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.
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. www.rockymountainatvmc.com/oem-parts/Suzuki

Thanks, Dustin. Nicely done video. You took your time and carefully showed all the steps. Anything different I should know about doing this on a 2000 KTM 250 EXC?

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
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
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 .💪💪💪💪💪
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!
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 😅
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
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.
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!
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
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.
*SkyView Drone Services* the process is very similar. We recommend you follow your bikes specific service manual and specifications. Thanks for watching!
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
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?
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
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.
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
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?
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
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.
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
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
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
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.
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

Thank you so much! We're glad it was helpful.
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.

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.
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
Is it the same on a four stroke
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?
Gaud damn i hate my ktm 200 it is so much worse than this i cant get it
Hello i have problem with mixing transmission oil with coolant. Is possible that water pump seal now working?

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.

Did you have to undo power valve linkage arm as in this video?
legends say he is still lubing the center
Would u not grease the bearing?
Would it make it run bad and not start ?
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 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
Awesome video really helpful thanx
Now would be a good time to update the water pump...
Nothing is leaking but the oil is milky, would it be the same thing?
Yes or it's a head gasket

It's burping air out of the system, follow your manual for the correct bleeding procedure.
Or its a head gasket
@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
