Works best with a air impact tool. There is room.
need more info on what your question is, is it how to remove?
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.
its located behind the harmonic balancer, you must have a special tool to remove it. then there are four small screws that remove the cap.
Right
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
Use a harmonic balancer holding tool DenLors 648796 to keep the pulley stationary while loosening the bolt.
behind the harmonic balancer
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
It could possibly be reverse threaded (right to loosen, left to tighten).
on a 1994 it's behind the harmonic balancer
