So originally I mentioned that the transmission had some bad habits, Originally I did the linkage bushings and adjusted the clutch then adjusted up the shift linkage. It was a bit better but still not quite right.
That being said this thread never did do a great job of the amount of time I spent waiting on things during the engine build. Ultimately it took around 7 months of having the motor scattered to the wind. The heads even went to Germany to have hoeing motorsport do the machine work. They are also known as Wicked Sixes.
Regardless of the reasons it for the delays it caused me to open up the trans and just see what we had on our hands.
Ultimately, I found that we had some broken parts and worn out teeth.
I started with throwing the entire thing in our parts cleaner. Under rated tool right there.
During the disassembly part the main shaft nut was found to be hand tight, Nothing good about that.
turns out the hub? (Unsure on term) that holds the shift sleeve had one half of the three feet broken off. Not sure if this is common or not. However once I started looking into this it seems that Porsche updated it on the later cars. The update consisted of larger asymmetrical dog teeth meaning I needed the shift sleeve the hub and both sets of dog teeth. A unexpected expense but what can you do.
committing to owning a old car is committing to unplanned expenses.
I replaced all the worn dog teeth I needed, and then a whole fistful of synchro's.
While doing this I managed to not have to remove the shift forks from the rods making re aligning all of this a lot easier.
The main bearing in the case was actually really loose, that's a common problem on these mag case 915 trans. The motor was "healthy" and after talking to the previous owner he was not kind to it. Knowing it was thrashed a lot i was not surprised to find this.
It was tight enough i chose to put some sleeve lock into it and pressed it back into place. Will it hold? So far it has. I know its not a forever solution.
None of this would have been possible or nearly as successful with out the help of my Porsche shop owner and friend Frank, Hes retired now but still has some willingness to help. hes been a great asset on Porsche stuff or talking baseball.
