Pinion Gear Chipped - is it ok to run?

I look at it this way. If it was new, then I expect perfect condition. I would expect money back including shipping. U can run them like that cause when the gears are rotating the load is shared but 2/3/4 teeth at the same time depending on the ratio. When hauling *** the crown gear wants to suck the pinion into it. Ok, I just went back to see the pattern, even though ur just showing the pinion I can tell u that the pinion is no where close to being right. Do not run them. Demand ur money back. Kim
