 |
|
Hi everyone  ,
I'm building a 1959 vw beetle from bottom up and yesterday we did a test run. As you can see in the video, when I try to give the clutch, it makes a huge vibration and I can't complete that process(giving the clutch).
Any ideas about which causes this problem?
Thank you

| Not enough curve on the Bowden tube can cause it, so can a bent disk, warped pressure plate or rough flywheel |

I have to agree with SlalomBuggy. I would give the same list of potential problems.

One more I would add to the list is broken mounts for the clutch cable tube in the pan

I once had a beetle with a broken bowden tube retainer that shook pretty hard.

I just helped my brother-in-law with the same problem. Turned out to be a bad pressure plate.
Pull engine and with pressure plate/clutch assembly still attached to flywheel, put a straight-edge across the ring that the throwout bearing contacts, and measure to flywheel in several directions.
If measurements are all the same - and I mean all the same - the pressure plate is good and might be one of the other suggestions mentioned above instead.
Best,
Thom

| Is your front transmission mount good and tight? And, no broken nose cone? |

Yup-----the way that thing is bouncing around it has to be more than a chatter
caused by a bowden tube or a funny pressure plate. The engine looks like it is trying its best to leave the car.  |
