This is the best waterpump seal replacement tutorial I have seen so far.
Thank you so much! We're glad it was helpful.
One of the best how-to's. Concise, no B.S.,no irritating background music, and paced just right. I,m off to do this job on my 03 YZ now. Thanks
Thanks for the feedback *Billybob!* Let us know if you run into any questions, thanks.
I'm watching this in Chiang Mai Thailand, after lengthy discussions on-line with my son in Australia. This has solved his disassembly/ reassembly questions that I couldn't answer.
I forwarded the link to him. Now ain't that amazing use of today's technology, a 75 year old guy using your know-how and generosity in the Rocky Mountains to assist my lad on the other side of the equator, all in a matter of hours searching online.
You guys Rock!
Thank You !!!
Another happy subscriber.
That is awesome to hear! We're glad you were finally able to figure out the problem!
@@rmatvmc He reassembled it last evening and took it for a test ride. Came back very satisfied 😁
amazing video,im impressed that you told all the torque specs,really appreciate it.
Very good video! Not a simple man that works only showing you what he does, I appreciate a lot that you explain what are you doing and why so everyone can understand 💪 good job!
Thanks for the great video 👍 .
Not just the sequence but also let me knew the way to remove/install bearing with toools in my toolbox （without special tools ）.
Big thanks again .💪💪💪💪💪
awesome will be my new favorite channel i bought this exact bike and oils leaking coolant leak and idle issues i really need to rebuild ...
excellent vid, just did my '04 YZ250, very helpful
I’ll always come back to your videos to learn how to do my own work. A1 quality.
Strong work! Way cheaper than taking it to a shop 👍🏼 Keep it up - Wes #fixityourself
I'm rebuilding a 1986 YZ 125, started with the air filter that fell to pieces, it's hard finding one, UNI, came through, then the carburetor rebuild thinking it would just run afterwards, I put transmission oil in it, the oil overfill screw was missing, of course, goto put antifreeze/coolant in it and the drain bolt was missing and the casing on the shroud was busted at that screw as well, coolant just came right out lol. So anyway thank you for the video's, it makes it so much easier and helpful. I'm wondering after I get all that back together if it's gonna need a new piston head lol, fingers crossed I hope not.
Damn I wish you guys were here in Sydney Australia!
Just did this on my 2002 Kawasaki kx 125. Can’t wait to ride. Thanks for the video!
Just ordered kit for my 99 kx250 which needs doing
Did you have to undo power valve linkage arm as in this video?
thanks so much , video is truly inspirational, you make it so that it gives people confidence.
where do i buy one of those torque wrenches that you have, its just implanted into your arm right?
Thats the German Brand known as GutenTight
@@db5304 YAH! Ziz ist how vee build zem unt Chermany!
I knew an old Yamaha dealer mechanic who NEVER used a torque wrench. I recommend you do unless you know what you're doing.
They give it to you after you've gained enough experience, rookie.
Cheers guys another great vid👍
Thanks *MaverickDH!*
your the man dude , cheers
Wow that's a clean hammer!!
Awesome video really helpful thanx
Excellent job and very good detailed explaining
First time I myself have had the bike apart yes! And ty very much for the info it was helpful! Now I didnt see to get a power valve gasket in the beginning of the video, and I didnt think about it when ordering the other parts.. but I should replace gaskets anytime the covers are seperated right? If so Ill jus have to wait on the gasket another couple days so I have everything which is no biggy
Hey Rocky Mountain great video! So what I did was this job just now but without a video. I tightened the power-valve arm without holding it in place and as the arm went up it hit the top of the case and maxed out in order to tighten it do I have to pull it off again and check to see that it didn't pop out inside? Also in order to get the gears to line up I used my Kickstarter and slowly push down until the case went flush on if the water impeller moves good does that mean it's lined up with all gears? Any info would help thank you very much!
Would be awesome if you guys did a video of this but with the mechanical seal on a CRF450
thanks for helping!!
Anytime *atvr!*
Brilliant video,thank you
If you need different angles check out my CRF450R Water Pump Repair
Thanks bro.
What other maintenance should be done while the case cover is off? Isn't there an outer clutch seal that can be replaced? I have an 05 yz250 2t
I'm attempting this on my RM 125 in my kitchen right now! 🤙 I have never worked on a bike this is my first one and the impeller broke! I have the case split all new partsand about twenty years of car mechanic experience so here goes nothing haha 😅
Canna_bro_grow 2 Did you get it working?
@@briangonzales5121 yes, i actually did
Canna_bro_grow 2 he’ll ya
Thanks RMATVMC
Glad you enjoyed it *2burning2turning*
Is sold as a kit or separate
thank you good job
please help me,my kx 125 96 is leaking coolant out of magneto cover as well as coming out of overflo tube when started.if u can help great,ja in austrakia.melb,vic
So how do you know if the gears are aligned up properly? Do you just spin the clutch and if the other thing moves it’s ok?
