Technical Notes
The S400 turbocharger features a twin-scroll exhaust manifold with two rectangular ports and a single circular compressor inlet. Visible V-band clamps secure the housing joints, while the compressor housing displays a machined, polished finish compared to the cast turbine housing. An actuator or related electrical detail fitting is visible on the side of the housing. Buyers should verify these visible structural features against their existing unit to confirm the S400 configuration matches their Komatsu P139 or SAA6D125E-5-A application.
