All rights reserved.Our hybrid has a CVT — does anyone know what the warning signs are for an impending failure and when it should be immediately taken to a mechanic other than oil leaks? They are expensive to fix so any advice on interceptive maintenance would be helpful too most service managers seem to know little about them. If it is a Prius, the cvt is not the same as the belt driven unit on other ICE cars. Just do regular routine maintenance. A regular transmission is very expensive to fix too.

Relax, be happy. We have a Escape. Other hybrids including the Prius have a similar design. A regular or automatic tranny can be fixed or it can be replaced with a junkya … I mean, recycled gearbox at substantially less cost than a CVT BTW. What makes you think you have a problem? Have you had the gearbox oil changed? Preventive medicine is the best medicine, and it always helps to know warning signs.

We hope to keep our car for many more years and this question is more about getting preventive information than about diagnosing any problem on our car. And yes, we have serviced the car as recommended by our dealer. They do seem to be used for lower-power engines, which may also mean they are inherently less sturdy than a regular transmission.

Polaris Drive Belt Survival Guide

You have pretty much answered your own question. It will be a factory rebuild, just like a CVT. You have a CVT, therefore you have a problem. It got worse. I live in central TX, and my parents live in Phoenix.While these failures can be expensive to fix, the majority of them can be easy to prevent. The easiest way to extend your belt life is to use the low gear drive range when you are not operating the vehicle at high speeds. The clutches on most CVT systems incorporate fan blades into the clutch design, and the faster the clutches spin the more air they circulate through the belt drive housing.

By operating the vehicle in low range, not only are you applying less stress to the belt, but you are also moving additional cooling air over the moving parts. That keeps them cooler and helps them to last longer.

The second most common failure that we see is hourglassing of the belt. The term hourglassing comes from the way a belt looks after this failure has occurred.

If you turn the belt sideways you can see that it goes from being full width, to being narrow where it is burned, and then back to full width again. The most common cause of hourglassing a belt is when the vehicle gets stuck and the operator applies full throttle to get the vehicle to move.

When this happens, the drive clutch will spin at full speed, but as the belt is not moving, the clutch will overheat the belt where it contacts the drive clutch which then hourglasses the belt. If you do get stuck, and applying throttle is not moving the vehicle, then either use your winch to extract your vehicle or have another vehicle tow you to a point where you are no longer mired in the mud, sand, or water.

There are other causes of drive belt failures such as getting water in the belt drive hours, or not keeping the air filter for the CVT housing clean, but they only make up a small percentage of the drive belt failures that we see.

Below is a drive belt failure analysis poster that Polaris provides to dealerships.


This poster displays images and causes of the most common drive belt failures. Thank you. This is the most informative article I have read. I have talked to different dealerships and get told conflicting information. I just purchased my unit used great deal and wanted to be sure I was driving it correctly. Just puy a new cvt drive belt on my polaris ranger midsize in high range it stays in low range Before I installed the new belt it was working fine.

Thank you for an informative article. Could you please elaborate on how the belt drive could end up being an expensive fix? OEM Belt prices can differ quite a bit. It really comes down to the individual.

CVT Belt Tips

Good question, thanks for asking. However, when I am coasting to a stop, there is a very loud growling sound when I hit 10mph.

Could it be the belt? If they have been hourglassed look at the image on this blog post then you will feel a thump thump thump as you are driving along on a smooth surface.Many times, people experience issues with their car transmission, but they may not pay attention to it, as they are unsure or unaware of it. Yet in the opinion of experts, it will be best to address the problems with transmission early on, so that you can avoid transmission failure and bigger issues along the way.

As the automatic transmission of your car is an always-working part, there can be many early warning signs that you need to watch out for.

Below are some of the important signs of CVT transmission problems.

If you see pinkish oil leak marks when you move your car out of the parking area in the morning, it can be a classic sign of trouble. Transmission experts say that a CVT transmission can leak from about twenty external seals, some of which are very easy to repair and fix, whereas others will need complex services. Do you feel a bucking or shaking feel while commuting at high speeds?

There can be two reasons for that, the first being a poor tuning and the second due to a malfunction in the transmission system of the vehicle. So if you feel shaking or vibrations while driving your car, take it to an experienced mechanic and get the vehicle transmission checked. If you sense a burning smell when you are near your car, it can be a sign of an overheating transmission.

The burning smell can also be caused due to the transmission fluid leaking into the exhaust system. If the burning smell is caused by the leak of transmission fluid to exhaust system, it should be addressed immediately. Transmission slip is a situation where the engine is revving fast but the complete power is not transferred to the wheels. There can be a number of reasons for transmission slips and it would be better to take your ride to a technician for a checkup before things get worse.

Transmission Slips Transmission slip is a situation where the engine is revving fast but the complete power is not transferred to the wheels.If the belt breaks, you could be left stranded on a trail ride or quickly DNF a race.

There are many ways to prolong belt life that depend on proper break-in, using the correct clutch set up and most importantly driving style. Here we will show you how to inspect your current belt and show tips for installing your next one. This is a brand new belt. The area you want to pay close attention to is between the bumps on the underside.

