Clutch Disk Chatter
My Model A started sometime ago clutch chattering. If I didn't ease the clutch peddle out it would just shake my pickup in reverse something terrible.
I have the engine out and removed the pressure plate and found the disk greasy and the groves on the back side kind of filled with dry mixture of dust and grease. I did notice that the throwout bearing had too much grease pumped into it as it was on the face of the bearing in gobs. I think this if my problem causing the chatter. Your thoughts appreciated. |

Re: Clutch Disk Chatter
It could be that for sure. Oil or grease on the disk is one of the main causes of that. The lining might be compromised now depending on how long it has been wet.
Thre other main cause is you have a clutch disk without any springs, which is either a very old original style one or some poor truck replacement.

Re: Clutch Disk Chatter
Most throwout bearings these days are sealed. These days when you grease the throwout bearing you are basically only greasing the trans snout. Go lightly as not much is needed.

Re: Clutch Disk Chatter
Loose motor mounts can cause chatter.

Re: Clutch Disk Chatter
Yes, It appears that you found the problem with all the grease and dried up stuff. Wash everything really good to get rid of all the old grease. Do not wash the throw out bearing. If it is still good, just clean the old grease from the outside and it should be fine.
DO NOT get any oil or grease on the new clutch facings. I would also just before you assemble every thing to wipe down the friction surfaces of the pressure plate assembly and the flywheel with lacquer thinner or acetone to be sure they are absolutely oil free. Use caution if you are purchasing a new throw out bearing. There are some very poor quality replacements out there. Also, I would only purchase a new clutch disc from Bratton's. They have the best quality disc available. Some other replacements are made off shore and do not have the proper provisions to capture the springs and they will come apart. Replacing the clutch disc is a lot of work so use the best parts available. My opinion. Chris W. |

Now you have to determine where the oil came from. Usual culprit… rear main seal. |

Re: Clutch Disk Chatter
Seems like you found your problem, that'll do it. Too much grease thru the collar has to go somewhere. If you have an original type bearing that can be greased, too much grease thru it will get slung all over.
I don't find the clutches have much oil/grease on them. The chatter then is usually flywheel/pressure plate fingers. |

Re: Clutch Disk Chatter
Use new throwout and pilot bearings, of the best quality, when re assembling. You don't want to do this again in a few months or years.

Re: Clutch Disk Chatter
Over filling the oil pan can cause excess leakage onto the clutch face and that can cause chatter. It happened to me. I burned the clutch dry by slipping the clutch while revving the engine, and the chatter disappeared.
