Installation position: position flat on circumference of synchro-ring
towards input shaft (not as yet fitted) (arrow -1-)
- Insert spring.
Installation position: hook single angled end into recess on synchro-
ring (arrow -2-). Turn double angled end anti-clockwise and hook into
opening in bearing plate (arrow -3-)
