This is a classic sign of internal bypass or wear within the 708-1U-00280 pump. When the internal pistons or valve plates wear down, the pump cannot maintain the flow required for the GD705-5's heavy work cycles. Replacing the pump restores original cycle times.
Cavitation or bearing failure are common culprits. Ensure your hydraulic filters are clean. If the noise persists, the 7081U00280 pump likely has mechanical damage and should be inspected immediately to prevent metal shavings from contaminating the entire hydraulic circuit.
Our units feature an OEM-standard tri-metal structure on critical wear surfaces, ensuring longevity even in dusty or high-heat environments. We are trusted by repair shops and equipment fleets globally for providing reliable alternatives to expensive dealer parts.
