6 Speed Transmission Rebuild

Harley-Davidson 6 Speed Rebuild
Run Time 83 Min

The Harley 6 Speed Rebuild Project is here! The Harley 6 Speed has been in service since 2006 when it was introduced to the Dyna family. Higher road speeds made this a necessity for Harley-Davidson. It has had it’s fair share of positive and negative reviews. Aftermarket companies jumped on its’ downfalls to make a better overdrive. This 83 Minute video project will show you how to rebuild your Harley 6 speed and it will provide you a great walk through if you plan to swap out for an aftermarket transmission.

The Harley 6 speed transmission is excellent, but they do have one week point. The transmission’s main drive gear bearing is a double roller bearing that is prone to premature failure.

Often, as early as 30 thousand miles, the hard-face of the bearing race(s) can wear away, eventually destroying the entire bearing. If you hear a whining sound, especially when coasting; it may be an indication of a failing main bearing. A leaking Harley 6 speed transmission can be another indication, as the main drive gear begins to tip and move out if position within the seal.
