Right
need more info on what your question is, is it how to remove?
The most common reason for the harmonic balancer breaking on a 1994 Pontiac Bonneville SSEI is the inner and outer mass is breaking the balancer down. This happens because your engine is running rough or too high of RPM's.
with a balancer puller you will need a balancer installer also a hammer of any kind is never ever needed
behind the harmonic balancer
yes
I tried to change the harmonic balancer of my biuck lesabre 1994, but i can't remove the old one, the bold in the center is very , very tight and i don't know the type of screw, right or left turn.
The harmonic balancer is definitely NOT a lifetime part and can and often delaminates so that it starts squealing on cold start even after 80K miles on some Jaguars
You could find it at the dealer, make sure you use sealant so as oil doesn't leak. while at the dealer find out what the torque spec is.
on a 1994 it's behind the harmonic balancer
it doesn't have a belt it has a chain and it is right behind the harmonic balancer
Works best with a air impact tool. There is room.
