Mechanical Seal?

Ok ..got my bike all back together.. did carb cleanup and tank repaint.

got it all finished and drove around the block couple times and seems to be running fine!!!

then noticed some antifreeze leaking.. Guess that was from the hole earlier in my other thread.. After reading the manual it is from the "right crankcase drainage outlet" It's some sort of mechanical seal? Crap.. Drain bolt isnt loose. Is this going to be bad?

Is there a gasket in there between the plug and the engine block? Or do you remember noticing anything funny when you pulled the bolt out? It maybe stripped - or it maybe (fingers crossed) that you didn't put enough torque on the bolt when you reinstalled it. Given that there was no leak until you took things apart, I'm guessing it's nothing at all major - go through your steps again (well, in reverse from when you pulled everything) and see if something looks "off."

I checked the online manual and reportedly there are gaskets associated wthi the various drainplugs; check those, but also check your torques (8.8 N-m) on the plugs/ THere is an additional caveat aout the mechanical seal on the water pump impeller, but it seems odd that that would suddenly start to act up.

When you refilled the coolant, did you bleed the system thoroughly of air?

Well the thing is I only drained the oil, cleaned carbs, painted tank-fenders. I never drained the coolant. Put it this way.. its probably not a new leak.. I noticed this when I first got the bike last year, but I had to replace R/R then it got cold and did the carbs and such.

I am just guessing the mechanical seal is going bad. since antifreeze is dripping out the weep hole. Is it that bad to remove the right engine cover?

I had a slight brain fade and realised a slight mistake and edited this post
Sorry for the confusion.



Did you notice any coolant in the oil at all?

That post has been edited.

I was thinking of the bearing, not the seal.
So sorry to have worried you on that

next dilemma I see is.. there are 2 dif part #'s. ahh I see now on kaw site the 1052 is superceded by the 1057.

Ok tore it down last night.

Followed the manual mostly

Pulled right exhaust cover, unplugged brake switch, unbolted ear, unbolted radiator cover, removed lower radiator hose, and 1 mounting bolt, pulled the exhaust out and swiveled it down to floor, unbolted the subframe-6bolts, Presto ready for removal. So it looks like prior to me getting it the bike might have sat for a bit.

Looks to be a good thing you got in there when ya did.
Hmm, maybe I'd better check what my waterpump looks like while I'm changing my stator !!


Great pics
