Hi
It looks like Im missing a bolt in the middle of the compressor pulley.
The AC still work.
Is this bolt critical?.
Anyone know what type it is or even if it can be replaced?.
Thanks
Micko

 

Yes critical and should have caused some problem by now It appears to have been missing for some time and clutch may be rusted so badly to splined shaft it's allowing AC to still work. Once/when bond breaks loose if issue not addressed you'll likely be wishing it had.

Bolt retains AC clutch to compressor shaft and shims for clutch adjustment.

Thanks for the quick reply Number9.
would driving with the AC off be safer?

 

If it's worked so far, it's got to be stuck on there pretty good. The only thing I would worry about is the clutch hub falling into the fan or something like that. Turning it on pulls the hub towards the compressor. But then it kicks on and off as it runs. Maybe just use it and find a bolt as soon as you can.
