Description
Astralpool motor screw set 3/4 to 1.25 HP 4405010428
The Astralpool motor screw set 3/4 to 1.25 HP 4405010428 is an original fastening kit designed to secure the motor end bells and mounting
points on selected Astralpool pool pumps. With the correct length, thread and head type, these screws help keep the motor and hydraulic
body firmly assembled, ensuring quiet, reliable filtration in everyday use.
Original fastening kit for 0.75 to 1.25 HP motors
This screw set is specifically dimensioned for Astralpool motors in the 0.75, 1 and 1.25 horsepower range. It replaces worn, corroded or
mismatched screws that can no longer hold the motor parts securely, restoring the original clamping force and alignment. Using the
correct hardware is essential to prevent vibration, noise and unwanted movement during pump operation.
Secure fixation of motor housing and flanges
The Astralpool motor screw set 3/4 to 1.25 HP 4405010428 is used to fasten the rear cover, front flange and other motor components to
the stator body. Correctly tightened, these screws keep the bearings, rotor and shaft in their designed positions so the motor can drive
the impeller smoothly and efficiently.
- Maintains rigid connection between motor body, front flange and rear cover.
- Helps preserve accurate shaft alignment for smooth rotation.
- Supports long term bearing life by limiting unwanted movement.
Protection against corrosion and wear
Pool technical rooms are often humid environments with splashes and condensation. Over time, standard screws can corrode or seize, which
makes maintenance difficult and may reduce clamping strength. The Astralpool motor screw set 3/4 to 1.25 HP 4405010428 provides fresh,
clean fasteners that are suitable for this environment and can be removed again during future servicing.
- Replaces rusty or damaged screws that are difficult to tighten or loosen.
- Reduces the risk of broken heads during disassembly.
- Helps keep the motor enclosure closed and stable over many seasons.
Ideal for motor overhaul and refurbishment
Whenever a motor is opened for bearing replacement, cleaning or repainting, renewing the screws is good practice. Installing the
Astralpool motor screw set 3/4 to 1.25 HP 4405010428 during an overhaul ensures that old, weakened fasteners do not compromise the
quality of the work and that the motor can be reassembled to the same standard as a new unit.
- Recommended during bearing replacement or full motor service.
- Useful when converting an older pump to a new motor of the same frame size.
- Helps restore factory level assembly quality on refurbished pumps.
Installation and good practice
Fitting the Astralpool motor screw set 3/4 to 1.25 HP 4405010428 should always be done with the pump isolated electrically and
hydraulically. Correct tightening sequence and torque help protect the motor housing and ensure uniform clamping.
- Switch off the power and disconnect the pump before working on the motor.
- Remove old screws and clean the contact areas on the motor flanges and end bells.
- Start new screws by hand in their original locations to avoid cross threading.
- Tighten gradually in a cross pattern so the covers pull down evenly.
- Avoid overtightening, which can distort the housing or strip threads.
After reassembly, the shaft should turn freely and quietly by hand before the pump is reinstalled and restarted in the filtration
circuit.
