I know this wasn't the topic of this thread, but I thought I'd help N2Boost out with these pictures.
This is the 5th gear followed by the brass synchro and then the selector ring/collar. (From bottom to top).
Here is the stack again as they sit in the transmission.
Here is what it looks like with the selector ring/collar disengaged. My hand doing the job of the shift fork.
This is what it looks like with 5th gear engaged.
Here's what it looks like with the selector lifted off.
And with the synchro removed.
All three pieces separated.
This is the two main pieces of the selector ring/collar and inner spline assembly. Normally two ring springs and three retainers hold it together and allow them to slide up and down a bit separately.
Here they are together. The three open spots are where the three retainers go.
Here are the dog teeth on the selector ring/collar that have been torn up causing 5th gear pop-out.
Here they are again. Torn up. Chipped teeth.
More carnage.
Here is what the other side looks like that hasn't seen any use in it's life. This is what it should look like more or less.
More pics of the good stuff.
Here are the dog teeth on the 5th gear itself all torn up causing 5th gear pop-out.
Another picture of the beat up dog teeth. You should see now that with all this material gone the teeth don't have much left to hold onto.
Here is my brother's 5th gear that we replaced ahead of time before it could get 5th gear pop-out. It looks a lot better.
Again.
Good one on the left, bad on the right.
Here is the bad one again. You'll notice the distance between the gear teeth and the dog teeth is very small. Maybe 1mm at most.
The redesigned gear will have 2mm or 3mm between the gear teeth and the dog teeth. Basically they sit up higher. This means they penetrate deeper into the selector ring/collar and do not loose contact and slip or grind themselves up. Take a look back at the picture showing both gears next to each other. You'll see neither is the redesigned gear even though they both came out of 1994 transmissions.
If you have the gear with the "taller" dog teeth you're all set. Otherwise it's a time bomb. You'll know when you take it apart.
