Got the new third gear set and mainshaft bearing delivered the other day. As I posted in the project thread a while back, I shucked a few teeth off the clustershaft third gear at the last track outing. Given the cost of the gears and bearing, I now have a little more incentive to match the downshift rpms at every corner in a session, not just 99% of them.:laughing: Oh, well.
The first picture shows the cluster shaft partially disassembled to access and remove the damaged third gear, and the new third gear.

This picture shows the cluster shaft assembled with first, second, and third gears (from top to middle).

I got the mainshaft front half put back together before I shut down for the evening. The hard part was remembering how it came apart. I took it apart a couple weeks ago, and I've slept a couple times since then.:laughing: I'll finish the rear half of the shaft tomorrow, and hopefully glue (RTV) the case halves together then too.

I took my Harley transmission apart once. I was so afraid that I wouldn't remember how it went back together that I did it in one day. Took me ALL day. That DN you have, looks a lot scarier.

Got busy with other stuff, and am a couple days behind. Just cleaning the old RTV off the seams and machined surfaces took more time than I figured. Tomorrow ought to be just sealing and bolting the halves together, along with the tail housing, and the front bearing retainer.

I have the DN 5speed in my 80 and I will say the trans is easy to work on when needed which for me was only for inspection after purchase.

I did upgrade to the Long brand shifter and it made shifting much smoother; not as good as an internal rail trans but much improved over the Hurst.
