2619337181 Original Loader Universal Joint for ZW250

Part number 2619337181 is the original universal joint provided by Hitachi for the ZW250 wheel loader. According to the Hitachi parts system rules, this component is usually also suitable for models in the ZW220, ZW310, ZW330 and other series. As a key connecting component of the transmission or steering system, it is used to transmit torque, compensate for axial and angular deviations, and ensure smooth power transmission. Its universal number (substitute part number) includes similar models such as 2619337180 and 2619337182, but the use of non-standard spare parts is strictly prohibited to avoid transmission failure or equipment damage.

This product is a Hitachi pure universal joint, forged and precision machined from high-strength alloy steel. The working angle can usually reach ± 15 ° -25 °, and the torque transmission capacity varies from 500 to 2000 N · m depending on the model. The protection level can reach IP54 or IP65, and it is suitable for high load, dusty, and humid working environments of loaders. Hitachi pure universal joints have significant advantages in wear resistance, fatigue resistance, and sealing: a service life of>5000 working hours, high-performance lubricating grease used internally, and dust-proof and waterproof design.

Replacement cycle: It is recommended to check every 3000-5000 working hours, or replace it in a timely manner based on fault manifestations such as abnormal noise, vibration, and decreased transmission efficiency. Daily inspection: Check the universal joint for looseness, abnormal noise, oil leakage, and whether the dust cover is damaged every week. Fault manifestation: Universal joint failure may cause abnormal noise, increased vibration, uneven power transmission, and heavy steering in the transmission system. Replacement steps: 1 Disconnect the negative terminal of the battery to ensure that the equipment is in a safe state; 2. Mark the relative position between the universal joint and the transmission shaft; 3. Disassemble the fixing bolts and remove the old universal joint; 4. Clean the installation surface and install the new universal joint in its original position; 5. Tighten the bolts to the standard torque and restore the connection; 6. Start the equipment and test whether the transmission system is smooth.
