4067833 Excavator Hydraulic oil tank pipe clamp for ZX450-3 

The Hitachi original excavator hydraulic oil tank pipe clamp (part number: 4067833) is a key structural component used to securely fix the hydraulic oil tank to the excavator frame or chassis. According to the general adaptation rules of Hitachi excavator accessories, this pipe clamp is usually suitable for hydraulic oil tank installation points of Hitachi ZAXIS series (such as ZX200, ZX240, ZX330, etc.) and EX series (such as EX200, EX300, etc.) medium to large excavators. As an original accessory, its installation hole spacing, curvature, and bolt specifications are precisely matched with the corresponding supports on the host frame, ensuring that the fuel tank has no displacement risk under severe equipment vibration and complex working conditions.

The hydraulic oil tank pipe clamp is usually made of high-strength structural steel (such as Q345 or similar materials) stamped or bent, and surface treated with galvanizing, Dacromet or spray coating, which has excellent corrosion resistance and fatigue strength. Its structural design is mostly in the form of "U-bolts+pressure plates" or "clamps+brackets", which are connected to the welded nuts or threaded holes on the frame through high-strength bolts (usually grade 8.8 or higher), tightly clamping the fuel tank body on the preset mounting seat.
 

The maintenance core of the fuel tank pipe clamp lies in regularly checking the fastening status, preventing rust, and coordinating with the standardized disassembly and assembly during fuel tank maintenance. Regular inspection: It is recommended to check whether the torque of all fixed bolts meets the standard (usually 40-60 N · m, please refer to the maintenance manual for details) every 250 working hours or during weekly maintenance, and use a torque wrench for verification; At the same time, visually inspect the clamp body for cracks, deformation, or severe corrosion, especially at the welding and bending points.
