FAQ


Q: What are the specific failure symptoms that indicate the 4467379 boom seal kit needs replacement?
A: Common indicators include the boom slowly dropping or "creeping" under load, visible hydraulic fluid streaks on the cylinder rod, or an external leak at the cylinder head. These issues suggest that the main piston seals or the rod wiper have lost their structural integrity.
 
Q: What are the professional technical requirements for installing this boom cylinder kit?
A: Prior to installation, inspect the cylinder rod for any deep scores or pitting. Use specialized hydraulic assembly tools to avoid pinching the new seals. All components must be lubricated with clean hydraulic oil, and the cylinder head must be torqued to the manufacturer’s specifications to prevent seal deformation.
 
Q: How do I ensure the 4467379 kit is the correct match for my specific equipment?
A: This kit is a direct cross-reference for OEM part number 4467379. It is optimized for ZX160, ZX180W, and ZX200 models. To guarantee fitment, confirm the cylinder bore and rod diameter against your machine's service manual, especially if your fleet has customized hydraulic configurations.
 
Q: How does this seal kit perform in extreme mining conditions or high-heat environments?
A: Our kit is engineered for stability in temperatures ranging from -35°C up to 110°C. The premium PTFE and TPU materials prevent seal hardening in cold climates and resist extrusion under the extreme thermal loads and high-pressure spikes common in heavy-duty mining and demolition sites.
 
Q: Can these seals withstand contaminated or high-viscosity hydraulic oil?
A: While clean oil is recommended, these seals are designed with superior chemical resistance and reinforced lips to handle the abrasive nature of slightly contaminated oil, providing a reliable safety margin in demanding industrial environments.
 

Q: What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
