Quick Detachable Bushing Compatibility

This TB WOODS V-belt pulley accepts a quick detachable bushing for fast installation and removal. It suits power transmission drives that use 3V or 3VX belt sections. The three groove design supports multi belt arrangements. Buyers needing a fixed bore or a different belt profile cannot use this item.

Pitch Diameter And Belt Fit

The pulley provides a 3 inch pitch diameter for both 3V and 3VX belts. Other standard sections such as A B 4L 5L 5V and C are not applicable on this unit. Correct belt alignment depends on matching the groove profile to the belt cross section. Drives requiring a larger or smaller pitch diameter must select another part.

Bore Range Determines Shaft Fit

The quick detachable bushing covers a shaft range from 1/2 inch to 1-5/8 inch. This single dimension decides whether the pulley fits the driven equipment. Verify the exact shaft size before ordering. Applications outside this bore window will need a different bushing or pulley assembly.

Questions about this item

How do I install the 3V303 pulley on a shaft using the Quick Detachable bushing, and what step is commonly missed?

Mount the bushing on the shaft, slide the pulley over the bushing, insert the cap screws through the pulley flanges into the bushing, then tighten the screws evenly in a star pattern; the step often missed is rechecking screw torque after the first run-in period.

What maintenance will the 3V303 pulley and its Quick Detachable bushing need over time?

Periodically check the three V-grooves for sidewall wear and the bushing taper for fretting; retorque the cap screws if vibration appears, and replace the belt when groove depth exceeds the manufacturer limit.

What is the first limit that appears on the 3V303 pulley during sustained operation?

The 3-inch pitch diameter fixes the belt speed ratio, so the earliest limit is usually groove wear from continuous 3V or 3VX belt contact under load.
