Connected Diagnostics

Real-Time Engine Fault Code Alerts And Intuitive Diagnostics Guidance, Delivered Instantly.

Connected Diagnostics made its debut to the off-highway market at the Bauma Exhibition (April 11) in Munich. Connected Diagnostics is active in over 35,000 on-highway vehicles today, and soon will be available for off-highway equipment. Connected Diagnostics provides a lifeline for customers, direct to Cummins, when they need it most.

Through an active telematics connection, Cummins-powered equipment can now wirelessly connect the engine to Cummins for immediate diagnosis of an engine system fault alert, and have valuable information delivered to the customer within seconds. The Connected Diagnostics notification can be instantly delivered to anyone the customer specifies, including customer equipment management, company leadership and equipment operators, through an e-mail notification or the Connected Diagnostics mobile app.


In a clear, easy-to-understand format, Connected Diagnostics notifications are instantly sent to the customer within seconds of a fault code occurring. These notifications identify and prioritize the fault codes, and provide a clear recommendation of the action to take based on the primary engine system fault, outlining the most probable root cause, and identifying any impacts to performance. A link to the Cummins-certified service providers in the area makes finding support fast and easy. The priority level assigned to the fault clearly advises whether immediate action is needed or how long the equipment can continue working before the fault will impact operation of the equipment.

Showtime: Bauma 2016

bauma 2016 April 11-17, Munich

Bauma is held every three years, and with approximately 580,000 visitors, it is famous for being the largest trade show in the world. Bauma has 605,000 square meters of exhibition space packed with construction and mining equipment – anything worth knowing about the European construction and mining markets is on display here.

Bauma attracts a diverse audience, with visitors traveling from 200 countries to attend. Cummins has exhibited at Bauma for many years now, and each year, the show’s popularity has noticeably increased – 2016 attendance was up 9 percent from Bauma 2013, and with glowing reviews, who know what records Bauma can break in 2019?

Bauma is a key platform in the industry to launch new products and innovations. Cummins chairman and CEO Tom Linebarger took the opportunity to launch the new Stage V engine range to the world.

“Every three years, Bauma offers us the unique opportunity to meet with customers from around the world. As the largest trade show in our industry, it is a good opportunity to showcase new products and services.”

— John L. Garrison, CEO and President, Terex Corp.

“We make use of the attention Bauma attracts to present our innovations.

Stage 5 Vision

Cummins launched the new Stage V Engine lineup at Bauma in Munich. Bauma, held every three years, is the world’s largest industrial exhibition, and was the perfect platform to reveal a new generation of ultra-clean engines designed to meet European Union (EU) Stage V emissions regulations in 2019. With a proven portfolio of existing products already visible throughout the show, the announcement of an impressive new lineup was eagerly awaited by industry journalists, OEMs, competitors and enthusiasts.

Tom Linebarger, chairman and CEO, and Jim Fier, Vice President – Engineering, introduced the engines to an audience of over 200 people and coverage of the new engine lineup has been spread worldwide since the show.

The newly revealed F3.8, B4.5, B6.7 and L9 engines range from 100 hp to 430 hp (75-321 kW), and achieve a major increase in power and torque by removing the Exhaust Gas Recirculation (EGR) system and using Cummins Single Module aftertreatment technology. Linebarger commented at the new engine launch that “Cummins is raising the engine performance bar higher with our EGR-free approach for Stage V, and that leadership will continue to drive the equipment industry forward to meet the regulations in 2019 with simpler machine integration.”

Showtime: Bauma 2016

“The engines we unveiled today have been designed from the outset
to reduce Stage V cost of ownership to levels equivalent to those of engines meeting emissions regulations as far back as 10 years ago. This achievement is the result of product development inspired more than
ever by the needs of our customers rather than by just meeting emissions regulations, however stringent they may be,”

— Tom Linebarger, Chairman and CEO, Cummins Inc.

Compared with that of current Stage IV and Tier 4 Final engines, power output of the new 3.8-liter to 9-liter engines for Stage V is increased by over 10 percent on average, and peak torque is increased by almost 20 percent. The combined cost of fuel and urea consumption is reduced by 3 percent on average, depending on application. The X12 and X15 engines complete the Stage V lineup, taking output up to 675 hp (503 kW) for heavy-duty applications. The F3.8 is also available at a 74-hp (55 kW) rating, ideally suited for compact equipment requiring high levels of torque.

