How To Replace a Shift Shaft Seal on a Dirt Bike

[@lindseyott6841]

As a retired automotive tech that is awesome that you made a video like this.

[@lothre]

Thank you, SO very much. I bought a bike project online that had no oil it in. At first i figured the previous owner just didn't finish an oil change. Learned real fast when i added oil that the shift shaft was leaking. found this video and am shocked how easy it is. No need to crack open the case or pay someone to do it, heck, i dont even have to remove the motor from the bike! REALLY appreciate you making this video. You've made my day! Subbed

[@jeffersondalton2023]

Tried this on my ‘99 Kx 125 and it worked perfect. Thanks

[@christsrevenge8030]

Rocky Mountain is bad ass!! Helpful tips and replies to comments! The best! I own one bike and it's a 86 Yamaha xt250 here in Cambodia where most parts are not available so am leaning. These guys here sure help. All I've worked on before were snowmobiles, lawn mowers, grain trucks, tractors, heavy equipment, welder engines, weed wackers , vehicles. Never once a motorcycle but same concepts and designs. You guys sure help a lot and thank you for your work. Somehow stumbled upon a bit of Ronnie mac videos hehe. Drinking beer.

Thank you for checking out our videos! Glad you like them!

@@rmatvmc I'm having trouble with my new shift lever same one in the video. It's a 01 yz250 same steel frame as your 04 in the video. On My old lever the bolt hole is facing the rear but the tusk is facing forward not allowing the bolt to go in.

[@9076723311]

Holy shit! Had no idea you could do it that way. Worked great. Saved my life!

[@mrrrrr1rob590]

Did it this way on my kx85, except I used a pick to pry it out once I drilled the hole. Think I like the screw idea better. Thanks. Now I'm about to try it out on a SXF250 in the next few weeks.

[@chrislane9363]

Don't use the screw method on smaller seals. See my response above.

[@gearedupkim9516]

Thanks for this video! It was Very helpful. I always enjoy Rocky Mountain ATV/MC’s “How to” videos👍

[@robertdonnan8659]

Great stuff, good concise explanation. Gives me confidence to tackle the job. Thanks.

[@kornkultrc]

Worked perfectly on an SSR125. Much appreciated!

[@ericcooper7508]

What do you use to clean it? The spray can. Always looking for a general cleaner that won’t hurt rubber or plastic

[@Ashley-vk7ix]

I was wondering what cleaner you used to clean the shaft?

[@parkmidd]

Great video, do you have one for replacing the Shift shaft entirely? Or could point to a source which can help with that?

[@panzerthetank-fn3gx]

can you put silicone on the seal after? just to hold for a little while

[@tommycabanaw4875]

Well I accidentally clicked video instead of part said the heck with it might have a tip or tricks I didn't know and well it was usefull to get reacquainted with fr80r❤😂😊 I subbed and will probably watch more because it seems like a decent idea to have a better idea of task ahead.

[@GageTcoTEAM2TURNT]

Most helpful bike videos out there!!

[@carloscepeda7240]

Please make a video replacing the shift shaft itself. 💯

[@TreDayImages]

Carlos Cepeda I stripped mine out and need a video bad on how to replace mine

[@MrHoladog]

Perfect it went exactly as you described...thanks...1983 Honda XL125...

[@rmatvmc]

Awesome! That's what we like to hear. Thanks for using our video and letting us know how it went!

[@ML-ks2lj]

This work on a 99 banshee I tried plucking mine with a pick and it just rips apart? Do the seals have almunium in them? I was worried I might be hurting the case

[@gohobby9934]

Shelly ships seven shift shaft seals while Sharon sells shifters. How many times did you have to say "shift shaft seal"? Ha!

[@DirtVibes]

I had to go back and count! "Shift Shaft Seal" was said 11 times, and "Shift Shaft" was said another 7! haha

[@kennethalbert4653]

The torque spec is 7.5 lb/ft, be sure to check your bikes spec....I'll just use this wrench.... Thanks for the vid!

[@carrielee333]

Do i need to drain the oil first? Im working on a cb750 nighthawk.

[@rmatvmc]

If you are unable to lean your bike over or support it on its side then yes, you would want to drain the oil so you don't have oil flowing out while trying to install the new seal. Thanks

[@carrielee333]

Thanks so much. This video was very helpful. I have just started in the last 2 years to work on my own bike and these type of videos are what makes it all possible.

[@rmatvmc]

*Miz Carrie* We're happy to help. That's what it's all about, being able to work on your own bike and keep up with its maintenance. Thanks for watching.

[@jacquesvanderwesthuizen7287]

I've replaced my gear shift shaft seal multiple times now, and it does not want to stop leaking oil. I think the shaft, the casing or both might be damaged. Do you have any recommendations to fix this?

[@rmatvmc]

Its most likely the shift shaft being bent or maybe even damaged enough to where the inside of the seal is not able to do its job. I would suggest inspecting the shaft closely to see if something is not right there. Then I would move onto the case to see if you can find any burrs or anything like that that would cause damage to the seal.