Can I apply this same process to a 2001 kx 125
Suzuki rm125s have a left hand threaded shaft
S Hulse thank you my dude saved my ass
It seems that the Rocky Mountain website doesn't have Tusk water pump kits for Yamaha 4-strokes. Is this true? I have 2016 WR450F. Also, great video. Thank you.
Is it the same on a four stroke
Thank you!....
Great video..but is that definitely the correct way to install the seals...when I changed mine they where the other way from pervious rider
I often use a bolt and washer in the same diameter as the bearings and a nut to force it in
Found coolant in my oil hoping this does the trick. 2015 Yz450F
How do you get the impeller off? I got the bike in gear but I cant stop the tire from turning and I'm turning it so tight I feel like I'm about to snap the propeller off
Very helpful how too !
Appreciate that! Thanks for watching!
I thought so too!
i need a water pump seal repair kit like the one you mentioned in your video. Where to get one? I have a 1989 Suzuki RM250.
Unfortunately we don't carry a water pump rebuild kit for that bike but we do have OEM parts available if you want to check that out for water pump rebuild parts.

I just purchased a 2019 Honda rebel 300. I only put 300 miles on it...After every ride I can see leakage from the weep hole. Dealer claims they did a pressure test and saw no leaks..and a few drops is normal. I don't buy it...A few riders on the Honda Forum are experiencing the same thing...2 of them claim coolant was actually spraying out while riding...Could this be a manufacturers defect with the seals...Dealer advised me that they will not pursue further testing unless they see a puddle.My bike is still under warranty. .What advice could you give me ??? Thanks
I'm jealous of your clean tools lol --- You inspired me to make a ****HONDA CRF450R 03-08 Water Pump Repair Video****
Would you say most water pump repairs are the same?
They may vary slightly, but if you've done one, you can most likely do others pretty easily.
My quad is leaking coolant like a mofo. Is start working on this rebuild in the near future
*Nathan Thomforde* Get that leak fixed sooner than later. Your motor will thank you later. Thanks for watching.
Which grease are u using ??
Hello i have problem with mixing transmission oil with coolant. Is possible that water pump seal now working?
Thank you in advance
YES! One thing I recommend is checking which way you put your seals in. I have a very good shot of how they should look on my channel. Feel free to check it out if you still need help :)
Hello my yz 125 takin water to my clutch case ? Is there any problem with my shaft or something like that i cant find where is the problem.Im waiting for your answers.Thank you.
*Hi Guyz Bro* In most cases the shaft is ok. You can buff the impeller shaft out with a scotch brite pad. Your water pump seals are what normally get worn out and need replacing. If you follow our how to video if will walk you through the process on how to get these replaced. Let us know if you run into any questions. /Thanks
Ciao serbatoio carburante yz250 1998 può funzionare su yz2501999? Grazie 😀
Very good
So I have an 04 cr125, I have milk for oil and coolant running through the engine and gathering in expansion chamber but it's not leaking out of the bike or through the weap hole. Will this fix it? I've never had this issue until now. Thanks
Your head gasket is done for
Hi so I’ve just done this but when I tighten down my clutch cover the kickstart doesn’t spring back but if I loosen the bolts it works perfectly fine i don’t understand the issue could you please help
Will this prevent the bike from running by chance?
What is best type of grease to use
Would u not grease the bearing?
I have a 2005 yz 125 an my impeller don’t have the nut to take it off how do I get it off?
I have a 98 YZ125 and it seized on me because of the plastic on the inside of the crank journals melted and seized the needle bearing on the connecting rod. Does anyone know why this happened and what the plastic is for?
I have milky oily stuff leaking from my breather tube on the left side. 01 yz250 could that be the problem? ?
I had the same problem with my 01 ktm exc 300, replaced the seal, I think it`s fixed
hmmmmm yes that does sounds bad my guy
Lol I was really wondering about the torque wrench that goes that low though... Ive yet to find one that goes below 20lbs and other than that I found a scale torque wrench(ancient) and it even only went down to 5ft lbs?? Where the hell can I find a torque wrench that goes from 0-100ft lbs... I NEED one! If you can point me in the right direction lmk!
You forgot to mention when cle awning the case with anything abrasive to never clean or sand cross ways of the case because any cross ways scuffs or scratching can cause it to leak.
Is this the same step for a 125cc also???
Hello, I’m from Bangladesh.
I’ve noticed coolant dropping off through the weep hole but I don’t have the pump seal to replace now. What if I seal the hole using glue, it’ll definitely stop the coolant flow but will it damage my engine?
Any other alternative I have, because I do not have the pump seal and it’ll take more than a month to bring it here in my country.
Thanks in advance.
probably too late but coolant will still probably get into your engine oil
@@aaroncrain2343 I was thinking of doing the same thing . If the oils side seal is good it should work
Would it make it run bad and not start ?
legends say he is still lubing the center
@rocky mountain ATV MC is it normal for the impeller shaft to have a bit of play back and forth after its torqued?
