Typical crankshaft throw radius?

Typical crankshaft throw radius?

Typical crankshaft throw radius?

(OP)
I have a 1995 Nissan Quest with a V6.
Is there anywhere I can find the dimension of the
crankshaft throw?

If not does anyone know the typical radius of a
6 cyclinder crankshaft throw?

Thanks in advance.

RE: Typical crankshaft throw radius?

Typically crank throws in cars are about 0.5*bore, +/- 15%

When you say "crankshaft throw" you mean 1/2 stroke, right?

Carpoint says that your stroke is 3.14 inches, so your crank throw would be 1.57 inches (39.88 mm).

You might want to double check that figure elsewhere; carpoint is often wrong.

That's awesome!
Thanks so much for the pointer.
That is exactly the info I needed.

Thanks,
Pete.

RE: Typical crankshaft throw radius?

Are you sure you want half the stroke, or do you want the clearance radius of the crank?

Cheers
