In this video I will clearly destroy the myth about 100% oil change in the variator, I will show and explain why it is impossible in principle with the procedures that are sold on the service market under the guise of 100% oil change in the variator. It's all about the design of the variator, as always. There are cavities in the variator where oil remains even when the engine is running or the oil change device is connected. These volumes are in the pistons of the cones and a couple of other places (I will disassemble and show), and in order to get the oil from there (change it), the cones must either close or open, or the hydraulic line must work, i.e. the working stroke of the cone and the pump must be completed. And the working stroke of the cone occurs only when the car is moving, or more precisely during acceleration, and the gear ratio of the cone pair is changed, and only then, all the oil that has accumulated in the cone(s) will come out and be replaced. And what do we have, pure marketing when they claim that this or that oil change will change the entire volume, all 100%. As you will see, it is far from 100%, not even close to 100%, all this is MARKETING about 100% oil change!!! How can I show this? I will simply completely disassemble the arrived variator, and drain the residual oil from the cones and other places where it remains, i.e. disassemble and drain into a measuring container, and show you this bucket of oil that can never be changed in the variator except by disassembling and assembling the variator. Hence the conclusion, change the oil more often and wisely. Appeal to the Couch Experts: Dear Couch Experts, I invite you to my service center if you have something to say and show on the subject. 00:00:01 Discussion of the residual amount of oil during replacement • The video discusses the residual amount of oil during replacement in the JF011E variator. • After draining the fluid and removing the filter, the remaining fluid will be shown. 00:01:55 CVT Disassembly • After draining the fluid, the variator will be completely disassembled and the remaining fluid will be poured into a clean bucket. • It will show how the remaining fluid is located in the system and the torque converter. 00:04:28 Valve Body and Residual Oil Volume • The valve body and the remaining oil volume in it will be shown. • It will discuss dust and dirt that can be in the system and how they affect the operation of the variator. 00:08:09 Valve Body Vacuum Test • The valve body will be flushed and a vacuum test will be performed to check its operation. 00:10:00 Starting reverse group • The starting reverse group, which starts the cones with a belt, will be disassembled. • The mechanism of operation of this group and its location in the variator will be shown. 00:11:58 Pump and pressure relief valve • The pump mechanism will be opened and the pressure relief valve will be shown. • It will be explained that this valve is not the cause of problems with the variator, but only a consequence. 00:14:45 Variator and its operation • The video talks about the operating principle of the variator, which consists of two cones and a belt. • The cones converge and diverge, changing the gear ratio, and the belt either goes more to the leading cone, or less to the driven one. 00:16:35 Changing the oil in the variator • When dismantling the variator, to avoid scattering the belt, it is pulled together with clamps. • The unit contains oil that remains after draining. 00:20:21 Belt quality and condition • The belt should be elastic, without cracks or crumbling. • If the belt is elastic and does not fall apart, then it is in good condition. 00:23:13 Comparison of hardware and standard oil changes • With a hardware oil change, more fluid is drained, but more money is spent. • With a standard oil change, the fluid is drained and cleaned, but without additional costs. 00:25:10 Conclusion • An oil change machine is only required in certain cases when a large amount of oil needs to be replaced. • In other cases, a standard oil change will be quite effective. #cvt #variator #oilchange I will answer any questions about Variators! our phone: +7(926)620-40-05 our website: https://cvt-master.com/zamena-masla/?... our VK: https://vk.com/remontvariatorov our YouTube: / cvtmaster our RuTube https://rutube.ru/channel/24212625/vi... our Zen channel: https://zen.yandex.ru/cvt our telegram channel: https://t.me/cvt _master_remontvariatorov
