Fiat Dino Forum (FDF)

Hi. everybody! I think I know what the discussed "fuse" is for. It is a safety cut-off switch, according to the Fiat original spare parts list (no 4235474). In the wiring diagram it has no 73. It is supposed to protect the vacuum pump to break down in overheating, caused by a leak in the v...

Hi again, Tobi. My 2 litre Spider is from the second series, but I can assure you, the fuel pump in my car is never activated just by turning the ignition on. Before I installed my "by-passing switch", I had to crank the engine for quite a while until starting, if not driven for longer per...

Tobi; I was surprised reading you comment that the ignition switch overrides the oil pressure safety switch - I have now checked my 2 litre Spider electrical diagram to see how the wiring is done. As far as I can see, the ignition switch has a separate wire (blue/black) running from the ignition swi...

Congratulations to your Dino ownership! Concerning your question about starting problems; In original, the Dinos have a engine oil pressure sender, situated at engine´s right side (together with the ordinary oil pressure gauge sending unit) - wired to the special fuel pump electrical relay. This is ...

Dino John; Your chassis number plate with number 0466 stamped - it is not a colour code - it is the Fiat spare parts number (according to the description of the chassis number plate in the original Fiat Dino spare parts catalogues). The third number 4954 should be a homologation number, but I guess ...

Beanderb4; I feel we have a small missunderstanding here - If you have the 40 DCNF carburettor versions WITH air flow adjustment needles on your car, you are able to balance the air flow between the two different venturis in the same carburettor. This is to be done with all three carburettors, obvio...

Hi. Yes, you are absolutely right! The first version of 40 DCNF has no air by-pass screws, and I think the same also apply for 40 DCNF 6. On 40 DCNF 12, you will find
extra air by-pass adjustment screws. (On the early 40 DCN 14 carburettor, you will not find these, either.)

Re the discussion why the front coil springs hit the front tyres, when car is jacked up; My experience from a 2.4 Coupe, which I owned in the eighties´ (why did I sell it?) and a 2.0 Spider is, that this is a question of tyre dimensions. On the 2.4 Coupe - with original 205/70/14 tyre - the springs ...

Re the upper and lower front ball joints; Yes, you are right, the original parts are riveted to the upper and lower Control arms. You have to drill out these rivets to exchange the ball joints. The original Fiat part number for the upper ball joint is 5969335 and the lower ball joint is 4355787. As ...

Answering your question re 2 litre Spider rear brake discs; If you have a Dino with standard 5 wheel studs system, you must withdraw the complete drive shaft with outer bearing from the rear axle tube. This should be fairly easily done without any special tools, as the outer bearing should just slid...
