Issue 1 September, 2015

Welcome to the first Issue of CTB e-magazine.

As you can see from the topics listed, our new e-magazine gives you plenty to read about, as it covers everything from Tier 4 technology to latest updates to QuickServe® Online. Plus, you will find features about Cummins-powered equipment, product profiles, parts and service updates. I hope this all comes together to provide you with a clearer picture of how we can help you support your customers.

You may already be familiar with the Cummins ToolBox name, associated with our Forward to Final web site introduced for dealer use about a year ago. We have linked CTB e-magazine and the web site because they serve the same purpose — to help you sell, learn about and support our Tier 4 Final and Interim products.

While we recognize that having the best technology in the industry is key, equally important is having the best-supported dealer network. That’s our goal. And we are vigorously undertaking initiatives to achieve that. Dependability is Cummins single most important attribute, and we know that our dealers play a major role in sustaining that brand promise to our customers.

So, I will leave you to browse through CTB. If there is anything you need to know in more depth not covered in this issue, talk to your local Cummins distributor, who will be pleased to answer your questions. Feel free to e-mail me with any suggestions about CTB at


Tried And Tested: Tier 4 Final

+150,000 Hours.

Cummins Tier 4 Final field-test program accumulated over 150,000 hours to ensure that our engines were fully proven before the start of production. Initiated in 2012, the program included nearly 70 machines, encompassing the toughest duty cycles. The equipment was operated on sites selected specifically to cover the most challenging conditions, from the high heat of Texas to the extreme cold of a Canadian winter.

The field-test program went beyond typical wheel-loader and excavator endurance test cycles to cover a wide variety of specialized equipment that included a snow groomer at very high altitude in the Alps, a container handler working high hours on the port side and a rock drill working on a mine site in very dusty, abrasive conditions.

Up To 10% Lower Fuel Use.

Overall results from the field-test program indicate that Cummins Tier 4 Final technology lowered fuel consumption by up to 10 percent compared with that of an equivalent Tier 3 machine, dependent on duty cycle and application.

Cummins field-test work has paid close attention to minimizing Diesel Exhaust Fluid (DEF) consumption. Results showed that DEF is typically dosed at just 3 percent to 4 percent of diesel by volume.

How It Works: SCR

NOx Reduction Technology.

Selective Catalytic Reduction (SCR) aftertreatment has been adopted throughout the engine industry to meet Tier 4 Final emissions regulations above 74 hp (55 kW). So, how does SCR work to reduce emissions?

The first thing to make clear is Cummins takes a balanced approach to nitrogen oxides (NOx) reduction by using cooled Exhaust Gas Recirculation (EGR) on the engine to work in combination with the SCR aftertreatment. In this way, both the engine and SCR function more easily and allow fuel consumption to be better optimized. Adding SCR for Tier 4 Final also enables the amount of EGR flow to be reduced compared to Tier 4 Interim, putting the engine in a wider combustion 'sweet spot'.

Unique Selling Proposition

Cummins SCR system uses only 3 percent to 4 percent of DEF to fuel consumed, depending on duty-cycle.

How It Works: SCR

NOx Reduction Technology.

While any discussion about SCR can quickly turn into a chemistry lesson, in terms of real-world operation the system is transparent to the operator, requiring only refilling of the DEF tank when required to achieve near-zero NOx emissions.

Cummins SCR is a robust design strengthened for the highest vibration and shock loadings experienced by off-highway equipment — and will last the life of the engine without any scheduled maintenance. Latest insulation techniques maintain optimum temperature throughout the system.

Going Beyond 500 Hours.

Going Beyond 500 Hours.

All Cummins Tier 4 engines come with a standard 500-hour oil and filter change interval. The interval is based on the average duty cycle and anticipated oil contamination rates for engines using the recommended oil and filter types.

There is a direct relationship between a more severe duty cycle or very dusty conditions with increased oil deterioration. A harder-working engine consuming more fuel introduces fine contaminants into the oil, and correlates to more engine wear. Machines spending a higher percentage of time at idle or with lower load factors will maintain the oil grade for longer.

Contamination can be identified by undertaking regular oil analysis, and the results will indicate if the engine needs to maintain the standard 500-hour change or may be able to safely extend the change interval to as many as 1,000 hours and beyond.

The opportunity to extend oil change intervals will be of interest to many operators, as even the savings achieved by a 600-hour interval will more than pay for the oil-analysis monitoring.

Extended oil-change intervals:

Regular oil analysis determines whether oil quality remains stable enough
(depending on duty cycle) for extended intervals.

