Questions about this item

Will the 5/8 in fixed bore on this BK5058 pulley fit the shaft on my existing motor?

The pulley has a 5/8 in fixed bore. Measure your motor shaft diameter; it must match 5/8 in exactly for a proper fit.

How can I verify the 4.75 in OD pulley is tracking correctly after installation?

Run the drive and check that the belt sits flush in the groove without wobble. Confirm the pulley rotates true and the belt shows even wear across its width.

Does the BK5058 come with a keyway, set screws or mounting hardware, or must I buy them separately?

The supplier data lists only the pulley with a 5/8 in fixed bore. Keyway, set screws and any mounting hardware are not included and must be sourced separately.
