4717120330 Loader Wear Ring for ZW310-6

Part number 4717120330 is an original wear-resistant ring specially designed by Hitachi for the ZW310-6 wheel loader. This component is a ring-shaped structure, usually installed at key hinge points of the equipment, such as steering hinge pins, working device connection pins, etc., as a wear-resistant pad between the pin shaft and the structural component hole. Its universal model is this part number, which is precisely adapted to the ZW310-6 model. As the core wear-resistant component of the original factory, its inner diameter, outer diameter, thickness, and the fit tolerance of the pin shaft and installation hole have been precisely calculated

This product is a wear-resistant ring injection molded from engineering plastic material (usually high-performance polyoxymethylene POM or nylon). The main body is a beige circular ring, and the outer wall is processed with uniform vertical stripes. This design can increase the contact stability with the installation hole, prevent rotation, and the groove can also store a small amount of lubricating grease. The material itself has an extremely low coefficient of friction, excellent self-lubricating properties, and wear resistance, which can effectively reduce direct friction and impact between the metal pin shaft and the structural component hole. Its core function is to provide reliable wear protection and extend the life of the hinge point even under conditions where lubricating grease is not frequently added.

Inspection and replacement cycle: It is recommended to check this wear-resistant ring every 1000 working hours or every six months of equipment operation during maintenance of relevant parts. Daily inspection: Focus on checking whether the ring body has uneven severe wear, fragmentation, deformation, or permanent crushing. Replacement operation: 1 Disassembly: Disassemble the corresponding pin shaft and remove the worn old wear-resistant ring. 2. Cleaning: Thoroughly clean the old ring residue, rust, and dirt inside the installation holes of the pin shaft and structural components. 3. Installation: Press the new wear-resistant ring (4717120330) smoothly into the installation hole to ensure proper installation. An appropriate amount of long-lasting lubricating grease can be applied to the ring groove and the surface of the pin shaft. 4. Assembly: Reinstall the pin shaft and tighten it.
