Technical 8140.43 cambelt change

[Leedsred]

Hi folks
Cannot find a definitive answer to the interval change
When I bought the motorhome I was told 100k miles or 70k miles
It's a 2.8 idtd engine from the year 2000 NOT the jtd
Can anyone advise

I can give details according to AutoData Timing belt manual if you provide Engine Series Number.
Note interval for replacing belt are on time and mileage , so which ever is soonest!
However this Forum is littered with people who have taken their expensive Motor Home to have that job done, ending up with catastrophic engine damage due to incompetent repair and vehicle unusable. A quick search on Forum will confirm this statement!
What often seems to happen is the job is done and seemingly OK for 200 miles or so and then belt goes slack due to tensioner issues, resulting in the valves meeting the pistons, which is bad enough, but due to this engine design it then bends the con rod, so a total rebuild at great expense. Customer is often told they just need to replace the damaged valves and refit cylinder head. However a quick measurement on piston height with it's matching partner will usually show one piston lower down the cylinder bore than it's partner by around a couple of mm, this means the engine will never run smoothly until corrected.
This often seems to mean vehicle is off the road for many months whilst legal arguments about who is going to pay!
I am long retired so not getting involved, but have done this job many times in the past, mostly on Iveco Daily's, but some Ducato's with the same engine Series. Also stripped and rebuild the engines after others have caused the damage.
Having said all this, a competent owner or a good mechanic should have no major issues in doing the job as it is a fairly simple design and apart from cam belt job when due , along with regular oil and filter changes these engines are very robust and have been known to exceed 4-500,000 miles. A couple of mine had over 200K miles.

Thanks for reply Mike
I'm taking it back to the workshop who changed belt 9 years ago it's done 40k since then, belt is ten years next April 2025.
It's a lhd a class hymer
I think engine no reads 230CLMBB 1D 1.48

Perhaps that should have been 100k km or 70k miles, if sooner than 5 years. I view the cambelt life as an age and mileage related event. Due to low mileage travelled, I have adopted a policy of every 6 years on my 2006 2.8jtd, partly because this fits with other time related tasks.

I entrusted the first change to a local garage. I was charged considerably less than quoted, "Didn't need to change the rollers." was the reason given. Some time later I discovered that the upper timing belt cover was broken across towards the bottom. My investigation revealed that superglue or something similar had been applied. I have myself, carried out the two subsequent changes.

The belt tension is static on these engines. About 500 miles after my first change, I decided to take up any developed slack by loosening the belt tension, rotating the engine through two revolutions by hand and retightening the clamping nut to specified torque.

As regards belt detioration due to ageing, I think back to my employment when some very .large "O" rings were changed as part of planned maintenance. This was an expensive operation involving scaffolding for access. When testing the replaced "O" rings leaked to an embarrassing extent. It turned out that the "O" rings have a shelf life, and that they had been purchased as spares, at about the same time as the original plant.

Good job you included the Chassis plate.
The Engine Series is the the 8140.43 bit
Which in hind sight I see was in the title. Duh!
My 2012 book only goes back to 2002 on Ducato so the JTD engine, which is basically the same but doesn't use the timing mark for the injector pump being common rail, however I have included the Iveco section on the similar engine which show the 2002 version of that engine Series, so does include injector pump details.
So if you study both you can see both options.
My other book is the 1996 Manual which only lists the Ducato with the 8144. Series engine. but in this earlier book it shows the Iveco 8140.61 2.5 litre which also shares similarities.
Sorry if too much information, so check Series numbers and ages at top of pages.

I got the vehicle from a business that had imported many European MHs in the years before Brexit.
The garage did all their work so am confident in their ability.
I contacted them about 3 years ago they had it on their database and said its not due for another three years.
But as we regularly spend winters in Portugal and the ten years was approaching I got a bit edgy.
The jtd engine appears to be needing changing around 5 years but there was nothing conclusive about the previous version of said engine so I thought I should consult those with the knowledge

The Iveco section lists a shorter time interval
If you are happy with their work on these engines and can recommend them, you may want to inform other MH users on Forum as it does seem to be relevant
