Larry Schramm Posted January 13, 2010 Share Posted January 13, 2010 With the engine off and you depress the clutch, does the clutch move in and out easily or is it hard to operate. If it is hard or sticks or hangs up in certain spots, that could be the problem. You would need to look at the clearances and condition of the transmission input shaft to the clutch spline. Make sure the splines for the transmission are really clean. Link to comment Share on other sites More sharing options...

JFranklin Posted January 13, 2010 Share Posted January 13, 2010 In Italy there must be a good shop that can go over your parts and rebuild what is faulty, and then balance the assembly. Remember some of the fastest and finest cars have been built in your country! Link to comment Share on other sites More sharing options...
Joseph P. Indusi Posted January 14, 2010 Share Posted January 14, 2010 I replaced the clutch (rebuilt pressure plate, new clutch disk, new throwout bearing and pilot bearing) on my 1948 Buick special sedanet. Got them all from Kanter. The first disk they sent was the wrong one but they sent the correct one the next day. Never had any problem. There is one little problem that may occur if you are not aware of it. It is the No-Rol or Hill-holder if the car is equipped with one. This is a small hydraulic device connected to the clutch pedal by a rod and the brake hydraulic lines. When facing uphill and stopped, you were supposed to press on the brake with the clutch pedal all the way to the floor. If you release the brake the hydraulic device kept the brake fluid from returning to the master cylinder thereby stopping the car from rolling backwards. As you let the clutch up from the floor the hydraulic device would let the fluid return to the master cylinder, unlocking the wheel cylinders, and the car would move forward. If this is not adjusted correctly, it will drive you pazzo until you figure it out.If vibration is the problem, you will have to asssure that all the new parts you installed are correct and balanced.Bona Fortuna!Joe Link to comment Share on other sites More sharing options...

critterpainter Posted January 20, 2010 Share Posted January 20, 2010 Matteo: Some Buick owners are installing late 50's Chevy clutches and clutch discs in their Buicks. (the same clutch as used on 59 vette) I do not know all the secrets to doing it, however it is mostly a bolt-on operation with the parts to watch being the throw-out pivot and the length of the actuating arm. Is your flywheel balanced??? I would think a chebby clutch should be findable in Italy with little problem. The original style clutch used in that Buick is long obsolete and good ones are getting hard to find.Bill Link to comment Share on other sites More sharing options...
Guest Matteo bosisio Posted January 20, 2010 Share Posted January 20, 2010 Thanks Bill,i will investigate this solution....in April i will be visit friends in Texas, so it will be the right time to get the proper parts.....i will take the clutch out, so i can start look into the modification. yes, flywheel and armonic balancer are fine...the problems that i suffer is only while start moving the car after as soon as i relief the clucth and gets attached to the flywheel everything is fine....it is unpleasable because causes the car to shake durin the biginning of the motion......

Ben Bruce aka First Born Posted January 20, 2010 Share Posted January 20, 2010 Sounds like what I call clutch chatter. More than one possibility. Oil on the clutch plate. Bad motor mounts. Ben Link to comment Share on other sites More sharing options...
