Z400 oil leak/seal question

[2_DONE_THE_TON]

hey guys!

my gal is leeking oil behind the sprocket.so i bought these parts to remove the leak.


my only problem is how do i come trough to the oil seal in the back,it seems like a need to remove the black rubber thingie in front to reach it.
how do i remove that?do i need to cut it out and buy a new one or is there a simple way to pop it out?

If I understand correctly, you bought all the parts on the white paper to stop the leak; what you needed was the sprocket shaft seal, which happens to be the rubber thingy you're looking at.

+1 and the clutch pushrod seal in front of the output shaft is discontinued.

Hence the apparent liberal use of RTV, which is just as good 8)

ok guys:

1.)what does rtv meansorry im not a native speaker.
2.)so you mean that i need to replace the black seal on the sprocket and clutch?
3.)how do i get the seal out?cutting it?

 

[Rich Ard]

It means Room Temperature Vulcanising Silicone. Redliner was being facetious, I hope; it is not as good as the original seal.

 

[Rich Ard]

You would get it out with a pick or a seal puller.

RTV is the silicone gasket material in a tube you get at the auto parts store.
A difinite no-no. Use three-bond,yama-bond, Kawa-bond, all the same grey
colored semi-liquid for use on bikes. RTV will break off and clog oil and fuel
passages.
The clutch seal is no longer made. So it would be very difficult to locate.
To pull the counter sprocket seal use a big s screw driver and pry out the seal.
Or buy a seal puller at you local parts store. It will be a flat bar with 2 different
hooks on one end.

thanks guys...so it seems like i need to remove that clutch seal mess and find another solution...
is there anyway to diy a clutch seal if this party is not available anymore...

thanks guys for the help!

Are you kidding? I've seen entire bikes built with ZERO gaskets, all replaced completely with RTV! Uh...then again, they do end up coming to me for fixing...hm...

Oh, if you're having a hard time, these seals have a layer of steel inside them. Take a drill and VERY CAREFULLY drill about a 1/8" into the seal. Then take a self-tapping metal screw and screw it into the hole. Take a claw hammer or crow bar and pry the seal using the screw. I still haven't bought a seal puller and make it by just fine :

I would argue that method to be asking for further problems.

Yup.

Do it right. Redliners way will work if need be, but why half ass it (as Red seems to love doing ??? )?Spend the money on a proper seal puller ($20 US).

 

[2_DONE_THE_TON]

just went to my local kawasaki dealer....he didnt even have an idea that there is a seal right there...till i showed him a pic of my messed up seal.
he´ll give me the number of a company that makes custom seals(guess that will be pricy...)

i wont spend 20 dollars on a seal puller.ill make a diy one

 

[HerrDeacon]

Sounds like my local Kawi dealer. I quickly learned to go in with a part number or else I wasn't coming out of there with the correct part.

 

[Rich Ard]

Looks like it's still available as part no. 92049-1506; go to motogrid.com/p/OEM-PARTS and check it out, but you should be able to walk into any dealership and have it the next day or two.

Yes, the output seal is readily available. I recieved 2 just the other day.
It's the clutch pushrod seal that is discontinued.

Ah - beg pardon!

 

[2_DONE_THE_TON]

...or the like. They may be able to source one if you can provide measurements.

If the seal still soft it is reusable. If not one can be made. 'Seen it on the internet'. A valve stem seal
was used in a home made plug. I think it was on KZ400.com's website or KZRider.com . I'm putting
a 440 back together right now. The seal I have is reusable. I do some measuring today and report back.
