The pressure plate is not fully releasing (clutch pack is bad)
The purpose of a clutch on a vehicle is to disconnect the drive of the engine from the gearbox (this would be required when the vehicle is stationary or to change gear). While the engine is running the crankshaft is continually turning, It is the crankshaft that turns the gearbox and via the gearbox the road wheels. Obviously there are times when the engine is running but drive is not required, The clutch is the mechanism by which this is achieved.
You would need someone to look under the vehicle at the drive shaft while you try to move. If the drive shaft spins, but you don't move, its the rear end. No spinning drive shaft, then you have no clutch.
With a little practice you can start a vehicle in 1st gear and shift gears without the use of a clutch. This would be only to get you safely home or to a garage.
At the clutch plate and the pressure plate.
If the problem is only happens when you take off then I would think it is clutch related; Oil on a clutch will cause it to grab,chatter etc. Also, if the clutch has a lot of miles on it, it may be just worn out.If this jerking happens as you drive the vehicle during acceleration , then your vehicle has some tune-up issues such as spark plugs, spark plug wires, cap,rotor.
To remove the clutch the vehicle would need suspending to access better. After it as been lifted the motor mount and clutch can be removed. Replace and return parts.
First of all the vehicle must have a manual or (stick shift) transmission. Then you will... 1.)Turn the key on as you would normally and leave it ON. 2.)Push the clutch pedal to the floor and hold it there. 3.)While holing the clutch put the transmission in 2nd gear. 4.)Have someone else push the vehicle to 10mph or as close as you can get. 5.)Release the clutch pedal and push the gas pedal 1/2". The vehicle will shake a bit and will come to life this is when you need to depress the clutch again as to not stall the vehicle. Easy. 5 steps. Just make sure you have enough room to drive the car. ALSO** you can substitute step 4 if you can get the vehicle to roll downhill
Clutch bearing may be going out on kompressor.
The clutch parts that wear out would be the clutch master cylinder and the clutch slave cylinder. Replacing the clutch master cylinder requires disconnecting the hydraulic line, unbolting and removing the master from the vehicle, bench bleeding the new master, install the new master then bleeding the system. Replacing the clutch slave cylinder requires removing the transmission assembly. I would recommend purchasing a shop repair manual for that vehicle if you want to DIY.
it would work perfectly well as it did and still does on the Vincent motor cycles of the fotties and fifties their clutch was centrifgal the initail drive being taken up by a single clutch plate as then centrifugal part of the clutch came in as the revs increased
depends by the vehicle you drive
First check for mechanical interference from the clutch mechanism to throttle linkage.
