Dino Saga 060212 _ Adjust forks in gear box

45 minute shift fork job took 2 hours but transmission is perfect.

Next time it might take 1 hour. You learn! Scraping off the old gasket and filling with oil takes the most time.

Finally caught up with Jack and got time on his lift Saturday morning. He showed up in his bicycle racing suit and he was quite a figure. Skin tight suit with sponsor’s labels all over. He has seriously retired and I was cutting into his practice time for a March bike race. He did paperwork while I pulled things apart. Just as expected, 1- R fork had shifted. Put a wrench on the locking bolt and it was just snug but not tight. Everything else was tight so loosened fork, moved it left 2 mm and cranked bolt down. Perfect.

Jack got into the car and ran through the gears while I watched the levers move. Left/Right neutral was not quite on. He held the lever while I loosened the front lock nut, turned the transmission shaft 2 deg. and tightened things back up. Now right on. The front threads on the hex adjusting sleeve are right handed so there is no confusion when figuring out which way is tight. The rear threads are left handed and will louse you up every time.

The key to setting the transmission is to have the Ferrari tool that holds the 3 detent springs in place when the transmission cover is off. Of course no one has one. Made my own out of two scraps of 0.09” sheet aluminum. 0.06” steel is fine too. The drawing makes things clear. Nothing is critical. Holes are oversize. Stack the two with 1 – R rotated 45 deg. Use washers to get 1 – R the exact height.

Car feels great now!

Here is a picture of the tool I used. Being a prototype, some details needed adjusting. Note the elongated clearance hole for the 1 - R spring guide. The drawing is a cleaned up version. There was no reason to cut away the corners of the larger piece so the final corners are square. Hope this proves useful. It made the adjustments a trivial project except for the draining and re-filling of the case.
