Leading the Way in the Wind Industry

Making The Wind Industry Profitable

Nearly 58,000 wind turbines dot the American landscape. Nearly 50 percent of those now use AMSOIL synthetic lubricants in their gearboxes. Here´s the story of how we shook up the wind industry – and how it benefits you.

We dove into the wind market more than a decade ago for the same reasons we enter most markets: to solve a problem. At the time, wind farm managers were struggling to find a wind turbine gearbox lubricant capable of delivering superior protection without requiring frequent and expensive changes. Fully appreciating the challenge requires understanding how a wind turbine gearbox works.

Wind turbine gearbox 101

If you’ve ever driven past a wind farm, you’ve noticed how slowly wind turbine blades turn – typically 10-18 rpm. The generator inside the turbine’s nacelle (the housing atop the tower), however, requires up to 1,500 rpm to produce the turbine’s rated power. The gearbox increases rotational speed from the low-rpm turbine blades to the highrpm electric generator. It uses a variety of planetary gears, helical gears and bearings to accomplish this.

All those moving parts must withstand tremendous torque and high speeds while operating in hot, humid, wet environments or sub-zero temperatures – sometimes all of the above throughout the year. Gear lube can quickly fail in such conditions.

That was precisely the case with the predominant windturbine gear lube on the market at the time. It tended to absorb moisture, which led to additives separating from the lubricant (called additive dropout). This leads to a form of fatigue failure called micropitting that can cause gears to fail. In fact, at that time, a wind-farm manager could expect 30-40 percent of the gearboxes in his turbines to fail within three to five years. This is unacceptable considering that, along with crane costs, replacing a wind turbine gearbox costs up to $500,000.

To help prolong gearbox life, managers resorted to frequent gear-lube changes – typically every two to three years. That may not sound unreasonable until you understand the toll a single lubricant change takes. First, the turbine has to be shut down, which reduces profitability. A team of trained technicians must then mobilize a specially designed truck capable of pumping the new lubricant to the gearbox (up to 300 feet above the ground) while draining the old oil. Not only that, the gearbox requires flushing to remove contaminants, which adds additional time and complexity. Changing oil in just one gearbox can cost thousands of dollars. Changing oil in every gearbox on a wind farm quickly becomes cost-prohibitive.

Building a better lubricant

We went to work developing a better gear lubricant. In addition to years of lab testing, the lubricant was installed in seven wind turbines located in the Midwest. The turbines had been using a competitor’s oil and were in rough shape. In fact, the wind farm manager later told us he had expected the gearboxes to fail within six months of testing. Instead, the AMSOIL product performed well and the turbines continued running. We monitored lubricant and turbine performance every month.  The process uncovered several costly hurdles to servicing wind farms. For example, personnel must complete safety training, earn certification and carry millions of dollars of liability insurance simply to set foot on a wind farm, let alone climb a tower. In addition, wind farm managers expect suppliers to act as technical consultants and help them develop procedures for improving efficiency. We quickly realized that servicing wind farms requires a team of full-time, specialized experts. That’s why we handle sales to wind farms corporately rather than through independent Dealers.

Despite years of severe service, the lubricant continued performing flawlessly. In total, the lubricant was in use for nine years without being changed and without incident. Recently, the wind farm elected to decommission the seven turbines to perform infrastructure upgrades; however, the lubricant was still in great condition and performing well until its final day of use.

Our test data impressed the biggest and most prestigious manufacturers in the world. We have since earned approvals from nearly every major turbine manufacturer and gearbox manufacturer, including Siemens*, Vestas*, Flender*, Nanjing Gear* and ZF*. This was a huge step since wind farm managers won’t use non-approved oils in their turbines given the astronomical costs should something fail. Our gear lube is also the factory fill for one of the world´s largest turbine manufacturers, as well as the run-in oil at nearly every major gearbox OEM that supplies the global wind industry. We continue to work toward earning more factory-fill agreements.  AMSOIL products are now installed in nearly 50 percent of all wind turbines in the U.S., in addition to turbines in Europe, China, India, Brazil and more. We’re proud to say that AMSOIL products have never caused a gearbox failure. That’s a tremendous achievement considering the state of the industry prior to our arrival.

