Fiat Dino Forum (FDF)

Hi Bijan,

did you complete your clutch-replacement job?

Just wondering what pressure plate you used? A new one or kept the old one?

Thanks

Has anybody fitted a recent clutch kit from Superformance or Dinoparts? There are two sizes of dowel-pin fitted to the flywheel 3 x 4152287 (about 10.8mm diameter and 25mm long (the parts book shows a lockring on the end of each) 3 x 4111201 (tapered, about 8mm max diameter and shorter) flywheel ske...

I've been buying new parts while the engine is at the machine shop, including a clutch kit (pressure plate, friction disk, throwout bearing) The 2400 flywheel has been re-surfaced - so the dowel-pins were removed, surface re-ground, pins replaced. But...the new pressure plate does not fit on the pin...

Thanks Dario, Stefan, The crank was photographed at the machine shop where it will get opened and cleaned - he would normally send the crank out to the best place in the state for cleaning/grinding, but the journals all look good so we're thinking about whether it needs to go. Therefore the local ma...

and a picture of these plugs (if that what they are?)

Does anybody know the method the factory used to seal the oilway holes in the Dino crankshaft? I was looking at these seals with the machinist yesterday and neither of us has seen that before. Unfortunately I forgot to take a picture. It looks like they have maybe been welded closed, then ground dow...

Thanks Stefan - definitely replacing that pilot bushing! The block and heads will go off to the machine shop early next week - and so after inspection I'll know whether I need to buy oversized pistons etc. From my measurements, it's borderline whether need to re-bore, but we shall see. Which brings ...

Thanks Stefan - interesting theory - i wonder what anybody else thinks. I suppose the force does get distributed to one side as the piston descends, so the pattern makes sense, but I've never seen it before. Next question: I just removed the bearing in the end of the crank (spigot bearing..pilot bea...

The big-end bearings all look roughly like this: Upper bearing worn down to the copper, lower bearing brand new (appearance) big end bearing pair.jpg does that look normal? The upper bearing of the pair is, on every cylinder, the most worn out. I suppose that makes sense given that the highest force...

Thanks to all who have replied so far - i'll soon start asking lots of questions. The head had some bad pitting in the area above some of the large block water openings - but I think it will be okay, I mean, it's not like I can buy a new one... Seeing the condition of that head gasket I'm happy to n...
