I have read in Wurzels beam guide about 'setting' the torsion bars when rebuilding a beam. He states that, after fitting the torsion bar to the radius arm using the eccentric washer and bolt, you should then wind the stud, on the other end of the torsion bar, fully into the end of the torsion bar. Next is to tighten the nut on the end of the stud to pull the radius arm towards the beam tube, until tight, then back the stud off until it touches the 'plug' in the arm of the trailing arm.
My question is, is this all that stops lateral movement in the radius arm? I ask this as surely there will still be a degree of 'play' in the threads of the stud, therefore allowing the arm to contact, and wear the seal under cornering forces .
I have tried to explain this as well as I can, any questions/answers are much appreciated!!
Thanks
