Questions about this item

What comes with the 2BK65 pulley and what must be purchased separately?

The pulley itself is supplied; a compatible Quick Detachable split-taper bushing and the appropriate 4L, 5L, A, AX, B or BX belts are sold separately.

How do I choose between the 5.5 in and 5.9 in pitch diameters on the 2BK65?

Use the 5.5 in diameter for 4L, 5L, A and AX belts and the 5.9 in diameter for B and BX belts to match the belt trade size.

What does the 5.5 in pitch diameter mean once the 2BK65 is installed?

It sets the effective driving diameter for A, AX, 4L and 5L belts, determining the speed ratio and belt engagement on the pulley.