What good is it for me?

You might be thinking, “That’s great for AMSOIL INC., but how does it help my Dealership?” There are several ways.

1) Increased expertise influences all AMSOIL products

The insights we’ve gleaned from our involvement in the wind industry influence additional product formulations. For example, we applied the advanced chemistry of our wind-turbine gear lubricant to the passenger car/light truck market via SEVERE GEAR® Synthetic Gear Lube. The chemistry that impressed the toughest critics in one of the world’s most demanding industries influenced the chemistry in each easy-pack of SEVERE GEAR. Developing and testing synthetic technology in wind turbines builds our knowledge and helps us continue to improve our full line of world-class synthetic lubricants.

2) Brand validation

Our leadership role in the wind industry strengthens the AMSOIL brand and helps validate your efforts in the field. Additionally, it shows that our size and influence is larger than some people think, boosting your credibility. Tell prospects and customers that the biggest and most prestigious manufacturers in the wind industry selected AMSOIL from all the lubricant manufacturers in the world to develop a gear lube for their gearboxes. Point out that AMSOIL lubricants are installed in nearly 50 percent of U.S. wind turbines. This level of credibility speaks volumes about our product quality. Ask prospects, “If AMSOIL synthetic lubricants perform that well in wind turbines, imagine how well they can perform in your vehicles and equipment.”

3) Improves company image

While it may not be at the forefront of many enthusiasts’ minds, many customers actively look for companies that support sustainability. By servicing renewable-energy assets and maintaining a leadership role in the industry, we strengthen our image, which reflects well upon Dealers.

4) Helps keep costs down

A single wind farm can require thousands of gallons of lubricants. To meet demand, we purchase increased volumes of raw materials at a time, helping reduce purchasing costs. Manufacturing to meet increased demand also leads to greater production efficiency, which further holds costs in check. We pass the savings on to you and your customers.

We plan to continue growing our presence in the wind industry. It’s a key part of our strategy to diversify and strengthen the company, which ensures the viability of the Dealer opportunity for years to come.

WHY CAN’T DEALERS SELL TO WIND FARMS?

We’re as committed to the Dealer opportunity as ever. But explosing Dealers to the financial and safety risks inherent to the wind industry would be irresponsible. For the following reasons, it’s best for everyone that we handle the wind market corporately.

CUSTOMERS REQUIRE UNPRECEDENTED SERVICE

Selling lubricants is just the start. Businesses must sign complex terms-and-conditions agreements and carry expensive insurance policies. They must also maintain a large inventory of products while providing payment terms. In addition, businesses are expected to develop oil-sampling procedures, obtain oil samples and create gearbox-flushing procedures, among other value-added services. A business is seen as a partner available to help wind-industry personnel uncover ways to maximize turbine efficiency. It must provide on-site technical analysis and actively work to advance the industry, not just sell lubricants. Simply entering a turbine is dangerous and requires extensive training and certification. These restrictions are in place to ensure maximum safety when working in turbines 300 feet high and beyond.

THE MARKET REQUIRES SPECIALIZED KNOWLEDGE

Gearboxes and other components use cutting-edge technologies accessible only to industry experts. Personnel must understand particle-count testing, oil analysis interpretation, troubleshooting and other complex disciplines. Mechanical failures resulting from incorrect product recommendations, for example, can carry liability costs in excess of $500,000 per turbine. Dealers aren´t positioned to absorb this level of risk.

THE MARKET CONTAINS RELATIVELY FEW POTENTIAL CUSTOMERS

While growing, the wind market contains a relatively small number of potential accounts compared to traditional markets. Pursuing a wind farm not only will lead to disappointment, it will distract Dealers from approaching potential customers they’re much more likely to secure.

While there are Dealers who are fully capable of executing aspects of doing business with wind farms, the overall demands and liabilities are too great.

 

AMSOIL has never caused a gearbox failure. That’s a tremendous achievement considering the state of the industry prior to our arrival.

Should I Change Fluid in a Filled-for-Life Transmission?

What’s up with these “Filled-for-Life Transmissions”?

