AstralPool - Motor Tie Bolts for Columbia SS 3/4HP II Pump (Frame C.71) - 4405010016

AstralPool – Motor Tie Bolts for Columbia SS 3/4HP II Pump (Frame C.71)

These are the genuine AstralPool replacement motor tie bolts (through-bolts) for the C.71 IEC frame ATB motor fitted to the AstralPool Columbia SS 3/4HP II pump. Motor tie bolts are the long fasteners that clamp the motor’s end shields and stator housing together, maintaining the structural integrity of the motor assembly under continuous pool circulation loads.

Compatibilità

Designed specifically for the AstralPool Columbia SS 3/4HP II pump with ATB motor (parent SKU 32770). These tie bolts correspond to position 23 in the official Fluidra/AstralPool exploded view diagram for this pump model. Always cross-reference the exploded view diagram to confirm the correct part before ordering.

Perché l'originale conta

Genuine AstralPool tie bolts are manufactured to the exact thread pitch, length, and tensile specification of the original C.71 frame motor, ensuring the correct clamping load across the motor housing. Substituting non-genuine fasteners risks uneven clamping, vibration, premature bearing wear, and potential motor failure — particularly under the continuous duty cycles typical of pool filtration.

Installazione

Replacement of motor tie bolts requires the motor to be disconnected from mains power and removed from the pump. Fasteners should be replaced in matched sets and torqued evenly to the manufacturer’s specification. Professional installation by a qualified pool technician or electrician is strongly recommended.
