What should be paid attention to when replacing agricultural machinery accessories?

1. First of all, before replacing the new parts of agricultural machinery, the anti rust coating on the surface should be removed. At the same time, the accessories should be carefully checked for rust spots, cracks, deformation and other defects, so as to avoid potential accidents. In addition, it should be noted that the deformed products can not be used in common use. For example, some deformed products of the same model of diesel engine cannot be used in common use.

2. Secondly, in the replacement of agricultural machinery matching parts should be replaced in pairs. For example, when replacing the gear, the one with serious wear cannot be replaced; when replacing the cylinder liner, the piston and piston ring should be replaced at the same time. In addition, when replacing accessories, the standard parts and enlarged parts of the same model cannot be used. For example, the journal can only be equipped with standard curved bearing bush, otherwise the service life will be reduced.

3. Finally, when replacing the new parts, the model of the new parts and the old parts should be completely the same, and attention must be paid to the directionality during the installation, otherwise it is easy to cause looseness.
