What is it?
The TICO Tractors Cummins DEF Head Unit (OEM 20086-9) is a control assembly designed for diesel material-handling or terminal-tractor applications using a Cummins engine and DEF (Diesel Exhaust Fluid) after-treatment system. It monitors DEF level, temperature and flow, and manages dosing into the Selective Catalytic Reduction (SCR) system to help reduce NOₓ emissions. (tamerx.com)

Why Choose the TICO Tractors Cummins DEF Head Unit (OEM 20086-9)?
This head unit is manufactured to match TICO’s or the original equipment manufacturer’s specifications for the DEF system—mounting geometry, connector layout, fluid ports and sensor configuration are designed for direct fit. Using an OEM-listed unit helps ensure proper integration, avoids compatibility issues and supports reliable after-treatment function in heavy-duty duty-cycle environment. (tamerx.com)

Key Benefits
✅ OEM-Compatible Fitment: Designed for mounting, fluid and sensor interfaces that align with original TICO/Cummins systems.
✅ Accurate DEF System Monitoring: Monitors fluid level, temperature and flow to support correct SCR dosing and emissions compliance.
✅ Industrial Duty Readiness: Built for harsh operating environments such as terminal tractors, yard trucks or material-handling machines.
✅ Reduced Risk of System Errors: Properly matched head unit helps prevent DEF-system faults, WARNINGS, or engine derates.
✅ System Longevity Support: When the DEF system operates correctly it helps protect the SCR catalyst, sensors and exhaust hardware from over-stress.

Applications
This head unit is intended for TICO-branded tractors or terminal vehicles powered by a Cummins engine with a DEF system and the OEM part number 20086-9 configuration. It’s suited for commercial operations, terminal yard duty, heavy equipment and other environments where emissions control and operational reliability are key.

Installation Notes
Professional installation is recommended. Begin by verifying the engine model, chassis configuration and matching the OEM part number 20086-9. Before removal, power down the DEF system safely and relieve any pressure in fluid lines. Disconnect wiring, fluid hoses and coolant connections if applicable. Remove the old head unit carefully, paying attention to sensor ports, gaskets and connector integrity. Clean the mounting area thoroughly and inspect for seal or gasket damage; install the new unit with fresh gaskets or seals. Torque bolts to manufacturer specification, reconnect all sensors and fluid lines properly, then clear diagnostic fault codes. After installation, monitor system behavior—check DEF level readings, flow response, and confirm no derates or fault codes appear.

Final Thoughts
For heavy-duty equipment operating in terminals or industrial settings, proper after-treatment control is essential. The TICO Tractors Cummins DEF Head Unit (OEM 20086-9) provides a factory-matched solution built to keep your DEF system accurate, emissions compliant and your operation running with minimal interruption.
