Dear Mr./Ms. Nikolaenkov,
Before proceeding, purchasers should be aware that publicly available parts databases contain conflicting information regarding this part number. A limited number of aftermarket parts listings associate5 6B-02-3A101 with a “ Muffler,” but the same listings contain inconsistent technical data, including a bearing category classification and manufacturer name that do not correspond to an exhaust component . No official Komatsu Parts catalog entry confirming this exact number as an HM400-3M0 muffler was located in available search results. Buyers are strongly advised to verify 56B-02-3A610 against the HM400-3M0 Parts Manual using the machine serial number (5001 and up) before ordering, and to confirm the correct part number through an authorized dealer.
Assuming the part number corresponds to the HM400-3M0 exhaust muffler, this component serves as the primary noise attenuation and exhaust gas routing device in the truck’s aftertreatment system. The HM400-3M0 is a 40-tonne payload articulated dump truck powered by a SAA6D140E-6 engine rated at approximately 350 kW, designed for demanding off-road hauling in quarries, mines, and construction sites . The exhaust system must manage high gas temperatures and flow volumes under continuous load while meeting noise regulations and maintaining backpressure within engine manufacturer specifications.
