New Cummins Crate Engines to Provide Enthusiasts with Clean, Powerful Alternative

Anything Scout, an Ames, Iowa (U.S.A.) company, has seen significant fuel efficiency gains using the R2.8 Turbo Diesel to repower a classic Scout.

CUMMINS NEW CRATE ENGINE PROGRAM, CUMMINS REPOWER™, WILL NOT ONLY GIVE TRUCK ENTHUSIASTS A POWERFUL ALTERNATIVE FOR THEIR OLDER ICONIC OR SENTIMENTAL PROJECTS, BUT A CLEANER, MORE FUEL EFFICIENT OPTION, TOO.

"Without question, the environment is very important to Cummins,” said Jeff Caldwell, Executive Director of Cummins’ Global Pickup/Van Business. “We’re excited to provide enthusiasts with a cleaner and much more fuel-efficient engine than their original, or even a junkyard Cummins swap.

“Cummins Repower will allow them to enjoy their iconic vehicles that much more,” he said. “There are certain vehicles people just won’t discard. We want to help make those vehicles as clean, reliable, economical and enjoyable as possible for many years to come.”

The crate program was born after customer surveys identified significant demand for Cummins engines in the consumer aftermarket. Typically, the company’s engines are sold to truck manufacturers or truck fleets, often in large numbers. Cummins Repower is called a “crate” engine program because customers will be able to purchase engines in small volumes – as few as one – and they will arrive in crates.

The first Cummins Repower offering will be the R2.8 Turbo Diesel, including an alternator, power steering pump, cam-driven vacuum pump, remote mounted oil filter and a universal wiring harness to ease the installation process for many different vehicle models.

Initial testing focused on an R2.8 installed into an otherwise stock 2000 Jeep® Wrangler® in place of the Jeep’s original 4.0L gasoline 6-cylinder engine. The vehicle not only gained higher peak torque with the R2.8, but the amount of accessible peak torque across the RPM band also increased.

In addition to the performance gains, preliminary testing indicates that the R2.8 more than doubled the fuel economy of the Jeep while meeting the Transitional Low-Emission Vehicle (TLEV) LDT2 emissions standards for that particular gasoline engine vintage.

With mileage numbers of 30.8 mpg on the highway and 25.8 mpg in the city as compared to a stock 1997 Jeep Wrangler TJ with a 4.0L’s rating of 16-18 mpg highway, 13-15 city, the Cummins-powered Jeep had a carbon dioxide (CO2) emissions improvement of over 25 percent.

The first end customer for the program worked with Anything Scout of Ames, Iowa (U.S.A.) to rebuild a 1967 Scout 800 on a modified brand new Jeep Wrangler chassis with all modern components. The company, which regularly uses V8 crate engines for their builds, was very happy with the performance and fuel economy of the R2.8 Turbo Diesel during a 3,500 mile “shake-down” run driving to the West Coast and back.

“We have never seen better than 18 mpg with our fuel injected V8 swaps and we were thrilled to be getting 25 miles per gallon on the first long drive from Iowa to Arizona,” said Sean Barber, owner of Anything Scout.

“We have customers who bring us their grandfather’s truck and ask us to restore it back to original looking condition, but they want them to also be usable so that’s when we transplant modern running gear under the classic steel,” he said. “These vehicles have large tires and aren’t aerodynamic – so to be getting 25 miles per gallon with no smoke or smell is amazing.”

Certification work is underway using the California Air Resources Board’s (CARB) Executive Order process to ensure that every Cummins Repower engine sold has clear guidelines as to the specific vehicle classification and vintage for which it is qualified to be installed.

Cummins is also working closely with the Specialty Equipment Market Association® (SEMA) and other key SEMA members to prepare the market for genuine Cummins Repowers. The SEMA Garage™ provides members the necessary access to the Cummins Repower products, enabling them to bring their own ancillary products to market, with the result for the enthusiast being a plug-and-play option for every step of the installation.

Full production of the R2.8 is anticipated in the fall of 2017. Future engine family introductions into the Repower product lineup will be announced at later dates.

