Park Tool PT-BBT-147-12 bottom bracket puller
The BBT-147-12, precision-machined from 4140 steel, is a robust tool designed for the removal and installation of select 12-notch threaded bottom brackets, including Chris King® ThreadFit™ T47 and ThreadFit™ 30 models.
The BBT-147-12 is designed to be compatible with any bottom bracket with a corresponding tool interface, featuring an extra-deep body for extra-wide shells and low-profile walls at the engaging surfaces for recessed lockrings.
The BBT-147-12 has three tool engagement options – a 3/8„ drive socket, a 1“ hex socket, and 36mm flats for a wrench – allowing you to tackle even the most stubborn bottom bracket shells. For added stability, the BBT-147-12 features integrated threads for use with the Park Tool BBT-RS bottom bracket retention system or the GPS-1 guide pins.
It is suitable for 12-notch, larger diameter (outside of the teeth) 50–53mm, smaller diameter (inside of the teeth) 48.2mm threaded bottom bracket tool interfaces, including:
