PRESS FIT BOTTOM BRACKET BEARING TOOL SET 22/24MM PARK TOOL BBT-90.3

The Park Tool BBT-90.3 is the press fit bottom bracket bearing tool set designed to remove and install bearings and bearing cups in most press fit bottom brackets with a 22 or 24 mm spindle, such as Shimano press fit and SRAM GXP press fit systems, including the BB90 and BB92 standards.

The set combines two functions. The first is removal: the bearing remover passes through the bottom bracket shell and, with its fingers, grips the bearing from the opposite side to drive it out. The remover shaft has a nominal outer diameter of 22 mm, while the fingers reach 26 mm. The second is installation: the set includes bushings to be used with a cup press, such as the Park Tool HHP-2 or HHP-3 (sold separately), to press new bearings in straight and under control.

How the Park Tool BBT-90.3 press fit bearing tool set works

• Insert the remover into the bottom bracket shell until it reaches the bearing to be removed
• The remover fingers grip the inner edge of the bearing or cup
• Working on the end of the shaft drives the bearing out of the shell
• For reassembly, fit the bushings to the cup press and press the new bearings into place

Why choose the Park Tool BBT-90.3

Creaks, play or worn bearings in a press fit bottom bracket call for specific tools so as not to damage the frame seats. Before pressing in new bearings it is good practice to clean the shell seats carefully and check them for marks or burrs left by the old bearings, so the new installation will be precise and quiet. With the Park Tool BBT-90.3 press fit bottom bracket bearing tool set replacement becomes a tidy, repeatable job.
