Dayton 3M367 U-Frame Adapt-O-Mount 284U-286U to 254T-256T
Adapt-O-Mount converts NEMA 284U and 286U frames to 254T and 256T frames while preserving shaft alignment
- Converts NEMA 284U and 286U motors to fit 254T and 256T frames
- Maintains original motor centreline and shaft extension without modification
- Corrosion-resistant grey primer finish protects against rust in harsh environments
- Pre-welded nuts and zinc-plated bolts simplify installation and save time
- Compact 14 1/2 in length fits tight mounting spaces
Motor-Mount Adapter
The Dayton 3M367 U-Frame Adapt-O-Mount converts NEMA U-frame motors 284U and 286U to fit NEMA T-frame footprints 254T and 256T. It compensates for mounting-hole and shaft-height differences without shifting the motor axial centreline or shaft extension. The adapter measures 14 1/2 in long, 2 1/2 in wide and 3/4 in high with a corrosion-resistant grey primer finish.
Frame-Size Conversion
The single specification that determines fit is the frame-size mapping: 284U and 286U motors to 254T and 256T bolt patterns. Nuts are welded to the base and zinc-plated bolts are supplied for direct installation. No other frame sizes or motor series are addressed by this adapter.
Installation Context
The adapter bolts between the motor feet and the existing T-frame mounting surface, bridging the hole-pattern offset while preserving shaft alignment. It requires no machining of the motor or driven equipment. Builders needing to adapt other U-frame sizes or different T-frame patterns must use a different conversion kit.

Questions about this item
Will the 3/4 inch height of the 3M367 adapter keep my motor shaft centreline exactly where it was?
Yes, the U-Frame Adapt-O-Mount compensates for mounting-hole and shaft-height differences without altering the motor axial centreline or end-of-shaft extension.
Does the 3M367 mount use the standard NEMA bolt pattern for 284U and 286U frames?
It converts NEMA U frames 284U and 286U to NEMA T frames 254T and 256T, with nuts welded onto the base and zinc-plated bolts supplied.
How much floor space does the 14 1/2 inch long adapter need for installation?
The mount measures 14 1/2 inches long by 2 1/2 inches wide, so allow at least that footprint plus bolt clearance.