Before installing a new belt it should be washed with warm soap and water and scuffed up with a green Scotchbrite pad. The clutch should be scuffed up too then cleaned with rubbing alchohal.

Keep in mind when you install a belt, The label should be able to be read from the top in the correct direction. This belt would make an excellent spare or reused.

This belt only had miles on it when it failed.

It was on a heavy 4-seater that had lots of different drivers behind the wheel. We felt it break apart just as we got on the gas coming out of a corner so we quickly stopped. The best way to prevent belt failure is to never hold the engine and belt in the same rpm range more than ten seconds. You want to modulate the throttle so the belt rides on cooler parts of the clutch sheaves.

Rolling on the throttle when coming out of corners instead of flooring it helps too. We put over miles on this belt and were very easy on the throttle.

It was installed in a lighter weight RZRS. The belt is showing signs of wear and should be replaced. The shape of the angled groove dictates engine braking. View the discussion thread. Skip to main content.

Luckily, Nissan would go on to address most of those concerns…. Here we are 15 years later and those same complaints plague Nissan owners. Rather than ironing out the kinks, Nissan executives have apparently been too busy ironing out their stacks of cash. A CVT uses a steel belt or pulley system to move gears in a continuous ahhhsmooth motion.

But the reviews from actual owners are a lot less rosy. Low speed acceleration is a particular trouble-spot for this CVT. According to owners, their vehicles will shutter and shake while getting up to speed. My transmission was reprogrammed at 12k miles.

Drove well, no issues and all scheduled maintenance done regularly at the dealer. At 65k transmission started shuddering and then vehicle would stall and die in traffic, very dangerous. Vehicle was sent into dealership three separate times, for engine pulley, reprogramming, completely new ECM. Each time the car ran worse. The vehicle is the worst I have ever owned, and would never buy another Nissan due to this.

The TSB, which was written for the Murano, tells mechanics to check for these conditions if an owner complains about hesitations:. One of the reasons for all that shaking might be an overheating.

Nissan has been accused of using an inadequate cooling system for their transmission. As the CVT heats up it can vibrate excessively. And when it overheats it sends the car into fail-safe mode which limits engine RPMs as it tries to prevent damage. This can leave drivers in a dangerous position, and is one of the complaints in a Sentra Xtronic Lawsuit.

CVTs are, by design, going to feel different when you cram the accelerator to the floor. While a geared transmission will typically burst off the line, a CVT has a much smoother and slower increase to maximum power.

Some go so far as to call it a safety hazard when trying to merge onto a busy road. CVT whine is a common problem and not unique to Nissan vehicles. Javascript is required to watch this video on our site, but you can try watching it on YouTube instead. It got worse every summer and even would suddenly stop accelerating.It has been said that to a camera or the common observer, tires are a bunch of round black things.

That is doubly true of CVT drive belts. But even if they look the same, all belts are not equal. Belt technology has had to increase as power output of CVT-equipped machines has gone up. A CVT belt is a type of V-belt. As such, it is the side of the belt that is doing the work. For that reason, the angle of the side of the belt must be compatible with the faces of the CVT.

The width of the belt must be precise as well. A belt has to be strong along its length. That is what is happening inside your transmission. The only connection between the two is the belt. WHY AND HOW In addition to being strong along the length, the belt must be rigid and highly resistant to bowing from side to side, but bend easily along the length of the belt. First, it has to transmit all the power the engine can put out. This means there can be over pounds of squeeze force trying to crush the belt from the sidewalls.

It does all this while running at temperatures ranging from minus 30 to over degrees. The cog on top also aids bending around the pulleys, but adds side-traction, making the cross section strong and generating cooling air in the CVT case. Between the top cog and the inner cog is the cord. The cord gives the belt the strength lengthwise. The cords are bound into the fiber-reinforced rubber of the cogs with adhesive.

The face of the cogs has a fabric cover. With all of the loads facing modern CVT belts, the search for materials that will perform better is constant. Better compounding, adhesives and the tensile cords are all continuously scrutinized. High-end SxS racing, high-horsepower machines with paddle tires, and mud-boggers with tall, aggressive tires are the hardest machines on CVT belts. Snowmobiles use a similar clutch, make incredible power and have a track that puts a heavy load on the belt.

But, a snowmobile belt is used in the cold and without a confining belt case aside from the body of the machine. It is interesting that mud-bog runners are considered tough on belts. One of the points that Dayco makes is that snorkels on machines hamper the cooling. Adding length or bends to the CVT-case breathers harms cooling. Engine mods, big tires and a heavier machine all add to the heat that the belt must endure.

If you start to make changes like these, then EPI feels you need to make changes to the clutching to keep the heat down. These vents are critical to belt life. Running with them restricted by dirty filters, mud or whatever, including rodents will make the belt run hotter. The belt will not necessarily fail immediately, but the rate of breakdown of the rubber compounds is greatly accelerated when the environment is hot.

You can damage a belt going slow too. Running at low speed in high range can burn up the belt, and so can riding or driving with the brake on. The same thing is true when the wheels are stuck.

It may not fail right then, but belt life is shortened. Water, mud or dirt in the CVT case, and especially on the sheaves the drive faces of the clutchesall hurt belt performance and shorten the life of the belt.
