(1) Adjust the transposition method: This involves replacing worn components with ones that are less damaged or not worn at all, and then reassembling them in a different position to continue normal operation. This technique is especially useful for parts that have uneven wear and can still function if relocated. (2) Dimensional repair: Damaged parts are restored to their original specifications by modifying their geometric dimensions. For example, if the cylinder of a Dongfanghong 75(54) tractor becomes worn, its diameter can be increased by 0.25, 0.5, 0.75, 1.0, or 1.25 mm depending on the repair grade. Corresponding oversized pistons and piston rings are then used to maintain proper fit and performance. (3) Additional parts method: This approach involves attaching a special component to the worn area of a part in order to compensate for the loss due to wear. The added part helps restore the original fit and functionality, making it an effective solution for localized damage without needing to replace the entire component. (4) Replacement and partial replacement method: When a part is too damaged to be repaired economically or when repair costs exceed the value of the component, new parts are used as a replacement. In cases where only a portion of the part is damaged, the damaged section can be removed and replaced with a new one. The new piece is then welded or otherwise joined to the original base to form a complete, functional part. (5) Restoration size method: This technique involves bringing damaged parts back to their original technical specifications using various methods such as welding (electric, gas, or brazing), electroplating, spraying, rubber replenishment, forging, pressing, machining, heat treatment, and others. The choice of method depends on the material and the extent of damage. Repairing in this way is usually more cost-effective, with repair costs typically ranging from 5% to 50% of the original part's price. Important considerations during the repair process include ensuring that the shape and dimensions of the part remain accurate, maintaining surface hardness and wear resistance, avoiding changes to the metal matrix, and preventing the formation of harmful residual stresses. Additionally, the repaired part should not compromise future processing or performance after the repair is completed.
