Do I need to make sure the balancer goes back in the same position it came off? I know it has the Hall Effect sensor for the computer, so I'm guessing yes. If so, what is the best way to mark it?

 

Just got a pm from a buddy he said no can go on anyway doesn't matter, if you are talking about the vibration dampner on the front of the engine.

I thought it only went on in one position due to a key way.

 

there is no key way, just 4 bolt flange on the front of the flange, but the sensor doesn't keep track of what position the crank is at, all it cares about is revolutions.

 

for your tach.

Yeah thanks, and so the computer knows when the engine is running to turn the alt. and air conditioning and overdrive, and speedo etc.. on.

 

The only time that you would want to put it back the way you got it is if you have allready made timing marks on it for adj your valve! ether wise it don't matter.

 

your's don't do that already?
Greg

 

Mine don't do what?

 

This is what I really like about this site. No matter how much I think I know I can always learn something here. So I don't need to clock my harmonic balancer...........NEAT!

 

I'm pretty sure your HB can't tell time anyhow.

Thanks guys. The thought of throwing my engine out of balance by putting the HB back wrong has been a blocking factor for me to fix my oil spill I call a leak.... Thank goodness the Cummins is internally balanced! By the way, if anyone is curious, yes I feel completely stupid for not realizing the hall effect sensor is there for rotation and not position. I also feel stupid for not knowing the Cummins is internally balanced...
