Clutch booster cylinder damage caused by heavy pedal, but sometimes not necessarily the help cylinder itself causes. Because most of the power driven clutch booster comes from the gas cylinder of compressed air, compressed air to the booster if the pressure is too low, it will cause power shortage phenomenon occurred, so such failure should give priority to check the pressure of compressed air to the clutch booster.

Heavy pedal causes insufficient lubrication

The clutch of the truck is driven by a series of mechanical structures to drive the pressure plate to be separated by the Baotou heavy truck auxiliary cylinder (commonly known as the sub pump), and there are several points to be lubricated in this structure. If the lubrication is insufficient and the friction is too large, it will cause heavy clutch pedal of Baotou North heavy truck fittings.

For example, the clutch shifting fork shaft of some types of vehicles, because the lubricating point is inside the flywheel housing, can only be connected to the gearbox flywheel housing by a hose. But many times, when we add grease, we will ignore the existence of this lubrication point, causing the fork shaft friction is too large, causing heavy pedal, and even will eventually lead to fork too much load, fatigue fracture.

Heavy pedal separation, too tight bearing

Baotou beiben heavy truck parts clutch can realize the clutch function is accomplished by the pressure plate on the clutch pressing and relaxation, and the pressure plate pressing and relaxation, is accomplished by separating bearing fork drive. Separation of bearing sleeve in the gearbox input shaft on the cover of the guide sleeve before and after sliding to control the pressure plate separation, if the gap with the release bearing and the guide sleeve is too small, it will cause friction is too large, the driving force in the separation of waste bearing and the guide sleeve friction, pedal heavy also can hardly be avoided.
