Been fighting a belt high pitched “whine” under heavy acceleration and now a chirp that has turned into a squeal. The chirp/squeal is before it gets warmed up. I have cleaned all my pulleys, all pulleys look perfect in alignment, and gave a new belt to put on.
question is, with no belt on, and in neutral, should I be able to move my crank bolt counter clockwise/clockwise maybe a 16th of an inch with my fingers?
Ahh, no since the balancer is a interference fit with no keyway to hold it in place if the bolt is that loose the balancer is probably slipping on the crank. Not a good situation
It’s not like it’s loose to where I can screw it out. It just rocks clockwise/counterclockwise a tiny bit, maybe a 16th of an inch. I can get a wrench on it at an angle just to see if I could loosen it but it wouldn’t budge. Of course I didn’t have enough leverage but if it was loose it would have unscrewed I would think. I’m going to retry once I have the belts back in and in gear.
thanks!

If the stock bolt is loose in any way it must be replaced - it is a torque to yield - there is NO retightening.

Are you moving the bolt AND the inner hub of the balancer? That's a real no-no!! I would pull the rack, and try removing the bolt. Something is very wrong. Can you see the headof the bolt? If it's a hex headed cap screw, it's probably the stock bolt. If it's a black headed 12 point headed bolt, probably an ARP. Either way, you need to get this resolved-SOON!!
More to the story. After I got the new belt on and cranked it up everything is nice and quiet now. However, I can now, with my fingers, rotate the bolt left/right almost a complete revolution. I imagine if I could get a socket on there I could continue loosening it. Harmonic balancer is on there solid. Having it looked at in a week or so when I can get it in. Going to do a cam at that time as well.
thanks for all the responses!👍
