Loose Crankshaft Pulley

[daredevil95]

Hi, I have a 86 GN, I recently changed my waterpump, removed the intercooler and intercool small fan on crankshaft serpentine belt pulley. As i was reassembling and i went to install the intercooler small fan onto the crankshaft pulley, the fan connects to the serpentine belt pulley and I noticed this serpentine pulley was loose....I could slide it back and forth about an 1//8" to 1/4" of movement...i don't remember this movement being here in the past? I could be wrong? Motor was rebuilt about 2 years ago and a new harmonic balancer was installed so, Is the movement with the serpentine pulley normal? or should i replace or maybe tack weld in place?

DM sent about a good used RJC pulley I have if you decide to replace ...

You can see a bolt missing from the crankshaft pulley. Better check to make sure you have all of them in and tight. Also make sure the balancer bolt is tight. You'll have to remove the intercooler fan to check it.
