How does this timing belt look to you?

No worries Ken ---

A lot of people on this forum forget that posting a reply to a thread is OPTIONAL.

If a topic annoys one, and one has responded to it so often that is unimportant to one ----- well, there are other threads to choose from aren't there?

I agree with Glassman ------- Give the guy a break

 

I just got a PM, so I thought I should clarify. Note I didn't say anything about being able to tell if the belts were good, only about if the belts were bad. A belt with missing teeth is bad. A belt without missing teeth might also be bad. A belt with worn teeth is bad. A belt with perfect looking teeth might also be bad.

out.

 

Personally I have no problem with Timing Belt threads. Some are interesting some are very stupid. And sometimes a tidbit of information comes up that really helps.
And as for the search function. Quite honestly the search function sucks. So being that we have discussed every aspect of the Ferrari already, what should we talk about now?

 

Indeed. And, as I no longer use the Pirelli belts, I learned something new from the photo posted in this thread -----

How to say "Do not crimp / bend" in German and Italian!!! (I already knew the English and the French translations )

 

"Abstract: To design low-cost and more robust products, the application of probabilistic methods should be employed. This has been successfully carried out on a timing belt, a key component of the synchronous belt system for driving camshafts, water pumps, fuel injection pumps and balance shafts. The model development process for determining the durability and reliability of a timing belt will be discussed. The timing belt model, based on Miner's rule and the Arrhenius Law, will also be described for the primary failure mode of tooth shear due to cumulative fatigue. This is a closed-form engineering parametric model that considers the belt loads, geometry, mechanical properties, environmental effects and customer usage. The model calibration and correlation against accelerated testing and fleet data, respectively, will be shown. Using an algorithm in BASIC listed in the appendix based on the Monte Carlo simulation method, the predicted timing belt durability and reliability results will be given on an existing vehicle application and an optimised design for the same vehicle, where the belt construction and geometry have been changed. The benefits of using probabilistic methods in the design process are effectively demonstrated and depend on the use of accurate reliability prediction models."

I appreciate the photos -- thanks for posting them! Now I know what 20 year old belts with few miles on them can look like.

 

I think this is an opportunity to test an old, yet low-mileage timing belt. Is there a way to put it through a strength test, and settle once and for all the age-old question that has plagued us all for years around here?

I'd be curious to know if this is even possible. Maybe the darn thing would prove to be OK after all..... NOT THAT I SUBSCRIBE TO NOT CHANGING THEM REGULARLY!
I'd just like to know how much truth is in the factory's new recommendation to change every 3 years, regardless of mileage...

Thanks for the post
Everyone was new sometime

LOL on the socket.

How about some pics of your belt change project?

 

Every belt over three years old.......

 

...is BAD!!!!! LOL!

Next question..........

I cannot see condition or number of teeth, so I have to dip myself and move closer.

Jokes apart, I was under the impression that timing belts are recomended to be changed every two years especially for low usage cars. Am I wrong?

 

Why not have a sticky in the 308/328 section of the more informative timing belt thread. However the 308 section will lose half it's threads and Rob probably can give up a server or two.

 

It's a Ferrari Tech Bulletin I should scan, I have it inserted into my three sets of Owner's Manuals....

IIRC it's "three years, or 30K miles," so I run my cars 'round and 'round the Loop 610 here, at full throttle....to get maximum value!

As you can see, that gal was trying to "stretch" the use of hers, and it failed........now she'll need sunscreen!
I got that out of my apartment computer, I need to make a "WANTED REWARD" poster out of it and paper the neighborhood!

There were several at the pool last weekend, might have been her! Here's the rest, of the vacation!

There should be a gizmo or gadget that one can place so that it can either scan the belts with laser, infrared, x-ray, superman-eyes, that can pre-warn the owner of impending doom. Maybe the emitter on one side of the belt and the sensor on the other side so that there would be some sort of indication.....

BTW...patent pending....

 

I can see it already: "My 'Belts About To Break' light is on. What does that mean? Should I really change my belts, or is it OK to drive it for a while?"

 

Focus, BigTex, focus!!!

Good stuff!

Greg

 

I was thinking more of a green----yellow---red----blood red----loud buzzer---hammer to the head---can not start the car type of gauge for people that don't understand the idiot lights. But I am open to suggestions!

Alan- Here is a nice REPOST for you. Do not tell J.R.

I've purchased things from them without drama. You will probably get a nice note from UPS after the package arrives asking for customs duties.
