Dude, this video couldn’t have been done any better. Straightforward, very detailed. Made me feel way more confident about rebuilding the water pump on my 450r, and I had great success today. Thanks!!

@TheCopyKeyboard 5 лет назад

Cote, Thank you for being a straight to the point motorcycle repair guide! I made a video on my CRF450R because you inspired me!! Thank you for the help

@TheCopyKeyboard 5 лет назад

I just made a video like his on my 05 CRF450R. Feel free to check it out and give me your real opinion like you did for this guy.

@harrypwatson 8 лет назад

Also the audio cut out half way through. How tight do you do the WATER PUMP GULLER (the fan part)? Great video! Quick to the point, simple clear. saving me lots of money! Thanks

@wernerschaeferling4900 5 лет назад

Very helpful I have a 2002. Cr250r an put it together an it was leaking out the weep hole, looked at partzilla for seal installation and didn’t really help me, watching your video I realized I put the out side seal in backwards, going to order a new shaft due to it being shiny were the seals ride, thanks keep up the good videos

@coloradodirtbike5930 7 лет назад

video is great really appreciate the help. thanks

@shawnp8429 9 лет назад

I will skip the pump go with bigger rads . thanks for the quick response definitely appreciate it

@HOTSHOT-ls1bc 7 лет назад

not sure if he says it but make sure you put grease around the oil seal AND MAKE SURE IT GOSE ALL THE WAY DOWN AS FARE AS IT CAN I had to remove my bearings because it was rubbing in it and I just ordered a new bearing and oil seal

@garretthouseknecht7851 7 лет назад

Thank you. This video worked great for me. You may want to add to remove the kickstart also.

@garretthouseknecht7851 7 лет назад

I know it should be self explanatory, but some may not know.

@hugohugo2256 5 лет назад

What to do when the propeler does'nt have the nut to put the wrench on ?

@xdwaynex4849 9 лет назад

nicely done

@mikedews7216 3 года назад

Thanks man! Need to go back to dealer n buy gasket 😖 unless I can just change the violent seal from the outside?

@CoteMotorcycles 3 года назад

Need to take it off. Change the bearing and both seals or you might be going back in there sooner than you want! Like and share the vids!! Thanks for watching!!

@dannypateman7336 7 лет назад

sorry to ask something that pretty much seems so straight forward... you have to drain the gearbox oil first before removing the case am i right ?

@goboardcanada6263 7 лет назад

It'll drain when you pull the cover...

@wesleycunha9138 5 лет назад

is the same axis as the yamaha yfz 450cc ?

@brianvilca5607 9 лет назад

@CoteMotorcycles 4 года назад

Thanks buddy!

@j00st1010 9 лет назад

i was told to not put a light film of oil on to the new gasket for the crank case to put it on dry. is there a difference ?

@CoteMotorcycles 9 лет назад

The gasket is an oil barrier so it's best to put it on dry. If anything, use a thin film of liquid gasket on an oil free case surface and new gasket. Brake clean works well to remove oil and tip the bike a bit away from you to keep oil runoff from seeping out while you replace the cover. Hope that helps. Thanks for watching!

@joski9030 7 лет назад

Very helpful Absolutely no need to remove clutch cover though 👍🏻

@CoteMotorcycles 7 лет назад

Jo Ski we filmed a few different videos during one disassembly. Thanks for watching and glad you found it useful!

@joski9030 7 лет назад

CoteMotorcycles Now I understand as the top ends off towards the end of the vid. It was more than helpful I recommend the tips to anyone with this problem.

@joeyR1CBR1000RR 10 лет назад

Great video, but is there a tightening sequence for the case cover?

@CoteMotorcycles 10 лет назад

Not particularly. As long as the case sits on the dowels flush, no o rings are pinched and the gasket is set in between the cases you're good to tighten any way you choose. Generally I remove the bolts in a clockwise pattern, keeping track of where you started so bolts go back where they belong, then hand tighten loosely before final torque. The case shouldn't take any force to sit flush so an X pattern won't make a difference here. Main crank cases is a different story. Good question though and thanks for the comment!

@joeyR1CBR1000RR 10 лет назад

CoteMotorcycles Ok, cheers

@TheChattanoogaBandit 9 лет назад

Is there a washer that goes on the back of the case? When I pulled my case cover off a washer fell out, it looks similar to the washers that go on the radiator shroud bolts.

@CoteMotorcycles 9 лет назад

You can go check the parts fiche at bikebandit.com for your exact bike if you're unsure. Only thing that may fall out when pulling that cover off would be the water pump joint and o rings.

@oBlair65o 9 лет назад

I have an 01 yz125 and I have my seals ready to put in but when im taking the side cover off is there anyhting I have to do with the powervalve? I can't seem to find it in the manual

@CoteMotorcycles 9 лет назад

The exhaust valve is just run off a centrifugal actuator. As long as you attach the arm in its proper position and install the follower in the actuator properly you'll be ok.

@mikedews7216 3 года назад

Coolent seal!!!!

@qualitystrength6274 2 года назад

New o ring on the water pump joint where can I find that didn’t find on website

@CoteMotorcycles 2 года назад

Could be with the case diagram or with the case gasket. Complete o ring kits should have them and it’s always good to have some spare o rings. Could call a dealer and have them look it up then just get the part number and look on bike bandit or something.