Bauma was a great success for Cummins, and the EGR-free engine technology for Stage V was successfully kept confidential so that the big reveal at Bauma triggered lots of interest and set a solid foundation for the new Cummins products of 2019.



Stage V - Technology That Transforms

Cummins Stage V Engine Lineup

These Next Generation Engines are designed for the Stage V European Union (EU) Emissions Legislation which will be introduced in 2019. The different engine names allow easy identification of the Stage V range. The engines will also be Tier 4 Final certified, allowing EU manufacturers to export their machines powered by these engines to North America.

Customer Spotlight: Apache

APACHE Sprayers powered up with Cummins QSB6.7 T4F engines earlier this year, with Cummins powering all four models in the 2016 Apache 30 Series self-propelled sprayer line. All models will boast greater horsepower in the new model year while consuming less fuel and providing a steadier ride than previous models.

According to Equipment Technologies, the upgrades to the Apache sprayers begin under the hood, where the Cummins 6.7-liter Tier 4 Final engines “generate higher horsepower while stretching fuel further than their 20-Series predecessors.”

“Cummins is always looking for ways to help our customers succeed… We are happy that our Tier 4 Final QSB6.7 is able to help Apache customers operate with more power and efficiency.”

— Bruce Farrar, Cummins Industrial Sales Manager

The 30-Series 6.7-liter-powered lineup consists of the AS730, rated at 173 hp (129 kW); the AS1030, rated at 225 hp (168 kW); the AS1230, rated at 260 hp (194 kW); and the AS1230 XP, rated at 300 hp (224 kW).

The QSB6.7 Tier 4 Final engine is one of the most popular and versatile engines ever built by Cummins. With features such as a High-Pressure Common-Rail (HPCR) fuel system, cooled Exhaust Gas Recirculation (EGR) and Diesel Oxidation Catalyst (DOC)/Selective Catalytic Reduction (SCR) ultra-low-emissions systems, it is no surprise that the Apache sprayers are seeing 5 percent to 20 percent better fuel efficiency than their 20-Series predecessors.

“Our 2016 models raise the bar for quality and value…We believe that growers will like what we’ve done, and will enjoy greater cost savings and profitability with these new machines.”

Cummins RAPIDSERVE™ Call Center has been around for more than 20 years. Since Cummins elected to require dealers to file warranty claims directly over RAPIDSERVE™ Web in October 2015, the RAPIDSERVE Call Center has taken a different approach on how it supports dealers. The RAPIDSERVE Call Center continues to support repair locations with catastrophic repairs. It also provides repair locations with technical support by helping when they have completed Cummins published troubleshooting and a failure was not found. If the repair issue cannot be resolved at the first level, the issue may be escalated to a technical support agent to help find a root cause. If necessary, Cummins will utilize its technical experts onsite to assist dealers as well.

Cummins has made several improvements to RAPIDSERVE Web to assist dealers in making the claims-filing experience easier. Improvements made over the last year include:

  • Expert Diagnostic System (EDS) auto-transfer of troubleshooting and access Standard Repair Times (SRTs) to RAPIDSERVE Web claims
  • Enabled claim filing for parts-only dealers on RAPIDSERVE Web to eliminate the need to call to file a claim
  • Improved RAPIDSERVE Web refile function
  • Dealer warranty training added to QuickServe© Online

Cummins RAPIDSERVE Call Center and RAPIDSERVE Web will continue to make improvements to the claim filing process and technical support so it is easier for dealers.

The Art of Remanufacturing

Cummins New and ReCon® Parts have spent decades being perfected by the art of remanufacturing. Cummins uses factory processes, advanced tools and quality systems to return remanufactured parts and engines to their original performance specifications, with the global warranty and service support to match. Bottom line: It is about giving customers a product that is as good as or better than new. Under the Cummins ReCon brand, remanufactured engines offer minimized downtime, a good-as-new warranty, technology upgrades and superior reliability.

Remanufacturing has significant environmental advantages – saving 85 percent of energy compared with manufacturing a brand-new product. While that is a number to be proud of, Cummins is striving to make it even better by offering ReCon products soon after it releases its new engine counterparts, and by applying advanced remanufacturing technology supported through enhanced processes.

Cummins has also recently instituted a variety of remanufacturing technologies that improve the workmanship of the end product by bringing more reusable components back to their original specifications – redefining the conventional process. One of these key advances enables material to be added back to critical engine parts using processes such as thermal sprays and laser deposition, meaning that old components are brought back to original performances, tolerances and specifications before going into the remanufactured engine. Recently, there has been a shift in demand to smaller, more compact engines, making it beneficial to add rather than remove material, to compensate for the wear that occurs in service.

