- Quick-detachable bushing speeds belt changes
- Dual-groove design drives two belts simultaneously
- Compatible with A, B, AX, BX and 4L, 5L belt sections
- A-section pitch diameter 6.4 in for precise speed ratio
- B-section pitch diameter 6.8 in matches BX belt profile
Quick Detachable V-Belt Pulley
This Tb Wood'S 682B pulley accepts B and BX section V-belts on a 6.8 in pitch diameter and A or AX belts on a 6.4 in pitch diameter. It fits 4L and 5L light-duty belts as well. The two-groove design suits dual-belt drives in industrial machinery. Buyers needing a single-groove pulley or C-section belt compatibility should choose a different model.
Installation notes
The pulley mounts on a Quick Detachable bushing with a bore range from 1/2 in to 1-15/16 in. Correct bushing selection and torque are essential; an undersized bushing or loose fit will cause wobble and premature belt wear. Always verify shaft diameter before ordering the bushing.
Pitch diameter decides fit
The 6.8 in B/BX pitch diameter and 6.4 in A/AX pitch diameter determine whether the pulley matches your drive ratio. If your design requires a different pitch diameter or a third groove, this part will not work.

Questions about this item
How can I verify the 682B pulley is running true after installation?
Check for smooth rotation, no wobble at the 6.8 in B pitch diameter, and that belts sit evenly in both grooves without slipping or squealing.
What comes with the 682B and what must I source separately?
The pulley includes the 2-groove sheave for 4L, 5L, A, AX, B, BX belts; a Quick Detachable bushing and the V-belts themselves must be purchased separately.
Which belt trade sizes match the 6.4 in and 6.8 in pitch diameters on the 682B?
Use 4L, A or AX belts on the 6.4 in diameter and 5L, B or BX belts on the 6.8 in diameter; other listed sizes are not applicable.
