XB00004817 Original Excavator Blower for Hitachi ZX68USR-5A

The part number XBU0004817 is an original blower assembly produced by Hitachi Construction Machinery China factory. This blower is suitable for models of the same tonnage as the cab air conditioning or ventilation system (such as the ZX small excavator series). Before purchasing, you must provide this part number (XBU0004817) along with the serial number of your device's body for final compatibility verification with Hitachi authorized dealers to avoid incorrect procurement due to model confusion.

This product is a turbine blower assembly, with a black engineering plastic volute as the core and multiple blade turbine impellers inside, driven by a DC motor. The impeller undergoes precise dynamic balancing correction to ensure smooth operation and low noise. The motor adopts a high torque design to overcome the resistance of the air conditioning filter and air duct. Its working voltage is usually 24V DC for vehicles, with a power of about 50-150W, and multiple air volume adjustments are achieved through speed regulating resistors or controllers. The shape of the air outlet of the snail shell perfectly matches the air duct inside the cab. Its function is to provide strong and stable airflow for the cabin air conditioning or heating system.

Installation specifications: 1 Power off: Before operation, be sure to disconnect the negative terminal of the battery. 2. Disassembly: Remove the relevant decorative panels inside the cab, disconnect the power harness and air duct of the old blower, and remove the fixing bolts. 3. Cleaning: Thoroughly clean the air duct inlet at the installation location to prevent debris from entering the fresh air fan. 4. Installation: Align the new blower (XB00004817) and connect the air duct. First, tighten all the fixing bolts by hand, and then use a torque wrench to evenly tighten them diagonally (usually 8-12 N · m). 5. Connection and testing: Connect the power harness, restore the battery, start the engine and test whether the air volume in each gear is normal and whether there is any abnormal noise.