For example, Cummins can use thermal sprays to repair and add material to the top of cylinder decks, avoiding the need for thicker head gaskets. Further examples are using laser deposition in turbocharger and cylinder heads to repair wear or corrosion, and utilizing plasma sprays to bring cylinders back to original spec size so that oversized pistons or sleeves are often no longer required.

For U.S. Environmental Protection Agency (EPA) Tier 4 Final and European Union (EU) Stage IV near-zero emissions regulations that took effect in 2014, Cummins has a technology solution with clear advantages for every type of equipment.

While other manufacturers outsource their emissions aftertreatment systems at Cummins, we manufacture our own. This total integration of the engine and the exhaust system allows us to optimize fuel economy above the 5 percent we’ve already achieved with Tier 4 Interim engines, while achieving near-zero emissions at the same time.

QSL9 engines are rated at 250 hp to 400 hp (186-298 kW) for Tier 4 Final. They have the same heat rejection as the Tier 4 Interim engines, so there is minimal, if any, impact on the cooling package. The QSL9 combines very high strength with a compact footprint, for one of the best power-to-weight ratios in its class.

This engine is used in every type of construction equipment – excavators, cranes, wheel loaders, compactors, air compressors and materials-handling equipment such as heavy forklifts and container-handling trucks. It is commonly found in agricultural tractors and sprayers, as well as chippers and feller bunchers in the logging market.

All of the performance upgrades from Tier 4 Interim have been incorporated into the Tier 4 Final engines, and we’re maximizing torque output, reaching 1200 lb-ft (1627 N•m) for the QSL9.


Sulfur Tolerance Kit

In January 2016, Cummins announced that its Sulfur Tolerance Kit, for Stage IIIB/IV engines from 37 kW to 503 kW, designed to allow export of emissions-compliant equipment into global regions without access to Ultra-Low-Sulfur Diesel (ULSD), was available.

Cummins Sulfur Tolerance Kit for Off-Highway Engines (49 hp to 675 hp) allows conversion of a Tier 4 or Stage IIIB/IV engine so it can run with excellent reliability and durability using high-sulfur diesel fuel (up to 5,000 ppm of sulfur). That is done through removal of aftertreatment components and modification the engine control system.

Tier 4 and Stage IIIB/IV engines are required to meet U.S. Environmental Protection Agency (EPA) and European Union (EU) standards, and are designed to operate only on ULSD, which has less than 15 parts per million (PPM) of sulfur. ULSD is not available in every region of the world, and operating an engine on highsulfur diesel fuel will cause significant performance issues.

The Sulfur Tolerance Kit was displayed at Bauma 2016, and attracted a lot of attention from visitors to the booth. A full product brochure for the Cummins Sulfur Tolerance kit can be found here

Download The Sulfur Tolerance Kit Brochure.

"The release of Cummins Sulfur Tolerance Kit broadens resale opportunity for customers, allowing them to sell used emissions-compliant equipment into non-emissionized countries... . The kits increase the flexibility of Cummins products, making them capable of operating globally, and ensuring that subsequent owners experience the same reliability and durability that customers expect from Cummins."

– Hugh Foden, Cummins Executive Director – Off-Highway Business


Sulfur Tolerance Kit

Meeting emissions regulations in Europe and North America requires the use of Ultra-Low-Sulfur Diesel ULSD fuels, which contain fewer than 15 parts per million (ppm) of sulfur, to reduce particulate matter (PM), soot and sulfur dioxide (SO2). Cummins Sulfur Tolerance Kit allows an engine to be operated on fuels containing far more sulfur than ULSD – up to 5,000 ppm – through removal of aftertreatment components and modification of the engine control system, enabling a second life for the engine outside of regulated regions.

Currently available for the popular Stage IIIB/Tier 4 Interim QSB6.7, QSL9 and QSX15 engines and then extending across the entire 37 kW-to-503 kW (49-675 hp) product lineup during 2016, the Sulfur Tolerance Kit includes new engine calibration and hardware, depending on engine model, and is solely intended for used engines that are exported into non-regulated regions.

For further information on Sulfur Tolerance, contact Cummins Care Europe ( Information on the purchase and installation of the Sulfur Tolerance Kit is available from Cummins distributors or online at
