Trouble, first lift the car, remove the right wheel, and then remove the side cover. I saw the crankshaft, and the entire crankshaft was wet. Use an air cannon to remove the crankshaft screw. After the screw is loosened and the oil is released, remove the belt. To remove the belt, just loosen the adjusting wheel nut, and then adjust the tire adjusting screw. Find the screw between the generator and the air conditioning pipe, and loosen it. The belt will be loose. Use a tool to loosen the screw. , the screw is loose and the belt is loose. After pulling it out, remove the screw with an air gun, and then pull out the crankshaft wheel directly. You can see that the crankshaft oil seal has been replaced and put back in place
The working principle of the air cannon:
During the operation of the pneumatic air cannon, its power comes from the air The compressed air output from the press enters the air cannon cylinder and drives the impeller inside to rotate to generate rotational power. At the same time, the impeller drives the connected striking parts to perform a hammering-like movement. After each strike, tighten the screws. Or remove it.
The more outstanding thing about the pneumatic air cannon is that the force it generates is usually proportional to the pressure of the air compressor, and exceeds the ability of two adults to tighten the bolts with a wrench more than two meters long. strength. This is equivalent to pneumatic air cannon being indispensable wherever there are disassembly and assembly of bolts.

Wind cannon application:
In order to remove car tires more quickly, the emergence of pneumatic air cannon is undoubtedly very powerful. This is an efficient and safe pneumatic tool for removing and installing screws. It is widely used in car tire disassembly and large mechanical organization and maintenance. According to the structure, there are generally single hammers with pins, double hammers with pins, three hammers with pins, four hammers with pins, double ring structures, and single hammers without pins.
High torque, light weight, no fatigue when used for a long time, and long life. Wind cannons are widely used in machinery manufacturing and maintenance, and are also suitable for various industries such as petrochemical industry, railway bridges, shipbuilding and power generation.
