Broken DURATEC I need to understand ..and repair

[marcos59]

At first sorry for my bad engish !

 

On a 260bhp spec 2.0 Duratec

 

Origin: Broken oil pump belt (or lost belt but seem to be impossible)

Result: No oil pressure immediatly ...and 1 rod damaged and probably crank too.

 

I need to understand.

- How this type of belt can broke or be lost ?

- My belt was 1/2 that seem std size for this type of belt....but after research I found 3/4 belt...origin of problem could be size of belt ?

 

As I'm French and live near Calais I search a southern based Duratec Specialist to check engine an change all necessary parts: Where can I go ?! (Originaly engine have been built by HWR but it is too at north for me)

 

Few picture on belt installation and damage here :

Note pictured belt is on ly to give an idea of size (it's not fully at the right place)

Ammo on here of Raceco fame is in Woodbridge in Suffolk so fairly near Harwich/Felixstowe docks for instance and 'only' 140 miles from Dover, I'd start there as he is very experienced with duratecs now

I believe it is possible for a stone to be thrown up which goes between the belt and the the pully wheel which forces the belt off the pully - I don't have a duratec or a dry sump system so could be wrong.

 

I have a red GRP, bare ally 7 with a zetec - I've a feeling we met a couple of years ago in the Central Massif?

You're right Allen ! Very good memory it was 2 years ago

Hi Marcos,

 

I'm running my Duratec with the same Pace dry sump pump and the your belt looks almost identical to mine, I've been using this for 4 years now and never had a problem.

 

However the spacing of the pump from the engine is very important to ensure the correct belt tension. I also suspect that if you were unlucky a stone could get in there and damage the belt causing failure. Do you know what condition the belt was in last time you checked it?

 

Ammo is away at the moment on holiday (2 weeks I think I'm afraid), however if you'd like to talk about the problems drop me a mail offline. I'm based about 40minutes from Dover so maybe able to help out as a courier to get your engine over to Ammo if you'd like to go that route.

 

Cheers

Thanks for your kind offer Rob I will email you offline.

 

I'm sure AMMO is the way to go. I was not aware that is location is not so bad for me.

 

You're right spacing is very important and was checked first after failure: It is perfect and oil pump have been mounted on a big alloy plate so it is very rigid.

 

It was on Le Mans Bugatti track..not many stone there.

 

Conversion was make 3 years ago and belt condition was good as far I have seen.

 

Just unlucky I worry as I don't found belt..so I will never know if it broke or not.

Marcos, I don't want to dprive AMMO of work but there is an engine builder at Angers who could sort that for you.

 

Luke and Sylvia Bourcier. (very nice people)

Thanks for your advice Norman but as I live in Calais AMMO is nearer than Angers for me !

Ammo is away at the moment but if you want to contact him, email him via the Raceco (Raceco.com)website as I know he is checking emails while he is away or try his mobile.

Thanks metal mickey I will email him tonight

I will PM you about exaust. As my engine will probably go to Raceco perhaps I could take with me my 4/1 to know if you could adapt a raceco silencer on it.
