Idiot!
 

So, I'm doing a Trans, Primary and engine oil change.

I finish the primary, move on to the engine oil. As I'm cleaning the oil drain plug and putting a fresh o-ring on, I realize I didn't put a drop of thread locker on my primary drain plug. I torqued it correctly and the HD service manual says nothing about thread locker on either of these drain plugs. But each one had thread locker on them from the factory.

Is everybody putting thread locker on their drain plugs? Should I redo the primary, or am I being overly safety conscious. I am riding two up in a couple of weeks for a couple thousand miles and losing that drain plug would really suck.

Or am I being a complete puss?

I put some teflon thread tape on my drain plugs, never had a problem with leaking, or coming loose.

I use Teflon tape on my drain plugs. As often as you change oil over the life of the bike, I don't think loctite there, is a very good idea. Jmo

All you need is the o-ring, say no to tape or Loctite. The o-ring will seal and prevent any vibration that may loosen the plug.

The use of Teflon tape on pretty much anything that uses a plug will void the manufactures warranty.

You can't get the threads on the case completely clean of oil so I doubt loctite would work anyway.

No, I do not use thread locker. Like other post said no leaks and the o ring will prevent the plug from vibrating loose. Just make sure you use the recommended touqe specs and check for leaks after.

3500 miles so far on a primary oil change. No thread lock or tape. Just a new o ring. Not a drop.

All I have ever done was change the 'o' rings - never put any thread sealant and never a problem.....to each his own!

I use just a new O ring and never a leak. If you want to ensure it, maybe some teflon paste, but no thread locker. There's nothing wrong with a little extra effort in sealing it up.

That's Teflon tape you were seeing. I have yet to ever change the o-ring just the tape for me.
