Hi there.

I'm currently a student in New Zealand studying Autmotive Engineering.

It is the holidays at the moment and we have an assignment. AND IM STUCK lol

We're doing this assignment on Timing belts and i'm stuck on 2 very important parts.

First is: Tensile Strength of a timing belt and its materials. I understand what tensile strength is to a point but i have no extra information.

Second is: Tensioning Procedures. The books we have been given to research the topic does not hold information on the tension procedures. They have to include the following: Spring Loaded, fixed and pressurised chamber.

Any links, comments... just any helpful information on this stuff would be great.

THanks heaps!

Guess no1 wants to help.

Of course folks here want to help. Speaking for myself I don't have the info on this and some of it costs big bucks to get.

Different countries may have different specs for parts which could lead to different procedures.

For tensile strengh I think inquiring from large manufacturers would be the best resource.

The United States can and does have a host of different regulations on what can and can't even be sold here that varies state to state.

Example: State of Maine now checks your car for inspections that the tires are exactly approved by the manufacturer.

Massachusetts does not allow brake qualities to be sold at anything less than OEM requirements.

Just for the US the regulations change all the time. Many new cars can't be sold or imported here unless upgraded to spec.

The US did stop the VW Bug in it's original layout but other places kept making and selling them. That was mostly that the car could not get thru the rigid safety requirements without a total re-make of the car which VW did finally and they are back in force and seem popular again.

The world is welcome here but specific info may require searching out local regulations of what was sold there.

Best of luck. If someone else here can add insight to this I'm all eyes to see it,

cheers mate. I today recieved a copy of a $200 book from my boss at work. All the info i need on Timing Belts however the Tensile Strengths as you said mite need to be looked up per manufacture.

Cheers for the response.
