Farm Machinery Replacement Notes
Some operators believe that the replacement of agricultural machinery repair parts is very simple, the updated parts will be installed on the line. In actual fact, if the new parts are improperly assembled, the power of the agricultural machinery will decline, the fuel consumption will increase, and the start-up will be difficult; Therefore, the following points should be noted when buying and replacing new parts.
1. Pay attention to the quality of parts when buying new parts. Do not buy fake and inferior products, carefully inspect the parts for rust, cracks, deformation and other defects, and whether the surface size meets the requirements.
2. Before the assembly, the anti-rust coating on the surface of the new accessories should be cleaned. In particular, precision parts should be noticed to avoid potential accidents.
3, some fittings should be replaced in pairs. If you replace the gear, you can't replace only the one with more serious wear. When you replace the double-row sleeve roller chain in the gear box, you also need to replace the main and driven sprocket in pairs. When replacing the cylinder sleeve, you should replace the piston at the same time. Piston rings.
4, the same model standard parts and increase parts are not universal. Manufacturers will produce oversized parts for the user to repair. Therefore, when purchasing accessories, you must determine whether the purchased parts are standard parts or enlarged parts. For example, the journal can only be equipped with a standard crankshaft. Otherwise, the amount of machining when the shaft is scraped is very large. This wastes time and does not guarantee the quality of repairs. It also greatly reduces the service life of the parts.
5, when changing the new accessories, the new and old models should be exactly the same. When some pilots replaced the new nozzles, they did not pay attention to the specifications of the original injectors. They bought the needle valve parts incorrectly, which often caused difficulties in starting and re-inserted the nozzles.
6, must pay attention to the direction of the installation. Some parts have directionality. If they are installed incorrectly, they will cause difficulties or even damage the parts.
