I converted my car a few years ago to a 915 transmission, with a 74 release fork. I find that the clutch pedal has to be pushed all the way down to release the clutch (yes, the free play is correct). I was told that there is a difference in the length of the clutch lever arm length on the pedal assemblies between different car models (911 vs 914). Does anyone have any experience with this? I'd love to shorten the pedal travel, though I realize it will increase the pedal pressure needed to release the clutch.
If anyone has a picture with the measurements, I'd love to see it. I can remove the pedal assembly, replace the bushings, and try to modify the arm at the same time. |

I just realized I didn't answer your question, which was how long the release arm is on the 911 shaft for the 915. It's 47mm, the shaft is 14mm diameter, and the shaft length is 162mm from the center of the hole for the roll pin to the driver's side edge of the release lever. The shaft length all the way to the the pedal end is 175mm, and the release lever is 5.5mm thick. The factory shaft has an offset in it, as does the stock 914 shaft, and this offset is 12mm. The 911 shaft is 16mm longer than the 914 shaft, so the stock 911 plastic spacer is 16mm long, but my spacer had to be 28mm long.
