Komatsu PC170LC-11 DOC Filter 2013-2021: OEM 6534-01-0070

Enhance Exhaust Oxidation with a Komatsu PC170LC-11 DOC Filter

What is it?

The Komatsu PC170LC-11 DOC Filter, identified by OEM 6534-01-0070, is a Diesel Oxidation Catalyst (DOC) component intended for compatible Komatsu PC170LC-11 diesel equipment applications manufactured between 2013 and 2021. It uses a catalytic oxidation process to help convert carbon monoxide and unburned hydrocarbons in diesel exhaust into less harmful substances. Proper DOC operation contributes to efficient exhaust processing and supports the function of downstream aftertreatment components where equipped.

Why choose this DOC Filter?

A properly functioning DOC Filter plays an important role in maintaining effective diesel exhaust aftertreatment during demanding equipment operation. Continuous exposure to high exhaust temperatures, oil contamination, unburned fuel, excessive deposits, or physical damage can gradually reduce catalyst effectiveness. Possible signs of DOC-related problems include emissions warning lights, diagnostic trouble codes, increased exhaust emissions, or difficulties with downstream DPF regeneration where applicable. Selecting the correct OEM-matched replacement helps maintain compatibility with the Komatsu PC170LC-11 exhaust aftertreatment system.

Verify OEM 6534-01-0070 against the original DOC assembly, machine serial number, engine configuration, and specific exhaust system before purchasing.

Installation Notes

Before installation, inspect the surrounding exhaust piping, temperature sensors, clamps, gaskets, seals, and mounting hardware for leaks, corrosion, contamination, or physical damage. Check for underlying engine problems, including excessive oil consumption, improper fuel delivery, or abnormal exhaust temperatures, that may have contributed to catalyst deterioration. Follow the appropriate Komatsu service procedures, use the specified replacement hardware, and secure all connections correctly. After installation, inspect for exhaust leaks and verify proper aftertreatment system operation.

Final Thoughts
