|
|
Since day one this clutch has been shuddering and chattering upon release. I have shimmed the Bowden tube quite a bit but it only helps a little.
Just how much can this be bowed before I am in a situation where the cable is sawing through the tube?
Have contemplated pulling the engine and putting a Sachs pressure plate in there.
Its also not real pleasureable to drive with aged knees  _________________ Never blame lazy people, they didn't do anything. |

Hi,
That happened to me once all of a sudden. I saw the cable had already cut the tube and was getting caught in it.
I tried to put a copper tube on it but impossible since I didn't want to lower the tranny, so I took a worm clamp and tighten it to the point the cut tube would get together.
At least that solved my issue. Been 3 years now. _________________ 1970 Beetle Turbo 2109cc MS II EFI, W/M Injection, Intercooler, FORD Wasted Spark Coilpack, 48lb. Injectors. |

you need to pull the motor and inspect all 3 items carefully .
disc, pp and flywheel .
you will find your answer by looking at the contact areas _________________ B.C's fastest street legal vw , June 2006 Hot VW's feature car 9.81 sec at 145.26mph.

I had a shuttering problem on a 67 bug many years ago, it turned out that the rear most weld on the clutch tube had broken. You might check that- good luck-Bob |

Later VWs had a longer lever arm for the cable to pull on. Lengthening your existing one will relieve the stress on your knee.
100mm center-to-center is the factory upgrade arm. _________________

I had already planned pulling the motor but the reason was to get rid of the Kennedy PP. and put on a Sachs Amartex one I have.
First I'm shimming the Bowden tube with another washer or two and hoping that takes care of it. _________________ Never blame lazy people, they didn't do anything. |

I quit using solid center clutch discs. If your set up is inclined to chatter or grab the solid center disc will bring it to the fore in a heart beat. _________________ Our cars get old, we get old but driving an old VW never gets old! |
