Will extract bearings with 30mm internal and 42mm external diameters. BB30/BB30A 6806
Hardware required (Metric/Imperial)
100mm M12 (1/2") bolt
1x oversize washer, diameter 50mm
1x M12 (1/2") washer
1x M12 (1/2") nut
Tools required
1x 19mm (3/4") socket and extension bar (through the BB shell)
1x 19mm (3/4") ring spanner
If you don't have a socket then you can lock x2 additional nuts on the other end of the thread (see photo) and use 2 spanners to wind the bearing out.
Notes
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
