What is your concern?? Any 670- T engine should have a non-counterbalanced crankshaft in them. That is assuming it's never been replaced with a different crankshaft. Any 1800 RPM gen-set engine has a cheap crankshaft in them because of the application. The best cranks had the small diameter long length bolt holding on the crank pulley. What size socket does the crank pulley bolt take ??

I don’t have them in my possession yet , was just checking to see if the cranks were the same as the N5. Both of these engines were stationary rigs. Gonna stroke one of them for a big cube class and convert it to gas

They are not an N-5/6 crankshaft as I see it. If they have a fluid vibration damper they are the counterbalanced design. Never have seen a rubber damper on the N-5/6 crankshaft.

Say Dr., will the fluid damper work on a non counterbalanced stroked crank?? It has been computer balanced. |

It will work fine. I've had one on a 180 twin-spin puller for many years.

Can someone help me? I am looking for a standard size crankshaft for an Allis-Chalmers 670T motor. Can anyone recommend someone who might have it?
