1. Insert SS495A1 into its socket in the top part of the lever frame (use a drop of super glue to fix it there) and solder its wires. Route wires as shown on the 3rd picture, use some glue as necessary.

2. Cut off a piece of 10mm square aluminum profile. Choose the length depending on the lever you want to build (as stated in the lever body manual, e.g. 200mm for a single throttle lever)

3. Put the lever connector part onto the rail.

4. Drill a 3mm hole through the rail and insert an M3x20mm screw with a nyloc nut.

5. Drill a 6mm hole for the axis through the rail with a 5,5mm drill.

6. We will be assembling the lever axis. Start with putting an M6x8x18mm hub onto an M6x70mm bolt.

7. Put 3 M8 washers onto the hub

8. Put 2 bearings onto the hub

9. Put a reinforced M6 nut onto the bolt

10. Put an axis though the lever connector part

11. Put a reinforced nut onto the M6 bolt.

12. Put another hub onto the bolt.

13. Put 2 bearings onto the hub

14. Add 3 M8 washers

15. Put an M6 washer and a nut onto the bolt. Use thread locker to fix the nut.

16. Put the magnet onto the nut and fix it with hot glue.

17. Insert the axis assembly into its frame.

18. Insert 4 M4x40mm bolts into the frame as shown in the picture below, put nuts from the other side, use thread locker.

19. Insert 4 M4x70mm screws into the frame as shown in the picture below, add nuts, use thread locker.

20. Put the curtain part on and fix it with 2 M4x40mm screws, add nuts, use thread locker. The axis assembly is finished!

21. Insert axis assembly into the housing. Fix with nuts, use thread locker.

22. Put the friction tensioner together. To do it, widen holes in its left part with a PH0 3mm screwdriver or a drill, and insert 4 M3x50mm screws into it. After that, connect the right part of the tensioner and put nyloc nuts on. Do not tighten too much.

23. Attach the tensioner to the lever housing. Add and tighten 4 M4 nuts so there will be some clearance between them and the tensioner.

24. Remove 2 pins (A2,A3) from the header. Only remove A3 if you will be making a twin lever.
