Pedals
How smooth are your pedals (clutch and accelerator) when you press them slowly towards the floor? Mine feel kind of "jerky", like they could use some oiling or something. Is this something others on here recognize? And if so, is there anything that can be done to "smoothen" their travel?

Here's a write up that was posted by a member on the Porsche club GB forum:
First how do you know if you have this problem? Well if you press the clutch pedal, and the cylinder shaft doesnt move, likelihood is your roll pin has broken. (you will need the pedal board off to check this).
Here's what you do.
1) Remove the floor pan/board (or if you have a RS carpet, well...you can work that bit out.). My floor board is secured by 3 x M5 hex holts
2) Remove the small ball-joint securing clip on the back of the throttle linkage, where it secures to the throttle pivot. To do this, reach behind the pedal, feel down the rod, and flick the clip around, it will now pull up and out.
3) pop the ball joint of the throttle linkage off.
4) Now you can see all 3 screws securing the pedal board (as one is hidden by the accelerator pedal. Unscrew these 3 screws (philips, with washers)
5) Remove pdeal board
6) Remove brake linkage clip, and take linkage off the pivot
7) Remove clutch linkage clip and take linkage off the pivot.
8) Undo 2* 13mm nuts securing clutch master cylinder
9) Pull down the connector for the brake light switch
10) Remove ball joint clip on the throttle -> throttle cable joint, push cable ball joint connector off.
11) Remove 4x 13mm nuts (and washers) that hold assembly to floor pan.
12) Lift assmebly forward and up (to clear studs), if tight remove throttle pedal (2 x 11mm nuts)
With whole assembly on the bench
13) Remove the clip on the clevis pin, that secures the clutch linkage to the clutch spring., and remove clevis pin.
14) Slide clutch pedal assembly out of shaft, and remove spring linkage.
15) Remove reminants of Roll pin, and clean holes.
16) Grease and reinsert clutch pedal mechanism, and attach spring linkage on the end. Align the holes.
17) Tap new roll pin in (A Birmingham Screwdrive may assist here )
18) Ensure roll pin is visible to the same extend from both sides.
19) Assembly is the reverse of removal (Always wanted to put that!)
Its worth cleaning the general area, and regreasing the other bushes on the pedal assembly at the same time. During reassembly, dont forget to ensure that all the clips are put back on correctly. The clutch pedal height can be adjusted by the long screw, with a small (4mm hex bolt) that is secured in the white spring carrier. Be careful not to move the clutch cylinder too much when lining backup, as it is attached to a solid pipe.
