Adjustment transposition method

Swap the worn parts and continue working using the parts that are not worn or have less wear.

Repair dimension method

Repair the damaged parts to change their geometric dimensions, and equip them with corresponding modified accessories to achieve the specified fitting technical parameters. After the cylinder of the Dongfanghong-75 (54) tractor wears out, the diameter of the boring and grinding can be increased by 0.25, 0.5, according to the repair size O.75、 1.0 or 1.25 millimeters, equipped with corresponding enlarged pistons and piston rings.

Additional Parts Method

Assemble a special component onto the worn area of the component to compensate for its wear and restore its original mating relationship.

Replacement of parts and partial replacement method

When the parts are damaged to the point where they cannot be repaired or the repair cost is too high, new parts should be replaced; If various parts of the component are severely damaged locally, the damaged parts can be removed and a new part can be made. The new part can be connected to the original base part of the component through welding or other methods to restore its working ability.

Restoration size method

By welding (electric welding, gas welding, brazing), electroplating, spraying, adhesive repair, forging, pressing, turning, pliers, heat treatment and other methods, damaged parts can be restored to the external dimensions and performance specified in the technical requirements. When using this method, economic benefits should be considered, and the cost of repairing parts is generally about 5-50% of the original price.

Attention: Do not damage the shape and position accuracy of the parts; Cannot reduce the hardness and wear resistance of the surface of the parts; Cannot cause changes in the metal structure of the base metal of the parts or generate harmful residual forces, and cannot affect the processing of the repaired parts.

Insert Bearings：

Insert bearings (SKF Y-bearings) are based on sealed deep groove ball bearings in the 62 and 63 series, but have a convex outer ring and in most cases an extended inner ring with a specific locking device, enabling quick and easy mounting onto the shaft.
