This video shows the construction and function of a CVT steel push belt. A disassembled CVT push belt is reassembled showing all 423 pieces! 399 Elements and two ring packs with 12 bands each.

This video helps satisfy 2017 NATEF MAST Task A2.C.4. "Describe the operational characteristics of a continuously variable transmission (CVT)", a priority 3 task.

This is still the best CVT belt explanation on YouTube. Amazing considering it was done 6 years ago.

[johnet]

Best explanation of what is inside of a cvt. Many presenters talk to fast, this was easy to listen to and understand.
thank you

[kiantatchong]

Fascinating. The push concept is really ingenious. I always wonder how the belt can handle so much force when being pulled and now I understand. It is not pulled but pushed.

[grabasandwich]

I had never heard of a push belt til now! Guess I was living under a rock. Cool video 👍🏻

[Deucetrinal]

Thank you for making such a great clear and simple video about such a cool piece of engineering. All of the preparation with the labels and the different pieces spread out and then assembled right in front of our eyes is incredibly helpful to understanding how these go together. You really have a talent for communicating complicated concepts in a clear way. I look forward to your future videos!

I've long since retired from the auto mechanics trade. After several surgeries I now walk with a cane and can't do it for a living anymore. But I do work at an auto parts store where I sell Auto Parts and hand out advice. Your videos help me to advise my customers properly. Thank you!

I am on my 3rd Honda Accord Hybrid and really feel the technology is fascinating by simply using inertia and centrifugal force to engage and transfer energy to drive gears...your explanation was very digestible and clears up the hybrid "mystery"...Thank You

I recently bought my first car with a CVT transaxle and I was looking for a proper explanation on how the push belts are made. Thank you for clarifying it for me. I got yourself a new subscriber. Greetings from Brazil.

[johngreen]

Thank you for your time spent in making this video, the best I've seen on the description of the components in a modern CVT belt.

[TATiSWEAR]

Thank you for uploading this. I've wondered how a cvt belt could keep up tensile forces, I find it cool that instead its compression instead.

Good explanation. Nice clear camera work. No wasted blather. Very refreshing. Thanks.

AMSOIL's CVT fluid has doubled the life of all our clients belts and transmissions. Amazing find!! Nissan and Audi customers need to switch before 75, 000 miles. It keeps the friction while allowing smooth shifts and stops all wear. It took them 4 years to get it perfected thus it came out a little late but better than never.

[reyandy]

Wonderful presentation that was informative and timely! Your video solidifies the notion that these transmissions because of the belt are designed for a short life span. Thank you for the explanation. Keep up the good work!

[mrflamewars]

You are the transmission whisperer. It's so refreshing when someone actually values knowledge. (I live in Memphis, TN where NO ONE values knowledge or information of any kind)

[udiprimeassessoria]

This channel is definitely one of the reasons I learn English!
Every time I look for something about cars, the best videos, the best explanations,
They're definitely from here!

[matthewwain]

Note that it isn't JUST the number of rings that determine the strength and power they can transmit. It is the material the rings are made from (i.e. F6 or F7 etc), but also the width of the elements. Wider belts can transmit more torque. (i.e. 24 mm elements vs 28/30mm etc). p.s. I have found your video's EXCELLENT btw, thank you for taking the time to put them together.

[shaneohara]

I've had my little nissan for 11 years now, and she's running on 220k miles. Cvt still strong, and let me tell you, it's had a rough life... Got it new, and will keep it forever. She blows, I'll replace, but.... still hasn't

[Jesus.purple]

I would run as fast as I could from these cvt Rattle snakes!
Thank you for the demonstration.

[harumachiizayoi]

I understood the mechanism of the cvt belt well, I was suspected that the cvt belt was weak in the past, but I can ride with confidence with this, and the explanation was also polite and easy to understand. There is no such explanation in Japan. Thank you again.

[zukobringas]

All my curiosity about these metal belts was satisfied when you mentioned they were push loaded (compression) rather than pull (tension) as in rubber belts. Thanks a lot for the info.
