I think the 05xxxxxxx means the belt was manufactured in 2005, but the question is how to decode the rest of the numbers. Thanks
Anyone have ideas on how best to store belts? Bought a set last June and won install until this comming June. BTW... I couldn't find any date codes on the ones I have just a similar part #
This sounds a little dumb, but think about it, the ageing of tires is much more important then a simple cam belt in any car. So, If we look for a belt manufacturer that its consern of good quality tires, then we might be close to a good belt manufacturer then. Worth a thought! /Orkyl
I was not aware there was anything wrong with the ones we already had. Tire companies, you mean like Pirelli and Goodyear? You are a little late. I have always found it difficult to fix something that isn't broken.
rifledriver: I dont know, but something is wrong with the feith of the belt we have. Their age and miles might be a joke, how long and how many years?, I dont feel any quality in any brand of any cambelt. Every 30k miles or 5 years, hold your thumbs?
I am sorry but I have no idea what you are trying to say. If English is your second language excuse me, try saying it another way and I will try to understand your meaning.
Carmine, This question came up earlier this year. These two threads should help: http://ferrarichat.com/forum/showthread.php?t=93252 http://ferrarichat.com/forum/showthread.php?t=87470 Barry
I agree. Carmine, your belts appear to be Ferrari branded Dayco Isoran belts which do not have a date code.
Just that they can't be trusted past 3 years, maybe 5 if you're feeling lucky. I walk the walk, though. I replace mine based on expert opinion from people like you. I just have always felt that the biggest problem wasn't the belt but the rebuild costs. I am taking the fewest chances possible.
Why do you say the Ferrari branded Dayco Isoran belts have no date codes? The local Dayco rep told me the following: 1. In an 8-digit date scheme, the 1st digit is the year. In my case 0=2000 2. The subsequent 2 digits is the week. 52= last week in December. 3. The next digit is the day of the week. 4. The last 4 digits are in series to indicate a batch number. He didn't have data for the 7-digit scheme. But, according to the above rules, that makes Dec 20 & 29 of 2000 the mfg of my belts. This contradicts FoUK as they say they received them from Ferrari on Nov 2005. Comments?
I was of the understanding that Isoran were a division of Pirelli, making timing belts under license of Gates manufacturing. Its is also my understanding the Gates belts have a date code built into the number, the Isorans do not. Scott made a new adjustable timing pulley cam drive that has a vernier scale adjustment. Nick is selling Scotts version as well as a plain set, both of which use the modern HTD tooth design simular to Honda. The original 308 belt is rated at something like 25 HP, whereas the HTD belt is rated at over 200 HP IIRC.
Do you know the HP required to drive the various 308 valvetrain configurations? I would expect that the QV has to be approaching 25 HP under some conditions like starting.
I was just wondering, are T-belts are like Milk? Do they have expiration date where after a certain date it's too old to use?
Well, they should. If time is an issue, not just miles, I bet the material could care less if it is sitting on a cam gear or sitting on a shelf
If you mean a cam pully on a car that's never used, that would be true. I think the rubber compound does care whether or not it's in use or on the shelf. Rubber certainly deteriorates with age, but in use belts bend and flex which produces heat accelerating deterioration and hardening. Add to this heat caused by any friction between the belt and the pulleys. Timing belts will deteriorate faster in use.
I hope the Dayco belts have a few years of shelf life prior to install as well as the belt tensioners. I work a couple of weeks a year in Spain and found that I can get the complete set of Timing belts and tensioners for my 308QV for about 80$ (US) and have been bringing them for some of my F car buddies in the states for years. Dayco belts are labeled #94485, 308/328 GTB-GTS. Mondial Says manufactured in Italy The bearings say SKF BTC8163, Belt Tensioner Pulley, Made in France Blue Box with SKF stamped on it. Funny, under the label that reads Ferrari BTC8163, you can see it is stamped "Alfa-Romeo, FIAT, Peugeot, SEAT (which is a Spanish car) I always buy them in full sets for the QV so have no idea what they charge for items seperately....

That is exactly what I mean. Many of our cars just sit and sit and sit, then 5 years later get the belts changed because its been 5 years.
