Chaps, I’ve just fitted a Termi system, and am swapping the foot peg across onto the new hanger, it’s loose and floppy (a symptom I’m sure many of us have experienced)I thought I must have mislaid a spring, but don’t seem to have parts 21 and 22 in this drawing, any idea what they are?
According to the fiche here they are a spring and a ball bearing as Rman suggested. this would explain your floppy pillion foot-peg as they give it the positive engagement when in the down or up position. Probably fell out, with the assistance of the spring, when it was taken apart. The base of the fitted foot-peg would hold them in their well.
