6261-81-2700 is documented by Komatsu as a sensor assembly. An engine parts catalog places the assembly in the intake manifold and shows that it includes boost-pressure sensor 6261-81-2710 and its O-ring; this distinguishes it from the separate temperature sensor listed nearby. Exact-number applications include SAA6D125, SAA6D140 and SAA6D170 families, subject to arrangement. Confirm the assembly number, sensor sub-number, connector, pressure range, O-ring, manifold and engine serial.
