Что внутри сгоревшего вариатора Toyota Raize? Подробный разбор и ремонт

Video Navigation: 00:00 Start 00:04 Toyota Raize CVT Diagnostics 01:03 Vehicle Inspection Oil leaks detected from the CVT, presumably through the breather. CVT oil has a burnt smell. 02:23 Error and Problem Analysis CVT error and faulty CVT temperature sensor. Oil temperature shows 80 degrees. 05:33 Oil pan removal 08:20 Filter and wiring inspection Filter melted, missing felt. Wiring melted. 10:49 CVT Removal Signs of overheating are visible, wiring has melted. Markings are burnt, pump drive shaft is blackened. 12:55 Looking Inside 21:19 CVT Troubleshooting 23:00 Disassembling the A2N CVT 25:14 Assessing the A2N Pump The pump is disassembled to assess wear. The pump cover is lifted by the gear, the metal is pulled. No filter felt was found, presumably dissolved in the oil. 27:00 Bearing Issues and Updating A2N and N2N Pumps Toyota Raize CVT pumps often wear out due to the rocker gear and bushing seizing. 33:17 Valve Body Issues The valve body has many issues, including melted solenoids and stuck valves. Chips and friction deposits in the passages. 37:27 Assembling the A2N CVT Assembling a new CVT using parts from the old one. - The differential and housing are replaced with new ones. The pump is modified to prevent seizure due to overheating. 43:26 Operating principle of A2N and N2N CVTs 47:28 Clutch pack The gear is engaged by a clutch pack. Gear shifting may be jerky due to hydraulic problems. 48:28 Risk of slippage Risk of slippage under starting loads and with a small belt radius. Dirty oil and worn hydraulics increase the risk of slippage. 49:56 Beginning assembly of the starter-reverse unit Assembly of the starter-reverse unit: two forward gears and one reverse gear. Using drum brake clutches. Demonstration of the reverser pack, which provides braking for the entire drum. 50:52 Planetary Gearbox Description of the planetary gearbox components: sun gear, planet carrier with pinions, and ring gear. The planet carrier with pinions is in constant mesh with the outer drum. The sun gear meshes with the driven cone, and the ring gear meshes with the output gear. 53:01 Operation in First Gear 55:01 Problems with A2N and N2N CVTs CVTs often fail at low mileage, for example, at 7,000 km. Some units last up to 100,000 km, but their safety margin is limited. 56:01 Mechanical Assembly The CVT can withstand the high loads of a turbocharged engine. Non-turbo CVTs operate at lower temperatures. 58:14 Parking Mechanism Description of the parking mechanism: parking gear and hook. Recommendations for using the handbrake when parking on a slope. Inability to engage park while driving due to design features. 01:00:12 Consequences of hard braking on A2N and N2N CVTs Hard braking can cause CVT failure: broken input shaft, belt slippage. After an accident, the CVT belt may slip due to a single slippage of the cones. 01:02:07 Replacing Seals and Oil Replacing the drive seals in the CVT and bevel gear. Adding oil to the pump oil sump to prevent the pump from running dry during initial startup. 01:05:11 Features of the A2N and N2N Valve Body and CVTs Valve body settings are designed for low-power vehicles. 01:06:22 Differences between the 1KR and 1KR-VE engines The 1KR-VE engine is different from the older 1KR engine. Installing a transmission from a different engine may result in a loss of vehicle performance. 01:09:55 Heat Exchanger Upgrade 01:15:00 CVT Installation and Cooling 01:17:59 Causes of A2N and N2N CVT Overheating 01:19:32 Pressure Calibration 01:21:34 Load Adaptation The adaptation process takes 50% of the time. Adaptation is faster than on the hybrid XTrail. 01:22:24 Pressure Calibration 01:22:51 Adaptation Results -After adaptation, the pressure in the secondary circuit is 1 MPa, in the primary circuit it is 0.5 MPa. 01:23:42 The Importance of Adaptation 01:24:41 Testing the Toyota Raize Idle temperature: 86 degrees. On an incline, the temperature drops to 82 degrees. 01:27:23 Testing in Traffic The fan turns on when the coolant temperature is 90–93 degrees. Oil temperature: 91 degrees. 01:17:59 Conclusion I'll answer any questions about CVTs! Our phone number: +7 (904) 629-11-88 Sergey Babinets Our website: https://variator-center-vladivostok.r...
