Thanks to John Greco for sending me the bolt length information for five speed transmissions via personal e-mail.
If you have ever replaced the clutch plates, you know that you have to be careful during reassembly to align the inner teeth on the clutch plates and the outer teeth between the intermediate plate and the flywheel. Failure to do so will result in a bent intermediate plate and/or clutch plates that are difficult to engage with the clutch hub from the transmission. Doing this by hand without a special tool can be tedious.
If you remove the clutch hub from the transmission, you can use it to align the inner teeth of the two clutch plates. As for aligning the intermediate plate, what you really need is some way to compress the springs before installing the ring gear so that you can visually see the teeth engaging properly. Fortunately, the end of the crankshaft is threaded and you can use a long bolt through the center of the clutch hub for just this purpose.
The only thing tricky about the bolt is it's somewhat uncommon thread pitch of 1.5 mm (1.25 mm and 1.75 mm are the common thread pitch sizes).
- Four speed transmissions use a clutch input hub that is approximately 34 mm thick. This requires a bolt of the following size: 12 mm × 1.5 mm × 70 mm
- Five speed transmissions use a clutch input hub that is approximately 53 mm thick. This requires a bolt of the following size: 12 mm × 1.5 mm × 90 mm
