The Carrier P251-0074 Mounting Pack is a heavy-duty, OEM motor mount kit engineered for securing 42 and 48 frame direct-drive blower motors. This comprehensive hardware solution is critical for maintaining structural integrity and reducing vibrational harmonics in Carrier, Bryant, and Payne HVAC units. Constructed from stamped steel, the kit is designed to withstand the high torque and mechanical stresses of condenser and evaporator fan applications. By utilizing the included belly band, mounting arms, and isolation grommets, technicians can ensure precise alignment and a leveled base for 5.5-inch diameter motors with an 11.6-inch bolt circle configuration.

Professional installation of the P251-0074 mounting pack ensures consistent airflow and prevents premature bearing wear by isolating motor vibrations from the fan housing. The kit provides all necessary hardware, including 1/4-20 sleeved bolts and nuts, to facilitate a secure attachment. As a technician-grade component, it is optimized for high-demand environments where 15 to 27.5-ton rooftop units require specific motor mounting stability. This HVAC replacement part is essential for both maintenance and repair projects where original brackets have suffered from corrosion or metal fatigue.

Item is Non Cancelable / Non Returnable

Key Benefits

• Universal Compatibility: Engineered to fit standard 42 and 48 frame direct-drive motors, common in Carrier and Bryant rooftop units.
• Vibration Isolation: Includes high-grade rubber grommets to dampen mechanical noise and protect the assembly from structural stress.
• Rugged Construction: Stamped steel components provide a rigid, reliable mounting surface that resists deformation during high-torque startup.
• Complete Hardware Set: Comes with sleeved bolts and a belly band, eliminating the need for sourcing individual field-supplied fasteners.

Common Questions
