Sevcon Service & Repair Forum

: Our industrial unit is experiencing persistent issues with the hydraulic system in our production line. We have experienced multiple malfunctions, including incomplete processing of orders and production delays. The unit's hydraulic pressure control mechanism has been failing intermittently, causing significant disruptions to our workflow. While we believe a direct replacement for the existing hydraulic unit might be necessary, we need an assessment of the full scope of potential repairs and cost estimates for both repair options (full rebuild/replacement).:
