AJP8 Chain Tensioner Needed

[ChrisPap]

Hi All,
Someone (not me, really) has misplaced the chain tensioner for their Cerbera V8. They don't seem to be available from any of the normal suppliers so I'm calling out to see if anyone has one to spare, or knows where I might get one outside of Racing Green, Powers or Str8six.
Thanks,
Chris

Superb timing Chris !

Sorry, but I don't know where to get one from, in fact, I'm so clueless, I don't even know where the chain tensioner is
BUT
I do feel that I should have a go at 'regulating' mine.
So
May I Oik your post and ask anybody out there where I can find how to do it ?
(and the values involved)

Ta !
(and Sorry, once again}

Might be worth a call to Jules or APM to see if they have one laying about.

Don't worry, it will turn up as soon as you button the engine up again

At least that's what happened to me with a different engine

By the way, if you are replacing the chain, don't forget that you will probably need to reshim the tensioner bolt

The shims are behind the large pin in the bolt

I don't have a spare one but mine was quite worn (83k miles ish) when doing/having an engine rebuild done so I replaced the plastic with nylatron-66 which I believe BMW use for their chain tensioners, probably other makes as well. If someone could supply a drawing with some measured dimensions for the metal part you could get a new one made.

Have a word with Dom at Powers, or send me a PM, as he's had a few existing tensioners relined for engines he has built, including mine.

They're quite agricultural, simple things, but getting the right material, finished and done correctly, with the rivets peened over properly, isn't something you want to take a chance on because of the risk from failure if it's wrong.

They weren't cheap, because it's such a manual process, but it was worth getting done for peace of mind.

The internal tensioner or the bolt?
