4655056 Original Excavator Pipe Clip for ZX850-3 ZX890-5A ZX870-5G EX1200-6

Part number 4655056 is a Hitachi original pipe clamp, which is a key fixing component for hydraulic and pneumatic piping systems. According to Hitachi's parts system, this part number corresponds to the original metal pipe clamp, which is mainly used to fix hydraulic oil pipes, air pipes, wiring harnesses, etc. on excavators to prevent them from wearing, loosening, or falling off due to vibration. It is widely compatible with multiple hydraulic excavators in Hitachi ZX series and ZAXIS series, such as ZX200, ZX210, ZX240, ZX330, ZX450, etc. The specific compatibility needs to be determined according to the pipe diameter and installation position. The original part number is 4655056, which should be used as the reference for procurement. Due to differences in the diameter, fixing method, and installation bracket of different pipelines. Before replacement, it is necessary to provide clear photos of the complete model, pipeline position, and old pipe clamp of the excavator for accurate verification.
 

This pipe clamp is the core fastener that ensures the safe and reliable operation of the excavator pipeline system. Its core function is to firmly fix hydraulic hoses, steel pipes or wire harnesses on the frame or structural components, effectively limiting their displacement, reducing friction, fatigue and stress concentration caused by vibration and impact, thereby preventing pipeline rupture, loose joints or line wear. As an original component, it is usually made of high-strength galvanized steel or stainless steel stamping or casting, with a surface treated with rust prevention, and has excellent corrosion resistance, vibration resistance, and fatigue resistance. Its inner diameter, bandwidth, and locking structure (such as bolt hole spacing and buckle design) have been precisely designed to perfectly match the diameter of the pipeline and the installation bracket, ensuring even distribution of clamping force and preventing pipeline loosening without damaging the outer wall of the pipeline due to excessive tightness.
 

The maintenance core of this pipe clamp lies in regularly checking the fastening status, preventing rust, and timely replacing damaged parts. It is recommended to conduct a system check every 500 working hours or every quarter, and use appropriate tools to re tighten all the fixing bolts of the pipe clamps according to the original factory specified torque values to prevent loosening caused by vibration. Cleaning and rust prevention: Keep the pipe clamp and surrounding area clean, and promptly clean up accumulated soil, oil stains, and corrosive substances; When working in damp or saline alkali environments, regular application of rust proof grease can be used to extend its lifespan.
