I bought a used ibc7 with a bit over 13,000 15 second cycles. The upper bearing was pretty gummed up and there was bearing dust (a rusty powdery substance) I have seen before when a bearing goes out blown through the engine compartment. looking at removing the socket? (the thing that receives the pitcher) shown in step 16. I think I need a vice with a 3/8 allen.
Also, I would recommend lubing the two bearings shown in step 16 now and again to increase the life of the blender. It would not require a full teardown. The rubber seals should pop open and a little cleaning and lube and all set. The bearings are 608rs which is a common available size.
