I just purchased the Channel lock secure motor mount for the 6S Arrmas and cannot get my bearing to fit the opening. It is the same diameter but just too tight of of a tolerance. Anyone have trouble with fitment of the diff bearing with this mount? I have tried to place my diff 2-3 times and it always gets stuck before bottoming out. I have tried both sides of the diff to see if one bearing was off but it is the same either way. I also tried greasing the hole lightly and it still got stuck with ~1\3 to go. I mean stuck! I had to put the out drive on the floor and push down on the mount until it popped out. The same bearing goes into the stock mount easily. I don’t see any defects on the anodizing or anything... any help would be appreciated. I don’t know if it is a defect or if I will have this problem with any of them?
