200 Damper

[SteveStang]

Hi

I have a 200 that I am putting back together and the damper (pulley) at the front of the crank has 2 grooves as where my other one for my 170 only has 1>I need a new one for the 200 as the rubber on the back of it has worn out.
Where can I buy the dampers and what was the 2 grooves for and could I use the single groove one off my 170.

Thanks
SteveStang

This is the best place to get a new one. http://www.damperdoctor.com/Harmonic_Balancer.htm

The reason for the two grooves is that the engine at one point in time proably had an air conditioning unit or power sterring or both and need another groove to run a seperate belt. Usually the two grooved balancers make the engine run smoother. 170 should fit the 200 since dampner doctors have them listed under the same part number.
