Bottom bracket removal and installation
A conventional crankset is comprised of a left crankarm, right crankarm, and

2. Loosen the crankarm bolt on the right crankarm and remove the right
crankarm.
3. Using the proper tool, loosen and remove the left ("adjustable") bottom
bracket cup.
The left cup is right-hand threaded, and the right cup is left-hand (reverse) threaded.
3. Using the proper tool, loosen and remove the right ("fixed") bottom bracket
cup.
To install a Giga-Pipe bottom bracket
Make sure the frame's bottom bracket shell threads are clean and in good
condition. If necessary, chase and face the threads.
Grease all threaded surfaces, the bearing surfaces of the crank bolt, the
interfaces between the bearings and axle, the axle splines, and also the bearing
side of the seals.
1. Install the right bottom bracket cup, and tighten to 300-360 lb•in (34-41Nm).
2. Install the left bottom bracket cup, and tighten to 300-360 lb•in (34-41Nm).

If there is play, remove both crankarms, grease the contact between the bottom
bracket axle and the bearings, and reinstall. It may require installing the cranks
several times to eliminate all play.
