Prince accessories all with parts of the frame assembly has strict requirements, which do not meet the requirements, it will cause a malfunction. Piston and cylinder liner with the gap does not meet the requirements of the open position is not staggered piston ring installation, gas ring mounted inverted caused by human error. Prince accessories all with parts of the frame assembly has strict requirements for long cab, do not meet the requirements, it will cause a malfunction. Piston and cylinder liner with the gap does not meet the requirements of the open position is not staggered piston ring installation, gas ring mounted inverted caused by human error. Prince accessories main bearing and connecting rod bearing frame assembly position reversed or wrong change. With the gap and tightening torque does not meet the requirements, causing the piston oil leak and channeling phenomenon. Timing gears before positioning error cab, causing the piston and valve collision, oil time is incorrect, the combustion deterioration, lack of power, exhaust smoke, difficulty in starting, or simply can not start. Prince frame accessories valve clearance is too small, causing the valve closed lax, or accelerated wear and tear gas distribution parts. Injection timing is not correct, uneven oil interval angle of each cylinder and fuel supply, diesel engine operation is unstable, burn worse. Autumn morning dew more, Prince frame surface is often very humid, if your frame surface Prince obvious scratches, paint treatment should be done in time to avoid scratches and rust damp parts Additionally, due to the summer rain moderate acid corrosion and summer strong direct light, car paint will inevitably be oxidized in the season, the time to do your best from cleaning, polishing to waxing, sealing glaze or coating to the surface of your car a series beauty maintenance. In the hot summer, as some open heavy truck drivers who are hoping to use the air conditioning, with air conditioning and refrigeration than the open windows of the cab comfortable natural wind blowing. Especially if the weather is too hot in the summer will make people feel tired and sleepy so that will be very dangerous on the highway. If your cab with air conditioning is broken can not be used now can not worry about the cab, here I'll Prince cab for automotive air conditioning is not cooling the main reason for which: A: First, we must determine what our air conditioning and refrigeration agent for the adequacy or poor quality, as some drivers to drive for years have never checked the air conditioning refrigerant, the refrigerant is too small or if the quality is not good, it should be added or replaced good punch refrigerant. II: cab air conditioning room temperature sense head reaches the set temperature. Automotive air conditioning and indoor air-conditioned home is the same as if the car after the first air-conditioned room temperature reaches the set temperature, the air conditioning unit will no longer work, the main manifestations are: After conditioning reaches a certain temperature, enter shutdown. Three: compressor capacitor damage or bad. Automotive Compressor capacitor damage or bad, it will cause the compressor does not work. The main manifestations are: automotive interior and machines are working, the compressor does not rotate and can cause overheating. Four: Check the condenser is faulty. If we need a long time to clean the condenser, because over time, then the surface condenser will cover some of the dust is not conducive to the discharge of heat, we can use water to clean it. Five: Check the compressor belt. Compressed air conditioner in the summer, when the opportunity to try different sound issue, if we want to change the belt is loose pieces new, enough power compressor will work properly, air conditioning and refrigeration to work properly. These are my simple analysis of the Prince cab air conditioning failure, we want to help. Cab lights, cab, Jinan Yiu Cheung Yiu Cheung provided by Jinan Trading Company.
