Using a cotterless extractor and an impact driver, I removed the left and right cranks, removed the tightening bolt that doubles as the stand, and the tightening ring on the left crank side. I then hit the eccentric BB from the left side with a plastic hammer and it came off easily, so I installed the eccentric BB for the GTRO that I had made previously, then installed the GTRO main body and left crank, hung the belt, used the long bolt as leverage to adjust the tension, tightened the tightening ring, and then installed the stand.
Maybe because I changed the BB, the stand doesn’t end up in an extreme position even when the tension is just right, so I probably won’t need the 120mm belt I ordered and haven’t received yet (from Germany).
The reaction lever, which is the arm that secures the GTRO body to prevent it from rotating, was installed in the same position as it arrived, and it didn’t get in the adjustment slot of the BB fixing bolt.
The anti-scratch rubber seems to be working well, so maybe it’s fine?
