Technical Cambelt change

[injector]

Hi, could anyone please tell me when the cambelt should be changed on Ducato 2.8jtd on a 54plate time/mileage- mines done 14500 miles. Thanks for any help

 

[dave]

now, 4 years is up

I think mileage wise, it's around 70000 IIRC (Or the nearest kilometre equivalent as that is how the service book is configured!)

If i remember, I'll check in my service book at work today and post up!


However, Dave is right with the 4 year rule as belts age.

Thanks for that best get it done, are any special tools needed or is it straight forward

 

[John C S]

Not sure about the tools.

It's 48 months or 120000km for replacing the belt though!!

120000km for replacing the belt though!!

that been revised since service books was printed 64,000 km

There seems to be a lot of confusion about when the timing belt is due for a change.

In a lot of service manuals and owners handbooks are intavals quoted of up to 80,000 miles and up to 10 years. This might have been the general consensus at the time being an we are not disputing this at all.

The largerst timing belt provider to automotive industries (at time of writing) is Dayco. Dayco supplies timing belts to the production line as well as to all after market suppliers.

Dayco has revised the timing belt changing intervals to 36,000 or 3 (three) years. This is due to the fact that the belt failure rate has increased in recent years dramatically over the three year period. This is not due to lower manufacturing quality. The stresses in the environment in more modern engines are much increased and therefore can't last as long as in comparatively less stressing conditions.

The fact that a lot of timing belts do not snap well above the three year period or the 36,000 should not lead to the conclusion that it is not necessary to change the belts earlier than the previously promoted recommendations.

Everyone be advised that the intervals set by Dayco are a safety recommendation to safeguard many engines that might suffer valve damage in case the timing belt brakes. But more importantly the manufacturer is also aware that a broken timing belt might bring the driver and other occupants of the car into life threatening danger, which might even extend to members of the public that are passers by.

It is therefore rather wise to change the timing belt at 36,000 or three years or if not known when it was done rather the earlier than later.

If anyone would like to argue about it with anyone here, just point to this thread.

Contradicted your last post Dave!

They are very easy to change,no special tools required.I recently changed one that had done 120k and was 5 years old and still on the original belt.....please don't try this at home though!.

Contradicted your last post Dave!

the quote is from dayco not from me

if you have a dayco belt fitted by a registered fitter, dayco them selves will pay for any damage done if a belt fails before the the times they have stated, even if the belt has been fitted wrong
