Exhaust Of Clutch Hydraulic System
Exhaust Of Clutch Hydraulic System
When there is air in the clutch hydraulic system, it can cause the clutch control system to operate abnormally. Therefore, it is necessary to exhaust.
The manual exhaust method is as follows:
A) First, fill the clutch oil reservoir with synthetic brake fluid.
B) Remove the dust cap of the clutch slave cylinder and loosen the bleed bolt of the slave cylinder.
C) Place one end of a plastic pipe with the same inner diameter as the exhaust nozzle of the bleed bolt on the bleed bolt, and insert the other end into a bottle containing brake fluid.
D) The assistant repeatedly steps on the clutch pedal and observes the bubbles discharging from the bottle until no bubbles are discharged. After the pedal force increases, tighten the bleed bolt and remove the plastic tube.
The exhaust method for the filling equipment is as follows:
A) Add the specified clutch oil to the filling device and inflate the device to (2-4) atmospheres, then prepare for operation.
B) Unscrew the plug of the oil discharge hole of the clutch slave cylinder, install the oil nozzle of the filling device onto the oil discharge hole, open the filling device, and start refueling from the slave cylinder until the clutch oil cup is filled to about 2/3 and there are no bubbles in the oil. Pay attention to opening the oil cup cover when filling.
C) After filling, step on the clutch pedal with strong force, indicating that there is no air present in the pipeline, which is qualified; If the pedal is weak, continue to exhaust (at this point, pour some oil out of the oil cup and continue to refuel with the equipment).
Precautions:
I. When tightening the vent bolt, do not use excessive force, and it is advisable to feel the force with your hands. Excessive torque can damage the sealing strip of the vent bolt, causing air leakage;
II When using a plastic tube to expel air, the nozzle inserted into the end of the brake fluid bottle should not expose the liquid level.
