My car is at MR Clutch and the mechanic claims the slipping clutch has damaged the flywheel and it'll need grinding back at a cost of £49.99? Is he telling me the truth?

It is possible but not very likely. The driven plate - the part with the friction material attached - has the rivets on the side which engages the flywheel set deeper, so that the side facing the pressure plate will wear to the rivets first, causing clutch slip long before the flywheel side reaches the same stage. If it were me, I'd go in and have a look - if they're honest, they won't be offended.

Yes.
Clutch friction material is held in place by rivets and when the material wears down the rivets contact the flywheel and 1) the clutch starts slipping as the rivets take the laod and 2) the rivet grind away at the flywheel.
If the flywheel is damaged and you dont have it "ground back" or "Faced" there will be a loss of gripping surface for the clutch friction material of perhaps 20 per cent in total which will accelerate wear, may even cause slipping immeadiately and could very well make the clutch action fierce or juddery.
If the flywheel surface is not absolutely flat or nearly flat and highly polished and burnished have it ground, it is the cheaper option because there will be no warranty on the clutch if you ignore the garages advice. If the grooving is particularly deep or the teeth round the flywheel damaged a new flywheel or good second hand one, might be a better answer as there is a definite limit to how much can safely be removed from a flywheel.

It is possible but the clutch would need to have been slipping for quite some time. By the way, on most of the modern day cars, you cant reface a flywheel as they have a 2 piece flywheel to give a smoother clutch take up. The only remedy is to replace the entire clutch and flywheel assembly which in some cases could be around £800-£1000. The price qouted for refacing sounds reasonable enough and you should have some guarantee with the work.

Damaged Flywheel

Labor will cost next to nothing because it's already apart and they're looking at the flywheel. At the least you should have it resurfaced or if that's not possible or practical get a new one. Any high spots or heat checks or other defects even those you can't see by eye from the previous clutch will cause premature wear on the new one and shorten it's life. Replacing a flywheel later on is every bit as expensive as the clutch because it's the same amount of work.

Yes, it is possible.
The friction material on the clutch plate contacts the flywheel when engaged.
If the clutch was so badly worn that other parts of the plate assembly (rivets etc.) were able to contact the flywheel, damage may well have occurred.
If you are unsure, call in unannounced and ask to see the damage.
£49.99 isn't bad value.

yes he may be telling you the truth. Most flywheels if you have ever seen one out of a car. Are riveted together. So once the clutch has worn down the rivets are exposed and start to touch the flywheel causing grooves etc. Cant you ask to see the flywheel before they do it tho ??

He is probably telling the truth when a clutch goes out it usually cuts groves in flywheel from the steel rivets in clutch plate and also when a clutch is slipping it builds heat and will warp the fly wheel and leave heat stress cracks, and most clutch manufacture will not honer warranty if you dont have fly wheel turned ( Ground back)

They always say that ,ask to see it the flywheel ,the facing should be flat with no heavy scoring .minute lines would not hurt a new clutch . fitting new flywheels is a good way of loading your bill
Damaged flywheels can damaged a new clutch

yes it can and resurfacing is the usual remedy but don't take his word for it ask to see it. if it needs resurfacing it will look like it has three or four grooves ground into the flywheel this is caused by the rivets that hold the friction material on the clutch plate becoming exposed due to excessive wear £50 seems a fair price if it has to be done
