the tapered pairs of faces contact the clutch body
(1), synchronizer ring (2) and, where applicable, an
intermediate ring. The engine's gear is run at the
speed of the corresponding drive-side gear; only
then do the locking splines (4) release the
remaining travel of the shift collar. The shift collar
travel from neutral to complete engagement in the
relevant idler gear is approx. 0.3 in (7.7 mm).
