Violent shake.

[Terry Wilkerson]

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?

 

[Seth Swoboda]

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

 

[Terry Wilkerson]

King pins have been changed. No loose steering parts either.

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

 

[Don T]

Are you talking about clutch chatter or is it after the clutch is fully released?

 

[Terry Wilkerson]

I will check the motor mounts.

 

[Terry Wilkerson]

It happens just as the clutch engages the flywheel.

 

[Terry Wilkerson]

I was just thinking us it possible pinion angle could cause this?

 

[OhioRick]

Here’s an option.
Engine steady rods.

 

[19Fordy]

Those steady rods won't fit a 1950 Ford.

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 .

Did you have the shake prior to doing all this work?

 

[1939mars]

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

 

[Terry Wilkerson]

Yes the problem was the reason for changing the clutch parts. Turns out the clutch was not the problem.

The free play is set to 1 1/4.

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.

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.

Yes I had a new pilot bearing installed by the machine shop.

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?

I don't know the history of the engine. It does run pretty good. Starts with no hesitation. The clutch wasn't oil soaked. I had the flywheel resurfaced.
Earlier in this thread I mentioned pinion angle. Do you think that could cause a shake?
