Correct. I try to keep it off the threads but I am sure some finds its way there. That's not so bad, the PITA part comes when the adjustor threads are coated with red or blue.

I DID lock them down really tight. Guess I'd better check them for cracks before I readjust them. I got on them pretty hard....

All, I've done a fair bit of research regarding the SE pushrods and can offer the following for info:
It appears the early production non-tapered adjustables were the ones that had some of the lock nuts crack.
The later model tapered adjustables don't have the 'cracked nuts' issue.
What's strange is that some installers use nothing other than torque to lock them down with no issues, while others have them loosen up within a few miles as mine did. (I covered about 35 miles before I heard the first one ticking.)
When I locked mine down I used 3 wrenches-- one each to just stabilize the adjuster and the tube hex, while the third did the actual compression of the lock nut up and onto the tube hex. I'm just thinking-- I wonder if some torque applied to the adjuster section, after the lock nut was torqued would make a difference?
In conjunction with some locktite I'll tighten the adjuster against the locknut as well as the locknut against the tube hex.
I gotta get well first (flu bug) before I can do much of anything.

Update
Standing in the workshop now waiting for the last lifter to bleed down after pulling all 4 p'rods, cleaning them up and checking for damaged ball ends, damaged lifter keepers and cracked locknuts-- no damage found so in it all went again.
I've used red locktite to secure the locknuts to the threads and to the flange faces, and plenty of it too.
My logic is that if they come loose again while I'm on the road I'll call HD Assist to come and get it, and take it to the nearest dealer whose instructions will be to pull the junk SE tapered pushrods out and drop in fixed length OEM's and let me know when to come and get it.....
We'll see how good the red stuff is over next week's rides.... I'm betting it will hold.
If I want to change cams or lifters in future I'll cut these out if the locktite won't let go and get some better quality adjustables....
