Tailored Emissions Control: Doosan Bobcat Cummins DEF Head Unit
What is it?
The Doosan Bobcat Cummins DEF Head Unit is a crucial component of the SCR (Selective Catalytic Reduction) emissions system on Doosan Bobcat equipment powered by Cummins ISB or B6.7 engines. It accurately meters Diesel Exhaust Fluid (DEF) into the exhaust stream to neutralize nitrogen oxide (NOx) emissions, while its integrated sensors actively monitor DEF level, temperature, and pressure to ensure precise dosing and stable emissions system operation.
Why choose a Doosan Bobcat–specific DEF Head Unit?
Designed expressly for Doosan Bobcat machinery with Cummins engines, this DEF Head Unit offers perfect compatibility with factory ECM calibration and original harness connectors. It helps prevent SCR faults, limp-mode derates, and system warnings by delivering accurate DEF dosing without needing retrofit modifications. Built for rugged job site conditions, this OEM solution ensures reliable emissions functionality you can count on.
Key Benefits
✅ Plug-and-play fit for Doosan Bobcat equipment with Cummins ISB or B6.7 engines
✅ Precisely regulates DEF injection for optimal NOx reduction
✅ Integrated sensors track fluid level, temperature, and pressure in real time
✅ Engineered to resist DEF crystallization, thermal cycling, and vibration
✅ Helps prevent SCR fault codes, emissions failures, and performance derates
Applications
Ideal for Doosan Bobcat loaders, skid steers, utility vehicles, and compact construction machinery powered by Cummins ISB or B6.7 engines. This DEF Head Unit supports reliable emissions control and SCR system accuracy across stop-start environments and heavy-duty work cycles common on construction sites and industrial operations.
Installation Notes
Before installing, power down the equipment and depressurize the DEF system. Thoroughly clean the DEF tank and adjacent lines to remove residue or crystallization. Install the new unit using OEM connectors and secure fluid and electrical fittings properly. After installation, clear any diagnostic codes and verify DEF dosing and sensor readings through a scan tool to confirm proper function.
Final Thoughts
If your Doosan Bobcat machine is showing DEF-related errors, SCR derates, or inconsistent dosing behavior, replacing the DEF Head Unit with the industry-standard, OEM-compatible version is the solution. Engineered for precision, durability, and proper fitment, it restores proper SCR operation and emissions compliance—available now at Tamerx for fast shipping and trusted performance.
