Piston rings 83.5mm set

Contains 01 complete set for 5 cylinder engine.
Compatible with SPA Super A, with 1.5mm / 1.5mm and 2mm channels.
Ring thickness:
1st ring 1.5mm - Made of carbon steel, which is 35% more resistant than cast iron and on average 30% lighter. With DLC (Diamond-Like Carbon) treatment, which is the application of carbon particles, whose physical and chemical properties are very close to those of the diamond, providing greater resistance to the material and reducing the friction of the surface, which significantly reduces friction when working against other surfaces.
2nd ring 1.5mm - Made of cast iron.
3rd ring 2.0mm - Manufactured in 3 pieces, which guarantees easy maintenance, better stability in the control of the oil film and improves the oil removal through the piston lubrication holes, as it has a better area for displacing this oil.

About CMD Extreme Pressure lubricants:

When the operation requires extreme pressure, all ordinary lubricants break down and allow metal-to-metal contact with consequent scoring, frictional heat, work and cutting tool damage.

They will not corrode the finest surfaces nor will they mulsify with cooling liquids. But these facts are not the most remarkable feature of CMD lubricants. The truly outstanding property of CMD is its ability to withstand extreme pressures!

CMD EXTREME PRESSURE lubricants are regularly used from 40,000 to 50,000 psi.

        Good book, mediocre edition
        Format: Paperback
        This review pertains to the quality of this edition's editing and construction, rather than the content of the book itself. Rest assured that the text itself remains a valuable piece of introductory theory. The book is fairly well constructed, with paper and a binding that is sturdy enough for general use. However, my copy had several manufacturing errors including folded over pages being stuck into the binding. In addition, there are several misspelled words throughout the text and some obvious typos (missing letters, incorrect capitalization and punctuation) that did not majorly impact the readability of the text, but were, nevertheless, annoying. Considering the low price of this edition the manufacturing errors are hardly a big deal, but I would have preferred the text itself to have been treated with more care and respect while being prepared for printing.

        thoughts on Xi Jinping
        Format: Kindle
        This book was highly organized and very easy to comprehend. I have formed a much better understanding of Xi Jinping and where he is taking China. Although I feel he has been thoughtful and successful in some areas such as improving China economically, I don’t feel his autocratic approach will succeed in the long run when more Chinese people will demand to be heard. Just as Mao thought didn’t outlast Mao, Xi thought will not outlast Xi.

        The Book I Meant to Write
        Format: Kindle
        While doing my master’s degree in international relations, I completed a master’s thesis on Xi Jinping Thought (which, like the authors, I shortened to Xi Thought). I considered writing a book on the subject since there wasn’t a lot in English, but I no longer feel the need. This book fills every gap that was present. Well written and informative, it is the quintessential English source in Xi Thought. The authors put Xi’s political thought in a consultative Leninist paradigm and define that context clearly. Each chapter elucidates a little more and puts Xi thought front and center in China’s current transformation. I consider it a must read.

        Great read and most importantly very topical
        Format: Audiobook
        The writers use published work of Xi and Chinese government official statements to describe the true nature of this most important Chinese leader who will have profound impact on the total world.Like it or not it is essential for all of us to really what he is preparing his nation for the vision he has.Americans are naive and totally ignorant.

        Pure anti-China propaganda
        Format: Audiobook
        From the first few sentences they get the name of the ruling party of China wrong and it only gets worse from there. This is purely a work of western propaganda and in no way academic or objective. I've studied China for many years. You will find nothing of value from this book. All of their achievements are minimized or disregarded entirely. You will also notice that very little data is presented if any at all.
