There is an opinion that modern “mechanics” are practically indestructible. And indeed: if operated properly, the box can travel more than 400,000 km, and the same with a
If the car is not equipped with an armrest between the front seats, the driver must find a place for his right hand. It is uncomfortable to hold it on the handlebars, because the elbow hangs in the air without support, and after a few hours of driving the muscles begin to ache. This places the hand on your lap or on the gear lever.
Bored, the drivers caress his head, play with it in their hands, beat the rhythm of the music and thereby find at least some form of entertainment. Some even use the handle as a stick to change their riding position and move from one side to the other. The lever is therefore pressed down with force.
Even driving instructors at driving schools advise to keep your hand on the gear lever. This way you better understand which stage you are on and you don’t have to search for the lever with your hand, which always greatly simplifies driving for an inexperienced driver. However, if you also drive not in a training car, but in your own car, and even constantly, then you can cause problems with the equipment.
If you are not too lazy and read the operating manual, you will find that it is forbidden to keep your hand on the manual transmission! In addition, this inscription is accompanied by a black frame and an exclamation mark, indicating the extreme importance of the warning. The fact is that the gearbox selector is directly connected by rods to the mechanical part of the transmission and any external force goes into the depths of the latter, on the gears and shafts. And they are so loaded that even a little extra pressure leads to disaster.
Most often fly synchronizers – mechanical devices that ensure smooth switching. When the driver moves the lever, the synchronizer equalizes the rotational speed of the gear and shaft and brakes the main gear thanks to a special friction ring placed on the cone. This ring works under tension, and the more a person presses on the handle, the greater the friction force in the synchronizer.
After the gear is engaged, the synchronizer disengages and rotates freely with the clutch. Right now you can’t touch him. Pressing the synchronizer while the gearbox is operating will create additional frictional forces in the clutch, causing wear on the friction ring, and the diamond-shaped teeth of the clutch will shift and grind in the wrong places. In short, the synchronizer will wear out.
And after just a few months of such abuse, the friction ring will wear out and no longer effectively brake the gear; a grinding noise will appear when you engage a gear, like an old ZIL or a passenger PAZ? Then the broken clutch teeth will completely stop holding the load, causing the box to begin to disengage the gears. This usually happens when you release the accelerator pedal, as soon as the torque on the axles disappears. I dropped the pedal and the box shoots the lever back. And then you will actually have to constantly hold it with your hand so that the car can somehow continue moving.
Repairing synchronizers is a complicated matter. You need to disassemble the box, remove the axles and go through the entire mechanical part. Tradesmen complain that damage to synchronizers now ranks first among all mechanical transmission failures. They need to be replaced more often than bearings and shaft seals.
This means that the culture of driving has declined sharply. Therefore, to prevent playful hands from getting into trouble and destroying the box in advance, we must find its proper use. For example, instead of the manual gearbox lever, it is better to use a wrist expander or install an armrest in the car. Luckily it’s cheaper than half a box.