A slight amount of play in the impeller shaft is normal being they are only supported by one bearing. If yours isn't leaking or making noises, it's most likely normal. You can always check the service manual for your specific bike if it seems excessive.
@@rmatvmc perfect, I had a decent amount of play but once I installed the engine cover on the bike, it was significantly reduced. 👍. Bike is an 09 yz250 so essentially the same as in the video
@@rmatvmc answer I was looking for thank god I went to the comments lol.
Okay. I did this exactly, put everything back together. Found a random O-ring after I was done... looked at every OEM diagram, there's no O ring at this size (3/4" maybe) that I'm missing. I stripped it all down again and checked. Anyone have a tip? I really have no idea where this o ring came from
Make a vid of the O ring and post it on your page so i can check it out. Most bikes are the same. Suzuki are a lil bit different
Hey it might be 2022 but I’m trying to do this on my 2008 yz250 can’t get the power valve blade lined up and in there anyone else have this problem no how to fix it
Can you use engine oil in the transmission as transmission oil?
Yes. And actually, some manufactures like *Yamaha* recommend running a 10w-30 engine oil in the transmission. Thanks for watching.
Rocky Mountain ATV MC Oh wow i didnt know that thank you very much, very helpful videos indeed!! Good job!
Why isn’t my cr85 hitting power bands after it’s just had a full top end rebuild
Clogged exhaust.
Now would be a good time to update the water pump...
curious if this video applies to a wr250f aswell?
There will be some differences but this video can get you through the job on your bike.
@@rmatvmc awesome, thanks dude 👊🏼
Hi, your video helped me a lot, but I encountered a problem. After I put everything together and I filled the bike with oil and coolant, I noticed that the coolant was dripping out from the little hole underneath. What could I possibly messed up?
Edit: I want to point out, the coolant was dripping before I even started the engine, the droplets slowed down after a little while.
I heard some of the kits were defective and leaked
That seems to be my problem on my 06 450 is any different on a 4 stroke or is it about the same.
*SkyView Drone Services* the process is very similar. We recommend you follow your bikes specific service manual and specifications. Thanks for watching!
I did my 05 CRF450R and filmed it - Check it out on my profile if you still need help, Thanks!
Have the same problem, a milky tint to my oil on the clutch cover side, but iv changed the seals, and made sure everything is air tight and the overflow hole seems to be doing its job. However no water seems to be coming out of the hole and water seems to be getting into the oil chamber nonetheless... What can I do? Please help! anyone?
Same
Is it bad if you have a lot of oil inside the powervalve cover where the arms are covered in thick oil?
That's pretty normal if you haven't ever been in there to clean it out. The powervalve gets lubricated with your pre-mix so it should have oil in there.
What sort of grease do we use?
We carry many quality brands you can use. Here is a link to our page. I really like the bel-ray or maxima waterproof grease. www.rockymountainatvmc.com/t/940/Grease-and-Lubricant
Where do you even get those 8mm torque tools for the cover bolts @12:15
We have regular T-handles on our website or T-handle torque wrenches. www.rockymountainatvmc.com/parts/fixt-products-pro-torque-t-handle-p or www.rockymountainatvmc.com/parts/tusk-compact-t-handle-wrench-set-p
what grease do you use?
We used Bel-Ray grease. You can check it out here: www.rockymountainatvmc.com/parts/bel-ray-water-proof-grease-p
What drives the impeller shaft?
It's a piece inside the transmission, I have a repair guide on my video if you want more info
will this work on a 2000 yz 250 ?
You can definitely use this video to help with the water rebuild on your bike.
I have a 03 rm 125 that has milky oil
I’ve learned a lot from this vid
Nothing is leaking but the oil is milky, would it be the same thing?
Yes or it's a head gasket
Don't hang onto the wrench when taking the impeller off, literally just got 4 stitches in my finger because the wrench slipped lol 😆
So do I have to drain the oils do the bike ???
Yes, we had to drain the oil on this bike. You can see that process at 2:05 in this video.
I fill the rads and when a start the engine, it pukes it all out the overflow. Any leads would be greatly appreciated.
It's burping air out of the system, follow your manual for the correct bleeding procedure.
Or its a head gasket
What fat did you use?
What is that grease stuff
That is Bel-Ray Water Proof Grease. You can check it out here: www.rockymountainatvmc.com/parts/bel-ray-water-proof-grease-p
Rocky Mountain ATV MC when doin this do I have to use the grease?
What would happen if i use a water pump that is miss a teeth
Your water pump could stop working and your bike overheat / EXPLODE
The pump on my VFR750 is so different from the pump in this video that the video is completely worthless for me.
*laughs in air-cooled*
thats not called a pin, thats called a punch. smh
