Technical Notes
The BHT3B turbocharger is a fixed-geometry unit designed for Cummins NT Series engines. Typical configuration may include a standard bearing housing and turbine assembly; verify specific internal components per application. Inspect the old unit for shaft play, oil leaks, and compressor wheel damage before transferring hardware. Confirm that housing orientation and mounting position match the original installation to prevent misalignment. Use OEM reference 3532823 to cross-check physical dimensions and ensure the replacement unit aligns with the engine manifold and exhaust routing.
