hey guys-
i'm starting to get a pretty bad shudder when i pull away, mostly when the car's cold. once it warms up it goes away except when hot it almost groans (slips?). mechanically, the gearbox works good and i don't get any negative feedback from it- it feels like the clutch--- right? is there an adjustment to try, or is it toast? thefleur |

My experience tells me what you are feeling is almost always clutch, do you know how many miles are on it? If you opt for a new clutch I bought the 911 6 spring and matched pressure plate from Jake Raby and boy is it smooth.

Could also be some contamination or bedding in if you used an old clutch with different flywheel or pressure plate.

First check the mounts. You may have a bad or loose mount. Then check to see if you have oil leaking and getting onto the clutch. Are you using the same clutch that came with the used engine? It could be shot from age or the pressure plate could be dead from rust from sitting in the field for many years.

Yup, look at motor/transmission mounts. Apply lifting pressure to the motor with a floor jack, and see if it separates from the mount bar.

thanks guys.
i don't know the miles, the engine's in pretty sorry shape compression-wise, but the gearbox is schweet. I have a sachs/flywheel combo from my 2056 raby that i could throw in there- the mounts are tight, that was the first thing i checked- rick, it is the whole drive train from that car we got. clutch, (resurfaced) flywheel, the whole works. chappy and i agreed it looked ok when we put it back together. i'll check for oil leaks. how can i tell if oil's getting on the pressure plate without pulling it? paul |
