EE106 BB-PF30 Bearing Alignment Gauge
The gauge is used to check that the surface where
the PF30 bearing cups press in are in alignment
with each other. If the PF30 bearings are not able
to be installed in alignment with each other, the
bearings may bind and prematurely fail after
crankset installation.
Inspection
1.
Check BB shell and remove any excess paint,
metal chips, dirt or debris.
2.
Insert shaft with handle into right or left BB shell
opening. Slide the opposing side of the gauge
onto the shaft moving each inspection surface
into the right and left openings of the BB shell.
3.
Gently press the gauge into the BB shell until it
is completely inserted.
The gauge will fit tightly into the BB shell. Do not
use a hammer or any pounding motion to insert the
gauge into the frame!
If the BB shell is not in alignment it will be
impossible to install the alignment gauge.
Note: The tolerance of BB shell eccentric is
±
0.02mm.
