Oldsmobile/Buick Repair: 97 buick riveria, buick riveria, harmonic balancer puller

Question

Answer
Hi
You'll need a harmonic balancer puller and 3 (1/4"x28x4") (Quarter inch by 28threads per inch by 4inches long) bolts to screw into the harmonic balancer.
The bolt holes are VERY SMALL and are USUALLY NOT centered in the access holes on the balancer.
Use your flashlight....you'll see the small screw holes in there for removal of balancer assy.
Other that that, it is pretty straight forward.
I Hope this helps
