What is the reason for the heavy clutch?

The way to reduce the burden of heavy truck clutch is to adjust: 1. Adjust the push rod of the clutch auxiliary pump, which is located on the transmission side. The method is simple. Loosen the fixed nut of the rod first, and then turn the push rod (after the fixed nut is loosened, the push rod is movable and can rotate forward and backward). See if the rod becomes longer and shorter. Press the rod to make it return to the direction of the pressure plate. If there is a gap, it will be OK. If not, shorten the putter. 2. Adjust the clutch master cylinder. Under the clutch pedal, after using the method 1 and adjusting it properly, if the test run feels too high or too low, you can check whether the master cylinder is adjusted well first. 3. Similarly, the master cylinder is also a push rod. Just when the pedal is low, there is also a fixing nut. As long as it is loosened, the rod can be shortened or shortened. Generally, the master cylinder is loose and the clutch will be high.