@hadenflemming9011 3 года назад

Would a crf450r clutch case work on a crf450x Bc Ik the water port is different but could I make it work

@CoteMotorcycles 3 года назад

Get the proper case for your model and year of bike. The clearances from year to year will change and it’s not worth the hassle of moving things around because you’ll have to tig weld everything. Try eBay or a local wrecker for parts that will fit your bike. Thanks for watching!

@shawnp8429 9 лет назад

My crf450r overheats alot.i put a Pro Circuit y hose on it, do you think Pro Circuit pump is worth the money?

@CoteMotorcycles 9 лет назад

Don't expect much from a after market pump unless yours is missing impeller fins. Make sure your rads are clear of mud and not damaged. You should be able to see through the rad veins. You could try larger after market rads. That would be more worth while than a water pump. Also make sure your bike isn't just running too hot. Lean jetting, low octane fuel, un oiled air filter, intake or exhaust leak and many other things can cause a bike to run hotter than it should. Hope that helps and be sure to post back to let us know what you find.

@Agholston865 8 лет назад

mine is leaking oil from that hole would it still be the same seals to fix it ?

@goboardcanada6263 8 лет назад

Same seals.

@salisburyplain998 9 лет назад

great vid ,I have been watching as many water pump vids as possible ,I have replaced 3 water pump seals on my 2013 freeride 350 and trying to see if I,m doing anything wrong ,you mentioned putting grease on the seal ,what sort of grease ? as I have been fitting them dry and there failing every 10 hrs.

@CoteMotorcycles 9 лет назад

You had better check with KTM on what grease will be compatible with the seal. I'm not familiar with that particular set up so I'm afraid I can't give you much advice. As far as failing prematurely goes - make sure there are no burrs/notches/abnormal wear on sealing surfaces, check the related bearings for failure (causing excess motion on impeller shaft) and make sure the coolant you're running is compatible with your bikes seals ect. Hope that helps. Thanks for watching and be sure to share if you like the videos!!

@salisburyplain998 9 лет назад

Thanks for the tips and regarding the grease,this I have been told is perfect for all water pump seals , MOLYKOTE 44M, 30ml Silicone Grease, -40 - 200˙C plastic, gears, rubber seals.

@henrybonini9507 8 лет назад

Do you have to replace all of the gaskets?

@goboardcanada6263 8 лет назад

You can reuse gaskets but I recommend using gasket maker / sealant along with the old gasket.

@awittypilot8961 10 лет назад

Why would you need to remove the clutch cover? It's not in the way when you take it apart or put it back together

@CoteMotorcycles 10 лет назад

We filmed the clutch removal portion before doing this video. It doesn't need to be removed. Thanks for the comment!

@Cov930 8 лет назад

+CoteMotorcycles is there a way to get in contact with you ? I have a few questions

@CoteMotorcycles 8 лет назад

+SnorkeldNlawd , you can get a hold of me on Facebook or messenger and I'll see if I can help you out.

@Cov930 8 лет назад

+CoteMotorcycles i messaged you on there thanks man

@brianhallingrd2357 6 лет назад

10 NM at all the screw??

@TheChattanoogaBandit 9 лет назад

Is it possible that you can just replace the outer seal and stop the leaking?

@CoteMotorcycles 9 лет назад

Since you're in there already it doesn't make sense to only replace the outer seal. The cost of the parts is minimal so I always replace all related components. Up to you if you want to chance it, be sure to clean up the impeller shaft with emery cloth if you're not going to replace it. Good luck and thanks for watching.

@TheChattanoogaBandit 9 лет назад

Thank you

@FranciscoHernandez-ws9ip 4 года назад

Are these the same for the trx 450r atv

@CoteMotorcycles 4 года назад

It’s been a while since I’ve worked on one but I think so! You can compare parts on bikebandit.com; they’ll show you a parts fiche you can compare for both units. Hope that helps! Hit us with a thumbs up, it helps!

@yeahwerepthesamesmartech7113 8 лет назад

this clutch cover case has latched on stronger then last gf lol is there any good way other then brute force to get this off

@yeahwerepthesamesmartech7113 8 лет назад

nvm I got it a few pry bars on the little ledges above the water pump and below the clutch

@CoteMotorcycles 8 лет назад

Check for missed bolts and when you're 100% sure you got them all you can give the case a tap with a rubber mallet or use the pry points to free it. Don't pet on the sealing surfaces or you'll have leaks.

@CoteMotorcycles 8 лет назад

+CoteMotorcycles *pry

@aaronjefferson4479 3 года назад

So did you drain the oil out first?

@CoteMotorcycles 3 года назад

You don’t have to but it makes way less of a mess if you drain the oil and coolant before pulling engine covers. There are videos on the channel for everything you’ll need. Make sure the bike is cold when you are working with the cooling system. Thanks for watching!

@thecanadiancrew804 9 лет назад

so would this be the same way to if mines 02?

@CoteMotorcycles 9 лет назад

Should be pretty close. Good idea to get an online manual for your bike to use with the video. Should be able to find one for free on a forum ect. Good luck and be sure to share the video if you like it!! Thanks for watching!

@thecanadiancrew804 9 лет назад

CoteMotorcycles yea its all the same just i have to go in deeper and change the berings on the other shaft that spins that little one...fun

@Agholston865 8 лет назад

it's a 05 trx450r

@jeffward6166 Год назад

No need to take the clutch cover off
