Belt Drives Ltd.

Upgrade to a TC and keep the early belt drive

Californian manufacturer Belt Drives Ltd. has developed a simple, easily installed steel insert which allows a newer Twin Cam engine to be run with a current or older belt drive system. This insert is internally broached to match the 24-spline sprocket shaft of the newer 2007-up Twin Cam engine. 

Once installed it will allow riders with an older BDL belt drive in an older style motorcycle the opportunity to upgrade the engine to a Twin Cam and still use the primary belt drive kit that is already installed. These inserts are available with offsets from zero to 2” in ¼” increments and are supplied with all new hardware to fit the new insert to a current offset front pulley.
The only additional part that is needed is a longer 9/16”-12 replacement for the bolt that holds the front pulley to the engine.
