Hello, my name is ***** ***** I'm here to help get your problem solved.
There is supposed to be a washer behind the bolt, is there? Was the loose pulley causing some type of other problem? I'm just trying to figure out exactly what is going on and why you are messing with pulley.
Not sure if you seen my original reply so I'll copy/paste it.
Were you torquing bolt down before? Have you inspected threads on bolt?
The grooves would be worn in pulley because of bolt coming loose so that shouldn't be a problem.
By in and out are you saying you can fully insert bolt without even tightening it? Just by pushing it in? If so, something is definitely stripped.
Ok, that is fine. Also are you torquing bolt down when tightening it? If it was stripped it wouldn't torque down.
Even a electric impact probably won't get it tight enough. There is also a key on crank gear that fits into crank pulley, is the key still there or did it break off?
There is a picture a new crank gear, you can see the key/knob that sticks out which goes into hole on crank pulley. Is the key/knob still on gear or did it break off?
If all looked good then I'd recommend using a torque wrench to torque bolt down to 135 ft lbs, nothing else should need to be done. You could also add some loctite to threads but that shouldn't be needed. Let me know how it goes or if you have more questions, thanks.
Keep me updated, thanks.
Yes that shouldn't make a difference.
Sounds good, let me know how it goes, thanks.
If it wobbles then I'd recommend replacing pulley and spacer, the wobbling could cause enough vibration to eventually make bolt come loose again.
Happy to hear its nothing more serious like a stripped bolt or crankshaft. Let me know if there is anything else I can do to help, thanks.
