To Install the Replacement Drive Train (DT)
1. Mark the orientation of the FL to DT before completing step 2 so that the four screws go back in the same holes in the DT for proper alignment.
2. Remove the four screws next to the 16-tooth bike sprocket and remove the FL.
3. Place a thin film of your HYDROBIKE chain lubricant in the inside of the FL to aid in the installation.
4. Place the DT through the frame from the left side of the bike.
5. Place the FL over the 16-tooth sprocket and push in from the right side.
6. Push on the FL with a “flat” tool (or handle of crescent wrench) and rotate the DT at the same time to fully seat the FL.
7. If it is too difficult to press the FL in, remove two inches of tape at a time (if too loose, add two inches) and repeat steps 4-7.
8. Use a small nail or bent paper clip to assure proper alignment of the holes before installing the screw. The DT should hold itself in any position needing only minimal force to rotate.
9. Install/tighten four screws until they slightly deform the FL.
