8N--LOUD VIBRATION
I have a loud vibrating noise coming from the front of my 8n. It usually occurs when I am messing with choke or accelerating. I have not yet changed the oil and it probably needs one could this be the problem?

Perhaps a water pump bearing or maybe generator bearing?

If you can't fix it with a hammer, you've got an electrical problem.

Wiggle the fan, look for end play in the shafts. Loosen / remove the belts and turn the shaft. Feel for roughness as the shaft turns. You should fee no noise, looseness or grittiness as the bearing turns and there should be virtually no end play in the shafts. And definitely no side play in any of the shafts.
If you're careful you can use the poor man's engine stethoscope (long screwdriver) to help pinpoint the noise. Just be careful around moving belts, shafts and pulleys.
An out of balance fan could be a source but if the fan is truly out of balance, there will likely be some obvious play in the fan shaft from excess wear.

Place the tip of the screwdriver at the point where you think the noise is originating. Then place your ear to the end of the screwdriver handle (direct contact). The closer you get to the source of the noise, the louder the sound will be. That's why I say be extra careful. You don't want anything to slip and end up on a moving surface. It'll ruin your day if you have to pick screwdriver out of your cranial cavity.

I started up the 8n yesterday and ran it for awhile then drove it. It only vibrates when I accelerate beyond the 1/2 way mark on my accelerator. It doesn't seem to do it in 4th gear. I checked the fan and pulleys as suggested, they seemed okay. I have not check the bearings yet. Brent-- I do not ahve a loader on it. Also, BigDog-- it has an alternator but I'll check the waterpump bearing.
