Excellent! So now are you ready to help me get the internal selector and shift forks lined up? That's my project for the morning, as the gearbox rebuild for the BB should be completed today. BTW, excellent race...last I saw Ferrari had a 30 second lead, then I fell asleep. Best of luck with the rest of your project! David | ||

David, thanks so much for your help! I just finished watching the European Grand Prix, read your comments, bottled it into my head, and got under the car. True and behold, within a few minutes it engaged into gear. Third gear to be exact. After that I adjusted the position of the stick to be even between second and third. Twisted the nuts to hold the rod assembly in place and done. Now I can run through all the gears no problem. Thank you very, very much! Arnaldo. | ||

If the clutch assembly is in place, spark plugs in (and the transaxle is definately in 2nd gear), you shouldn't be able to easily turn the rear wheels. Conversely, if the rear wheels tun freely, you're in Neutral. I know...obvious, but important to get the selector shaft in the correct position. Do the rear wheels turn freely: Yes If this is the case, all the shifter fork are lined up, as in the previous pictures. When you twist the shaft, you should be able to feel some resistance as the male piece on the input selector drags across the three forks. Very slight in and out movement will be possible. If this is the case, you are certainly engaged...and done. If the input shaft moves freely in and out...you're in either in front of, or behind the gear selectors. Do the rear wheels turn freely: No (Still in 2nd) If this is the case, all the shifter fork are not lined up. The middle shaft is now moved rearward by about .400. Twist the shaft CCW, and now push the shaft rearward. Once completely rearward, turn the shaft 20 degrees or so CW, and start pulling it forward. When it stops, likely the input shaft male piece is now resting on the selector fork. A slight CCW turn, coupled with a slight pull forward and you will be above the 2nd/3rd gear selector. Twist CW..and now the shaft shoud not want to move in or out without substantial force being applied. This does take a bit of practice....but rest assured that no damage has been done, nor does the transaxle cover need to come off. All in all, near zero force is required to do this. The only time you would need to apply force to the input selector is if you were trying to engage, or disengage a gear. It can be quiet frustrating to get these guys to line up...Though usually not a big deal. Feel free to drop me an e-mail...and I'll walk you through this. | ||

David, the car was in second gear when I disconnected the rod. Now, I can get to a lot of position with the shaft which I am visualizing as been the 5 gears. However, none seem to engage the transmission. How do I know the transmission has engaged? I rotate the rear wheels and they move freely in all positions of the shaft. When you mention that I have to twist to engage, in which direction should I twist and with what strength? Thanks for your help! | ||

Caribe... I'm assembling a BB/TR gearbox now, and perhaps can walk you through the steps to get the seclector shaft back into the correct position. Before we start, what gear was the car in "before" you disconnected the shifter linkage? In the below pictures (before rebuild), notice the three shafts. Starting from the bottom, RM/1st, 2nd/3rd and 4th/5th. Currently, in the picture, the gearbox is in Neutral, as the "square U-shaped" notch in the selector forks all line up. (There are three forks there, each behind the other...but, difficult to see from the pics.) The input selector (ultimately from the shifter) has a male retangular tang which (depending on the initial angle) will select one of the three forks). So....first verify visually that the input selector is not sticking too far out of the transaxle case. If it is, turn the shaft clockwise and push it back towards the case. Then turn it counter clockwise and pull it slowly towards you until it stops. At this point, you'll be resting on the rearward side of the slector fork you want to engage. A slight twist and the fork and selector will be engaged. If you started disassembly with the car in Neutral, the selector should be horizontal, and be able to turned axially about 45 degrees. On the other hand, if you disassembled while in 2nd gear, the middle shaft will be moved towards the rear...and you'll have to visualize the twisting and push needed to engage the selector. Hope this helps, David   | ||

I have been trying unsuccesfully to get the car into gear for the last few hours so that I can re-attach the transmission connecting rod. The WSM indicates that the shaft sticking out of the gearbox must be in a horizontal position in order to get the transmission on second gear, then connect and secure the rod. Well, I have not been able to get the shaft to turn into a horizontal position at all. I can move it back and forth and about 45 degrees left or right but never to a horizontal position. By the way, in none of the positions that I have been able to set the shaft at, the transmission seems to engage (check by turning the rear wheels). Does anybody knows the correct approach to set the car into gear by manipulating the transmission shaft? Thanks. |
