Motor Shaft Arbor for Small Motors
The Dayton 3ZN13 AL-5-L arbor mounts buffing and finishing wheels onto electric motors with a 5/8 inch shaft. It is built for smaller fractional horsepower units and includes a machined washer and hex nut for secure attachment. The heavy-duty construction suits workshop tasks that require a reliable wheel-holding interface.
Fits 5/8 Inch Shafts Only
This arbor suits mechanics and maintenance staff who need to fit wheels to a 5/8 inch motor shaft with a 1/2-20 left-hand thread. It will not work for builders who need a different shaft diameter, thread pitch or rotation direction. Buyers with larger industrial motors should look at a different arbor.
Thread Length 2 1/4 Inches
The 2 1/4 inch thread length and 1 1/2 inch washer diameter handle wheels up to 1 11/16 inch wide. Overall length reaches 6 1/4 inches, giving enough engagement for standard buffing jobs. Wider wheels or longer shaft extensions exceed the available thread and washer capacity.

Questions about this item
What shaft diameter must my motor have for the 5/8 in arbor to fit?
The arbor fits a 5/8 in motor shaft, so the motor shaft must measure exactly 5/8 in.
Will the 1/2 in.-20 LH thread engage the same nuts used on standard right-hand spindles?
No, the thread is left-hand, so it only works with matching left-hand nuts; standard right-hand nuts will not engage.
How can I confirm the setscrew is holding the wheel securely after installation?
Tighten the socket setscrew against the flat of the shaft, then try to rotate the wheel by hand — it should not move.
