[@83226505]

Love your range of K100 videos. They are simply the best! This one about the oil/coolant pump is superb. Where did you get your drift for the seal from and what size is it? Cheers.

[@damundaka13]

Man I love your channel I own a k100 btw lol

[@cyclepreacher3799]

Nicely done as always mate. Will we see a vlog on the K100!?

[@kennyraceboy]

Thanks! There will definitely be one as soon as my k100 is back in one piece, hahaha!

[@danhix1371]

awesome video. helped me a lot. Is the impeller suppose to spin freely? mine seems to be a bit tight. CHeers!

[@ar_pe4012]

You really helped me a lot with your instructions, thank you! :) just one little point I noticed. I don’t know if that was on purpose but you put the gasket maker on the outside of a screw hole. That sometimes causes oil leaking through the thread of the screws. Otherwise great video! 👍 Edit: I just have one more question. As soon as I tighten the bolt the wheels won’t spin freely anymore. Could it be that the spacer is to big so that it squeezes the sealing of the water pump side too much?

[@sidcity5155]

Did you ever find out what can cause the wheel not to spin freely? I am having the same issue.

[@lo2lotte]

Great video! At what website did you buy all your parts? I have exactly the same problem.

[@betsyrossband]

Ever flush the abs system? Thanks for the help.

[@alfestfer]

Hello, the small black oil seal has a conical part, that part goes to the side of the pinions, or to the side where the other seal goes?

[@marloesakkerman746]

Hello, I'm asking a question for my father. He is reassembling his K75 water and oil pump and he wonders where to place the large black O-ring (second from the left on 4:15)? Thanks in advance.

[@markpupetx]

So if there is loosing liquid, ¿allways is a mixture of coolant and oil? ¿What happens if only is coolant?

[@mruniverse5704]

02:30 is it ok if filled mixed with dirt and grease?

[@ricjenkins8005]

It's been suggested that you can check the condition of a water pump simply by taking the cover off and "having a look". I don't believe this. What do you think?

[@nigelbiscombe9199]

And then watch it leak as he shattered the ceramic seal from hammering it

[@simonassinica8412]

Do some one know, were to buy this seal tool?

[@danhix1371]

thanks for the awesome video. I'm struggling to get the number 8 seal in. it seems like there it too much room and the seal keeps sliding out after i try to whack it in.. any suggestions?

[@palmreader311]

same problem did you ever figure it out?

[@Hamkaastosti1]

Is it possible to give the dimensions of the seal installer tool so I can 3D print one? Can’t find the tool anywhere near me.

[@juliensegard9621]

Bonjour je dois changer mon joint de pompe à eau pompe à huile ou as-tu trouver adaptateur pour rentrer le joint ( la pièce noire) merci

[@stevieg7403]

Could you explain a little bit more about seating of the oil seal. Looking in my pump housing it’s not exactly obvious of what you’re seating it to I’m bit confused

[@beemrdon52]

Bmw parts fiche might help.

[@ropulix]

Hello Ken, I am having hard times in fixing my K75 ‘92 water pump. After replacing seals o-rings and the shaft some drops of coolant, apparently clear and without oil, come out of the draining hole. What does it mean? Thanks for the reply

[@beemrdon52]

It probably means that you will have to do it over.

[@palmreader311]

shaft seal is not seating

[@terminator-ct8862]

Come si chiama l’attrezzo per inserire il premistoppa ?
