Thanks for all the great info. And your right, vibration, pulling of the rear gear, etc, etc will all make for a different ride than a two wheeler. A lot more stress on the rear wheels when turning our Trikes.
I used to work at the Arizona proving grounds for Chrysler when they were located in Wittman, Az. Now they are in Yucca, Az and Harley has more than 15 buildings on the Chrysler site where they do testing. I'll call up an old friend and see if I can "pry" any info from their team leader.....will let ya know.

Thought I would update this thread. Yesterday while I was working in the garage getting my TG ready to go on the dyno Saturday I checked the torque on my dads Triglides lug nuts. The right side was fine and the left had 3 which were slightly loose, didn't take much to make the torque wrench click. This is after it has been on the dyno where the wheel speeds were running upwards of 120 mph on full pulls. I'll check mine after it has been tuned and see if they change any. I think this is periodic maintenance, they need checked from time to time just to make sure their fine.

 

So, you all think blue loctite would be a wise application?

 

It was mentioned in a previous post that doing a torque re-check might move the nut thus breaking the loctite bond.

If I were to loctite it, I probably would loctite and torque the lugs to 100 ft lbs and do the recheck later down the road at 85-90 ft lbs. If the nut moves before the wrench clicks, then the 100 ft lb torque isn't holding. If the wrench clicks and doesn't move, then you're good to go, no need loosen and reapply the loctite. 90-100 ft lbs is the torque range for lug nuts, so the lower end of that scale would be adequate as long as the torque holds.

Though, I'll probably just check mine more often rather than loctiting them

 

Your suggestion is very good. But like you I am just going to check mine more often.

 

Another update. Yesterday I checked mine after having it on the dyno and found 3 on the left side very slightly loose and 1 on the right side. When I say slightly loose I mean they might have been 1 ft/lb below the 90 I torqued them at. I'm not going to sweat the lug nuts, just check them from time to time when I think about it.

 

I had both rear tires off to install the shock extenders. I've ridden about 200 miles since the install. I checked the lug nuts last night and they were still at the 100 ft lbs I set them at. I'll just keep an eye on them to be safe

 

Same here with the install having been done this morning. My Indy friend took em up to 110# on his digital torque wrench. I'm going to recheck them with my calibrated clicker a couple of more times. If they stay set, I'll install my fancy expensive ***** Shiney hub caps (lol).

 

Felt the need to update this thread with my lug nut torque experience. Today I performed the 15,000 mile service on my 2010 Triglide and checked the lug nut torque, they were all still nice and tight. I set the torque wrench to the 90 ft/lbs I torqued them at and it clicked on every one and nothing moved. I also checked my dads lug nuts on his 09 and they also are still tight. They have remained tight now for about 4,500 miles.

 

I've put 3k on since I got mine back and I torqued them down. They have not moved at all.
