Meanwhile, the torque and, as a result, the safety factor of the clutch of the driven disk is a very important indicator.

[/caption] We prepared for the clutch expertise just like any other: in large stores we bought several running models: ZMZ-Turbo, GAZ, Tyumen Motor Builders OJSC and Krafttech. Having folded the boxes in a neat little box, they handed them over to US, to the clutch laboratory. The testers drew attention to the Tyumen kit: its driven disk did not carry any markings, in contrast to the casing, which had a laser mark.

All formalities are settled, experts launch their test benches and take indicators. When it came to measuring torque, it smelled fried. Three applicants met the norm, and the torque of the ZMZ-Turbo disk was 530 Nm, that is, the clutch safety factor was 2.2 with the norm of 1.3–1.5. The testers on this occasion expressed their point of view: “Clutch with a similar safety factor is more suitable for UAZs and gazelles. But it is undesirable to use it on ordinary Volga. "It can lead to a significant increase in dynamic loads in the transmission and cause the destruction of such units as gearboxes, drive axle gearbox, etc." It’s strange, usually dissatisfaction is caused by an insufficient supply, but here - on the contrary.
Nevertheless, we agree with this opinion. After all, the one who drives his Volga once a year to the country, and the other from the country, and does not carry anything bulky except his person, most likely does not need a crazy coefficient of adhesion. He is much nicer to shift gears without effort and squeeze a soft pedal. Another thing is the Sochi taxi driver, loaded with well-fed tourists and conquering Mount Akhun on the yellow "Volga" twenty times a day. He sleeps and sees a pressure plate with a high coefficient of adhesion.
So what to choose? If you have a Gazelle, which moves one and a half tons of tomatoes through the dunes, take the ZMZ-turbo, you won’t be mistaken. I want a “soft grip” - your choice of Kraft-tech. If you are guided by a low price, then GAZ.
