4735464 Original Excavator Shim Electric Ring for ZW310

Part number 4735464 is the original gasket electric ring (electrical connection sealing component) provided by Hitachi Construction Machinery for the ZW310 series 3-ton wheel loader. This component is mainly used for waterproof and dustproof sealing of electrical harness connectors, sensor interfaces, and other parts, ensuring reliable electrical connections and preventing short circuit corrosion. Its universal models cover ZW series wheel loaders such as Hitachi ZW310-5, ZW310-6, ZW330-6, as well as similar electrical interfaces for some ZX series excavators. As an original electrical seal, its size, material, and connector groove are precisely matched. It is strictly prohibited to use non-standard spare parts to avoid seal failure, water ingress short circuit, or signal interference.

This product is a combination gasket electric ring, usually composed of a conductive ring (copper or galvanized steel) and an insulating sealing gasket (nitrile rubber or silicone rubber). Typical technical parameters: working voltage ≤ 48V, working current ≤ 10A, protection grade IP67 (dustproof and waterproof), working temperature -40 ℃ to+120 ℃, oil resistance, ozone resistance and aging resistance. The thickness of the electric ring is 0.5-2.0mm, and the inner and outer diameters are customized according to the specific interface. Its conductive ring ensures reliable electrical conductivity, and the sealing gasket ensures 100% sealing at the interface to prevent water vapor and dust from entering.

Replacement timing: If the electrical interface becomes loose, leaks water, or undergoes preventive inspection and replacement every 6000 working hours. Replacement steps: 1 Disconnect the power supply; 2. Disassemble the connector; 3. Remove the old gasket electric ring (be careful not to damage the connector pins); 4. Clean the connector groove (with anhydrous alcohol); 5. Install a new gasket electric ring (ensure that the conductive surface is facing correctly and the sealing gasket is fully pressed into the groove); 6. Reconnect and lock the connector. Attention: 1 Before installation, check the gasket and electric ring for cracks and deformation; 2. It is strictly prohibited to apply lubricating grease to the sealing surface; 3. The locking torque of the connector must comply with the requirements of the maintenance manual
