Needle Bearing Reset - Cannondale 2011 LEFTY 126564.PDF Owner's Manual

PBR/XLR Needle Bearing Reset
The following procedure should only be completed by a
professional bike mechanic.
To reset
1. Release all air pressure through Schrader valve in bottom
of fork.
2. PBR - Remove the outer collar with the Shimano tool TL-
FC32. Turn counter-clockwise.
XLR - Remove the outer collar with the Shimano tool
TL-FC32. Turn counter-clockwise. After the outer
collar is disconnected from the outer tube, lift the XLR
hydraulic assembly up and out of the damper. (During
Re-installation) Make sure the hex end of the XLR
assembly is properly aligned and enaged inside the
damper before the collar is threaded back on.
3. Compress the telescope and remove the two split rings
from the top cap.
4. Fully extend the fork, and measure from top edge of outer
tube to bottom edge of spindle. See right. If the length is
out of specification do the following:
Firmly extend the telescope until it stops (tip - listen for
the knocking at full extension to change from a hollow
sound to a solid sound - this indicates full extension has
been achieved). Do this several times using only moderate
force, extend the lower fork leg using a pumping action.
After, you have performed this action several times, re-
measure.
NOTICE
If fork is out of range following reset attempt, it may be
damaged internally. The fork should be disassembled
and inspected by a professional mechanic before it is
ridden.
TIP: If migration re-occurs frequently (immediately after
resetting), the cause could be damage present in the inner or
outer races, bearings/cages or other fork parts. Inspection
and replacement of damage parts will be required to correct
a persistent problem with bearing migration.
