Is there any way to effectively repair the crack along the seam of the plastic Nuovo Record pully wheels? I hate to throw them away as they are nearly new condition. I'm cleaning the rear derailleur and both idler wheels have the same identical crack along this seam.
The crack is about .75mm and I've noticed a bit more play and looseness. Does these cracked pully wheels pose a significant risk?
