“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.”

Schedule Expert RV Maintenance

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.

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.

Rebuild masterstroke pays off for miners

A masterstroke by Cummins engineers in Australia and the US has resulted in major cost reduction and environmental benefits for mining companies electing to rebuild their QSK60 engines under a special upgrade program.

The engineers focused on rebuild possibilities for the early generation QSK60, and how it could be upgraded to the latest diesel technology at overhaul time with no major change to the base 60-litre V16 design – a feat that eluded other engine manufacturers.

The key technology upgrade is to fuel injection, with the early unit injection system (HPI) replaced with the high-pressure modular common rail system (MCRS) that is now featured on all of Cummins’ latest generation high horsepower engines.

The 300th upgraded engine, rated at 2700 hp, recently rolled off the production line at the Cummins Master Rebuild Centre in Brisbane, highlighting yet another successful step in the evolution of the QSK60 and why it is the foremost high-horsepower diesel engine globally in mobile mining equipment.

“Reduced fuel consumption and longer life-to-overhaul are keys to lower total cost of ownership, and they were the initial aims behind the engineering of the upgrade program for the QSK60,” says Greg Field, mining business development manager for Cummins Asia Pacific.

“Innovation is at the core of Cummins’ long history, and it has certainly played its part in the QSK60 rebuild options we can offer our mining customers.”

The bottom line is impressive: Diesel particulate emissions are slashed by up to 63% through in-cylinder combustion technology with no aftertreatment. There’s also a plus for maintenance with less soot loading in the oil.

Fuel savings up to 5% are consistently reported in the field for significant greenhouse gas emissions reduction, while life-to-overhaul is extended by 10%, translating to fuel consumption of more than 4.0 million liters before rebuild is required.

Apart from the fuel system upgrade to MCRS, the QSK60 with single-stage turbocharging also features other Cummins innovations in combustion technology that were engineered for Tier 4 Final and Stage V emissions compliance, the most stringent off-highway emission standards in the world.

The rebuild upgrade package can be applied to the two variants of the QSK60 – one with single-stage turbocharging (known as ‘Advantage’) which can be rated from 1785 to 2700 hp, the other with two-stage turbocharging which can be rated at 2700, 2850 or 3000 hp.

The 300th upgraded QSK60 went to Boggabri Coal in the NSW Gunnedah Basin for installation in a Komatsu 930E haul truck. The engine has proved its worth in both coal and iron ore mining in Australia.

Hurricane Sally no match for Florida couple and their home standby generator

Three months. That’s how little time Macy and Sherry Summers had between the installation of their new Cummins QuietConnect™ home standby generator and its first major test: the arrival of Hurricane Sally.

The Category-2 hurricane stalled over the Pensacola, Fla. area for nearly 12 hours in September 2020, bringing 110-mph winds, torrential rain and major power outages. While many of their neighbors worried about their home flooding during the storm, the Summers were secure, knowing their Cummins generator would help pull them through.

“I was very concerned that if too much water got near the house, it could come in,” said Macy. “Without power, we couldn’t run our pumps, we couldn’t take the water away from our pool. That was the big fear for me.”

The new Cummins generator came through big time, powering their home and three sump pumps during the storm and running nearly 90 hours with one break for an oil change before power was restored.

Its performance was no surprise for Macy, a former Lockheed Martin engineer. Upon moving permanently into the home in 2019, he used his research acumen to find the best way to power their home through a storm. After 18 months, he decided on a Cummins QuietConnect Home Standby Generator because of the brand reputation, build quality and support.

“The brand was really important to us. We wanted to have a good support system from a large company we knew would be there if we needed it. It turns out that Cummins was the right one for us,” said Macy.

“I would certainly recommend Cummins over the brands that most people have heard of. Cummins is a stronger solution for somebody who wants that reliability.”

For the installation, the Summers contracted with Emergency Standby Power, their local Cummins dealer in nearby Fort Walton Beach, which also services and maintains the generator for them.

Said Raul Perez who oversees generator installations for Emergency Standby Power, “We try to partner with a product we know is going to be reliable that we’re comfortable servicing, that we’re comfortable installing and that we’re comfortable standing behind. That means a lot. We do like working with Cummins, because when we call and we need support, they’re always there.”

According to Sherry, the QuietConnect generator lives up to its name. “It’s amazing that when we hear it come on, we’ll always say, ‘Oh, there’s the generator. The power must be off.’ We just keep going about whatever we’re doing,” she said. 

After the hurricane, the Summers have complete confidence in their Cummins generator. Sherry says she no longer worries about food spoiling, keeping the house cool and keeping the pool pumps running. 

Macy adds, “If a hurricane comes, my peace of mind really is around these systems we’ve put in to protect our home. They’ll now have constant power, enabled by the generator.”
