Default primary leak.

hi all,

changed the fluids in my 93 flstc last night, the primary was a little wet but i hadn't noticed any puddles under the bike. now it is leaking pretty good. my question is, how tight should I have tightened the plug? i didnt want to over tighten it but obviously I must not have gotten it tight enough.



thanks in advance.

Did you use teflon tape? You need to wrap the plug with teflon or plumbers tape about three times then reinstall. This should fix the leaky drain plug.

do not use teflon tape. there is an O'ring that needs to be replaced on the drain plug.

What year bike do you have? I have a 1998 and was told by my dealer and my mechanic that I needed to use teflon tape and have been with no problems. Did they switch to a o-ring at a certain year model????????

Here is the schematic diagram for the primary on a 98 softtail and as you can see there is no o-ring for my year model or it would have a part number.

On '93,there is no o ring on the drain screw .Correct,use a little teflon tape and leave about 1/8 inch of the screw visible .Make sure it went in straight as it can cross thread very easily...whole nother problem.

After looking at it again last night, the leak appears to be coming from the backside of the primary case and not from the plug. So now im dumbfounded as I have no clue what I am doing.
