    I own a 98 355 Spider (for the last 4 years). Last year during/after the cambelt change and major service (18750 miles), I noticed that the car was difficult to get into revers from Neautral and 1st (relatively OK from 2nd) In addidion it sometimes feel that when I put the car into first that it was done by not using the clutch (based on the sound). I had a thread her last year,and I revisit the workshop for about a week ago. It is above 600 miles to drive for me to the nearest workshop. The car is still at the workshop, and I plan to pick it up in about 2 1/2 week from now.

    I got feedback from the workshop today that both the clutch plate and flywheel was a "bit bent" and the next step was to change the coupling.
    If the flywheel have to be changed it cost approx 7000 US including VAT but exluding labour. According to the service man the flywheel has been grinded before without getting "good" (So bothe the flywheel and clutch plate had visibile damage), this is out of my knowledge, the car had a milage of approx 12000 miles when I bought it for 4 years ago. (And the ferrari workshop in Norway does not longer exist)

    Anybody know if it is possible to repair the flywheel?
    Is this an "engine out job".
    What is the price for a 355 flywheel "over there" (US)?
    If I only change the clutch assembly and the flywheel is "bent", is there a big risk that i destroy the assembly again?

    Hope for some replays and possible advices.

    Have a nice weekend (mine is already destroyed even if I know "that you have to pay to play" by owning a Ferrari)

    It isn't hard to replace the flywheel. I don't think they are being straight forward with you. How can the flywheel be "bent"???????? It sounds really fishy to me. I dunno mate, I think they are trying to stick you for some extra work. You may need a new clutch, but you can get the flywheel resurfaced. It is really hard to say without looking at it. If it really is "bent" I would just get a good used one. Try looking for one from these guys. http://eurospares.co.uk/breaking.asp I looked and they have a wrecked 355 F1 there right now.

    It's not an engine out job. Actually you can do it yourself. You will need to remove the rear bumper and exhaust, but you can do it yourself. There may be an issue with you bleeding the F1 clutch and setting up the initial point of slip on the clutch, because the shops use a computer to do that. We did get into a discussion a while back about doing is manually, but never really got down to doing it. Though it is possible. So you may want to change the stuff yourself, and then have an independent shop bleed and setup the clutch.

    Run a search of the archives to find the thread on changing the clutch yourself.

    Thanks for your replay, very much appreciated!

    I really hope that is enought to change the clutch with some assosiated parts only. According to the Mechanic at the workshop the clutch plate and disc was not looking to have been used for a long milage (which is true since it has been changed on a other workshop in Norway for approx 5000 miles ago), but they was both "uneven(bent) worn". I paid 3500 US $ in Norway for the clutch change including the labour. I expect the approximately the same at this workshop, but if I have to add 7000 US $ on top of this plus labour, then it will be far more costly than I expect in the first place. The clutch does not slip, but it is certainely something wrong with the F1 system "now and then".

    I was in contact earlier with an Norwegian workshop (not the one which was a Ferrari workshop, which not longer exist) and my impression was that you have to use the computer to change clutch setting and bleed off with an F1 gear. In the aftermath it seems vice to go for a manual gearbox if you should own a Ferrari in Norway :) Have to travel (drive) abroad to find a workshop. And for me this is approximately 12 hours drive on different type of "quality road" with strict speed limits.

    Is there any difference on a flywheel to a manual 355 compare to a F1 355 ?

    Have a nice day

    Best Regards Jostein

    Ernie, I was looking at the attached link from yourself, Price was just above 1600 £ which still is a lot of money but far below the price (1/2) from the workshop. Is this all I need if I have to change the flywheel ? Hopefully they not removed my attached link?

    That looks like the one to me. But like I said, you may NOT need a new flywheel. You may only need to get the current flywheel resurfaced. If your clutch is that out of wack, it could be that they didn't use the computer to set up the initial point of slip on your car when the last owner had it changed, and thus the clutch could have worn wrong, and possibly worn out the flywheel, POSSIBLY. Plus I don't like the price they gave you, way to high in my opinion, and that is just for the parts. You can always get a nice used flywheel that will do just fine, IF you need it. The last time I bought a brand new flywheel it cost me $3,000 U.S., for ONLY the flywheel. So that is why I'm saying that they are charging you way too much for just the parts. All in all I don't like the sound of this place and would take it else where. Or better yet, fix it yourself.

