Kawasaki Ninja 250 Shift Shaft Seal Oil Leak Repair 

For the most part, the world is pretty nice! I’m pretty sure that your 650 will have a very similar repair technique. You can always post back here if you need guidance. Ride safe and have fun!

Jody Valentine it’s a pretty common issue, hope it helped you out.

Glad it helped. It’s a little bit of a pain, but doesn’t require anything special so just take your time and save big $$$ over taking it to the dealer.

I cant seem to find where to buy this seal for my ninja 300 where did you get yours

It’s a pretty common issue, parts are cheap but it takes a bit of time and patience to do it. Best of luck!

Always great to hear that my video helped solve an issue. Thanks for watching, ride safe!

Alecxix Fernandez hope you’re able to get your bike fixed, thanks for watching.

Tom Smales thanks, couldn’t send the bike out of my garage with a leak like that.

@@TomsTinkeringandAdventures your a good Tom..

mike 64 thanks for watching!

mike 64 thanks for watching!

@@TomsTinkeringandAdventures Hey Tom can you do that with a tutorial on how to do dinner water pump seal and how to remove the fan on the water pump thank you

Brad Bishop if I get another ninja 250 in the garage....

Hawkeye Pierce I’m gonna assume you were able to fix your bike?

Tom's Tinkering and Adventures I sure hope so! I’m taking it apart tomorrow , but it definitely looks like this is indeed where the leak is coming from alson you said it was common amongst these bikes so we’ll see! 🙏🏼

Tom's Tinkering and Adventures if you have time and it’s not to much trouble would you be able to send me the link where you orderd the part lol it would be of much help! Thanks 😊

Hawkeye Pierce I can’t remember where I got it. Likely EBay? Google search Ninja 250 shift shaft seal, it will come up.

Tom's Tinkering and Adventures thanks man I appreciate it

Thanks for watching!

Freezing the seal is a good idea and something that I probably should have mentioned. I don’t usually put sealant on the outside diameter unless the manual recommended it, a bit of oil or grease is fine for lubricating it to help install. Thanks for watching!

Cool, thanks for such a speedy reply! I think I’ll freeze it but do minimal grease - that seems strange to me, like it might push back out, no? One more question - is does the case have a collar on the back side that the seal will fit flush into, so you know when to stop (gently) hammering?

@@sveensvensvn yes, there is a lip that it seats against.

I would assume so, but it's always best to just do a quick check online.

@@TomsTinkeringandAdventures thank you sir, and yes it the exact same part.

Jonathan ayun most of them are similar.

@@TomsTinkeringandAdventures for some1 that know ye my oil seal is on the clutch lid...

Jonathan ayun most can be pulled out like in this video.

Og Vonniee you do?

I don't see were the lack coming from

Og Vonniee the leak on mine was from the shifter seal.

Yes, that cover is so access the flywheel bolt to turn over the engine. If it’s locked up though, you’re going to have to disassemble the engine and rebuild it.

@@TomsTinkeringandAdventures There are several video's of guys gently working this crank bolt back and fourth on bikes that have been sitting for years after they dump pb blaster, brake fluid and such in spark plug holes to penetrate the stuck pistons. If there was no engine damage and the pistons are frozen from just sitting, theoretically it might work. I think i will try it. My thinking is clockwise with gentle pressure, no leverage beyond just choking up on the ratchet. Counter clockwise would start unscrewing the nut, i think. The guys who do these video's say they have great success doing it. Your decision to fix the leak was very nice for the new owner. I think i would prefer to have bought a used bike from you over buying one at auction like i did. Thank you for responding and giving me your thoughts and insight!

@@freemarketjoe9869 yes, I have seen people get engines unstuck. They might start and run, but they are rarely long for this world! 😀 It’s worth a shot though, best of luck and please let me know how it goes. Take your time, you may be one of the lucky ones.

I have seen it happen to other bikes. I have to look, I have some parts remaining from my ninja 250 days.

No idea, it was a non running super cheap bike that I bought, got running and fixed the major issues (like this leak) and then sold for a very meager profit. If I had installed new chain and sprockets, that would have added to the sale price so I let the next owner install whatever kind of consumables they would like.

I’m currently looking at fixing my ninja zx6r smashed the flywheel and stator after an accident but yeah I get what you mean :)

@@garyrenwick2706 I have seen the exact same thing. When I sell a bike that needs consumables (tires, chain/sprockets, etc) I always let people know. I could buy the super cheap set on Amazon and install them, but perhaps they want the top of line stuff and it would be a waste of my time and money. Good eye!

Alex Crichton I have seen them for $500-$3000 depending on age and condition. A good one for $1300 is a decent deal. It really depends on your area, bike sales are very location dependent.

Tom's Tinkering and Adventures Thanks man!

Alex Crichton let me know what you decide!

I think I ordered it on eBay, you can get it at the dealership as well.

@@TomsTinkeringandAdventures thanks for the quick reply. Is it called shift shaft seal? I tried to look it up but couldn't find the exact name? Thanks

@@honluu298 that’s what it’s called. Might have to do a bit of research but it’s available. Fits a lot of different bikes, was less than $10 if I remember correctly.

@@TomsTinkeringandAdventures i really appreciated your response. I check the manual I dont see any oil seal mentioned on there. I have 2019 ex650 abs model. Do they have a different name for this model?

@@honluu298 look online at a parts fiche, there are lots of sites that have them. Might take a bit but you will find it there.

yancey chew try 92050-082

Tom's Tinkering and Adventures thank you I’ll check it out

@@TomsTinkeringandAdventures This part number is for the all rubber seal, will this still work in comparison to the one with metal on the outside ?

Blake Douvros it should have a metal outside diameter if it’s an OEM part.

Travis Cole it’s metal on the outside with rubber in the middle

I highly suggest checking out an OEM parts breakdown. You can also search “Ninja 300 shift shaft seal”.

@@TomsTinkeringandAdventures found it thanks

I usually order OEM parts from Rocky Mountain MC, but I think I got this one on eBay?

@TomsTinkeringandAdventures what was the item number on package it came in?

@@scottyboySBS I’m sorry, I don’t have the information anymore. Rocky Mountain has the online parts breakdown and you can find it there

It’s common. Keep watching, change it when you’re ready! 😂😂

nikita bradley could be water pump seal or head gasket. Both are not too difficult, water pump is obviously easiest because you can see how to remove it in this video

Well I guess that would have been a nice addition! I guess next time, thanks for watching.

ShawneeGuy Man indeed it is!