There’s a bit of nostalgia in the program for Cummins, which really hasn’t sold engines in quite this way since the company’s namesake and founder Clessie Cummins was in charge.

“Clessie Cummins repowered automobiles, race cars, buses and trucks, demonstrating the benefits of the diesel engine over their original power plants.” Caldwell said. “Nearly 100 years later, we are proud to be continuing the legacy of our namesake by enabling passionate enthusiasts to repower their iconic vehicles for the same reason Cummins repowered his own.”

Cummins Repower Blog: Overland Expo West

R2.8 Powered Vehicle

The following post was authored by Allison Janowski, Marketing Communications Specialist for Cummins Repower, who recently attended the Cummins booth at Overland Expo West in Flagstaff, Arizona.

This week, the Cummins Repower team headed to Overland Expo West 2018. We packed up our vehicles and started our engines and made the 1,700 mile journey from Columbus, Indiana to Flagstaff, Arizona. Our Cummins R2.8 Turbo Diesel repowered Jeep Wrangler TJ and Land Rover Discovery 1 made the trip with ease and arrived at the expo showgrounds Thursday afternoon. We were excited with the amount of Cummins powered Overlanding rigs that greeted us when we entered the expo for show set up. We were eager to set up our booth for the 3-day event, and our technical team was ready to answer any repower questions.

Our booth featured the Cummins R2.8 engine, kit contents and crate, as well as our TJ and Discovery, but the stars of the show were the customer built repowered vehicles scattered throughout the expo. We were excited to see that five other Cummins R2.8 builds made it to the show. After setting up our booth we walked the show to meet these builders and see their hard work.

The Clean Cruiser Project

First stop was the Clean Cruiser Project booth and their original mustard yellow colored BJ42 Toyota Land Cruiser. Their work in progress build caught your eye as you walked down the gravel path, but they had an even cooler story to tell. These guys are taking this BJ42 and another restored 1979 FJ40 to Columbia in 2019. They plan to make some amazing memories, but also reduce their carbon footprint to zero by planting 200 trees during their adventure.

Proffitt’s Resurrection Land Cruisers

We then made our way through the crowd surrounding Proffitt’s Resurrection Land Cruisers booth to see their 79 Toyota Land Cruiser. As one of our first beta builders, we love seeing this shiny SEMA vehicle that can tackle any trail, too. The Land Cruiser was ready to take on the Overlanding experience with a newly added rooftop tent and a bed full of all the necessities. Proffitt’s specializes in premier Toyota Land Cruiser restorations, and they all turn heads.

DELTA Vehicle Systems

Across the way from our booth was DELTA Vehicle Systems. DELTA Vehicle Systems brought their Toyota Land Cruiser FJ80. They were excited to debut their complete frame off 80 series R2.8 build with a new paint job and packed full of their products. They are building custom adaptor plates and completed, ready to bolt on vehicles accessories.

Overland Cruisers

Our friends from Overland Cruisers featured a built R2.8 Toyota Land Cruiser FJ60 in their booth. This 60s series looked like it was yearning to hit the trails and start its maiden voyage as a newly repowered diesel Land Cruiser. Overland Cruisers is a full service Toyota Land Cruiser and Toyota 4WD specialty shop, specializing in full restorations, engine conversions, repairs and so much more. They truly do have a passion for ‘cruisers.

Cummins Repower Blog: Overland Expo West Road Trip

R2.8 Outside of Cummins Engine Plant

The following post was authored by Brittany Borella, the Technical Leader for the Cummins Repower Program, who recently went on a multi-day road trip in the R2.8-powered Land Rover Discovery 1. 

My road trip started on a sunny day outside Plant 1 in Columbus, Indiana - the location of Cummins’ Headquarters.

I packed up all my stuff for my first camping adventure since I was a kid, and headed west. At 5640 lbs fully loaded and with the aerodynamics of a small tool shed, the R2.8 powered Landrover Discovery 1 was easily able to cruise at 70 mph across the country, and get 17 mpg while doing it.  

R2.8

The first stop was Overland Expo West in Flagstaff, AZ - The Disco and I were to work the Cummins booth. Overland Expo is always a great show and we were able to speak to a lot of existing or potentially new Cummins Repower R2.8 owners, but by Sunday, I was ready to hit the road. 

