Butter is a lubricant often used in the maintenance of agricultural machinery, because it is sticky, and some agricultural machinery uses it as a binder, but it should be noted that the following places should not be used indiscriminately:
First, the piston ring: Some agricultural machinery in order to avoid dislocation of the piston ring during installation, in the ring groove greased the ring to stick, this is a great hazard. When the engine is working, the butter forms a jelly when it is hot, affecting the elasticity of the piston ring, reducing the sealing performance, and producing carbon deposition, which aggravates the wear of the machine parts.
Second, the cylinder head gasket: Some agricultural machinery when installing the cylinder, smear butter on both sides of the cylinder pad, that can increase the sealing degree of the cylinder, and the result is just the opposite. Because the cylinder temperature rises while the generator is working, the butter will quickly melt away and create voids that cause the cylinder to leak. At the same time, the melting of butter produces carbon deposits that accelerate deterioration of the cylinder pad.
Third, the governor: Some farm hand for easy installation, in the governor bracket with butter to stick the ball. In this way, the copper balls are not easy to separate under centrifugal force after starting. Once melted into the crankcase, the engine oil deteriorates and cannot be used.
