Case 1021F 1121F Tier 4 Wheel Loader Service Repair Manual
- Wheel loaders built in 2011 and after can be equipped with Selective Catalytic Reduction (SCR) engine exhaust emission control system. With this system, the engines operate as efficiently as possible. During normal operation the diesel engine generates certain pollutants. Federal law has regulated the levels of these exhaust components that a vehicle is allowed to emit. Pollutants generated in the normal operation of the engines require after treatment.
- The SCR system converts the pollutants to harmless nitrogen and water. A diesel engine operates most efficiently at higher combustion temperatures. Unfortunately, the higher combustion temperatures generate increased levels of nitrogen oxides (NOx). A sensor determines the NOx level in the exhaust stream and reports this information to the Engine Controller.
- To reduce the NOx level the system adds a urea based Diesel Exhaust Fluid (DEF) to reduce the pollutant. The NOx sensor monitors the exhaust to assure the system meets regulations. An alarm sounds and a warning displays on the Advanced Instrument Cluster (AIC) if the system malfunctions. Operator Cautions DEF fluid mishandling causes SCR system problems.
- It is preferable to dispense DEF directly from factory containers. If refillable containers are required to handle DEF, make sure that it does not have traces of other contaminating liquids. Water and oil do not mix.
- Petroleum contamination causes problems. Make sure that dirty containers are not used. Replace the tank filler cap after filling. Dirty fluid causes premature filter plugging.
