Cam timing PDF and question...

Hello. Does anyone have a copy of Skinflint's cambelt timing/change PDF I could have? I've changed my cambelt as part of a front end refurb, Eiffel towers, slam panel etc, and have a horrible feeling it's a tooth out...

Engine turned over a few times manually, no issues, fires up fine but as soon as I take my foot off the throttle it dies, injector light is on.

Any clues from you more knowledgeable folk?

Thanks, Chris

Should be here.. https://drive.google.com/open?id=0B2CHx_WlD4alMFI5R0I1VEVrSmc
Official doc here as well. https://drive.google.com/open?id=0B2CHx_WlD4alWGZraDNlVkV2dkU

If the Injector Light is on you could try Barnacle's StarTrek software to get a diagnostic read.

Thanks ever so much Skinflint.

I'll do some reading and try to find out more about StarTrek software.

I think the HowTo is here.. https://www.fiatcoupeclub.org/forum/ubbthreads.php?ubb=showflat&Number=1612868#Post1612868

Thanks 👍🏻

if you use Startreck you will need an old laptop Win 98

Hardly, I developed it on W2k... I believe it works on W7 and probably W10 (might need a compatibility mode). I can't help you with that though as I haven't used Windows for ten years now; I don't have any Windows machines around.

But... if you changed the belt - did you change the cam sensor at the same time? For reasons I don't know, it's common that it fails immediately after a belt change.

Thanks Barnacle, I didn't change it, benefit of hindsight n'all that... Saying that though, I read somewhere that if the car starts at all its not likely to be a cam sensor failure?

Living in rural France is delightful apart from when trying to diagnose issues with non native cars!

Hi
I have the SK diagnostic. Depending on where you are I could come over and we can have a look.
I am close to Limoges.

Note that the 50nm torque values given for the belt tensioners in both those guides is wrong, it should only be 25nm as specified in the Fiat engine manual. You will strip the nut or stud at 50nm.

See this old thread for more details :

Hi Graham
Sorry to see that the guide caused you extra work with the high torque setting.
Mine was OK with it both times but my torque wrench doesn't feel like it is doing a lot at 50 nm.
Value was taken from the generic guide, however I'd personally choose the high side of 25 nm - it seems low for such a critical component that relies on tension to retain the correct position.
I'll be happy to change the guide to avoid a repeat.

No worries, I'm not knocking the guide as other than that torque setting (which I know came from the other "professional" guide) it was great and I couldn't have done the job without it.

Here are the torque figures from the official Fiat engine manual, fixed tensioner at the top and adjustable tensioner at the bottom. Both showing 2.5daNm , or 25Nm.



Worth at least mentioning the discrepancy and pointing out that 25Nm is typical for a 9.8 strength nut, which is how the official Fiat nut for the adjustable tensioner is marked.

Thanks for all this info folks.
