Hi, everyone, I joined the club a few weeks ago and have been really enjoying the game. Thanks for all of the helpful posts in this thread!
I had an issue where the spinning disc became loose on the rod, so the plastic disc was wobbly and didn’t always turn the rod when it spun. In order to fix this I removed the disc assembly (using the steps described in Stern’s “Avengers IQ Premium/LE Disc Leveling Bushing” instructions: https://o.pinside.com/f/f6/22/ff622811a56579c315112da0ea11441c518ca2a5.pdf), took the disc apart, and tightened the screw holding the disc to the rod (#8 in the diagram).
After this fix, the disc is nice and tight on the rod (with no wobble), but I noticed that solid hits to the disc no longer resulted in many spins. Instead, the ball hitting the disc makes a sort of buzzing sound, and this vibration seems to suck away all of the energy of the shot. See video below:
You can see that the disc (usually) spins freely when I spin it by hand, but this vibration/buzzing seems to cause the disc to not spin well when actually hit by the ball. I also get this buzzing when spinning the disc in the “UP” position, so it is not interference between the disc and ring/playfield. Has anyone seen this before? Any ideas for things to check? Are there things that I might have done wrong in removing/disassembling the disk?
I’m not very mechanically inclined, so please feel free to recommend obvious things to check! Thanks in advance! AEEE4B34-138C-4BCB-9DE2-AB631CB18409 (resized).jpeg
