Help! My Big7 is stuck in 1st gear!
#24
If lock up occurred as 1st engaged then the cone may have wedged. But there should not be sufficent travel for the balls to emerge. The hub is not constrained and is free to work its way toward 2nd, so may occur afer a time in 1st. Normally the travel is limited by the cones rubbing but if these are very worn, or the 2nd gear assembly can move away more chance of the balls emerging. Similarly if 1st gear is engaging excessively deep because of selector adj, selector wear, stops filed etc the tottl travel available is increased.
A myriad cunning devices have been devised for assembling synchro balls, which, like ign switches, best done in the middll of a lrge bare room under a sheet!
