The bearing does not withstand, wear, microplay appears, the shaft warps, generating vibrations and provoking further destruction of the bearings. Chips get into the oil, clog the pressure reducing valve responsible for maintaining oil pressure. And without standard pressure, the belt slips even more and wear progresses.
It is even more dangerous to drive fast on snowy roads. On slippery surfaces, small slips occur. At the peak of power, the differential either cuts off traction, then returns it to the loaded drive wheel, shock loads appear and, as a result, scuffs on the pulleys and belt slippage. In general, the faster drivers drive, the less their CVT will last.
The towing device is contraindicated in XRAY and Vesta CVTs. The box can hardly cope with the 1.2-1.3 ton weight of these cars, and the additional 750-kilogram “cart” generates prohibitive loads for the transmission, provoking belt slippage and vibrations that break the bearings on the shafts and on the pulleys. It is better not to buy cars with a towbar and with a variator in the secondary market.
Swinging and slipping
On the Vesta and Xray variators, a break in the gears of a two-stage planetary gearbox is sometimes recorded. Damage is caused by attempts to rock the car when slipping. If you change modes D and R with a sharp addition of gas, by analogy with a manual gearbox, then the box will not last long.
