Function of this part

The aftertreatment system treats exhaust gases after they leave the engine using components such as the DOC, DPF, and SCR catalyst. It controls soot and NOx emissions by trapping particulates and converting harmful gases into less harmful compounds.

Why this part matters

These components are central to emissions compliance on modern diesel trucks. Problems in the aftertreatment system can cause frequent regens, power derates, and down-time until the fault is corrected.

About the brand

PACCAR components support both Kenworth and Peterbilt trucks with OEM-grade fit and performance.

Fitment & usage

Used OEM parts are a smart choice for controlling repair costs while still using original-equipment components. Always match the OEM part number(s) listed to your existing part, and consult your service manual, dealer, or technician if you are unsure about fitment.

Note: Because this is a used component, normal signs of wear such as scratches, discoloration, or light surface corrosion may be present. Refer to the product photos and information on Second Truck Parts for the best representation of the part you will receive.

doesn't open can, leaves aluminum shavings
could not cut through rim of can at all, it barely even grabbed on even after trying on multiple cans. Just spun almost in place and left small aluminum shavings and slivers from the can on the counter. the mechanism does not compress and bit into the can enough to get through, just enough to tear it up

Excellent Can Opener – Safe, Effortless, and Smartly Designed!
I’m so impressed with this electric can opener! From the moment I took it out of the box, it was incredibly easy to use—just one touch and it does all the work for you. What really sets it apart is how it opens cans with a smooth edge, so there's absolutely no worry about scratching yourself or dealing with sharp, jagged lids. That’s a huge relief, especially for someone like me who cooks often and has had accidents with traditional openers in the past. The design is compact and sleek, making it easy to store in a drawer, and it feels solid and well-made in the hand. It’s also surprisingly quiet while running. I’ve used it on all types of cans, and it works like a charm every time. Honestly, I didn’t expect to love a can opener this much, but it makes such a difference in the kitchen. If you're thinking about getting one, this is 100% worth it!

Effortless Can Opening – A Game Changer in the Kitchen!
I absolutely love this Automatic Electric Can Opener! It makes opening cans so much easier and completely hands-free. No more struggling with manual openers or sharp edges—this gadget does all the work for you with just the push of a button. The smooth edge cutting is a huge plus because it keeps my family safe from accidental cuts. It’s lightweight, easy to use, and works perfectly with just a couple of batteries. I especially appreciate it when I’m multitasking in the kitchen because it saves so much time and effort. Honestly, it’s a must-have tool for anyone who cooks regularly, and it would be a great gift for seniors or anyone with hand pain or arthritis. Highly recommend—it has truly made my kitchen life easier!
