ystrdyisgone Posted December 13, 2014 Share Posted December 13, 2014 Noticed this today as I was finishing up piecing together my 2.5L DOHC. The previous rebuilt motor had this harmonic balancer on it. It spun a rod bearing, so just swapped shortblocks. I'm nearing the end of the race, and curious if this amount of damage could cause issues. If so it's got me wondering if this little mechanical component could have caused the spun bearing?

987687 Posted December 13, 2014 Share Posted December 13, 2014 That won't cause any balance problems, if that's what you're thinking. If you're really worried, break a chip out of the other side, too The dual cam 2.5s spin rod bearings because that's their MO, a chip in the balancer isn't gonna do spoob.

Fairtax4me Posted December 15, 2014 Share Posted December 15, 2014 Won't hurt it any. Make sure the edge is smooth so it doesn't cut the belt. The pulley doesnt really balance anything. Harmonic dampener is a better term for it. Quote Link to comment Share on other sites More sharing options...
