Just received my Maverick back from fx. They didn’t put the power wheel assembly back in the right spot. I meant to tell them where it was when I took it off (sent it disassembled) but forgot. However I would have expected the tech to tell it wasn’t right immediately like I did. Number 3 was clearly number 7 producing the hardest hammer hit. It was blatantly obvious. Anyway I digress, I went to change it and my dumb butt lost that little bearing behind the wheel. Ugh….I think it’s 3mm size? Does anyone know for sure before I order them from Amazon? Thank you much.
