Function
Before the shift collar (3) positively connects the sleeve carrier with the corresponding idler gear, the tapered pairs of faces contact the clutch body (1), synchronizer ring (2) and, where applicable, an intermediate ring. The gear on engine side is brought to the rpm of the gear on the output side, only then do the locking splines (4) enable the further travel of the shift collar. The shift collar travel from neutral to complete engagement in the relevant idler gear is approx. 7.7 mm.
