Century Motors 1329A Length Adapter Kit

The Century Motors 1329A Length Adapter Kit is an essential field solution for technicians performing motor retrofits on 5-5/8 inch diameter motors (NEMA 48 Frame). This kit is specifically engineered to resolve alignment and spatial discrepancies when installing replacement motors that differ in physical length from the original equipment. By utilizing the Century 1329A adapter, contractors can securely mount motors into existing brackets—such as the 1218A length adapter bracket—without requiring extensive modification to the housing or mounting rails.

Built for durability and precision, the 1329A mounting kit includes two adapter plates, four adapter rings, and two resilient rings designed to dampen vibration and ensure a seated fit. The comprehensive hardware package, featuring twelve 8-32 nuts and twelve 10-32 nuts, allows for a robust mechanical connection in high-torque HVACR applications. This motor length extension kit is a standard requirement for maintaining proper belt tension or fan blade positioning when the replacement motor body is shorter than the technical specifications of the factory unit.

• Universal 48 Frame Compatibility: Precision-fit for all 5-5/8" diameter HVAC motors, ensuring a stable mounting surface across multiple brands.
• Complete Hardware Integration: Includes multiple nut sizes (8-32 and 10-32) and specialized resilient rings to eliminate field-sourcing delays.
• Vibration Dampening: The included rings provide necessary isolation, reducing audible noise and mechanical wear on the motor bearings and shaft.
• Standardized Fit: Simplifies the use of motors with different shaft lengths or body dimensions in restricted-space air handlers and condensers.

Will this kit work with any 5-5/8 inch motor?
Yes, the Century 1329A is designed as a universal mounting solution for 48 frame motors, regardless of the manufacturer, provided the motor diameter is 5-5/8 inches.

Does the kit include mounting brackets?
The 1329A contains the plates and rings necessary to adapt the motor length. It is frequently used in conjunction with the 1218A bracket for a complete mounting overhaul.

What is the primary function of the resilient rings in this kit?
The rings act as spacers and vibration isolators, ensuring the motor is positioned correctly within the mounting assembly while preventing metal-to-metal fatigue during operation.
