Clutch failure in what today by the China National Heavy Duty Truck Co., Ltd. craftsmen to tell:
models of heavy china truck engines idle when the clutch pedal Although foot in the end, but the gear difficulties, change gear percussion. Barely hung up the file, not yet relax the clutch pedal, the car has been exercised or flame.
first step is to check, according to the following steps:
to remove the the clutch case back, hang the transmission into neutral, step on the clutch in the end. Then, struck with screwdriver driven plate. If you can easily wheeled his clutch release; if the dial does not move, the clutch is not complete.
Then we again follow the steps to troubleshoot:
1,If the above adjustments to normal, still separated is not complete, it is necessary to remove the clutch, check the driven plate is installed backwards, the axial movement difficult without warping the main driven plate separation lever screw is loose, floating pin is off.
2, the hydraulic clutch friction plate, to check whether the driven plate and friction plate is too thick. If it is too thick, and the shims between the clutch cover and the flywheel.
3, clutch hydraulic transmission, in addition to the above checks, you should also check the brake fluid are you missing, pipeline leaks and exhaust air in the hydraulic system
4, check the clutch pedal free travel is too big, and adjust.
Check the separation lever height are the same, whether it is too low.
Separation fork under a car struck the front end of the release bearing lightly against the separation lever end face of rotating clutch for viewing a week, not on the inner end of the separation lever and release bearing contact, indicating that the separation lever a high degree of inconsistency, should be adjusted.
separation leverage highly consistent, still not completely separated, it is necessary to check the lever height. Each separate lever adjusted to the same height, and if they can be completely separated, the original improperly adjusted or worn too much. The separation lever adjustment must re-adjust the clutch pedal free travel.
