Clutch freeplay
I’m playing with a project started by someone else.
Right now I have over one inch distance between the face of the throw out bearing and the pressure plate fingers. By the time I take up the free play, I don’t have any pedal left. What’s wrong? Bob Giles |

Re: Clutch freeplay
Have you adjusted the clutch fingers themselves? If I remember correctly, with the clutch and pressure plate bolted securely to the flywheel, each finger should be adjusted to 5/8" from the release bearing surface. Check Les Andrews' or other reliable service manuals to verify the adjustment before making adjustments to the pedal free-play. After replacing the clutch disc I adjusted mine to that measurement and my clutch is silky smooth.

Re: Clutch freeplay
Free play is not measured between the fingers and throw out bearing. When depressing the clutch pedal the distance from "full up" to sensing contact between the throw out bearing and clutch fingers should be about .5 to 1.0 inch or so. That will ensure the throw out bearing and clutch fingers are not in contact with the pedal full up, and sufficient pedal travel is available to completely disengage the clutch and avoid gear clash.

Re: Clutch freeplay
I second Mulletwagon. The free play is at the pedal, not at the throwout bearing. There are instructions in the "Red Book." https://www.snydersantiqueauto.com/p...0031&cat=41621

Re: Clutch freeplay
Thanks, I’m hoping the fingers need adjusted. Looks like a new pressure plate.

Re: Clutch freeplay
The pressure plate adjustment was way off, over 1 inch. The nuts are not reusable, and I can’t find replacements. Would a nylock nut work.

Re: Clutch freeplay
Use high temperature nylocks, red nylon I believe

Re: Clutch freeplay
If using nylocks make sure that the adjusting screws are deburred enough so that they don't cut up the nylon making it ineffective. Alternately, if there's enough thread on the adjusting screws you could just "double nut" it.
