Yanmar 4TNV94CHT DPF Filter 2015-2021: OEM 129F01-16400

Effective Soot Filtration for Yanmar 4TNV94CHT Diesel Engines

What is it?
The Yanmar 4TNV94CHT DPF Filter, identified by OEM 129F01-16400, is an emissions aftertreatment component designed for Yanmar 4TNV94CHT diesel engines produced between 2015 and 2021. The Diesel Particulate Filter (DPF) captures soot and particulate matter from the exhaust stream before it exits the system. During regeneration, accumulated soot is burned off to help maintain proper exhaust flow and continued filtration.

Why choose this DPF Filter?
Reliable particulate filtration is important for keeping the diesel aftertreatment system operating as intended. Over time, soot, ash, and other exhaust deposits can accumulate inside the DPF and increase exhaust restriction. Excessive buildup may contribute to frequent regeneration cycles, DPF-related fault codes, warning lights, or other aftertreatment concerns. Replacing a damaged or no longer serviceable filter with the correct OEM-matched component helps maintain proper exhaust filtration and system operation.

Verify OEM 129F01-16400 against the original component and specific engine configuration before ordering.

Installation Notes
Before installation, allow the engine and aftertreatment system to cool completely. Inspect the surrounding exhaust piping, pressure and temperature sensors, clamps, seals, and mounting hardware for contamination, damage, or excessive wear. Install the replacement DPF according to the appropriate manufacturer service procedures and ensure all connections are properly aligned and secured. After installation, check for exhaust leaks, review stored diagnostic codes, and perform any required DPF or regeneration procedures.
