IF DISK IS STICK
Many of those who do not drive in the winter may encounter a mysterious phenomenon in their car in the spring: they cannot switch gears while the engine is running. It’s easy to panic, suggesting that the box “broke”. However, the reason is simpler: the clutch disc is stuck to the flywheel so tightly that it is not possible to disconnect them by pressing the pedal repeatedly. There are several methods known that allow you to separate the disk, of course, without removing and disassembling the mechanism. Boris SINELNIKOV reminds of them.
The basic principle is that the clutch disc and the flywheel must be informed of different speeds (frequencies) of rotation.
1. Warm up the engine and stop it. Turn on one of the gears. Press the brake and clutch pedals and, without releasing them, turn on the starter for a few seconds. If the clutch did not turn off (the starter did not rotate by turning the crankshaft), try again two to three times, allowing the starter and battery to rest for several minutes each time.
2. Another trick. Warm up the engine. Park the car so that it can immediately go unhindered, better downhill. Engage first gear and then starter. Since the engine is warm, it will immediately start working, and the car will start. Having accelerated, to start slightly, depress the clutch pedal and press the brake pedal. The transmission speed, and therefore the clutch disc, will decrease as the car decelerates, while the running engine (and therefore the flywheel) will tend to maintain or increase speed, obeying the gas pedal (you can press it with the toe at this moment) The difference in the rotational speed will cause the disk and flywheel to turn relative to each other and disconnect. If this does not happen, release the brake pedal so that the engine does not stop, raise its speed (and accordingly the vehicle speed) and press the brake pedal again. Repeat this until you get the desired result. Sometimes for this you need to drive a few hundred meters.
3. If there are no conditions to go on the road, imitate the movement by setting the rear of the car on the tragus. As in the previous case, start the warmed up engine with the gear engaged and, raising the speed, spin the rear wheels. Then depress the clutch and depress the brake pedal.
4. In cases where all the described methods do not give a result, use the force method - “stick mechanically” the adhered disk from the flywheel. For this, a hole is drilled under it in the clutch housing (on the Zhiguli it is placed, as shown in the figure, a diameter of 16 mm is convenient because the hole can then be plugged with a plastic stopper from a half-liter bottle). Through it, a chisel (or a powerful screwdriver) is hammered under the disk and, acting as a lever, try to separate the disk. The clutch pedal is in the “squeezed” position. If there is no assistant who presses the pedal, it can be fixed, say, with a stick, resting on the seat cushion. If it is not possible to separate the disc the first time, the crankshaft (and therefore the clutch disc) is turned so that another section approaches the hole. Repeat attempts until the disk is removed.
If it is possible to work under the machine, in all cases it is advisable to increase the effort to separate the disc by turning the rod out of the clutch slave cylinder as much as possible. Of course, then you need to adjust the free travel of the fork, which presses the rod.
