Sorry I didn't give it it's "fancy" name. I was taught it's a crank pulley. The fact that it is a balanced rotating mass gives it the inherent quality of absorbing minor vibrations. Harmonic Balancer sounds like Master of the Custodial Arts, still just a janitor... my fault.
I was out at the junkyard looking for interior pieces and came across this dished plate with an offcenter hole in it fit between the timing chain and the cam on an87 or 88. Don't have a clue what it's supposed to do.
On to important things, bearing #1 is spun, all the others look good, but obviously I am doing them all. The problem is I have old style rods. Offset tang on both sides and oil holes on both. I just want to make sure there isn't anything special I need to do. I can just put in a set of the old ones and be good, right? I did a search but didn't find a lot. My concern is brought up since it was touched on earlier the heads aren't interchangeable, are these? Or is this what killed this bearing?
Thanks from the stupid guy in the back of the class.
