Compensator Torque values

Need some help here. My manual says torque to 100, back off 360, then final torque to 140. Bike is a 2013 ultra for reference.

I am seeing the new spec torquing procedure is to go to 100, back off 180, then to 175.

my conundrum is that I did it to 140 as per my clymer manual and then found out the updated spec later on. I don’t have the cover on yet but it’s been sitting for a couple days now so the loctite has set up. So should I go back in and re-apply red loctite and re torque, should I be replacing the bolt and retorquing with red loctite, or do I just leave it. I haven’t been able to 100% confirm if the T70 bolt is torque-to-yeild or not (unfortunately dealer says they are on backorder and looking like a month out or so before they are in stock again).

I don't believe the T70 bolt is torque to yield. I have reused them. I would definitely remove it and retorque to the proper spec.

That bolt is suppose to be a one time use bolt. 6 bucks buys a new bolt. R&R bolt, clean threads and reinstall to proper torque with red Loctite. You will be able to sleep better at night.

If you don't redo it, you will always wonder.....

Remember, you get what you pay for and information in here is free. I am another one who has used the T70 bolt several times and have never felt any "yield". Harley is concerned (justifiably perhaps) about things coming apart. They specify new bolts in places where they want to be certain that the grade and quantity of locktite meets their spec. I have never had a failure with bolts I have re-used but I clean the bolt and the threads it screws into and add new locktite of the color recommended. I believe the Torx head bolt is unique to the latest compensator and that requires the 175 pound/feet torque. The hex head bolt was 150 final torque.

My 2009 HD service manual states the same thing.
However, with the Screaming Eagle compensator the specs start out the same but instead or retightening to 140, it is torqued to 175Ft-Lbs.
All bikes after 2013 (I think) get the SE Comp.

I am not a machinist, nor do I know at what torue value that T-70 bolt will stretch...

I DO know that Harley, probably for liability issues, specifies some bolts as one time use, when it is only to guarantee the proper thread locker is used...

There are cases where my '01 & '03 Factory Service manuals say to clean certain bolts and reassemble them with (insert color here) thread locker. Those same bolts, with the same torque spec in my '16 Service Manuals, calls those bolts a one time use only..

So to assume the MoCo is only concerned with safety and the "best way" to do things is naive. They are often more concerned with liability and/or marketing.. Remember, the engineers don't run the show, the board does, and they most often will defer to the bean counters....
