Hello guys

I have a very simple question, will a crank shaft from a 1750 105 Nord engine fit into a 2000 105 Nord engine?

NO, THAT'S COMPLETELY WRONG !!
It does not fit !

But you will have to use the 8 bolt flywheel.
And as well it's not fully correct that it would have an 8 hole flywheel pattern, as late cranks do not have 8 holes any more.

A 1750/1.8 Nord donor crank from a 105/115 or 116 Alfetta will NOT fit into a Nord 2000 block ! as cylinder bore centres from cyl. 1+4 are 3mm different from 1300-1750 to 2000 !!

The only 1.8 crank which will fit into a Nord block comes from a 155 1.8 TS, but has a different stroke !

Pictures shown in next file.

and if its a bosch injected motor it won't have the pick ups for the bellhousing sensors
No, not fully correct.

Series 4 Spiders (90-93) do NOT have sensors for Motronic as pick up at the flywheel any more but only one TDC sensor at the front pulley.

Pics show the differences in cranks 1750 to 2000; 4th (and 2nd) main bearing is distanced out to match 2000's 93mm centre bore between cyl.1-2 and 3-4. Left 1750/right 2000. 2nd pic is 1750, 3rd is 2000. Both show 4th main bearing. All Nord blocks from 1300-1750 share the same centre bore figures with cyl. 1-2 & 3-4= 90mm, but 2-3=93mm

Im glad I opened that can or worms - and really appreciate the feedback on this.

my next question is:

I will consider shipping for those in other countries that can help me.

Do you still need a 2000 crank?

If you still need a crank I have an extra.
I'm in Nevada USA so not TOO far from a port.
Not terribly valuable, make an offer.
In excellent condition.
Can add a pic if you still need it.

Hello to you all.
I dont have intentions to high jack this tread, but herein seems to be knowledge people on the 1750 engine.
Some 30 years ago I had a 1750 engine in a 1967 GTV.
There was noise from the bearing. Someone told me, I could not grain the crankshaft as it was hardened. I would expect in those days nitrated.
Since then I have found out that there was a series 1 and a serie 2 1750 engine .
Then what was the differentiation on series 1 and 2. The only think I have read, some change in the oil gallery.
But then I come back to the old information. Was the one hardened and the other not.
Don’t hope I am asking for to mush.

My memory is not great, but I think the later 1750s had smaller intake runners (ports) than the first ones. I remember searching for a small port head to put on an overbored 1600.

Mr. Eastman,
My memory isn't so great either but I'm thinking the change in intake ports was with the 1600 heads, not 1750s. A 1750 head can be used on a 1600 block though, so that may be what you're remembering. I think the early series change in the 1750s had something to do with piston slap, so maybe the rods were different? I'll see if I can tell from a parts manual if no one else pipes in.

2000 Touring,
I didn't think the cranks were nitrided until the 2L engines. Of course a racer might have had their 1750 crank nitrided when they had it ground. Your 67 GT would have originally had a 1600 engine but it wouldn't be unusual to replace it with a 1750.

Are there any identifying marks on the 1750 or the 2000 crank to tell what is what?

Thanks, Paul

The flywheel flanges are completely different: 1750 has 8, 8 mm bolts retained with "half-moons" while the 2L has 6, 10 mm bolts that thread into the crankshaft itself.

@jay: But only early 1750 cranks do have the 8 bolt flange. Late ones from 116 models do share the same flange like 2 liters and are only recognizable by the different radius shown in the pictures above.

While your answer is generally correct, mine was directed at gt601, who lives Louisville, Kentucky. Since 116 series 1750's were never imported to the US, it is unlikely that gt601 has that model crankshaft.

Thanks Alfajay, I have a buddy who destroyed a crankshaft with loose flywheel bolts by driving it.
We have access to several cranks. I've always been a V6/Alfetta guy so the 2.0 are a little iffy on my identification.

thanks again,
Paul

Still available? Need it for a euro 1975 GTV block (515 code, 6 bolt). I managed to completely fry a race engine with hot driving on a hot day on low oil. Pls pm price. If you have a shop and a web site pls advise link.
