Video Navigation: 00:00 Start 00:00 Introduction and Description of the JF015E CVT • Overview of the JF015E CVT from Jatco. • Description of malfunctions and repair methods. • The CVT is a hybrid automatic transmission. 01:56 CVT Applications • Installed on various vehicles, including the Lada Vesta, Renault Megane, Nissan Juke, Qashqai, Kaptur, and Sandero. • The CVT is also used in the all-wheel drive configuration of the Suzuki SX4. 03:51 Causes of Failures and Their Consequences • Main failures: scuffing of the cones and belt. • Cause: insufficient pressure in the driven pulley. • The effect of high temperatures and loads on component wear. 08:33 Effect of Metal Shavings • Metal shavings circulate in the system, damaging valves and solenoids. • Damaged valves reduce pressure, causing belt slippage. • Irreversible wear and failure of the transmission. 11:06 Input Shaft Bearing Failure • Second common failure: input shaft bearing failure. • The bearing rotates at high speed and under load. • Ball bearings were previously used, which often failed. 13:26 Consequences of Bearing Failure • Damage to the Teflon seal and bushing. • The shaft begins to rub against the hub, damaging it. • Damage leads to noise and shaft damage. 14:26 Bearing and Hub Damage • Bearing failure leads to damage to the input shaft and hub. • Noises appear that coincide with engine speed. • Locking problems and stalling when engaging drive or reverse are possible. 14:55 Sun Gear Failure • The sun gear is used to engage first gear. • Failure occurs under short-term load, such as when the vehicle gets stuck. • The sun gear can detach from the hub, causing failure. 16:52 Housing Problems • Older vehicles with over 100,000 kilometers on the clock can experience housing problems. • Bearing seats become compressed, leading to wear and malfunction. • Housing replacement or repair is required, which can be expensive. 18:34 CVT Repair and Modification • Replacing split Teflon seals with solid ones with rubber seals. • Installing a reinforced belt with more strips to prevent tearing. • Using a reinforced roller bearing for the input shaft. 22:41 Pump and Housing Modifications • Installing a hard-coated repair valve. • Lining the bearing seats to prevent wear. • Installing metal inserts to prevent damage to the housing and cover. 24:23 Valve Body Repair • Disassembling and inspecting the valve body, vacuum testing. • Rebuilding and adjusting the solenoids for proper operation. • Testing the valve body on a rig to increase pressure and ensure stable operation. 25:42 Conclusion • The repair includes modifications to ensure long-term operation of the CVT. • The repair warranty is 20,000 kilometers or 12 months. • After repair, the transmission usually lasts longer.
