Reasons for heavy failure of the clutch pedal of TEREX spare parts

In the process of vehicle operation, various faults will occur, and the clutch part is no exception. When the clutch pedal is heavy and the driver is difficult to operate, it should be considered first that it may be caused by the fault of the clutch booster system.

The fault of clutch power system is mainly manifested in the following three aspects:

(1) The clutch button valve (control valve) is faulty.

(2) Some automobile clutch cables are improperly adjusted after installation or replacement. Due to the installation and adjustment problems, the installation plane height of the button valve cable contact point is greater than 35mm, resulting in insufficient cable pressure, the button valve rod can not be opened by moving down, the power cylinder does not air, and the clutch operation is very difficult. The distance should be readjusted and the air circuit of TEREX spare parts should be checked.

(3) The clutch cable steel wire is broken and jammed, which shows that the clutch pedal is heavy.

(4) Clutch booster cylinder failure. The main fault of clutch booster cylinder is air leakage. Although the piston is driven by gas, due to more air leakage, insufficient pressure and insufficient stroke of push rod. The booster cylinder is mainly composed of damaged seals and internal moisture and dirt.

(5) The four-circuit protection valve works poorly, the auxiliary air circuit pressure is too low or empty, the booster cylinder does not work or works poorly, and the clutch is heavy.

(6) The air pipe from the button valve to the booster cylinder leaks, the booster cylinder works poorly, and the TEREX spare part clutch is heavy.

In short, if there is a fault in the clutch booster system, first find the air circuit and check the seal of the button valve and the booster cylinder. Due to the serious oil leakage of the air compressor and the serious damage of the rubber parts in the valve, the air leakage of individual vehicles is caused. At this time, in addition to the maintenance of the valve, the air compressor should also be repaired to completely eliminate the fault.
