    Excessive vibration normal w/ 7424?

    You know I was thinking about that. I saw that bolt in ony of the diy bearing replacement photos from the link posted above. But it wouldn't make sense to start taking things apart when the machine is less than 30 days old and I should be able to get it replaced. I'll keep you posted. Marty

    Excessive vibration normal w/ 7424?

    I took another look at the machine. I don't think the bearings are faulty because if I hold the housing (where the counterweight screws into) down, there is no play when shifting the nut (where the backing plate screws into).
