Hey guys . Anyone have problems with the rear pulley bolts coming loose? This is on my bro Road King (police addition)
and while riding home last night his bolts came loose and were out about 1/2inch by the time he got it pulled over to check **** out. He has told me this happened once before. I recommend he replace the bolts, (all of but only 3 were loose) and red lock tight.
Any body have this happen or hear of this before. Thanks in advance for any info you may have for me.

 

I've seen it happen before and destroy the hub. I believe someone posted a TSB about it years ago. Check with HD.

 

I would also suggest finding a machine shop that has a set of "go/no go" gauges and check the tapped holes for the quality of the threads.

With the bolts being lose, and having force applied to them via the belt and pulley, they may be "buggered up" to the point they will no longer hold torque, even with loctite.

 

The bolts should be replaced every time they are removed from the pully. No exceptions.

 

Yes, this happened to me on a Dyna. Fortunately, I was going slowly down a road when one of the pulley bolts came so far out that it contacted the frame and stopped me instantly. Rather frightening to screech to a halt for no reason I understood at that moment.

Now, whenever I am cleaning, checking tire pressure or looking around the rear tire I always feel the washers beneath each pulley bolt to see if there is movement. I never did find anything loose on several other Harleys I have owned. Red Loctite is a must when replacing these bolts for any reason. So is a torque wrench.

I change the bolts every third time or so that I have them out. I also use blu not red loctite. Threads are always chased both bolt and hub. Cleaned then torqued to spec. I use a sharpie to put witness lines on the bolt heads (6 o'clock position when viewed with bolt at the top). This is on my 2002 FLH. I have had the sprocket off numerous times in the 17 years I have owned it. No issues. I do visually check the witness lines often.

 

I'll add my weight to the comments above. I have also had one come lose, but only because I didn't replace with new. Clean them threads and use new bolts, they come with thread locker already installed. Be warned, torque them all up pdq - don't answer the phone with some of them only part tightened......
