My Clay Boss slows down when I'm pressing down to center clay.  The motor is 1/2 hp and the wheel is about 18 months old. I checked the belt and it wasn't at the center of the wheel belt pulley, so I adjusted it  following the instructions in the manual, and next time I threw it worked better for a few minutes then started slowing again.   When I checked it, the belt was off center again.  I sent a picture to Speedball and they decided I need a new wheel head/shaft and bearing, which they sent me.  Does this repair make sense?   Today is Saturday and Speedball is closed, but I'm not sure I want to switch out the wheel heads until I understand why it will make a difference.    Is the wheel supposed to maintain speed when you're centering or is the motor too small in this model?    

Thanks for any help or suggestions.

Is the wheel slowing because the belt is slipping or because the motor is slowing down under the load? Those are two separate issues. if the belt is slipping because it's not full seated on the bearing, then the new bearing should fix the problem. It could also be a belt tension issue. Is there a way to tighten the belt? Most wheels have a spring mechanism where the motor attaches, that can be adjusted to put more or less tension on the belt. But if the motor is bogging down, then it's under-powered. Is it happening only with larger amounts of clay?

The horsepower rating doesn't mean much. The 1/4hp Soldner can center as much as a Skutt 1/3hp, which can center as much as a Brent 1hp. The controller and pedal have a lot to do with how the power is put to use, as well as the type of motor.

I don't work with more than 3 lbs of clay, and usually between 1-2.   How can you tell if it's the motor is slowing down or the belt slipping?  I don't see a spring mechanism but you can adjust the motor back by moving the plate that holds it to the frame.  If the belt is uncentered,  does that mean it's slipping?   

 What would you suggest trying first?  Moving the motor would be easiest, but would it be better to change out the wheel head assembly in case the bearing is off?  Thanks!

Hmm, the manual says you can increase the belts tension by rotating the lock nut.  And now I remember that I did that when I first adjusted the belt and

 it didn't hold.  Maybe I didn't do it right.  I'm going to find the video instructions again

Often when the belt is slipping you can grab the wheel head and stop it from spinning. Be careful doing, that, though. You don't want to hurt your hands. Do it at somewhat slow speed. Also when it slips during centering it won't necessarily be an even slippage- it'll be a little jerky. If the belt isn't fully seated on the bearing, then there may not be enough friction for the belt to hold, and it'll slip.
