5. FAQ
Q1: Can this arm cylinder be mounted on PC240-8 model?
A: No, this 707-E1-00180 is customized exclusively for PC240-10/PC240LC-10, structural size differs from PC240-8 so cross installation is unavailable.
Q2: Does this cylinder come with complete seal kit together?
A: Yes, each finished cylinder is pre-installed with full set original-spec seals; spare replacement seal pack can be provided separately upon customer’s request.
Q3: How do you pack this big hydraulic cylinder for long-distance sea transport?
A: We adopt anti-rust oil coating + plastic wrapping + solid plywood case packing to avoid scratch and corrosion during ocean transit.
Q4: Is partial pre-payment available for bulk order of multiple cylinders?
A: We accept reasonable deposit term for large bulk purchase; flexible payment plan can be discussed via business negotiation.
Q5: What hydraulic oil type is recommended for this assembled cylinder?
A: Standard ISO VG46 anti-wear hydraulic oil matches best; inferior recycled hydraulic oil will shorten seal service lifespan.
