Violent shake.
So to start with I have a 1950 Ford Custom. I have replaced the clutch, pressure plate, throw out bearing and hub. I had the flywheel resurfaced. It also has new u joints.
From a dead stop the car shakes hard. It smoothes out after the car gets moving. It's only on a start. I do hear a mechinacal sound some times when at speed. Any ideas? |

Re: Violent shake.
Have you checked all of your steering coponents for wear or anything that is loose? Drag link, tie rod ends, king pins?

Re: Violent shake.
King pins have been changed. No loose steering parts either.

Re: Violent shake.
Check the motor mounts (and the transmission mount while you're at it).

Re: Violent shake.
Are you talking about clutch chatter or is it after the clutch is fully released?

Re: Violent shake.
It happens just as the clutch engages the flywheel.

Re: Violent shake.
I was just thinking us it possible pinion angle could cause this?

Re: Violent shake.
Here’s an option.
Engine steady rods. |

Re: Violent shake.
Those steady rods won't fit a 1950 Ford.

Re: Violent shake.
Broken rear leaf on spring pack , loose or broken shackles, loose u bolts to axle housing .
Of course youve already checked the obvious clutch possibles . Trans mount and motor mounts or oil on the disc or a bad pressure plate . |

Re: Violent shake.
Did you have the shake prior to doing all this work?

Re: Violent shake.
Is there any play in the clutch pedal when it is all the way up? If not the clutch may not be fully engaging.

Re: Violent shake.
Terry, I read where you installed most all the New clutch parts,
but curious, did you install a New Pilot bearing/bushing too ? A wore out pilot bearing/bushing will cause one heck of a shake. .

Re: Violent shake.
I had the same issues in 1960 on my 50 Ford. I had the flywheel resurfaced. Should have had it balanced at the same time.

Re: Violent shake.
Tell us about the engine. Is it newly rebuilt or an older engine? Someone mentioned an oil soaked clutch and yes, that will cause a violent chatter when you let the clutch out. What is the surface of the flywheel like? Does it have hot spots?
