Mine broke at about 23000 miles last summer on a road in LA on my way back from OK headed home to Atlanta. It happened on I-20 just at a dealer. I hobbled there in first gear and they had me fixed and back on the road in less than an hour, under warranty.

Have you done periodic maintenance and torqued the bolts to spec? That is the only good reason for these to fail or fall off. By NOT tightening them when you service your bike

I'm not quite understanding where this problem is. Anyone have a pic of the spot where it's happening? Is this a problem with the shift levers or the shaft they are attached to? Is the replacement part any better than the original one? I checked my shifters and the whole assembly seems to wobble a bit. Not sure if that's normal. This would suck if I'm out in the desolate desert on a 110 degree day. Lots of times I ride these desert back roads and don't see another vehicle for 35 miles or so. I can see the buzzards circling already.

My best guess is that the bolt is being over torqued at the plant, causing the threads in the center portion of the bolt to be pulled against the valley floor and flattening them, then over time the through vibration and use the lever begins working itself sideways allowing threads to side over splines.
They should use a stepped bolt, not a full length threaded bolt.

Not true in my case - unless of course the dealer did not check the torque when they serviced it before they sold it to me...

Yep, mine went out somewhere around 20,000 miles and repaired under warranty. HD did publish a bulletin changing the torque specs, but that only updates the dealers. Service manuals will never be changed.

Mine had nothing to do with torqued screws. The spline on the inner end of shaft stripped. It would not grab the shifter linkage arm. Dealer had no time to help me for a couple of days for a ten minute job. I'm sure it's made from softer material than the shifter shaft on my 08 which had 100000 on it when I got rid of it with no problem with shaft. It is a nusance when it fails.

My splines were stripped out on item #15. The bolt was still tight.
