During the build season this year, we had an issue with one of our IFI wheels on a 6 wheel drive train. The load on the aluminum side plate next to our sprocket was great enough to enlarge/deform the hole that the bearing sits in to 0.916". The outer diameter of the bearing is 0.875", which created a significant amount of wobble, which caused our chain to pop off once or twice, so we had to replace the wheel. The side plate opposite the sprocket was still intact. This happened on two separate occasions, first on the left front wheel, then the right rear wheel.
Has anyone else had issues like this? Any idea why it has happened to us?
