This Awea BM-1600 spindle arrive to Northland Tool and Electronics completely seized. During disassembly, it was noted that the bearings were extremely difficult to remove. The bolts were loose/missing on the rear shaft cap and drawbar cap, both parts had cosmetic damage. The #2 bearing suffered a catastrophic failure and the cage was destroyed.
