I went to a machine shop today to get the bearing for my lower idler pulley pressed in and when I got home I realized they put the large disc portion on the wrong side, when I put the pulley back on it's on the backside and the bearing's exposed. Is that plate meant to keep the bearing held in there? Will I have to worry about it walking out after a while? It seems fine for now and it's pressed in so I'm not really worried about it popping out immediately but I do have to ask, it's gnawing at me. Thanks! :thankyou:
