After I got the machine running well, I found a bad drum bearing on the drive side. I got the bearing out last night. It has a part number on it, 6136. It is Japanese made. I found a bearing on the internet for $59! I also found one locally for $175. I am getting the local one because time is a factor it I am wondering why the huge price difference? Altec has the part for $380, locally its $175 and a bearing website has it at $59. Any input? I'm guess the cheapest one is of lower quality maybe?