R2.8


I headed north out of Flagstaff to cross the Utah state line before nightfall, and camped for the night in the Coral Pink Sand Dunes State Park. 

R2.8

If you’ve never been to the sand dunes, I recommend a visit longer than mine – and be sure to bring your 4-wheeler or side-by-side. 
 

R2.8


My stay at the Dunes was short, and I was off to Zion National Park for two days of hiking and camping. I drove through the East Entrance in order to catch a glimpse of the “entire” park and spent the rest of the day down in the Canyon. While the Canyon is the busiest section of the park, it still provides some amazing views, and you can see why Zion is the 3rd most visited National Park in the Country (beat out only by the Great Smokey Mountains and Grand Canyon).

R2.8

The next day I decided to avoid the crowds and spend some time on the Kolob Terrace, which is accessed via a 20-mile scenic drive up into the higher elevations of the park. My hike led me to an amazing 360° vista, where you can start seeing the vastness of the park below you. Notes for next time – stay at the Lava Point Camp ground (another hidden gem at the top of Kolob Terrace), and plan on hiking (wading?) the Narrows.

R2.8

My trip continued across the deserts of Nevada, where I encountered a group of Defenders also on a trip post-Expo. We chatted while stopped at the Alien Diner on the Extraterrestrial Highway, but then parted ways as I continued into the mountains and they set off to explore the desert floor. 

R2.8

Camp was set up overlooking a mountain lake at 8000 ft elevation, which made for a chilly nights sleep but some amazing views in the morning. Breakfast and coffee, and it was time to hit the road.

R2.8

The camping spot at June Lake sat just outside the east entrance of Yosemite National Park, so that’s where I headed. Climbing the grades into the park again allowed access to some of the lesser trafficked hiking trails.

R2.8


I took a break from driving to hike up to Dog Lake and then the top of Lambert Dome. It was a fairly strenuous hike when combining the elevation with the steep grade, but the views were well worth the sweat and sunburn (the sun is much stronger at 10,000 ft!)

R2.8

After a small snafu with a snap ring in the shifter required a complete disassembly of the center console (which seems to be something I have to do on every cross country trip, regardless of vehicle or issue) the mountains were behind me and I was headed towards the coast. I stopped outside of San Francisco to visit my sister where she took me on a rainy hike through the redwoods. Soaked feet and tired bodies brought us back to the main house for a warm fire and a home cooked meal.

The clouds broke the day of my departure, which allowed for a pleasant drive down the coast to meet up with Fred. I distracted him from Ultimate Adventure prep long enough to put the Landrover’s center console back together and take it (and the doggos) to Pismo beach for Memorial Day.

R2.8R2.8

As I sit at the airport awaiting my flight back home to Indiana, I’m happy to be out of the driver’s seat but grateful for all the adventures I was able to go on over the last 2 weeks. I accumulated over 3000 miles on the odometer, countless hours of validation on updates to the R2.8 calibration (look for an announcement later this summer), and memories to last a lifetime. This trip makes me even more excited looking ahead to Cummins Cruise 2018!

Fuel Economy Summary:
Indiana to Flagstaff : 17 mpg
Flagstaff to Zion: 19.6 mpg
Zion to Yosemite: 18.7 mpg
Yosemite to Pismo Beach: 20 mpg

Top RV Maintenance Tips from Cummins for Travel Season

rv driving on open desert road

Spring’s longer daylight hours and warmer weather call RV owners out to the open road. But before you succumb to the urge to start up the diesel engine and roll out on the highway, proper spring RV maintenance will ensure a smoother ride all season long.

“Walk around the coach just like you would your house in the spring,” Chris Crowel, Cummins RV Market Leader, says. “The best way to see if your home needs maintenance is to get out and look at it. Do the same type of inspection of your coach to see how it faired through the winter weather.”

