1988 SBC, KEP 9" flywheel, 228mm HP pressure plate, 228mm kevlar faced disc. TOB from Renegade matched to the KEP parts.
The clutch will disengage, but only very close to the bottom of the pedal travel. In fact, I had to remove the pedal stop. There is almost no free play in the pedal at this point. If I add more free play, the clutch will not disengage. I understand the "fix" for this is to space the pivot ball towards the clutch. Is there any way to determine how thick of a washer to use? I'd dearly love to do this once. (IMG:style_emoticons/default/smile.gif) |

I poked around this morning and learned a few things...not the least of which is I've got a lot to learn. (IMG:style_emoticons/default/unsure.gif)
The probable primary cause of my problem was that I did not install the clutch bearing guides...90111682511. My car came to me without the engine, but the trans was still in the car. The guides were not there and I didn't know there were such things until I studied the exploded drawings this morning. It looks like they will move the TOB closer to the PP. On order now. I also found out how to determine if I have the right clutch fork geometry BEFORE I reinstall the engine/trans. If I still don't have the right geometry, there are at least a couple of ways of moving the clutch fork forward. Post #17 here... This thread... And post 181 here... Thanks everyone for your help. Hopefully I'll do the research next time BEFORE I start asking questions. (IMG:style_emoticons/default/smile.gif) |

If your pedal feels resistance only 1/4 inch in and does not release the plate until the pedal is on the floor no amount of shimming at cable will help as the arc is off for the TO bearing. The only other thing it could be at that point would be a broken cable that stretches under load or the clutch tube or bowden tube was broken. |
