Well just as the title says, I did a stupid move and forgot to not screw the drain plug for the primary case all the way the way in. Well as soon as I started it up I immediately heard that terrible sound, and pulled the drain plug and the magnets gone. Needless to say that wonderful hunk of metal is floating around in the primary. My question is, is this a serious issue that requires me pulling the primary cover apart, or will it just get chewed up by the gears or chain and hopefully mixed in with the oil to be flushed out? And also is there any potential damage to clutch basket for any other internals that would be detrimental? It痴 a 1998 fatboy. Thanks in advance!

 

sounds like catastrophic damage if you start the bike!
The Compensator, primary chain adjuster, primary chain and clutch basket will be chewed up destroying everything in there.
Take it apart.

 

If it was me..... I'd be pulling the primary cover off and finding it.
The magnet will make a mess of the clutch plates, especially the friction plates plus everything else.

 

Drain it
Remove the cover
Inspect everything
Remove primary chain (clutch, compensator, shoe)
Inspect the clutch and compensator teeth
Remove Stator

After thorough inspection order everything damaged new
Re-install

No short cuts.

 

unfortunately I did start it. And I took around the block for a test spin before the thought of the magnet possibly breaking off was a thought in my head, and ironically it was running really good lol. At first I thought it was just initial contact and that was it, but then after some research realizing that the magnet most likely broke off is when I started really getting nervous

 

Magnet is harder than any material in the primary. It will be the destructor not the destructee. Follow instructions from @Rains2much

 

I`m missing something here, you forgot to screw the primary drain plug in, and somehow something is loose in the primary?

And....The primary drain plug is a tapered pipe plug, it does not get screwed all the way in...

 

He says he screwed it in too far

 

Here is all I got to add. Pre-HD for me. A guy I worked with said the same thing happened to him. He said screw it, he left it and said the bike never shifted better than it did after that.
I don't know, just passing it on. It was a late 90s Dana.

 

Nothing good ever came of " f*ck it what can it hurt" with something maybe lose inside a primary. You like gambling big go for it.
