Will extract bearings with 30mm internal and 42mm external diameters. BB30/BB30A 6806 <b>Hardware required</b> (Metric/Imperial) 100mm M12 (1/2") bolt 1x oversize washer, diameter 50mm 1x M12 (1/2") washer 1x M12 (1/2") nut <b>Tools required</b> 1x 19mm (3/4") socket and extension bar (through the BB shell) 1x 19mm (3/4") ring spanner <b>Note</b> If you don't have a socket then you can lock x2 additional nuts on the other end of the thread (see photo below) and use 2 spanners to wind the bearing out. Friends told me it wouldn't work and that the plastic would fail. They were 100% wrong. This thing exceeded my expectations. It is very very solid. My bearings were glued in with RED Loctite 263, this puller made mincemeat of the Loctite and the bearings pulled out first time giving little resistance. I printed with 5 walls, 100% infill and in Flashforge black PLA. If you prefer the professional look then print it in Park Tool blue
