamic VSR balancing at 150,000 RPM, definitively eliminating the vibrations that lead to premature seal failure and black exhaust smoke.
For global parts distributors and fleet managers in the Caterpillar 3306B turbocharger market, precision fitment is mandatory. This direct replacement for 127-5150 (fully interchangeable with 167972 and 0R6981) is factory-calibrated to match the original Schwitzer flow maps. Whether you are overhauling a 970F loader or a 627F scraper, our wholesale Caterpillar head and turbo inventory provides a factory-direct path to reliability, bypassing dealership lead times and ensuring your industrial diesel assets return to peak operational torque.

The primary symptom of turbo oil seal leakage is thick blue-grey smoke from the exhaust, especially during acceleration. This occurs when oil bypasses the journal bearing seals into the hot turbine housing. If left unaddressed, this leads to shaft play and eventual compressor wheel strike. Replacing the unit with our 127-5150 turbo restores balanced oil pressure containment and induction purity.
No. While both are used on the 3306 engine, the 7N7748 is a 3LM-type turbo for older, non-intercooled arrangements. The 127-5150 (S3BSL-128) is a more modern frame specifically for intercooled 3306B engines found in 966F loaders. They have different flange orientations and compressor outlet diameters. Always verify the S3BSL-128 turbo 127-5150 part number on your original tag before ordering.
Premature failure is often caused by oil starvation during the first 5 seconds of operation. You must “oil prime” the 127-5150 by filling the oil inlet with 20cc of clean engine oil and manually rotating the compressor wheel before connecting the lines. Additionally, ensure the oil feed and return lines are free of carbon deposits (coking) to maintain full hydrodynamic lubrication at high RPMs.
