Does sound like fried clutch. The only wee blot on the horizon is the potential for a blue flywheel, that will need facing/replacing.

Cheers

oh dear what is that???? sorry i am clueless.

thank u 4 ur replies!

v.v.v.v helpful!

when the clutch slips, it gets very hot. this heats the flywheel up, and can end up causing a 'glazing' of the friction surface of the flywheel. that makes it difficult for the new clutch to grip the flywheel.

so if it has got really really hot (how long did you spend trying to move it with the slippy clutch) it could've damaged the top surface - and need skimming/facing or replacing.
 
Clutch engages with the flywheel, the 2 come into contact if you have fried your clutch you may have damaged the face of the flywheel aswell from the friction.

Learn to drive on a clutch properly btw, alot of new drivers need new clutches in the first year because of the way they use it.
Do you keep your foot over the clutch when driving? If you did this down the motorway you may have had it partially engaged.

Always have your foot off the pedal completely!
 
ohhhhh ok i c!

i always thought i was quite careful with the clutch but did get it off a new driver! maybe i am just as bad! it was my 1st motorway journey so i dnt know maybe i did without thinking!!!! :confused:

how much does this cost?

will def make sure i am EXTRA careful with clutch!


thank you for all you replies!!!! lifesavers!:worship:

I use Shop4parts and find them really helpful.You can order at http://www.shop4parts.co.uk

Or call them and they will tell you what's needed. Then you need a good garage to fit the clutch. Get them to change the gearbox oil while they are on the job.

New drivers tend to over -rev the engine when pulling away especially on hills - can really stress the clutch. Obviously you don't want to stall the engine but with practice you should use no more revs than it needs to pull away smoothly. Also learn to listen to how the engine sounds. When the revs rise and the car doesn't build speed as quickly you'll know the clutch is starting to fail. Hopefully it will be a long time before you get to see this in action again.

But I guess its not a new car. The clutch could have been on its way out anyway.
 
Thank you soooo much!!

will def have a look! thank you for all your advice!!!

also i have just had another go at reving and now the engine seems juddery when revving although revs rise??????

OH DEAR!!!:confused:

Emzy,

Sounds like you're new to this so here's a short "teach-in".

The clutch connects the engine power to the gearbox. There is a thick circular metal plate bolted to the engine crankshaft. This is the flywheel. It has a ring of teeth round its edge, used by the starter motor to crank the engine.

Whenever the engine is running, the flywheel is therefore spinning. It's called a flywheel because it has some mass and this helps smooth out the rotation of the engine, much as a flywheel used to do for steam powered engines.

The clutch is fixed to the flywheel and has two main components. First there is another thick circular metal plate that is pushed towards the flywheel by strong springs. This is referred to as a pressure plate. It rotates with the flywheel.

Sandwiched between the flywheel and the pressure plate is a disc with friction material on both sides. This is called the driven plate or clutch plate. The friction material is similar to that on brake pads/shoes and that's what smells when it gets too hot and burns. The centre of the driven plate has a splined hole. This slides over a splined shaft sticking out of the gearbox. This is the gearbox input shaft.

When clutch is engaged (foot off pedal), the driven plate is gripped tightly between the two steel plates, under spring pressure. The power from the engine is therefore transferred to the gearbox and, if a gear had been selected, the road wheels turn, otherwise the gearbox input shaft just spins without any further power transmission (hence you can rev the engine in neutral).

When the clutch is disengaged by pressing the pedal, foot pressure operates the clutch master cylinder, hydraulic pressure transfers the movement to a piston in the clutch slave cylinder and a fork presses on the clutch release bearing (sometimes called the thrust bearing) which operates on the spring mechanism of the pressure plate. The pressure is now relieved, the flywheel and pressure plate continue to spin, but the drive chain, from driven plate, through the gearbox and differential to the road wheels is no longer powered. This allows gears to be changed or the speed to be reduced or stopped, without any effect from the engine.

When releasing the clutch, the driver's careful control of the pedal position ensures that the springs of the pressure plate gradually apply pressure to grip the driven plate and once again establish full power transmission to the road wheels via the gearbox.

Clutch problems include (in no particular order):

1. Driven plate linings worn, clutch slips, quick test is accelerate hard up hill in second gear. If suspect, the clutch will slip, engine revs will increase without road speed increasing.

2. Pressure plate worn/damaged. The release mechanism consists of spring steel fingers that get worn or cut off. Often associated with strange clicking noises.

3.Release bearing worn/damaged. The bearing referred to above is between the clutch release fork (non-rotating) and the pressure plate fingers (rotating). This small bearing does a lot of work and is prone to seizure or other failure. It it generally renewed whenever the other clutch parts are renewed. Faulty release bearings often make whining or rattling noises. The noise will be different (or stop) when the clutch pedal is depressed.

4. Hydraulic problems. The hydraulic system is quite basic: master cylinder, pipe, slave cylinder. However, the slave cylinder is in a hostile area and prone to damage of the rubber seals or ingress of debris. The hydraulic oil is shared with the braking system so it pays to keep an eye on the reservoir. The oil is an effective paint stripper so caution with spills/leakages. It is also hygroscopic (absorbs water), which is why manufacturers recommend periodic renewal and why it's not a good idea to put old oil back in the system.

5. Driving style. Rule is foot away from pedal except when changing gear. Resting the foot on the pedal ("riding the clutch") keeps some pressure on the release bearing, promoting its early failure.

Now, on to clutch renewal. As mentioned by a previous poster, you can pick up a three piece clutch kit for around £50. I've done Mk1 and Mk2 and price was about the same. The three pieces are driven plate, friction plate and release bearing (you know what these are now don't you!). You will probably entrust the job to a garage but if you want to know what's involved, see my guide on this forum.

Get the genuine Fiat clutch kit from Shop4Parts and take them to your favourite garage. Job done. Ask them to change the gearbox oil at the same time and to check the gearbox input bearing before they put it all back together.

A new slave cylinder is also a worthwhile doing as the original will probably fail before the new clutch wears out.
