Dayton 6L105 Shaft Arbor for Motor Buffing

This Dayton 6L105 shaft arbor fits a 5/8 inch shaft and mounts buffing or finishing wheels on electric motors. It uses a 1/2-20 RH thread with a socket setscrew and includes a hex nut and machined washers for secure attachment.

Threaded Arbor with Counter-Clockwise Rotation

The 1 13/16 inch thread length and 1 1/2 inch washer outside diameter provide stable mounting for wheels up to 1 1/4 inch wide. Counter-clockwise shaft rotation matches standard motor output for consistent finishing work.

Replaces Worn or Missing Motor Arbors

This standard arbor replaces damaged or lost shafts on compatible Dayton keyless chucks. The jump is worth it when the original arbor threads are stripped or the setscrew no longer holds the wheel true.

Questions about this item

How do I install the Dayton 6L105 shaft arbor onto a 5/8 in motor shaft, and what step is often missed?

Slide the arbor onto the shaft, position the machined washers on each side of the wheel, thread the 1/2-20 RH hex nut, then tighten the socket setscrew against the shaft flat; skipping the setscrew lets the arbor spin loose.

What maintenance or replacement will the Dayton 6L105 shaft arbor need over time?

Inspect the socket setscrew and 1/2-20 RH thread for wear or rounding; replace the hex nut, machined washers, or the entire arbor if the setscrew no longer locks securely.

What limit appears first when running the Dayton 6L105 shaft arbor continuously with a wide wheel?

The 1 1/4 in maximum wheel width is the first constraint; exceeding it prevents proper washer clamping and risks wheel slippage during sustained operation.
