    Just got SCM February issue, had a story on belt change intervals. Forgot the author (Same person who wrote about the expensive maintenance on the 550 -?Sheehan?).

    Article basically said:

    3 years is ridiculous
    5 years is ridiculous
    8 years is about right
    12 years might be ok

    Now, we know this has been spun about 50 times or so. But who ever wrote the article, clearly reads the posts on here, as much of it was a rehash of opinions on here.

    But there you have, some brave soul stated 8 years was good enough...

    Anyone else read the article?!

    I ran 2500 miles over the weekend once, on 12 year olds, but that's just crazy!

    I think we should lock the subject or merge every d@mn thread so they make no sense! LOL!

    He doesn't own a Ferrari as far a I know (Martin) and Sheehan is brokering other's cars, so he has no vested interest! He's selling a Boxer due for service right now!

    You either care for your machine....or you don't! End of subject.

    Too many different years, too many different designs, CAT vs. NON CAT......

    I also read the SCM article and posted about it a few days ago. As has been posted adnauseam, it is not the belts that fail, but the tensioner bearings that then cause the belts to break or skip a few teeth...When I first bought my 1982 BB512i in Dec 2002, the last time the cam belts had been changed was 1991...I drove her until Feb 2003 when I had a full service done including cam belts...the cam belts and tensioner bearings were perfect...it has now been almost 4 years and I think I'll go 6 or so before changing them again...

    I'd only JUST bought the car...2,500 miles from home!

    So it wasn't 12 years of MY life, but his! Only 1,000 miles since new (in 12 years!) so I tossed a coin and headed out into the night........

    I'm a chain guy but I'm amused by the belt threads. My own take is that bearings fail more often then the belts, you need to drive the car to get better belt life, you have to keep them dry/oil free and you can't tell by looking at them if they're okay unless they are damaged.

    If I had a Ferrari belt car I'd change them when I got the car and then go 7 years, based on the anecdotal evidence on the subject. I happen to think when installed correctly, odds are if they last 3 years they'll last 7.

    Mines got 7 years on them and in for service now. Unless something changes I will go another 7 - 8 years before next belt service.

    My Stradale just past it's 3 year anniversary and I replaced the belts et al. Belts looked good but a tensioner had failed-collapsed. The service may be overkill but it's better than the possible cost of an engine. The cost of doing belts, bearings and tensioners is not cheap but it's miniscule compared to the risk of an engine failure. As Harry Callahan said "do you feel lucky today?"

    I'd say it's time for a sticky FAQ. And, hand out medals to the regulars, especially the consultants, who *politely* answer the same questions over and over again.

    Actually, he said "Do you feel lucky? Well, do ya, PUNK?"

    The appropriate answer is....

    No, I don't - my TR is going in for a major this week.

    Ferrari doesn't give you any choice in the matter. If you want and extended warranty you have to do all of the required services, belts, tensioners etc. by them and have the car inspected by them. Total equals about $13,500.00 for the first year of the extended warranty.

    mike sheehan is one of the most knowledgable people out there when it comes to ferraris. he is intimately familiar with the cars and is a great source of information. he does not share the sneering attitude you find so often in sports car market.

    We have quite a few highly knowledgeable ferrari people on this very forum as well. But i would bet a bag of sweets :)D) that they have very different professional opinions regarding ferrari maintenance. I have yet to see the pros agree on very much regarding certain subjects.

    I suspect that Mike Sheehan is correct in his assessment for 308s, especially 2v cars. In the end it comes down to the four quadrants of risk management. Belt failure is a medium to low probability, high consequence event. Each has to make their own decision as to how much risk they can handle.

    Yeah I'd guess that Keith Martin would recommend belt changes every 20 years so as to blow up more Ferrari engines and make them even less valuable in his eyes (the V8s, that is). By the way, did anyone hear that he was kicked out of the last Barrett Jackson auction for vociferously announcing that the muscle car market was a bubble and was soon to burst? I guess the BJ brass didn't like hearing that at the event, hehe! I don't know who to hate more, KM or BJ. I think KM is right about the muscle car thing, and glad he made his opinion well known, but by the same token, BJ just proved to the world that they're nothing more than a money hungry operation.

    Cheers,

    to replace the belts here in Oz it costs about $200 a year (assuming 3 years between changing the belts) which is good insurance in my book and then changing the bearings every second belt change works out to be $60/yr .

    Why would I put this off for such small outlay ?

    Install 2 belts on a 308 without bearings for $600. I'll do that with California labor rates. Line em up. Thats a parts cost of $80 retail. That leaves $520 for about 3 hours work, 4 if you haven't done it before.

    With that kind of profit I will have my 599 in no time.