Casual motorists generally take no interest in crawling under their vehicles on a Saturday afternoon. And, when was the last time you heard someone express excitement over dropping their car off at the dealership for maintenance?

The automakers know this, which explains the proliferation of sealed, or filled-for-life, transmissions and differentials. Many vehicles also use “lifetime” factory fill fluids in these components that supposedly don’t require changing. Some transmissions and differentials don’t even include dipsticks or access plugs for checking the fluids.

The dirty little secret is that “filled-for-life” really means “filled for the life of the warranty.”

Suppose the “filled-for-life” transmission or differential on your truck fails after the factory warranty has expired. What do you think the dealership is going to do? That’s right – slide a bill across the counter to the tune of several thousand dollars.

It’s a good idea to change fluids in a filled-for-life or sealed transmission or differential at least once during its lifetime, and more often if you tow or haul. Here’s why.

Big power = increased heat

Modern vehicles are tougher on transmission fluid and gear lube than ever. For starters, the automakers are in an endless arms race to produce more power than the competition. All that added power has to go through the transmission and differential before reaching the wheels, yet modern transmissions are smaller and lighter than their predecessors. Meanwhile, the gears and bearings in most differentials remain unchanged despite the increased power they must handle.

This adds up to increased heat, and heat is one of the transmission fluid’s biggest enemies. It speeds the oxidation process and causes the fluid to chemically break down. Fluid that has broken down can cause sludge and varnish to form, which clogs narrow oil passages and can lead to stuck valves. Soon, your vehicle can begin to shift hard, hesitate or quit shifting altogether.

The situation is just as dire downstream of the tranny where heat and pressure wreak havoc inside the differential. Towing and hauling increase friction, which in turn increases heat. Extreme heat causes the gear lube to thin, reducing the effectiveness with which it keeps gear teeth separated and prevents wear. Thinner gear lube further increases friction, which causes heat to increase in a vicious cycle known as “thermal runaway.”

Lighter fluid, and less of it

Components also use lower-viscosity fluids to help boost fuel efficiency. That translates into thinner fluid protecting against intense heat and wear – not an easy task. In addition, many automakers use less gear lube than before to help reduce energy lost to friction and boost fuel economy.

Given such challenging conditions, what’s the best way to combat heat and stress to ensure your vehicle keeps running strong? Never change the fluids? Hardly.

“Filled-for-life” is misleading

In fact, your “lifetime” fluid may require changing if your driving habits full under the “severe” designation, which includes towing and hauling.

The differential in the 2016 Ford Super Duty 250, for example, is considered “filled for life.” However, the owner’s manual instructs you to change the fluid every 50,000 miles (80,467 km) in “severe” conditions and anytime the differential is submerged in water.

Did you hear that, anglers?

The 2017 Toyota Tundra likewise features a “filled-for-life” differential. But Toyota tells you to change fluid every 15,000 miles (24,140 km) if towing.

Complicating matters, some vehicles don’t even include a service schedule for changing transmission fluid. The Mazda CX-5 is one example. That doesn’t seem like a great idea if you plan to keep the vehicle past its factory warranty period.

For maximum life and best performance, change the “lifetime” fluid in your vehicle’s filled-for-life or sealed transmission or differential at least once, but more often if your driving conditions fall under the severe designation.

Changing fluid in these units may tax one’s mechanical aptitude, but it can be done. You likely need to visit the dealer or a mechanic since special tools can be required. Some manufacturers also prescribe complicated procedures spelled out in a service manual for changing fluids.

Anyone who has changed gear lube before – whether on a “filled-for-life” differential or traditional unit – knows the hassle involved: a tough-to-reach fill hole, gear lube spilled everywhere and bloody knuckles.

Find out how often to change gear lube here.

Our SEVERE GEAR easy-pack offers the perfect solution. Compared to rigid conical bottles that waste a quarter of the gear lube or more, our easy-pack offers the dexterity to maneuver around vehicle components and the flexibility to install nearly every drop of gear lube.

Severe Gear®: The Right Tool For The Job

Worlds Best Differential Oil – SEVERE GEAR®:

Here in Sioux Falls we have to stock more and more all the time. makes me wish I bought a several pallets back way back when.  But it makes a HUGE difference. Temperature alone!

