Sheave Change/Adjustment

[@uscustomzauto]

As you open the sheave the fan speed slows. Closing the sheave or V groove makes the fan turn quicker, pushing the belt to the top of the V groove acting as a larger diameter pulley. Make sure your belt is within the right length for this pulley adjustment. You'll still need to set the final tension on the belt when you get the right sheave speed.

Finally someone that explains what I theorized was the purpose of the adjustable pulley... it's really to set the fan speed. However, that's all based on the HP of the motor, etc.

Thanks for your comment. I finally understand what is meant by increasing or decreasing the diameter of the pulley. Just from my user's manual it was not clear.

I learned something today. thank you my professor at YTU (KZbin University)

What does a sheave do for power? Torque? Nothing I imagine right it's just to fit larger belts?

You also need to make sure the pulleys are dead on parallel to each other.

[@SFlores1979]

at what point is the adjustable sheave considered fully open?

What happens when motor stops intermittently

Never pull off a belt with your hands, use a flathead

First! Turn Power Off
