Thread: Harmonic balancer

The ross balancer is slightly smaller than the OE or Dayco balancer my mechanic found that the 7PK1800 serpentine belt was a touch to big the tensioner bounced around to much a 7PK1790 fits great this is for a non ace car but drop 10mm for ace car would be the same.

Pays to check, for sure. That thing lets go and it's new trans time.

I went to do mine today but my socket that fits the 3/4" torque wrench is a deep impact socket, no good with the engine in the car, and radiator. Until next weekend. I wonder if I will have this fan belt issue, my belt is new so might not have stretched much yet.

Yeah, the last time I looked when dropping in the new engine it looked good, maybe all the new torque killed it but chirping deffo is the sound of it going!

Yes those are scary when they let go I had just been driving at 100kmh a few kms before mine let go. Thankfully it let go at like, 5kmph. Just leaving traffic lights. In the centre of an intersection. Car would not move as the fallen drive shaft was wedged. I couldn't get out safely being in a wheelchair.
Raa were extremely fast, got the broken driveshaft out and I was then able to drive out of the intersection.
Truck home as did not want to drive the 50km home with only 1 driveshaft.
It marked thr transmission, and had not been barely moving, it would have been nasty when it broke.
I have photo somewhere of the state of the drive shaft. I'll try find it
