cams, belts and chain

[Alpine]

does anyone have a picture of the belts, cams and chain in situ in the engine?

it might sound like a bizare request but i know that the exhaust camshaft is driven by a belt which in turn drives the other camshaft by a chain.

in order to understand what's going on it would be helpful to see a picture

my car needs new belts, chain and camshafts so i'd like to fully understand what my "bag of sand"x 2 is being spent on [X(]

Ouch! I got all that plus rollers and the remainder of a 48k service for £1,500. Worth £500 for a trip to Devon to use my fettler of choice?

the £2k does include a full service, new gears for the sunroof and some other minor bits so i don't think its too bad, but it did come as a bit of a shock !

That must be from an OPC surley. I would say thats a lot of money for what you describe.

Belts really no more than £300.
Chain (have no idea abou tthe parts cost but £100 labour would cover it while the rest is getting done say £100 for the part.
The rest is sevice kit and oil about another £250 tops.

So those must be gold plated sunroof gears he is putting in?

Sounds way way too much.

Camshafts are getting on for £900+VAT for the pair, which you missed off. Tensioner rollers are between £20 and £70 each IIRC and you need 5. It's mad not to do the front oil seals while you're in there. Chain and tensioner for the cam chain is over £200 for the all parts I think. Labour for removing the cams and replacing is 6 hours, plus the rest of the service so it's a full day.

Phil - there is an excellent 968 Variocam article HERE

Ignore the variocam movement, and imagine a (much simpler) pair of nylon runners and a tensioner mechanism in their place.

That's as I understand it, but I do still have L-Plates on as far as the '44 is concerned.....

Ahhh missed the cam shafts.. Why do they need done?

£200 for a cam chain, you have to laugh.....

Fair enough without the camshafts the bill would be under £1000 which is more like it.

Slim ~ look at some of the pix in the 968 article above. Doesn't look nice. [:-]

Is this any good?

On a similar subject ~ can anyone confirm the parts required for a tensioner change only?

(Without going into the pros & cons of doing this and leaving the cams / chain etc untouched....)

I should be able to do this myself.....but.... don't have something with me that I'd need (insert "i am an idiot" smiley here)

Looking on the Beryln site ~
THIS is described as the cam tensioner (£32.90)

Is that the cam chain tensioner mech?
Or the cam chain slider block (without the tensioner)?
Or something completely different? [8|]

Thanks []

 

[wedgepilot]

The link in my last post should answer all your questions... []

 

[mik_ok]

Alan - it was your last post that made me think about it! []

I see the $250 quoted ~ wondered if the Berylyn site was highlighting the tensioner or the tensioner "pad".....

 

[wedgepilot]

Ah, I see what you mean... I know Bert's cheap, but that doesn't seem much for a cam chain tensioner. Then again, the pad itself is only about 50p. [] You should give him a call to check, he's very helpful.

 

[Fen]

IIRC Bert sells half a kit so people can replace the easy top pad but not the far more involved (do the cams need to come out?) and less wear-prone bottom pad. OPC is the full kit only.

 

[mik_ok]

So the tensioner has a top AND bottom pad as per the 968 variocam?

Thought from the articles above it was tensioned from the top only (?)

Yes.
968 tensioner has two identical pads, 944 S/S2 tensioner has two different pads.
968 pads both move vertically whereas only upper pad moves on 944 S/S2 tensioner.

It's actually originally a 928 part but they have 2 sets.
