Old Hallmark B-168 working fine but the blower makes a loud rackety sound when it slows down and looking for a pair of blower rubber bushings/cradle bearings for the repair. Any guidance on locating the bearings or input for the repair is appreciated.

    You have to slide the whole blower assembly out.

    As I recall there are only a couple of different size rubber enclosed bearings. Any HVAC supply house should have them. W W Grainger has them. Looks like Zoro has them on line

    If the shaft is bad then that should be replaced as well

    Find a source for the bearings and measure the shaft diameter. Have them available before you pull the blower out and return what you don't need.

    Google: WW Grainger and look for insert bearings. Click on the rubber enclosed ones they have a chart with all the sizes. Most of them the dimensions are close enough so they will probably all work if you get the shaft size right