Your vehicle’s differential is likely not top of mind while hauling snowmobiles or ATVs for a fun weekend on the trails. Unfortunately, towing is in the severe service category and places extreme stress on your drivetrain. Today’s vehicles produce substantially more horsepower, torque and towing capacity than their predecessors, yet the design of differential gears and bearings remains largely unchanged. Many differentials even use less gear lube and lower viscosities than before in an effort to reduce drag and increase fuel economy. In essence, less gear lube is responsible for providing more protection.

Fighting the Grind

Differential designs have inherent weaknesses. In a traditional automotive differential, the pinion gear concentrates intense pressure on the ring gear. As the gear teeth mesh, they slide against one another, separated only by a thin layer of lubricant. The repeated stress the lubricant film bears can shear gear lubes, causing permanent viscosity loss. Once sheared, the fluid film weakens, ruptures and allows metal-to-metal contact, eventually leading to gear and bearing failure. The situation is amplified by severe-service applications like towing.

Thermal Runaway

The extreme pressures and temperatures placed on gear lubricants can lead to a serious issue called thermal runaway. As temperatures in the differential climb, some gear lubes lose viscosity and load-carrying capacity. When extreme loads break the lubricant film, metal-to-metal contact occurs, increasing friction and heat. This increased friction and heat, in turn, results in further viscosity loss, which further increases friction and heat. As heat continues to spiral upward, viscosity continues to spiral downward. Thermal runaway is a vicious cycle that leads to irreparable equipment damage from extreme wear, and ultimately catastrophic gear and bearing failure.

How Often Should I Change Front or Rear Differential Fluid?

When to change differential fluids

 

It depends on your vehicle, driving conditions and differential fluid quality.

That’s a pretty vague answer, but it’s true.

If you drive your truck primarily on the highway in temperate conditions and rarely tow or haul, you likely don’t need to change front or rear differential fluid very often. But, if you tow a work trailer or haul supplies frequently and the temperature fluctuates as wildly as your health insurance premium, then you need to change the fluid more often. The only way to know the exact mileage interval is to check your owner’s manual or visit the dealership.

Bigger, faster, stronger

Why the varying fluid change intervals? Because severe operating conditions break down differential fluid more quickly and place greater stress on the gears and bearings, inviting wear.

The truck manufacturer’s ongoing arms race for the highest towing capacity has resulted in trucks that place far more stress on differentials than their predecessors. Meanwhile, differential fluid capacities have largely decreased or remained the same.

For example, compare a 1996 Ford F-250 Crew Cab to the 2017 version. Back in 1996, maximum towing capacity was 10,500 lbs. using a rear differential that held 3.75 quarts of gear lube. The 2017 model offers a 15,000-lb. towing capacity using a rear differential that holds 3.5 quarts of fluid.

Greater towing capacity, less gear lube

What does that mean for your truck? It means less fluid is responsible for guarding against increased heat and stress. In this environment, inferior lubricants can shear and permanently lose viscosity. Once sheared, the fluid film weakens, ruptures and allows metal-to-metal contact, eventually causing gear and bearing failure.
And in Sioux Falls looking out over 12th St every day, I see a lot of people overloading their light duty pickups!

Increased temperatures are also a challenge. As temperatures climb, gear lubricants tend to lose viscosity, while extreme loads and pressures can break the lubricant film, causing increased metal-to-metal contact and heat. The increased friction and heat, in turn, cause the lubricant to lose further viscosity, which further increases friction and heat. Friction and heat continue to spiral upward, creating a vicious cycle known as thermal runaway that eventually leads to greatly increased wear and irreparable equipment damage.

That’s why you need to change differential fluid more often in severe operating conditions.

In our example above, Ford recommends changing differential fluid every 150,000 miles in normal service. But they drop the change interval significantly – to every 30,000 miles if using non-synthetic fluid – when towing frequently at wide-open throttle and driving at temps above 70ºF. Those restrictions apply to just about anyone who’s pulled a camper/boat/trailer anywhere in North America during most of the year.

Bottom line…

Use a high-quality synthetic gear lube to maximize your truck’s ability to tow and haul.
