My friend hsa an 04 ultra and thought he was taking out the tranny drain plug and mistakenly unscrewed a small alan head screw on the bottom of the engine case on the right side of the case. about a half cup of what looked like engine oil drained out. What the heck was that ??
Thanks

 

Which one did he pull?

 

the one you labeled "primary, 1 of 2. so when you drain the primary with the drain plug on the primary case you do not nee to touch the other one. what is it there for?
thanks

 

This is his primary drain plug. I honestly don't know why the other is there or what it is there for.

 

LMAO..Soos i new that was coming!!!!!!

 

I was waitin' on you rw but you took too long. Another play date with the ol' lady?

 

Yep.you caught me..Never enough play dates!!!! XOXOXO....;-)... ..

 

I believe that was where they plum in the engine temp gauge.

 

It's the drain plug for the crankcase. You pull it to check for sumping. 1/2 cup oil is good. The one to use for your oil temp gauge is the one marked "crank" in soos's picture.

 

did you ever find out

Watt those bolts where. I did the same thing but I can’t unscrew mine I’m thinking it’s for the oil son that sits there in the bottom of the crank case. Maybe you could drain it out that way
