Hello All, sorry to restart an old thread. Thought I would ask here since you guys seem to know what you are talking about. Long story short. My clutch cable broke, so I replaced it, along with bronze bushing upgrades. I followed all the procedures in Bentley and in the posts here to install the clutch cable.

Now I am at a point where I am unable to increase the cable travel distance. I am at 22.4 mm, after setting the 1.0 mm gap at the stop bolt of the small lever on the tranny. My pedal stop on the pedal cluster cover l is all the way up, since I was trying to go from 23 to 25 mm. What should I do, or should I start over? By the way I drove the car before I adjusted the travel distance and did not notice anything unusual (compared to how it drove before the cable broke). Any feedback is much appreciated.

You should be able to take out 2.6-3.0 MM at the ball connection at the pedal cluster. Of course re-check measurements.

DRACO, if I understand correctly, I need to adjust the 20 mm distance at the lock nut and cable clevis on the other end of the cable inside the pedal cluster? Thanks.

Oh no, you wrote you are getting 22.4MM, the goal is 25.0 MM(+/- 0.5) so loosen the jam nut at the clevis and start dialing her out but not too much to achieve the proper throw at the pedal ergo around 3.1-3.5MM out to give your cable some slack. lock the jam nut. Then re-measure.

But even before this make sure the cable is sitting correctly, that Bowden metal turn should be in the proper orientation. Take a pic and post for us. That could be the reason why you have no slack in the cable???

Just to be clear. The 20 mm is the nominal distance (as recommended) at the clevis end inside the pedal cluster that I set for the lock/jam nut, when I installed the new cable, and that is what you want me to reduce by 3.1 - 3.5 mm to get extra slack at the transmission end under the car? I thought for the extra distance of 2.6 mm I need for the cable travel, in my case, I need to adjust the rubber stop at the plywood pedal cover, which is where I am not having any luck. In fact after moving the rubber stop UP I got 22.4 mm whereas before adjustment I got 23 mm. Don't know if my measurement accuracy will impact as well.

Regardless I will check everything, and post some pictures of my cable assembly under the car. Appreciate your help.

That omega (sp) spring and bits and pieces are a bit rusty, I'd give them all a good spray with something like WD40 and work the clutch pedal quite a few times then repeat over a day or two.

It worked for my SC.

Okay you are losing me. As I understood it, after clutch arm adjustment of 1.20MM gap ( make sure there is no play, back and forth, this will throw your readings off ), with the cable on properly and tensioned to 1.00MM, then we move to the next adjustment the Pedal Throw, by measuring the end of the cable ( example 65MM, only ) and having a helper press the pedal in all the way ( example 40MM ) to find the difference. If at 22.4MM you need to adjust the pedal stop, if maxed out the the clevis until you get optimal throw of 25.0MM +/- 0.5MM ( 65 - 40 = 25, number are for an example ).

Is this what you did?

Basically one is clutch engagement adjustment other is pedal throw adjustment.

So if you are only getting 22.4MM differential then it means you need to tighten the slack at the clevis or max out the stop at the foot board to it's end to try to obtain 25.0MM throw. Hope this makes sense?

If I am mistake and your box only needs 20.0MM then you would lower the stop and/or loosen the clevis, but this seems strange for a 915 gear box. Fellas???

Yes, cleaning the Omega ring will help.

Draco, yes you got it. That is what I did. The 22.4 mm I get is cable travel distance (pedal throw as you call it) difference between pedal up and pedal down (with helper). So, looks like since I already maxed out the stop at the foot board (moved it all the way UP), I need to look at clevis end on the cable inside the cluster and adjust the lock nut (this is what I probably confused you with my 20 mm value). The range for this is 17 - 22 mm per Bentley Manual so I have room to play with. Sorry about all the confusion. I still am planning on getting some pics this weekend.
