RE: servo saver for Volcano Sv
You have to take the entire top plate off to get it out. The screw in the bottom does not remove. The saver slides over the screw. I just got done doing this last night.
Do you already have the replacement part? If not make sure you save the stock piece, you have to remove the "stud?" Not sure what to call it, it's the silver piece that is on the top of the servo saver arm, and put it in the new part. I ended up breaking mine so this is not an easy task, luckily I have a another truck to steal parts off of. If I'm wrong about the stud someone please let me know, I still need to find a replacement for the Alum parts that I have coming.
