Wayne Truck & Trailer: Your Solution for EGR and DPF System Repairs!

Semis and heavy-duty trucks can be complex vehicles with various systems to keep them running smoothly.

The EGR (exhaust gas recirculation) and DPF (diesel particulate filter) are two such systems.

The EGR system is designed to reduce emissions by recirculating some of the engine’s exhaust gas back into the engine cylinders, where it is burned again.

The DPF system, on the other hand, captures and stores harmful particles that would otherwise be released into the air.

Both systems are essential for compliance with emissions regulations and can be a hassle to repair or replace.

That’s where Wayne Truck & Trailer comes in. Our experienced technicians are well versed in repairing and maintaining all types of heavy-duty vehicles, including those with EGR and DPF systems.

Exhaust Gas Recirculation (EGR) Repair

One maintenance task that is often overlooked but critical to the engine’s health is the EGR (Exhaust Gas Recirculation) system.

This system helps to reduce emissions by recirculating exhaust gases back into the engine to be burned again.

However, the EGR system can become clogged or damaged over time, leading to decreased fuel efficiency and performance issues.

Repairing or servicing the EGR system involves cleaning or replacing the components, such as the EGR valve or cooler.

It is important to promptly address any issues with the EGR system to ensure that your trucks are running efficiently and meeting emissions standards.

Diesel Particulate Filter (DPF) Repair

When it comes to maintaining the performance of heavy-duty trucks and Semis, DPF repair and service cannot be overlooked.

DPF stands for Diesel Particulate Filter, an essential vehicle exhaust system component.

It traps harmful soot and particulate matter before it is released into the atmosphere.

Over time, the DPF system can become clogged or malfunction due to prolonged use, engine problems, or contamination.

This is where DPF repair and service come in. The process involves inspecting, diagnosing, cleaning, and repairing or replacing faulty components.

Proper maintenance of the DPF system can help promote peak performance and prolong the vehicle’s lifespan while reducing carbon emissions.

What Our Customers Are Saying About Us

I had a roadside breakdown on I-70 due to a coolant fitting failure. They were easy to work with and the tech had made this same repair previously on other trucks. The fitting is one that connects the engine head to heater core. They had to stop by a Paccar dealership (in Dayton?) to get the part and then make the roadside repair. They gave me a price estimate before heading my way and the final bill was somewhat less since I didn’t need as much coolant as estimated. Easy to work with, I would recommend them and use them again myself – if needed. My only complaint was that they didn’t open until 8a. I would’ve given 5 stars if they could have rolled at 6a. The parts dept at Paccar opened at 7a so it wasn’t a huge impact on the schedule.

I had a bad miss on my Volvo VN with a Volvo D13 engine in it. They had the software to diagnose the problem and were able to replace the bad injector. I was back on the road the same day. Last time I had this problem I took it to a Volvo dealer, and they took a week before e they would even look at it.

Truck Service

My family and I have been traveling for the past 3 weeks in the RV. We have had terrible luck up until this point with our RV. Needless to say, many tows and service repair work. This business has gone above and beyond. They were completely understand, sympathetic, and willing to help until they figured out what the problem was! We had our dogs, kids, cat, and extended family there with us all day. There were no problems with that. We felt comfortable and at ease here! I would highly recommend this shop to anyone. The quality, communication, and price was just what we needed! Thank you to all who helped!

Wayne Truck & Trailer came to my rescue when it came to an unusual situation with a tire on my Truck. After sitting at a Loves in Dayton for 4 hours waiting for my turn to have this tire fixed, only to find out they didn’t have the size I needed. After looking around, Wayne Truck & Trailer came through!! Cody really took care of our situation, and the company was well pleased.

Thank You, Cody and Wayne Truck & Trailer, for everything. Please keep up the great work.

Our motorhome broke down in Greenville, OH and their techs spent a few hours fixing it. They were pleasant to deal with and got us back on the road as quickly as they could.

Harlie Wullner

“My company travels all over the US with trucks and enclosed trailers. We had two equalizer straps tear off of the bolt/leaf spring on one side. Google suggested Wayne Track and Trailer nearby. Great choice! Norm was excellent at the front desk and the guys in the shop were very helpful and knowledgeable. They were able to get us repaired and back on the road in a just a couple of hours. Highly recommended!”
