Need to Replace Your RE541179 John Deere DPF?

The Roadwarrior catalogue includes aftermarket equivalents to 4 John Deere construction DPFs, complete with the clamps and gaskets necessary for a quick and easy installation. The Roadwarrior part D2066-SA is an easy-install replacement for your RE541179 or RE541834 John Deere DPF. Our DPF D2066-SA underwent rigorous testing before being released to ensure that it met OEM performance standards and was compatible with John Deere engines. To protect your investment, we also offer a hassle-free warranty on all our parts!



Why Choose a Roadwarrior Construction DPF?

Roadwarrior has the largest aftermarket catalogue in the aftertreatment industry, and we’re known for the quality of our parts. We’re also the only aftermarket company to make DPFs for construction machinery, which we stock in our Pennsylvania warehouse. Construction DPFs like D2066-SA combine a high-efficiency metal substrate and a Metalcor catalytic coating to achieve exceptionally high levels of emissions control and energy efficiency. Along with industry-leading catalytic research, access to Metalcor is one of the benefits of our ties to DCL International.



What Kind of Construction Equipment Requires Emissions Control? (Tier 4)

Due to high power demands, the majority of construction machinery runs on diesel. According to the Diesel Technology Forum, construction accounts for as much as 55% of U.S. off-road fuel use! To mitigate the environmental impact, the EPA brought in mandatory Tier 4 standards for all new off-highway diesel engines and heavy equipment sold from 2014. The inclusion of emissions control devices like DPFs in all new construction equipment has the added benefit of boosting fuel efficiency and preventing construction workers inhaling toxic fumes on-site.



What Should You Know About John Deere DPFs?The Roadwarrior part D2066-SA is an direct-fit substitute for your RE541179 or RE541834 John Deere DPF

John Deere is a well-respected engine and machinery manufacturer, specializing in construction, forestry, and agriculture. Their construction offering includes dozers, excavators, articulated dump trucks, crawler loaders, tractor loaders, wheel loaders, and more! John Deere began phasing in DPFs like RE541179 and RE541834 in 2011. By the time Tier 4 standards came into play, their machinery was fully compliant! They’ve since upgraded their systems multiple times in line with changing emissions regulations.


John Deere construction DPFs are tough and reliable, but regular exposure to sooty exhaust means they deteriorate faster than the equipment they’re used in. This is where Roadwarrior comes in! Our D2066-SA is an exact-fit replacement for John Deere construction DPFs RE541179 and RE541834. A Roadwarrior DPF lets you hit your quotas and crush your deadlines without the fear of aftertreatment failure! You can order through your local distributor, on our website or by calling our sales team on 1-877-897-9759.




What is a Construction DPF?

The exhaust from diesel-powered construction equipment includes soot and particulate matter (PM). Instead of releasing this toxic matter into the air on construction sites, the exhaust is filtered and cleaned by aftertreatment filters like DPFs. However, soot accumulates in the filter over time, and it has to regenerate to avoid becoming blocked.


On-highway machinery like semitrucks drive fast enough for long enough stretches to use passive regeneration (regens), burning through the soot with the heat of the exhaust. If this isn’t enough, the truck injects a small amount of fuel into the pre-DPF exhaust to raise the temperature more—this is an active regen. Most off-highway construction machinery rarely gets hot enough for passive regens and relies on active regens. 



What Causes RE541179 John Deere Construction DPFs to Fail?

John Deere DPFs are durable, but usually need to be replaced during the life of the machine. After 3,000-4,000 hours in typical construction machinery, and 250,000–500,000 miles in semitrucks, your John Deere DPF will become too clogged with soot to regenerate. At this point you’ll need to remove and clean it. Although this may take several days, it will significantly extend the life of your DPF and engine!


If you keep operating with a clogged DPF beyond this point, the exhaust won’t be able to pass through, building pressure. If this backpressure cracks the DPF, you’ll need to replace it. A John Deere DPF can also be damaged by oil and coolant leaks, and upstream engine issues. If this happens, your machine will trigger a DTC to let you know! If your RE541179 or RE541834 DPF fails and you need a quicker fix, why not consider Roadwarrior’s replacement D2066-SA?

Better Coating, Better Performance.

Roadwarrior is the only manufacturer to use Metalcor® catalyst technology across its entire range of Diesel Oxidation Catalysts (DOCs) and Selective Catalytic Reduction catalysts (SCRs). Metalcor® catalysts feature high activity catalyst coatings fused to thinner, stronger, catalyst substrates to guarantee maximum performance under the harshest conditions.

Metalcor® catalyst coatings are designed and produced in our own labs. We then inspect each unit to ensure you get more fuel efficiency, lower consumption of DEF, and long term performance from your heavy duty engine!


Roadwarrior Has You Covered!

All Roadwarrior emissions parts carry a full value 12 month warranty.

LightningVolt lithium batteries carry a full value 30 month warranty.

To make the process hassle-free, our parts have a metal nameplate with the serial number, so even after 500,000 miles of service, it’s still easy to identify. This avoids the common problem of serial numbers printed on stickers that burn off after the first start-up, making them impossible to return. Our failsafe system allows us to work in your interests, honouring claims for on-road and off-road replacements, and giving you peace of mind.

And since Roadwarrior parts are designed to meet or exceed OEM specifications, you can rest easy knowing our direct fit parts will take the problems out of your aftertreatment without interfering with your OEM warranty.