[@geediejones8306]

I have a Cr85R and my gear shift is very loose I tried taking the 10mm bolt out but the gear shift did not come off I was thinking about getting it welded on but ppl say that’s not a good idea just in case it breaks off what should I do ? by the way it’s a 2005 Honda little wheel

[@TheCharillz23]

i just wonder how many times he can say, "Shitf shaft seal." without messing up!!!

[@kevinscripps9839]

Can you use a seal puller on this one or is it different then counter shaft seal?

[@tycewashburn7055]

Umm I dug out mine with a pick and some rubber stuck on it is there a way to get it out?

[@2487Lakers]

Do they happen too leak through the seal? I notice oil from the area

[@tacodog91]

Yes iT tends to be a sign of overheating, the rubber seal expands and contracts and eventually oil will start to leak through

[@sleepyrasta420]

I have a new pit bike only done around 100 miles and i have this problem don't know if its the way I'm shifting and I've broken it or because it's a chinese bike

[@dantecotto761]

What did you lose to spray the shift shaft ?

[@rmatvmc]

We used PJ1 Professional Contact Cleaner to clean the shift shaft. www.rockymountainatvmc.com/parts/pj1-professional-contact-cleaner-p

[@nossrc5638]

Did you know is the Yamaha Badeger 80cc is easy to replace?? Only take the left side out and the seal is there?

[@Captainmorgan1161]

Another great video. Thanks guys

Ive got to do the manual shift shaft on my 2003 rancher 350 es is it the same principal?

Yes it will.

Cool demo im doin some xr 75's

[@chriscardoza9714]

Just wandering if a o ring pick will work or not...?

[@christsrevenge8030]

Chris Cardoza. Am sure that is most common technique yes. Due to the tight tolerances to remove the seal with the common pick you should follow the procedure here. That's why they took the time to make this video available to you and us. Thanks for watching!

[@MPSrg]

Great video thank you

[@Dentinvent]

Well done .

[@rmatvmc]

Thanks for watching!

[@chrislane9363]

Not an advisable method for removing these seals, at least on small bikes like a KX60. I used the smallest screw I could find (#6) and I ended up doing this very carefully, as carefully as possible and I still ended up with scoring on the smooth part of the gear shifter shaft and flattening some of the splines because there wasn't enough room for the screw and it rubbed on the splines and the shaft. I can't tell you a better method but I'm purchasing a hook & pick set and would try getting one pick on either side of each other and pulling evenly on them if I were to do it again. The mention of "you may want to look at replacing it" lol.... well, having to change out the shaft internally, tearing the case down, because of botching a job on a $5 seal, I wouldn't take the risk again. I also ended up putting an indentation in the face where the seal goes into the case be cause I screwed the screw in too far as I couldn't get a good bite with these tiny screws. Damage control and a lot of grease, using a fine sand paper on the shaft to try and smooth and it seems to be holding but man, I wouldn't use this method again. Just an FYI

[@ethanwhite1886]

Sounds like you need more practice 🤣

[@chrislane9363]

@@ethanwhite1886 I've used this method with success on my kx500. I just wouldn't do it on little bikes with tiny seals again.

[@DS2951]

Your lack of experience is really your problem. That's how most people remove and install these.

[@chrislane9363]

​@DS2951 thank you, oh mighty one. Perhaps read my comment again. When the seal is so small on a junior bike, this one in particular, there are better and safer tools to be used than a 'screw.' I'm just advising others to use caution. Sorry your ego and vast experience can't handle that 😉

[@chrislane9363]

​@@ethanwhite1886that could be. Only done it a couple times. But I guarantee you a precision spiral pick (or two) would've been a better tool for the job. I now own a set so I'll definitely try those next time on such a small seal.

[@aaronkenna762]

is it normal for the shift shaft to have about 1ml play moving inwards and out?

[@rmatvmc]

I would recommend checking a service manual for your specific bike but having 1 or 2mm of free play in your shift shaft is normal.

THANKS

[@jacobmathes5688]

Hey where could I get a tusk ignition cover like on this bike I have a 2006 yz250? Couldn't find it on your website thanks

[@dougiequick1]

But if you are smarter? By the time that seal is gone the clutch needs attention anyway ...working on the clutch is the perfect time to change that seal ...yank the clutch cover and clutch basked pull the entire shaft out and then the seal pops out without risking damaging your bike with drill and screw ....the drill and screw I reserve for crank seals which are so much larger and actually worth doing the cheater method ....shift shaft seal? Not so much ....clutches need routine maintenance anyway and THAT is the time to put that particular seal in just for PM ...in my professional (okay EX professional) opinion

[@nico-ee4vf]

Is this why im leaking from this area?

[@rmatvmc]

Yes your shift shaft seal is the most likely cause of oil leaking from that area.

[@joeysteele3933]

Will oil leak out of this if the seal is bad please respond anyone

[@hardendurobosnia17]

Yes it will Just left my yamaha dt 125 overnight with a bad shift shaft oil seal and about 400 ml of oil leaked out

[@naveedaka]

why the expansion chamber have so many dents???

i tried and is not working for the metal seal on my 250 XC

So the problems I have with my shifter is that it’s hard to find neutral and it’s hard to get through gears, each shift never feels the same some click are I have to mush in but almost never do I feel confident in the shift. How do I fix this?

[@joejefferies6668]

Shift selector or barrel going.
