In today’s emissions-driven environment, the smallest sensors can make the biggest difference. For SANY machines powered by Cummins ISB 6.7L engines, the DEF Head Unit (OEM 160599000138A005, Tamerx part 4310-18-36) is one of those mission-critical yet often unseen parts. A properly working DEF head ensures that your SCR (Selective Catalytic Reduction) system remains precise and compliant—while a faulty one can lead to error codes, derates, or system faults.
-
Monitors the level, temperature, and urea concentration of your DEF (Diesel Exhaust Fluid) to supply accurate feedback to the ECU
-
Controls precise dosing of DEF into the exhaust stream, enabling your aftertreatment system to reduce NOx emissions effectively
-
Built to match the OEM 160599000138A005 specification for plug-in compatibility with SANY / Cummins ISB 6.7L systems
-
Helps prevent emissions faults, warning codes, and engine derates caused by incorrect sensor readings or drift
-
Constructed to handle harsh operating conditions: vibration, temperature cycling, and exposure to DEF chemistry
-
Includes a 40-micron filter to guard against contamination entering the system
-
Backed by a 1,000,000-mile / 1-year warranty when installed properly
When DEF system warnings or derate events show up, the DEF head is often one of the first components to check—but by then, the symptoms have already impacted performance and uptime. Installing the correct OEM 160599000138A005 SANY Cummins ISB 6.7L DEF Head Unit restores your emissions feedback loop, ensures more reliable SCR operation, and guards your system against unexpected failures. In modern diesel emissions, precision isn’t optional—it’s essential.
