Some agricultural machinery operators rely on personal experience to operate agricultural machinery. As everyone knows, some operations will not only help to use, but will damage agricultural machinery. For example:
First, cover the air filter with a silk cloth. In order to enhance the filter effect of its small drag, some robots cover the air filter with a silk cloth, which is believed to make the air cleaner. I wonder if the silk will hinder the smooth air flow into the cylinder and make the air supply to the cylinder insufficient. The combustion will be incomplete, resulting in black smoke and power drop.
Second, tighten the cylinder head cover screws with the adjustable wrench. The tightening force of the cylinder head nuts of various engines should be balanced. Use special sleeves and torque wrenches to evenly tighten the diagonals from the center to the edges. Some hand-operated wrenches are used as substitutes, which are easy to overpower and destabilize the nuts; and the screw tightening torque is uneven, which can easily cause the plane deformation of the cylinder head.
Third, cotton yarn wipe parts. When the diesel engine is overhauled, some operators will repeatedly scrub parts and the interior of the crankshaft with cotton yarn and diesel oil. This removes the oil, but burns the tiles for a short time. This is because a layer of cotton fiber is attached to the oil filter in the oil pan, which prevents the oil from entering the oil passage and causes burning of the tiles. Therefore, the cleaning part should use a brush.
