It is recommended to replace the clutch fluid every five years of vehicle operation.
We pump the hydraulic drive in the case when air got into the system for one reason or another. The presence of air in the hydraulic drive leads to incomplete disengagement of the clutch (clutch «leads») and, as a result, difficult gear shifting.
We carry out work together on a viewing ditch or a lift.
We clean the bleeder fitting of the clutch release cylinder from dirt, if necessary, add liquid to the reservoir. We remove the protective cap and put a rubber hose on the fitting head, the end of which is lowered into a container with a small amount of liquid. A transparent hose is convenient - bubbles of the removed air are clearly visible in it.
The assistant presses the clutch pedal 3-5 times at intervals of pressing 2-3 seconds and keeps the pedal depressed. Loosen the fitting 1/4-1/3 turn. Pedal «will leave» forward. When the outflow of liquid with air bubbles from the hose stops, we wrap the fitting, after which the assistant releases the pedal.
We repeat the indicated operation until air bubbles stop coming out of the system, monitoring the liquid level in the tank and topping it up as necessary.
When changing the fluid, we pump the system until fresh, lighter fluid comes out of the hose.
