How To Change The Water Pump On A yamaha yfz 450

[@SaudiFalcon6927]

Many thanks for your vedio, I have replaced my yfz450 - 2008 water seals and gaskit 👍🏾.. Gave you BIG LIKE

[@betsy450r]

In case the seal goes bad the hose just directs the coolant downward, this is called a weep hole

[@omarchavez1144]

If my weep hole is leaking what Seal is it?

[@angelmendoza1876]

@@omarchavez1144 it’s not a specific one, the weep hole just means the seals are bad and it’s time to replace them

[@spincr4hire72]

Great help. Thanks for posting !

@@omarchavez1144 If it's only leaking coolant, it's the outer seal. If it's leaking oil, it's the inner seal. If it's leaking coolant and oil, it's both seals.

I have a 2024 YFZ 450R with not even 13 hours on it and the water pump seal just went bad! Is that common? Why did it go bad so quickly?

[@sbz666_]

Probably one of the most common issues. I'm still trying to find out why they go bad so often. I think it might be dry rot from lack of circulation if it's been sitting too long. Your 2024 might have been sitting at the dealership for a while before you got it.

Is the impeller and shaft supposed to have in and out play?? Mine moves in and out a little.

[@BicBoiDyl]

yes

[@mario10194]

Where you get the tool to pull the impeller out?

[@Flip2theOzz]

You can remove the impeller with a 1/4" drive and socket. Put the bike in gear, use the rear brake, and give it a good firm swing. Should go off easy.

[@98bigchevy]

What was that piece you put in before you put the case back on

[@BicBoiDyl]

little cylinder that's for oil or coolant i forget

[@BlueJJ562]

Would of been a good video if there was specific directions. When I pulled out the casing 2 washers came off a copper and a black and I have no idea where they go.

[@JensEskildsen]

Look at a parts fiche for your model.

[@1mandrywallarmytv144]

did you figure out where those washers goes? I pulled my cover off of my 2007 yfz 450 and had a copper washer fall out. I did not see a black washer. Please let me know if you figured it out. thanks

[@1mandrywallarmytv144]

@@JensEskildsen there is no such washer on the diagram.It's the oddest thing. Not sure what to do other than have conversation about it and hopefully someone will know the solution

[@1mandrywallarmytv144]

when i pulled the cover off a copper washer fell down from inside of the cover. After searching the part diagram from yamaha f yfz 450 there is no such part. Obviously its not the empellar it something else . Any help would appreciated since i do not want to reinstall everything back together and not have this copper washer somewhere that is needed.

[@brentjgilmour]

It's crush washer. When you took the case off it fell off from the bottom of the oil line that went into the top of the case.

[@1mandrywallarmytv144]

@@brentjgilmour it is a crush washer for the oil was the very thing I was thinking. Thanks for replying

[@brentjgilmour]

@@1mandrywallarmytv144 @1ManDrywallArmyTV not a problem. I got a couple yfz 450's in the shop right now for a customer. I had to bring up a video because he didn't understand why im taking the case off. Lol

On the water pump witch screw has the washer

[@racequad9]

I just bought a 2006 yfz, and there's this little hose coming down from under the water pump...i haven't opened it up to see what it is suppose to do. what can it be?

[@johncumming652]

racequad9 it is the overflow, my water pump went and it was a constant drip coming out of it

[@chaos-korea]

Thanks. Very good.

[@artru17]

help bro i have a 09 yfz that i chanhe my antifreez and notice shave aluminum pcs on it what could be

[@sbz666_]

Impeller or shaft might be going bad which releases small bits of metal into the coolant system.

[@codyreid3981]

How do u know if it's bad

[@sbz666_]

Coolant will leak from the weep hole at the bottom of the case under the water pump. There's a small hose that directs towards the back of the case. Check the rear of your skid plate for fluid.

[@themotorcycleguy5980]

good vid

[@sethclarke5611]

And how to u get a stuck side cover off

[@chrisginoc]

First timer here. I have a 2006 yfz 450 special edition. I removed the engine side case today. It wast hard at all.

[@sbz666_]

Heat and a rubber dead blow.

[@Domyfz450]

Wow a lot of work for that pump is it worth it ?

[@sbz666_]

If you let the inner seal fail, you will leak coolant into your oil which is obviously a no no. So it's not just worth it, it's necessary asap once you notice coolant leaking.
