Well if any of you remember a few weeks ago I bought some Acer Racing cermaic nitride bearings for my clutchbell on my new Sirio .21. Well they failed after 2 quarts and this caused my clutch to melt as the cltucbell could not spin idependently of the flywheel.
Not so clear picture but you can see the damage on the inner ring. Its is crushed on the inside and that bearing still has some good movement. The one on the outside looks fine but has major drag like some of the balls have broken inside the bearing case. I paid 8$ per bearing so its not the end of the world at $16 bucks but I tell you I dont think I want the $160 kit for my buggy now. Lets see how Acer's customer support is. I will update after I contact them.
By the way I did use the correct size and placement of the 2 washers. the thin one on the outside of the flywheel nut and the thick one on the outside of the clutchbell before you screw the end bolt in.
Here is the email I just sent @ 10:18am PAC time. They claim on their website to have very quick email response time so lets see.
My letter:
I bought two cermaic nitride clutchbell bearings for my Storm Pro as I just bought a Sirio .21 and wanted some top notch bearings for my top notch engine. The bearings lasted 2 quarts and then they froze the clutchbell so it would not move independly of the flywheel. I installed it correctly with the correct size and placement of the 2 washers. I am wondering how come this happened? Dont these bearings last longer than that? I was so impressed when I installed them as the would spin forever with the slightest spin in my fingers. Here is a picture of the inside bearing where the casing seems to be smashed. Its not clear I know but I think the damage is decipherable. The front bearing appears to have no damage cosmestically but it will not spin more than 180 degrees without stopping.
I was planning on buying the whole set for my Storm so I am really hoping you can shed light on what happened and why. Thanks for your help in advance.
