Title: Torsion bar adjustment
Post by: janjon on May 07, 2021, 02:07:04 PM

Hello, does anyone have any pics or drawings of the inner workings of the VW torsion tube assembly commonly used on FEDs,
and any suggestions on how best to lock out all travel ?

The part of the VW torsion bar that provides movement is a stack of 1 inch-ish by 1/8" ish flat bars [been a while, can't quite remember] stacked together to form a square "shaft" that slides through the tube and is held in the center by a female square welded into the tube.  The arms have a female square that slides over the square shaft and locate in the end of the bar. 

    Some that I've seen have a 3 bolt cover over the arm where it slides into the tube that can be used to adjust the friction on the bar and slow down it's movement.  Figuring out a way to bolt that arm down tight is all you need to do.
