3G Axel BBW Owner's Manual
Although the bottom bracket comes pre-installed on all our bicycles it is
good to know how the general assembly of these components is in case
of encountering problems (see figure I). Below is a diagram showcasing a
one piece crank set, the parts involved will be slightly different on a three
piece set.

Installing Bottom Bracket
1. Feed left crank arm into hole in center of chainring.
2. Follow this with the plastic spacer and then the threaded race.
3. Grease the race and bearings, and feed the bearing onto the crank with
balls facing in
4. Grease cups. Insert left crank arm through right side of bike.
5. Grease next set of bearings and feed them to the left arm facing inward.
6. Feed the second threaded race (flat side facing out).
7. Finish with the washer and a lock nut. Make sure whole assembly is
tight but able to spin freely.
NOTE - The cups are the first parts to be installed into the
frame. The threaded races thread onto the threads indicated
on the crank itself. All pieces fit on via left crank arm (thinner
arm)
