Hi,

I have a 92 ZX750R J2 and since last season I have been riding it with this leak. It is a very slow leak but it its gotten pretty messy and I wanted to finally fix it. Ive located the leak to the red arrow in the pictures. It does not leak from anywhere else!! When I squeeze the clutch lever oil bubbles out of there. Im not sure what exactly I have to do to fix this. I have searched the forum and came across this thread:
http://www.kawiforums.com/zx-7r/88550-clutch-push-rod-seal-help-4.html

and wondering if that the same problem I have. Do I really have to go through all that or could I just remove the clutch slave and just put some gasket maker/silicone sealer stuff and bolt it back on!! Also If I have to go through the whole procedure could some one point me to where I would be able to get the parts in Ontario and exactly which parts I would need. Thanks.

I couldnt get the pics to upload on here so here is a link to another site where I uploaded the pics.

Also I would change the pushrod seal cause brake fluid causes seals to swell and its only a matter of time before it starts leaking.

I took the slave off, but the clutch line is still attached to it b.c i cant get the banjo bolt off! and also how the hell do i disassemble is so that the piston come out and i can replace the seal in there with the new one?? i tried squeezing the clutch but that doesn't do anything. do I have to remove the clutch line to relieve pressure???
thanks

I would've loosened it up first then tighten it back down. The take the cylinder off and start pumping the lever. Make sure you have fluid in the res when you do or youll run out of fluid and the piston wont come out.

hey, finally got the clutch slave all disassembled and the seal was in pretty bad condition!! so ill change that, but was looking at the replacement seal the guy at the dealership gave me and its much smaller in size then the one that came off!! is it supposed to be like that? or did he just give me the wrong one!! also im going to change the pushrod seal but i gotta get the transmission cover and was wondering if anyone knew what size that nut holding the front sprocket is??!! thanks

I think the sprocket nut is a 30mm or a 32mm.

hey,sorry yes i realize its pointless w.o pictures and i meant to take some but didnt get time, so here they are. the new seal is on the left and the old on the right. i feel like its the correct seal and im just stressing b.c this is the first time ive broken my bike down so much and i just want it to be fixed already!! lool.
also is it necessary to replace that spring??? i just bought the seal only! but yea, this slave cylinder seems like cake compared to what i still gotta do which is try to replace those other seals in the transmission case ( which includes removing and re-installing the chain!!) lets see what happens. any ideas on how i could re-use my stock chain as its still in good condition and dont have the cash to buy a new chain!! thanks for all the help!!

I'm sure the chain is fine. Just replace the seals and life is good.
