If the clutch fails when the gear is engaged, then to disengage it, you should release the "gas" and put the gear shift lever in neutral. If the gear is stuck, you can give a little "gas" so that the gear shift lever is released.
To drive with a faulty clutch, do the following:
- turn off the engine and engage first gear;
- turn on the starter and start the engine. The car will move jerkily until the engine speed matches the gear. If the engine is cold, it should be warmed up first so that it does not stall immediately. On a level road, you can drive in second gear to the nearest service station;
- if you want to try shifting from a lower gear to a higher one, start off as described in first gear, and then increase the engine speed to about 1000 min⁻¹. Release the gas pedal slightly and engage neutral. Then release the gas pedal completely and engage second gear. When the engine crankshaft speed and gearbox shaft speed are aligned, second gear will engage. If there was a lot of time to shift gear, then add the gas, simultaneously engaging the gear. Shifting from a lower gear to a higher one should only be done at low speeds, shifting, for example, to second gear at about 20 km / h, to third gear at about 25 km / h and to fourth gear at about 35 km / h. It will most likely not be necessary to engage fifth gear;
- when downshifting, the engine speed must be increased to enable the next gear to be engaged. Release the accelerator pedal slightly and engage neutral, then apply the accelerator again while simultaneously moving the gearshift lever to the downshift position.
The gear should engage without any problems. When shifting to a lower gear, you should also reduce speed in order to control the gear shift. If there is a grinding noise in the gearbox, you should check again whether the gear is engaged. Thanks to the synchronizers, the gears should engage without any problems, although this will require some effort.
Possible clutch malfunctions, their causes and methods of elimination
| Cause of malfunction | Method of elimination | |
| Clutch jerking | ||
| 1. Defects in engine and gearbox mounts | 1. Check and replace if necessary | |
| 2. Loosening of the gearbox suspension mount | 2. Tighten the mounting bolts | |
| 3. Uneven pressure of the pressure plate | 3. Replace the pressure plate | |
| 4. Misalignment of the gearbox input shaft relative to the crankshaft | 4. Check the centering surfaces of the engine and gearbox | |
| Clutch slippage (clutch "slips") | ||
| 1. Excessive wear of the driven disk | 1. Replace the slave disk | |
| 2. Jamming of the working cylinder piston | 2. Replace the slave cylinder | |
| 3. The diaphragm springs have weakened | 3. Replace the pressure plate | |
| 4. Leakage in the working cylinder | 4. Conduct an external inspection | |
| 5. Hardening or oiling of the driven disk lining | 5. Replace the slave disk | |
| 6. The clutch was overheating | 6. Install the original clutch parts | |
| The gears do not engage or engage with difficulty (incomplete disengagement of the clutch - the clutch "leads") | ||
| 1. Jamming of the driven disk hub on the primary shaft (dry or dirty spline connection) | 1. Clean the splines, remove burrs, nicks, corrosion and re-lubricate the spline connection | |
| 2. Lateral runout of the driven disk | 2. Check the slave disk, straighten it or replace it | |
| 3. The clutch pedal does not reach the stop when pressed (increased free travel of clutch pedal) | 3. Adjust the clutch pedal free play | |
| 4. Air entering the hydraulic clutch system | 4. Remove air (bleed) from the hydraulic system | |
| 5. The driven disk parts are damaged | 5. Replace the slave disk | |
| Unusual noises when pressing the clutch pedal | ||
| 1. Defective release bearing | 1. Check and replace the release bearing | |
| 2. Runout of the driven disk on the pressure plate | 2. Replace the slave disk | |
| Increasing and decreasing noises during acceleration or engine braking or when coasting | ||
| 1. Weakening of the clutch riveted joints | 1. Replace the clutch | |
| 2. Large clutch imbalance | 2. Replace the drive and slave disks | |
