: As the re-assembly of my engine nears completion, I am rapidly becoming mechanically dangerous.Now that I have the flywheel mounted, I am debating about adjustments to the depths of the "fingers" in the clutch pressure plate.

: In Les Andrews' recent book, he talks about a proper depth (from the flat of the back surface) being 5/8".Some of our Club members have told me that clutch spring pressures are tricky items to adjust, and that if mine had not presented a problem beforehand -- well you know the rest: if it ain't broke, etc., etc.The depth of my fingers from the flat of the surface is a uniform 1/4", and they offer a fair amount of resistance when I attempt to push them in.

: Does anyone have any experience on adjusting clutch pressure plates?I have been unable to find any written articles on the subject.

: Thanks in advance.

Gordon, Thanks for asking this question as I am in a simular position. The fingers on the clutch on my 30 where so badly worn that I have replaced all but the last two fingers. That I hope to finish tonight.I found an old clutch with very good fingers,no wear.The originals look like they were backed all the way until they touched against the flat side of the unit.The wear was extensive showing a clear inpression of the bearing on the fingers ends that worn thru more than 50%metal wear on fingers ends. I'll check that 5/8" from the flat side and see if it is close to the wear pattern on the fingers.Is there any sign of extensive wear on your fingers? If you did not have any trouble with the original set up and have not replaced worn springs or fingers,why adjust something that doesn't need? I have only replaced the bearing of coarse and the fingers. I know I need to get re-adjusted,so anyone out there been there! Thanks in advance for the input.
Fred
PS I just got CDA censored for using the singular of fingers in the text above.
