Adjustable Steel Motor Base

The Dayton 3M280 is an adjustable steel motor base designed for NEMA 184 frame motors. It provides a secure mounting platform for blower applications in HVAC and industrial settings. The black finished steel construction offers durability for continuous operation. This base suits maintenance technicians and facility managers replacing or aligning motor drives.

Capacity and Headroom

The base accommodates NEMA 184 frame motors with a single adjusting bolt for belt tension control. Overall dimensions are 12 3/4 inches in length, 10 1/2 inches in width, and 1 1/2 inches in height. It handles standard motor weights within this frame size but is not suited for larger NEMA frames or multi-bolt adjustment requirements. Builders needing multiple adjusting bolts or different frame compatibility must select an alternative base.

Build Quality and Mounting

Heavy-gauge steel construction resists vibration and corrosion in demanding environments. The single adjusting bolt allows straightforward belt tensioning during installation and routine maintenance. Mounting slots accept standard hardware for secure attachment to flat surfaces. The compact height profile fits tight mechanical rooms where space is limited. Installers requiring tool-free adjustment or sliding rail designs will find this fixed-bolt configuration less convenient.

Questions about this item

Will the 184 frame motor base fit the existing mounting pattern on my older blower housing?

The base is built for NEMA frame 184 and measures 12 3/4 in long by 10 1/2 in wide, so compare those centres to your current bolt pattern before ordering.

How can I verify the base is correctly aligned after I bolt it down?

With the single adjusting bolt centred, the motor shaft should sit level at the 1 1/2 in overall height; a straight-edge across the feet confirms even contact.

Does the 3M280 package include the mounting bolts and washers, or must I supply them?

The supplied hardware is the single adjusting bolt; mounting bolts, nuts and washers for the base-to-floor connection are not included and must be purchased separately.
