Diesel Exhaust Fluid (DEF) 


is an essential component in modern John Deere machinery, helping to reduce harmful emissions and comply with environmental regulations. However, while DEF systems are beneficial for the environment, they can sometimes cause operational headaches for equipment owners and operators. In this blog, we'll discuss some common DEF fluid problems encountered with John Deere equipment and provide tips on how to address them.

1. DEF Crystallization

One of the most common issues with DEF systems is crystallization. DEF is a mixture of urea and deionized water, and if it isn't stored or handled properly, it can crystallize. This can lead to blockages in the DEF lines, injectors, and filters, causing the system to malfunction. When crystallization occurs, it can result in poor engine performance, increased emissions, or even complete system failure.

Solution: To prevent crystallization, ensure that DEF is stored at the recommended temperature (between 12°F and 86°F). Regularly inspect and clean the DEF tank, lines, and injectors to remove any crystallized deposits. Using high-quality DEF and properly sealing the DEF tank after use can also help reduce the risk of crystallization.

2. Contaminated DEF

DEF is highly sensitive to contamination, which can occur if the fluid is exposed to dirt, dust, or even trace amounts of certain chemicals. Contaminated DEF can lead to clogging in the system and damage to components, resulting in costly repairs and downtime.

Solution: Always use clean, sealed containers when refilling DEF and avoid contact with any foreign substances. Store DEF in a clean, dry area and keep the container tightly closed when not in use. If contamination is suspected, it's essential to flush the DEF system and replace the fluid with a fresh, uncontaminated batch.

3. DEF Quality Issues

Low-quality or improperly mixed DEF can cause a range of issues, from decreased performance to system malfunctions. DEF that doesn't meet the required standards can fail to reduce emissions effectively, leading to regulatory compliance issues.

Solution: Only purchase DEF from reputable suppliers who adhere to ISO 22241 standards. Regularly check the DEF concentration and quality using DEF testing kits to ensure it meets the necessary specifications.

Conclusion

While DEF systems are crucial for reducing emissions in John Deere equipment, they can present challenges if not properly managed. By understanding these common DEF fluid problems and taking proactive measures, you can minimize downtime, maintain optimal performance, and ensure your machinery remains compliant with environmental regulations.
