I'm pretty ignorant when it comes to gearboxes so forgive me if this is a stupid question. In the next couple of months I plan on taking the gearbox out of my 109 to give it a refurb, the first time I changed the oil in there a synchro hub spring came out, the last time I changed the oil another spring came out in the oil. Now, given that there are only 3 in there to start with, what's likely to happen if the third one was to fall out? Would I lose the use of those gears or just lose the synchro on them and have it work like an old crash box?
