Fox Transfer Actuator Fix

It seems like these snap or crack often and the replacements run $50. I designed this to salvage the broken part to create something stronger and objectively better then fox's design. It was tested on a 30.9 post but I imagine it should work on a wide range of dropper post sizes as you will use the threads from the original actuator to mount.

Instructions for assembly:

1. Remove old actuator from post (twist with pliers or vise counter-clockwize)
2. Remove 4mm pin from actuator body
3. Cut/Sand off any broken parts of actuator until top is flush
4. Print Model
5. Use model as a stencil to drill 4mm holes in old actuator body
6. Install hardware & assemble (see hardware list, photos)
7. Screw in new actuator body

Installation Hints

• Pins and nuts are tight fitting. Use a vice or parallel jaw pliers (Knipex pliers wrench) to get parts to go in straight.
• Don't over-tighten screws. Let the nylon nuts do their job. Loctite not required but recommended.
