First, check the diesel engine in the oil tank of Low price micro digger price china. After opening the water tank cover, it was found that the antifreeze of Low price micro digger price china had a significant diesel engine smell, and the antifreeze of the car changed from dark red to light pink. This kind of situation confirmed that there was a diesel engine in the fuel tank of the car. Because of this situation, people first defined the common fault as the waterproof sleeve of the nozzle of the fuel injection pump of the car engine that correctly guided the diesel engine. The cold proof water path generates heat to the radiation source of the fuel injection pump, and the brake pipeline is located on the upper side of the waterproof sleeve of the nozzle. Therefore, when the sealing ring of the waterproof sleeve of the nozzle becomes brittle, the gasoline and diesel will enter the radiation source water path of the cylinder head, and the diesel will occur in the water storage tank.

First, open the engine valve cover of Low price micro digger price china, remove the fuel injection pump, and then press the heat pipe radiator to check whether the sealing ring of the nozzle sleeve is damaged. After inhibition, it was found that two mouth muffs were discharged from the vehicle antifreeze, which confirmed that the sealing ring was indeed damaged. Next, the sealing ring of the mouth sleeve must be gradually repaired and replaced. First, pull out your jacket. When pulling out the jacket, please use the professional special tools of jacket technology to pull out. The special tool is the tap buckle of the system software with three fourths of the nominal diameter of the thread (a sealing plug is installed at the bottom of the jacket jacket to prevent waste from entering the cylinder). When the buckle must be paid attention to, the net weight of the micro excavator and the tap do not have to shift, otherwise the cylinder head will be damaged. Pull out the jacket with three quarters of the extruder screw. It is not necessary to pull too fast to avoid rolling of the external thread of the collet.

After successfully pulling out the mouth sleeve, remove the iron pin and carbon deposits inside and the oil deposits in the hydraulic cylinder. After cleaning, install a new mouthpiece. During installation, the nozzle sleeve has different sealing properties, so pay attention to the displacement of the sealing ring during installation. After installing the seal ring, use common tools to install the seal ring. Before installing the mouth sleeve, please wipe salt free grease on the sealing ring of Low price micro digger price china as much as possible to prevent damage to the sealing ring. Install the mouth sleeve with a hammer.
