drain plug loose, dealer recomends new pan
I have an 06 FLH and I have the dreaded loose drain plug, and the dealer recommends a new pan. I am asking if anyone knows of an aftermarket pan that is available for the 88TC that addresses the threaded cast drain hole? It certanily is an area that needs to be addressed and instead of installing another "stock" pan, maybe someone has engineered a better one...

if it is too loose for teflon tape t take up the slack,
you go to any auto parts store they will have a self tapping repair kit.
they can be repaired in place, although you must be slow and careful to ensure that the cut aluminum is with drawn- usually by coating in grease
or if you like spending money on a good cause, the baker drivetrain replacement oil pan has a larger oil capacity and solves the drain plug problem you have.
- a steel plug into aluminum, go easy on the torque- the lower end of the range with a new seal will work to seal the oil, it's not under pressure unless a vent is blocked
overtightening will wear the threads, as will cross threading.
when possible start a bolt by hand, turn counter clockwise until you feel a "click", the threads are now lined up and you can tighten as normal

Look for a workshop that can weld aluminum. You can plug and put a new threaded piece or refill the old thread to machine it again. There are many solutions but I would avoid the helicoil that takes 0.050" all around the seal surface.
Castolin Eutectic made an aluminum brasing-soldering compound that could be used in a non oxidising flame; this stuff was fantastic and referenced "21F".

thanks for the many replies
I did give it some thought, but don't like the idea that my oil is being held in my a helicoil. I would not have much piece of mind.
As for aftermarket I can only find Baker and I can't see the money for the additional 1 quart of oil. It's just another cast aluminum pan... Although the additional oil may help on a hot day.
I knew this was coming as I was told a year or so ago that the plug was loose and to expect an issue in the future. Looks like the future is here.
I am leaning towards a new pan and trying to repair the original. Hope I don't need it.
Thanks.

reading between the lines:
is this from dealer oil changes ?
are they cranking the plug too tight and busting up your oil pan ?
A properly installed helicoil or other solution will work, there is no pressure on the plug- and it is not holding anything together.
a welding solution may not work, aluminum is somewhat porous and oil will be all through the aluminum in the pan
#2 I wonder if it would be possible to get a good drain using the unused temp sensor bung, next to the oil pan drain.
it either case you could use the "valve type" drain plugs and never have this again.
i use the fram version on my truck the past 11 years and the brass version on a bunch of my old cars- open the valve, the oil comes out, no stress or strain on the pan threads.
