Harmonic balancer question.

First it's called a Crank Shaft dampner, and yes Volvos are internal and thy are a serviceable item. Most shops will tell you thy never need replaced but thy aren't the ones who have to put up with the funky vibrations. Most trucks are fairly easy, just unbolt the old one and put the new one on. The Volvo is much more involved because it's internal.

 

Bruce Mallison(sp) from pitts power has always said they should be replaced..think he said around 4 to 500k? Never looked at a volvo engine. Think most bolt on to the front of the crank. Its less $ than replacing a crankshaft.

I am going on 1.2m still orginal balancer

 

I have replaced only 2 on D13. Customer request. No issues, they just wanted to replace with inframe. They said they saw no difference.

 

I have never seen one replaced cuz it needed it going on 12 years working with volvo have seen a few ISX but never a volvo engine.

 

They wear out, actually the rubber deteriorates and causes vibration issues.

It should be looked at 500K and if they look ratty (the rubber), then replace it.

Most mechanics are clueless.

And it is a cheap fix to a problem that can cause issue for you down the road.

 

well I beg to differ with your opinion seeing as there is no rubber on most heavy use highway engines they are all viscous fluid types with counterweight inside.
