Eccentric
(DEALER ONLY)
Installation
1. Clean the BB shell and eccentric and apply a high quality bicycle bearing grease.
2. Apply Loctite 242 (blue) to the FIXING BOLT threads.
3. Slide the eccentric assembly into the drive side of the BB shell. Position the CENTERING BOLT
on the right (drive) side of the bicycle. It locates on the face of the bottom bracket shell to
center the assembly. It is not an adjustment; do not remove it.
Removal
Periodic removal, cleaning and renewal of grease will help ensure that the eccentric can be
rotated within the shell easily. This should only be done by a bike professional bike mechanic.
To remove the eccentric from the bottom bracket shell:
1. Loosening the fixing bolt. Turn it counter-clockwise enough to slide the complete eccentric
assembly out of the shell from the drive side.
NOTE:
Taping the head of the fixing bolt with a T-handle after it is loosened a turn or two. This
can free a stuck wedge. Forcing the bolt with a stuck wedge can damage the threads.
