EGR Systems

Signs of EGR Failure

Exhaust Gas Recirculation (EGR) systems are crucial for reducing NOx emissions. However, they can fail due to several reasons:

Clogging: The EGR valve can become clogged with soot and carbon deposits, leading to poor engine performance and increased emissions.

Sticking Valve: A sticking EGR valve, either open or closed, disrupts the flow of exhaust gases, affecting the engine's air-fuel balance.

Sensor Malfunction: EGR sensors can fail, sending incorrect data to the engine control unit and causing efficiency and performance issues.

EGR Repairs Process

Effective EGR repairs involve:

Valve Cleaning/Replacement: We meticulously clean or replace the EGR valve, ensuring unobstructed exhaust gas flow.

Sensor Checks and Replacement: Our mechanics test and, if necessary, replace faulty EGR sensors to maintain accurate control.

System Inspection and Maintenance: We conduct a thorough inspection and maintenance of the entire EGR system to prevent future failures.

DPF Systems

Signs of DPF Failure

Diesel Particulate Filters (DPF) trap soot from exhaust gases. Failure signs include:

Decreased Fuel Efficiency: A clogged DPF forces the engine to work harder, reducing fuel efficiency.

Increased Oil Consumption: Blocked DPFs can lead to increased oil consumption and potential engine damage.

Warning Lights: The DPF warning light indicates a need for immediate attention to prevent further complications.

DPF Repairs Process

Our DPF repair services include:

Deep Cleans: We perform thorough deep cleans to remove soot and ash build-up in the DPF.

Forced Regeneration: In cases of severe clogging, we conduct forced regeneration to burn off excess particulate matter.

DPF Replacement: When necessary, we provide expert DPF replacement services to ensure optimal vehicle performance.

FAQs

How do operators minimize active regeneration duration during agricultural duty cycles?

Maintain moderate to high loads to support passive burn-off, reduce idling, and ensure regenerations complete. Check for leaks in the intake and exhaust, verify the health of EGR and sensors, and properly manage ISO-compliant DEF to keep the SCR efficient.

What documentation best supports a clean DOT emissions inspection?

Provide recent PM records, scan reports showing no active fault codes, and proof of successful DPF regeneration. Include receipts for emissions-related parts, calibration or software updates, and DEF quality management. Organized evidence helps inspectors verify compliance quickly, reducing audit time.

Second repair to my 30HP Kubota at Hex6. Axle issue first and steering second. Timing was good to complete considering their shop load. Cost in line or better than other options. Good staff. Most pleased overall.
Wow, what a great Company. Caleb was in constant contact and the bill came out much less than the estimate! The technician was on time, very knowledgeable and the job was done quickly. I will use them every time for my tractor work! Thanks Hex 6!
Hex 6 did a great job on my work truck. They did a full in frame rebuild. The service was fast and my truck has never run better. I took it back for regular schedule PM and they had me in and out the next day. Will only use them moving forward!!
