Fulvia Berlina 2C


« on: 14 June, 2015, 10:56:47 AM »

Yesterday I ran the car up to temperature to check the idle speed after adjusting the fuel/air mix on the ECU last week . I then refitted the ECU cover and shelf because the shelf had slipped when the ECU cover had been removed to set the mix and was interfering with the clutch pedal return spring. All fixed and decided to take the car for a run but couldn't get it into reverse gear (gnashing of gears when attempted). It seems that the pressure plate is stuck to the flywheel. Perhaps this happened after repeated pumping of the clutch pedal when  checking/adjusting  that the shelf was clear of the spring. Having looked at various websites intend to start the car in 3rd of 4th gear with handbrake on and give the accelerator a couple of sharp dabs to see if that will free the clutch.
Has anyone had similar experience and does my proposed remedial action sound good?  FYI the car is used regularly and clutch gas been fine (disregarding possible need for new clutch release bearing at some time in the future).

Sounds like you going in the right direction by putting in 4th gear and starting car, sometimes they will free off by rocking in top gear, while the pedal is held down with length of wood from seat base to pedal, good luck

No luck with freeing the clutch. Symptons are as follows.
Cannot engage 1st or reverse gear (havent tried the other gears) with engine running.
Can engage any gear with engine off and then start car. In 1st or reverse the car moves slowly when started but can be held easily on foot brake and possibleto rev the engine and hold on brake.
Letting the clutch pedal out seems to better engage the clutch I.e. speed of car increases as clutch let out.
I would assume that if the pressure plate was stuck to the flywheel the car would lurch forwards/backwards when started in gear with the clutch cable depressed. Clutch works after a fashion just will not allow gears to be engaged.

Any thoughts/comments would be very welcome

Adjust the cable in the engine bay?? Seems like it may be about to break as to go out of adjustment is to streach and this is only when about to break....

I think Tim might have it there, especially as you say that you have been pumping the clutch a lot. Some times, if a cable is about to break you can hear it 'suffering'. With engine off, pump the pedal slowly and listen carefully. I have no experience with the Flavia/2000 clutch, but a  clutch cable usually fails close to the pedal or close to to the actuating lever.
Good luck and please let us know what you find.

Cable seems fine. The release arm is moving the correct distance and I have checked that the free play is as per the manual.

Have you adjusted the cable to the minimum slack at c2-3mm at the arm end in the engine bay?

Hi Tim, yes checked it matched the free travel as per the manual which is 5 to 7mm.

Tim, I also checked that the release arm was travelling its full distance when the pedal was depressed

This is a tricky one!

Could the bearing have collapsed? Hence not fully disengaging the clutch?

Colin Clamp, our Flavia guru, reckons that it sounds more like i have perhaps just pushed the clutch down a bit
further than it would normally go and it is sticking on the splines.

Don't understand this as the friction plate is freed by the pressure plate on operating the clutch so stops spinning (or should do) with the flywheel. The pressure plate cannot push the friction plate beyond the flywheel???

I have had 3 instances where a Fulvia clutch has stuck due to lack of use (over winter), and one on a Gamma which just appeared following a long journey and a weeks rest. In every instance I have brutally put in first or reverse depending on what trajectory I need to control the car, foot hard down on the clutch pedal, and other foot on the brake pedal and crank the starter. It always releases immediately with a frightening bang. From your description the clutch is dragging. I would do up the 5-7mm to minimum clearance to see if you can get the clutch to free itself then re-adjust. Its not difficult for a garage to drop the gearbox and put a new clutch in (get your clutch kit yourself - probalbly the Fiat uno 1.4 Turbo (petrol) 200mm will be the best).

Any chance it is an oil leak gone onto the clutch/flywheel mating surface and it is this which although not stopping the flywheel/clutch to move relative to each other is just enough to cause the two to 'interact' whilst the pedal is down? I would suspect if you are brutal (not recommended) you can actually get into 1st with the engine running as this would break the dragging.

Peter, it could well be. I suspect that the release bearing might need replacing but those symptoms (juddery takeoff when engine hot) are very similar to those caused by oil contamination of  the clutch/flywheel mating surface. I have tried starting the car in gear with the brake on but this hasn't done the trick. What is unusual (and supports your theory) is that although I cannot engage gears with the engine running the clutch operates after a fashion if I start the car in gear. The car will start and creep forwards/backwards but will increase speed as i let the clutch pedal out.
I am going to have another look at it this evening.
Thanks to everyone for their input.

Latest update ..
Tightened clutch cable taking out the free play and can now get into 1st and reverse while the engine is running. However now have clutch slippage because the cable is too tight!