Here are 5 tips to prepare your RV for travel season:

1. Get out and inspect everything.

Look for any broken seals or cracks on the exterior of the coach that need to be repaired. Lift the engine cover, open up the basement and inspect every compartment. Keep an eye out for:

  • Insect and bug nests that may disrupt air flow
  • Plugged crankcase breather tube from ice or debris
  • Cracks or bent blades on cooling fan
  • Check the condition of your belts and hoses

2. Top off coolant.

At a cool temperature, top off with coolant that meets Cummins Engineering Standard: CES14603 for optimal performance. Note: never open a hot coolant reservoir – since the main role of coolant is to absorb heat from the engine, it can get very hot.  Periodically check coolant levels and concentration to ensure your RV engine is appropriately protected by the coolant – preventing corrosion, aeration, scaling, and other issues that can cause harm to your engine.  Consult your Owner’s Manual for additional details.

3 - Proper oil level on dipstick.

If you did not change your oil before the winter, we recommend draining and changing your oil fluid before you hit the road or a long trip. For a Cummins engine, we recommend a CJ-4 (CES20081) oil such as Valvoline Premium Blue.  Oil is used to lubricate, cool components,  cleans the system, inhibit corrosion, and improve sealing.  When in storage, oil can pick up moisture from condensation and additive packages in the oil can drop out.  Both miles and time cause oil to deteriorate over time.

4 - Drain water out of the fuel water separator.

Most coaches have a Water in Fuel (WIF) sensor and lamp indicator to detect the presence of water in the fuel. Water can result in inadequate lubrication of fuel system components like pumps and injectors which could result in expensive repairs.  With the engine off, drain the fuel-water separator to ensure the diesel fuel is free of water.

5 - Follow engine maintenance recommendations.

Ideally, diesel engine maintenance and oil changes occurs prior to long-term winter storage. However, if that did not take place in the fall, spring marks the time to ensure proper engine maintenance. Even if your coach has not traveled hit the mileage noted in the operating manual, we still recommend the following maintenance intervals for engine:

  • Engines 450 HP and below (ISB6.7 and ISL9) - once per year
  • Engines 500 HP and above (ISX12 and ISX15) - every 6 months.

Cummins Repower Blog: Easter Jeep Safari Moab Day 2

Day two out in Moab for Easter Jeep Safari led us to Kane’s Creek trail with Ian Johnson from Digital Lug. Ian graciously let our misfit band of R2.8 powered vehicles crash his planned ride and even let us lead the way! On the ride we had Fred Williams (of Dirt Every Day) in Tubesock, Christian Hazel and Verne Simons (of 4-Wheel and Off-Road Magazine) in the UACJ6, Dirthead Dave Chappelle in Diesel Power Products Stretched off-road 8-speed JK, and Bruiser Conversion’s 4-door, 4-wheel steering off-road JK.  The Cummins Black TJ and Landrover Discovery picked up the rear of the group.

Kane’s Creek is a scenic trail that winds along the riverbed, riddled with river crossings and the occasional rock obstacle. The R2.8 powered vehicles drove flawlessly through anything put in front of them, from water to sand to rock. A ride like this really lets us see how our customers use their vehicles and why they made the build choices that they did. Axis’s seamless integration of the ZF 8-speed into the Diesel Power Products vehicle meant that the transmission could always choose an optimal gear to efficiently and effectively use the power and torque of the R2.8. Bruiser’s JK was equally well integrated, turning diesel power, fuel economy, and reliability into a fun and capable rig for any trail.

The end of the trail is a technical climb up out of the Canyon with a series of shear rock faces and complicated lines. The UACJ6 and JK’s of the group with bigger tires had no problem using that turbo diesel torque to crawl up. Even the Cummins Jeep TJ made it up without incident, slowly climbing its way to the top.

The Landrover once again proved that this is Easter JEEP Safari, and clipped a rock on one of the last obstacles at the top of the canyon climb. This allowed us to implement our second bush fix of the trip – cover it with stickers.

The night ended at the Daystar party up at Sunset Grill, which I’m sure has a million dollar view as the sun goes down over the western horizon. Unfortunately we were there after dark, but it still awarded us a beautiful view of the lights down in the city. Day 2 was in the books and we’re gearing up for Day 3!
