Hi I wonder if anyone can help me with my problem. I have a 90 Bonneville
3.8 ltr with a separated crankshaft pulley damper. My question is, are all
GM 3.8ltr pulley dampers the same, my local GM dealer wants $495.00 cdn for
the part and so I was thinking of going to the wreckers and pulling one.
Also if I find one does anybody have any tips for removeing the old one,
i.e. does the bolt undo to the right or left, I think it's to the right,
would I need an air impact tool to undo the damper bolt seeing as it has so
much torque on the bolt and I have no way of stopping the damper from
turning from the rear of the engine.
Thanks for any help.
Les Cox.

$184.60 was the list price ( USA ) at the dealer for my 91 back in
January of 2005.

You might get a better deal at an auto parts store.

A salvage yard may yeild one in good shape. Slip the serpentine belt off
and put two hands on the harmonic balancer pulley and try to spin it or
move it back & forth. It should have less then 1/16th of movement. Also
inspect the rubber for cracks. Afterall your talking almost 16 years
old. When my mchanic removed mine the bolt broke loose fairly easy for
never being touched since it left the GM factory. I'm not sure about the
right hand - left hand thread.

My harmonic balamcer broke loose on the driveway on New Years eve about
5 pm, so I was stranded for afew days at home

The yard should be able to help out with removal of the part if your
unable to do so.

Good Luck

Std thread, but not all years are the same, the salvage interchange book or
a parts store can tell you, also try gmpartsdirect.com