    For sure given those quotes I would dig in and do it myself. I think it was fatbillybob who suggested to just get your clutch resurfaced (not sure how that is done) and do the whole thing yourself. It's so cheap you don't have to worry about the F1 calibration...unless that would cook a flywheel, which is pricey. I have a wrench in hand and stare at my clutch everynight...one of these days it's just coming out!

    Thanks for your replay, I really appreciate the information from you. The reason for this "thread" was to be a bit "ahead of the game", in case I end up in a situation that the flywheel must be changed. I will probably know next week.

    I was the owner during the last clutch change, it was changed at a milage of approx 16000 miles, and at that time the clutch slip "heavily", and I believe that this was the first clutch change on the car.

    The problem occur approx 3500 miles later , and based on your information, I am more or less convinced that the previous workshop dident install it correctly, and subsequent the clutch wear wrong and also possibly worn the flywheel. I cant see any reason why anybody have grind on the flywheel before, I have no record on that in my service book and have been owner of the car the last 4 years, and the milage was only 12000 when I buy it.

    Anyway, I feel that I have some arguments to discuss the part price with the workshop, the price I have got from the workshop is "shelf prices" taken out from the computer by the Mechanic and hopefully the prices can be discuss with the workshop, based on what it cost elsewhere.

    I will certainely change the clutch assembly now, this is the first step. ( and hopefully the last) Then everything will be reset by the computer. If I then by a used flywheel ( if neccessary) shorthly after from "Eurospares" and changed that home, do I have to reset all values on the clutch again after ? Reason for asking is that I have to drive 600 miles to do that :(


    Best Regards Jostein

    Yeah you do, because of the difference in flywheel thickness. Just have them resurface the existing flywheel. All they have to do is put it on a lathe and remove enough material to get the surface even. It's sort of the same thing that is done with break rotors. You only remove a minimal amount of material. You may also want to make sure that the flywheel is not leaking. If it is, you should repack it. Again something that you can do yourself. If you run a search of the archives you will find the instructions of how to do it, as several people here have done it themselves. Basically it is putting in a new o-ring, cleaning out al the old grease, repacking it with new grease, and then putting it back together. Not a hard job, just really messy.

    Thanks Ernie for all your assitance !

    Hopefully the workshop can resurface the flywheel, it is not an option for me to do it myself since I have to drive all the way back and forward to the workshop to adust the setting afterwards. (12 hr drive each way). I have by the way been through a "flywheel tread" after your reccomendation in this forum, most likely it would have been to much complicated for me without mechanical background. (but thanks anyway).

    I guess I will get some more info from the workshop next week, and will then update the thread.

    Have a nice day

    Best Regards Jostein from Norway.

    Please post before and after pictures of the resurfacing if possible. Or at least the "after" pictures! :)

    Thats still way too expensive. The F355 flywheel is easier to machine than many other flywheels.

    I am having my 355 flywheel resurfaced and was going to get it balanced at the same time. (I had the gearbox/flywheel input shaft break and wanted to eliminate a possible source of the problem)

    The WSM states the max imbalance without grease is 250 g/mm. The shop I spoke to stated that this value is quite high and he can get it much better.
    With the Voith damping flywheel does it depend upon a high value for it to function correctly or is it good to get the imbalance as good as possible?

    In an old thread davehelms thought the amount of grease in a 355 flywheel was raised from 150gr in the WSM to a recommended value of 220gr by FNA. Can anyone confirm this?

    Thanks.

    Received a message from the mechanic today that the gear problem seems to be sorted, and my last year struggle to get it into revers is finally ended :)
    The only remaining test is a road test, but I do not expect any negative surprises.

    According to the mechanich the previous workshop which changed the F1 clutch used a grinder on the flywheel, it should also be mentioned that they used a seal assembly with a gasket which "crumble away" with contact with the hydraulic oil. (cost me a lot of money last year to repair).

    I do not have any picture of "before or after" resurfacing of the flywheel, I am currently at work on a oil installation in North sea, and plan to travel by a airplane in approximately 1 1/2 week to pick up the car and drive back.

    Thanks again for all feedback, it is good to be a member of such a forum where it is possible to ask and read about different Ferrari issues.

    Best Regards

    Jostein

    Recently arrived home after 600 miles drive from the workshop, the car is like new :) and have never been better in my 4 years ownership.

    The learning is mainly that not all workshops are capable to work on a Ferrari, even if the say so !. The one in Norway cost me a h... of a lot of money in the last instance.

    Have a good Ferrari summer.
