I am doing a few mods and just finished drilling out my third bolt. It seems that all the bolts especially the allen heads are single use. What's your experience?
The biggest problem I had when stripping fastners was rushing. I didn't make sure the socket was seated or I did not make sure to hold the socket level with the fastner head. The 2nd is real easy to do. You may not be kneeling down to where the fastner is and the socket cocks just enough to screw you so to speak.LIUNARep said:Always using the metrics and the correct size. It just seems that they round out very easily.
If the bolts were torqued over HD spec the threads can damage; then on the way out the damaged threads cause even more damage every turn and eventually freeze up - real bad situation because the only way out is for the threads to go bye bye on the weakest part. Also chemical reactions between different metals over time can cause similar situations. Aluminum is so prone to this happening - thread grease is super important on these parts. Good luck and pray the bolt is the ruined part; but, don't count on it...LIUNARep said:I defintely have a rushing issue!!!! Pardon my ignorance for just a moment but what is this chasing that you guys speak of? Also I have vice grips on what remains of one bolt at the bottom of the lower legs and it still won't budge, any ideas?
The correct tap or die will work to clean the threads. Chasing dies are made to clean threads not to cut new ones.LIUNARep said:I definitely have a rushing issue!!!!

Yep I stripped those out. Get a dremel tool & cut the head off allowing you to drop the bottom axle holder. The remaining stud will come out by hand. Ask me how I know. Take my advice & you will be fine.LIUNARep said:I defintely have a rushing issue!!!! Pardon my ignorance for just a moment but what is this chasing that you guys speak of?

The manual will tell you that they have to be replaced. The front disk brake bolts & sprocket bolts have to be replaced. I'm not sure why. I did compare them to the new ones and noticed that the end of the bolt is concave on the new ones and flat or protruding on the ones I removed.Max said:Maybe not what you mean but yes some of the bolts in the engine are stretch bolts and designed to only be used a single time. Head bolts and the four main case bolts should not be used more then once. They are angle torque bolts that stretch the first time they are torqued. Using them more then a single time can result in improper torque specs.
Had the same Problem.. Stripped 2 allen head bolts trying to put the stupid sissy bar on... I actually found shavings in the threaded side of the base plate Ended up taking a Torx Set to it and hammering it in to the stripped bolt, and got lucky and pulled them out. Went down to Harbor Fake, bought a 40 dollar Tap & Die set, re tapped the Holes, and Re Chased the Bolts, and now its smooth sailing!! You think Harley would have a little bit better quality control :chair:mystic1221 said:I cant take the sissy bar off my base-plate/luggage rack due to a stripped bolt. I just haven't had the time to drill it out. It is a pain in the @$$. Ever notice its usually the last bolt that strips? I was one bolt away from removing the bar. Now my Sundowner just looks weird from the back of the bike since I don't have the baseplate installed.
