Help with Masterflex pump for Calcium reactor

Piper27

I love bengals
So I finally figured out why my pump was clicking. The head doesn't fit the connection point where it attaches to the unit. The flat spot on the back of the head where the drive shaft connects together is smaller than the indention it fits into on the unit by a small amount therefore everytime it turns over it clicks because it's slipping back and forth in place. The number on the head doesn't match my units number either. I bought it used. The unit is a 7550-60.

So how do I find the right head or fix this one? Where do I order parts for this older unit?
I also want to order a new belt for it because it looks like it's dry and starting to crack. Is there a newer style head that will fit that is better?

Were you able to find a new belt for the 7550-60? My belt broke.
I believe i can get a replacement or close replacement, but manufacturer will look for Pitch, Tooth Shape, Profile of Pulleys, etc.

the belt states 130XL on it, it is a 4" diameter, but thats not enough to get an exact replacement

please let me know if you were able to source a belt and if so from where?
Thanks! -Greg
