397-8905 Hose Assembly — Cat Excavator 6020 6020B 6060

This is a high-pressure hydraulic hose assembly, designed to safely transport hydraulic fluid between components in the machine's system. Constructed with durable materials and reinforced layers, it ensures reliable fluid transfer under extreme operating conditions, unlike a worn or damaged hose that may leak or burst. Operators may notice hydraulic fluid leaks, a sudden loss of hydraulic function, or a 'whipping' hose if this assembly begins to fail.

Installation & Application Notes

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The initial symptom of a failing hydraulic hose assembly is often a small leak at the fitting or along the hose body, sometimes accompanied by a faint smell of hydraulic fluid. If ignored, the leak will worsen, potentially leading to a significant loss of hydraulic pressure and function, or a hose rupture. A burst hose can cause sudden loss of control over machine functions and create a significant safety hazard.

Installation Tip

Ensure all hose fittings are clean and properly aligned before tightening to prevent cross-threading or damage to the seals. Avoid twisting the hose during installation, as this can restrict flow and cause premature failure.

Service Note

Inspect all other hydraulic hoses, fittings, and the hydraulic fluid level when replacing a hose assembly.