Regardless of change interval...

  1. Check the oil level daily.
  2. Use the Cummins-recommended oil type.
  3. Use high-quality oil, such as Valvoline®
  4. Use high-quality oil filters, such as Fleetguard,® and
    change as needed, to reduce oil contamination.

Forward To Final.

Our 6.7-liter is the most popular and widely used engine built by Cummins. Over many years, it has established itself as the "standard of the industry" that all other midrange competitive engines aspire to match. None ever has, as evidenced by the fact that the QSB6.7 is used by more OEMs, in more applications and in more countries than any other engine in its power category. And does any other engine in its class work harder, for longer? No. It's a rock-solid performer.

Evolution: Almost no engine change from Interim to Final other than enhanced electronics and a lower EGR loading. The typical fuel saving at Interim improves by an additional 3 percent to 5 percent.

The Interim DPF evolves to a DOC-SCR, using DEF at typically 3 percent to 4 percent of fuel consumed.


Tier 4 Engine Tear-Down

Durability Proves Equal To Tier 3.

Cummins recently announced the results of a Tier 4 Interim engine tear-down inspection, undertaken to assess in-service durability and achievable life-to-overhaul compared with the Tier 3 version of the engine. The disassembly and in-depth examination of a QSL9 engine at close to 10,000 operating hours revealed the major components, fuel system, turbocharger and block to be in near-perfect condition after three years of operation in a heavy lift-and-carry application.

"Cummins design philosophy is to utilize only proven technologies and components that we know will meet the in-service reliability and long-term durability demanded for the toughest equipment applications, and the advantage of taking that approach is reflected in the impressive results of this QSL9 Tier 4 tear-down inspection," said Hugh Foden, Executive Director – Cummins Off-Highway Business.

The Cummins engineers who conducted the tear-down inspection concluded that the Tier 4 Interim-compliant QSL9 was capable of achieving up to 20,000 hours of operation before an engine overhaul may have been expected — equal to that of a Tier 3 version of the engine working on a similar duty cycle. The evaluation confirms that Tier 4 engines with low-emissions technology provide the same inherent durability as demonstrated by their simpler Tier 3 engine predecessors.

Upon inspection, the QSL9 engine was in such good condition after nearly 10,000 hours of operation that it could have been reassembled and returned to service without any component change or maintenance intervention.

Tier 4 Tear-Down

20,000 Hour
Life-to-Overhaul Achievable

Rated at 350 hp (261 kW), the QSL9 engine selected for the durability assessment had required only standard servicing during the three years of operation, with no repair work or unscheduled maintenance ever needed.


Tier 4 Engine Tear-Down

230 Measures.

The durability evaluation procedure for the QSL9 was extremely rigorous, with over 230 specific measurements and values taken from the stripped-out components.

Before the tear-down inspection, the QSL9 was tested on a range of performance factors such as power delivery, fuel consumption, emissions and torque, to prove that the engine remained within acceptable tolerance levels of the original production specification.

Like their Tier 3 predecessors, Cummins Tier 4 Final engines are designed with rebuild potential, to enable an easier and lower-cost overhaul. A further benefit is that the Tier 4 engines do not require any specific midlife maintenance intervention. Cummins exhaust aftertreatment systems are equally robust, protected against the most severe shock loads and designed to achieve the same life as the engine.

QSL9 Cummins 9-liter engine offers an ideal platform for a durability comparison, as the base engine has remained almost identical during the transition from Tier 3 (Stage IIIA) to Tier 4 Interim (Stage IIIB) and to the Tier 4 Final (Stage IV) version. The engine is utilized in demanding applications varying from excavators and wheel loaders to crawler cranes, snow groomers and reach stackers.

20,000 Hour
Life-to-Overhaul Achievable

After nearly 10,000 hours of operation, the QSL9 engine could have been reassembled and returned to service without any component change or maintenance intervention.

Pioneering the Diesel Shovel.

The 104 Power Shovel, built by Northwest Engineering, was one of the earliest earth-moving machines to offer a lower-cost diesel alternative to steam power, using the 4-cylinder 9.3-liter Cummins Model F with 50 hp which was installed in 1925.

It was Cummins first engine installation into mobile off-highway equipment, following on from marine and stationary power application after the foundation of the company in 1919. The tough working conditions of the cable shovel led Cummins to make rapid progress in developing more robust engine designs.

Northwest Engineering later became the founder company of Terex,® which remains a customer of Cummins today, retaining a link stretching back 90 years.
