Torsion Bar

Fig. 6 Door Sill Protractor Position:

Fig. 7 Torsion Plate Or Radius Arm Protractor Position:

If the torsion bar is reset by one spline at its inner end, a 9° change is obtained. If the radius arm is reset by one spline at the outer end of the torsion bar, a change of 8 3/20° is obtained. This arrangement allows a change of 5/6° if the torsion bar and radius arm are positioned towards each other.
1. Install torsion bar into transverse tube.
2. Install radius arm onto outer end of splines.
3. Position a bubble protractor on the lower edge of the door sill, Fig. 6.
4. Adjust so that the bubble is in the center of the glass tube.
5. Position protractor on free hanging radius arm and note arm inclination, Fig. 7.
6. Adjust arm inclination if necessary.
