AstralPool - Motor Screw for Marathon Pool Pump - 4405010783

AstralPool – Motor Screw for Marathon Pool Pump

This is a genuine AstralPool replacement motor screw (part number 4405010783) designed to secure the motor assembly on AstralPool Marathon series pool pumps. As a small but critical fastener, it ensures the motor is held firmly in place for safe and vibration-free operation. Sourced directly from Fluidra, it meets the exact tolerances of the original factory fitment.

Compatibility

This motor screw is compatible with AstralPool Marathon pump models as listed in Fluidra exploded views 70716, 70717 (Marathon 1HP 230V 50Hz), and 70718 (Marathon 1.5HP 230V 50Hz). Always cross-reference your pump’s exploded view or model number before ordering to confirm fitment.

Why genuine matters

Using an original AstralPool screw ensures the correct thread specification, material grade, and corrosion resistance for a wet pool environment. Aftermarket fasteners with incorrect dimensions or inferior materials can strip threads, cause motor misalignment, or lead to premature pump failure — risks that a genuine OEM part eliminates.

Installation

Replacement is straightforward for a qualified pool technician: isolate power to the pump, remove the damaged or worn screw, and fit the new one to the manufacturer’s specified torque. It is recommended to inspect surrounding motor-mounting hardware at the same time to ensure the entire assembly is in good condition before returning the pump to service.
