Technical Information
Bottom Bracket (BB) - PF30A / 83 mm
Bottom Bracket (BB) - PF30A / 83 mm
Maintenance
Have the bearings inspected annually, anytime the the
crankset is removed, or if a problem is indicated. With
crankset removed, rotate the inner bearing race of both
bearings; rotation should be smooth and quiet.
Execessive play, roughness, or corrosion indicates a
damaged bearing.
Replacement
Bearings are not removable from the PF30 cup systems
pressed into the bottom bracket shell. Therefore, both
bearing and cup must be removed and together
replaced as a new set.
Before installing any new bearing units into the shell,
thoroughly clean the inside surface of the bottom
bracket shell with a clean, dry shop towel. Also, make
sure both bearing units and the BB shell surfaces are
clean and dry. Do not apply grease.
Follow the manufacturer’s instruction for assembly
and installation of the bearing system using a
headset press such as a Park Tool HHP-2.
Select the appropriate press and adapters to ensure
that force is only applied to the cup and not to the
bearing inside. Press until both cup flanges are
mated to the BB shell edge.
