Clutch Chatter
How do I fix clutch chatter starting up in first gear only. I have a cut down flywheel, V8 pressure plate, and a clutch disc three years ago. The problem started then. Where do I start. Thanks John

Re: Clutch Chatter
I find chatter comes from flywheel cover being out of spec [.007"], flywheel being out of spec [about .003"] , or pressure plate fingers out of spec [.002"].

Re: Clutch Chatter
Sounds like an alignment problem. If you didn't install the two shims at the top of your flywheel housing, that can give you trouble.

Re: Clutch Chatter
I'm not sure which figures I'm off on. I couldn't get my cover any better than .009" [ from .034"]. I'm pretty sure Fords spec is tighter than that. I like a flywheel to be better than what I mentioned, but, thats about the worst I would run. I try to get the plate fingers all within .002" or better. For a long time this one would shake your dentures loose, all is well now. |

Re: Clutch Chatter
I worked part time for a clutch rebuilder, sometimes a disc will cause a chatter until it gets "smoothed" over with a little use. Sometimes there might be a slight thickness discrepancy in a spot on the lining.
Chattering on take off can cause high & low spots on the lining. Minerva chattered BAD in LOW. Second gear take off DIDN'T chatter. For a month, I took off ONLY in second, I "think" that evened out the HIGHS & LOW spots. After that, smooth as glass on LOW gear take offs. On cars where, after humid storage, the steel "threads" in the disc & the flywheel rusts together & the clutch sticks, like locked up! After breaking it loose, the clutch "might" chatter. I "think" the second gear take off, "might" help smooth out the flywheel & disc surfaces & eliminate chattering. It's a DAMN site EASIER than puttin' in a new clutch! Clutch chattering is fairly common on Model A's & sometimes, by experimenting, you can learn to take off, "chatter free", like, take off at idle speed, in low, THEN gas her up & GO!!! I once put a SOLID center disc in my Nailhead powered, '53 Studebaker, DON'T EVER DO THAT------------------MAYBE YES, ON A RACE CAR. Bill W.

That alignment tool is nothing more than a copy of the transmitter input shaft. Before they were available an old input shaft or homemade copy was used. If the transmission is installed, the disk is in alignment. |

I was born in a Studebaker parts room and brought up in Stude and Ford stores. My fathers favorite car was his 53 black on black Commander. He kept it for a long time. Sure wish we still had it. I still think they are one of the prettiest cars ever. These threads sure do get side-tracked don't they. |

Re: Clutch Chatter
If you want to check the run-out on the flywheel, I'll help you tear it down this winter.
I'll even help put it back together if you supply the barley pops. |

Re: Clutch Chatter
I agree with Bill. Mine chattered a little when first installed but became normal in a very short time.

Re: Clutch Chatter
Mine also has a chatter. I start in 1st with the spark lever up and it seems to take off with less chatter.
Have a question for someone that knows more about this than I do. But I have just the standard motor mounts in back and front. Could the adjustment of the front motor mount have anything to do with the way it chatters? Reason I ask is that when it chatters, it seems like the whole rig shakes and I was thinking maybe the front was to tight.

Try taking off in second for a month. Just let it take off at idle speed & then gas it. "Might" help it smooth out. Bill W.
