Question about my crank pulley....need some help
Posted: Mon Aug 06, 2007 10:45 pm
To make a long story short, about a year ago, the pulley bolt got loose somehow and started backing out and I didn't catch it in time, so it wobbled enough to sheer the roll pin in half....I ended up putting a new pin in the sprocket and got a used, but still in good shape, pulley and put that on. Tightened it back up, and used some thread lock to make sure it didn't come loose again. Fast forward to a week ago. I got the car put back together and noticed the pulley start to wobble a little bit after about 10 miles of driving. I never took the pulley off while doing work on the car, only the a/c belt, the compressor, and the alternator.
Anyways, I got the pulley off a little bit ago. The bolt was somewhat loose....it hadn't started backing out, but it wasn't the 130 lbs/ft tight....or whatever the manual says it should be at (I didn't have an air compressor when I put the pulley on from before). Everything seems fine, the roll pin is ok, the pulley is fine, but the sprocket has a little scoring on the outside face. Not sure if it's from the time before or from this time.
Anyways, whenever I put the pulley on and ready to bolt up, I can still rock it the tiniest bit in two directions (opposite from one another). It doesn't want to sit flush on the sprocket. I'm not sure if it's supposed to be like that until I tighten it all the way with the bolt, or if it should sit 100% still even without the bolt (that would make the most sense to me....which is why I think that's the cause of the wobbling). Can anyone remember how tight the pulley sits over the sprocket before you put the bolt in and tighten it down all the way? And if it shouldn't be moving at all, what do you think could be causing it to not sit flush?
Also, once I get everything back together, what's the best way to tighten the pulley without air tools? I need to get it as tight as possible so I can run it up to a shop and have them tighten it with their impact.
