Title: Harmonic Balancer Question
Post by: daveh on May 18, 2016 - 03:57:54 PM
Hey guys,

I'm taking some of my 340 apart to replace some things and detail the engine.  I'm installing a new balancer and the one that I took off has this funny pieces on it that sit's up against the timing cover with some type of felt ring inside it (see pictures). I've never rebuilt a 340 only Chevy's.  I know don't kill me.

First - what is it?
Second - do I need it with the new balancer that I'm installing
Third - I have a 1969, 340 I think it's internally balanced can you all please confirm that for me? 

Thanks for all of your help.

Dave

Generally you do not use the felt in the rear of the damper unless it is in a dirty environment such as Farm Equip , so I would leave it out
