Oil/water sealing change....just to be sure

[PiotrK100]

I know I'm boring like a hell but what to do when doing something for first time (this bike)
Well, I just changed both sealants in oil side and water sid according to the manual so did it corectly http://www.ibmwr.org/ktech/water-oil-pump-rebuild2.shtml  . All went perfect. I screw the impellor and when splin with the hand it not goes smoothly as I expected but it is a little noice like metal to metal wear. Is that normal? Also question, the spring from the water sealant is splin together with the washer and impellor? Is that correct? Looks it is to me but strange.
I pull back again the shaft to see for any possible damages in the sealants but nothing like that was visible, so mount that back and screw with 30Nm.

Sounds to me that the ceramic face is broken. Place the pump on the bench with the impeller pointing up,
seal of the in and out ports With some tape.....fill the area behind the impeller with water, turn the shaft,
check for leaks.

[PiotrK100]

But how come the ceramic can be broken as no force was added? I can  not check it with water because here is 11PM  but will do tomorrow. But also I do not know if that is the reason because water system is under pressure. Anyway, in case you are right what can went wrong?
It is not cheap part so I did a mistake or what? But again, all was as stated.

A lot of owners have been wondering about what went wrong when mounting this seal, some also second time.

Did you order the spacer together with the seal....it have been a lot of different seals over the years, and it
also have been two different spacers....if I remember correct.

[PiotrK100]

I did buy a set according to the realoem and the new spacer too. It is a diffrence betwen the two spacers, so I mount the right one.
All looks ok but when I do spin it need a force not much but more than expectation and that noice like loud friction. Maybe it should be like that and all will set up when start up the engine. But must be sure.

[PiotrK100]

I fill up impeller and the area with water turn the shaft left and right and........no leaks no drops.

[Inge K.]

If the oilpump gir/shaft/body was mounted completly dry and not lightly oiled, it could maybe be the reason
to the problem?
Beside this I have no further ideas what causing your mechanical noise.

It's hard to tell from the 2nd pic, but it almost looks like the impeller is touching the pump housing. I don't know the specs, but I would imagine that there should be a few thousands clearance across the entire edge of the impeller blade.

I agree with Scott.  I think there should be some clearance with the impeller.  Is it possible to remove the impeller and test again for your noise.  The meshed gears do offer a little resistance; they are not meant to spin as if on ball bearings but there should not be large resistance to spinning either.  The first picture looks OK to me based on what I can see.

[PiotrK100]

The pic with impeller is not from right angle. Impekker do not touch the housing at all, spis freely and even more it hase like 0,5mm clearance and when I push impeller it moves a bit and spring react back.
But regarding the spining part of the sealant; we pull the shaft thru sealant with the bolt (which takes a force) so that part must spin together as there is no clearance between shart and that part. So impeller, spacer and internal part containing spring slon together and that is right. That is what I think.

So impeller, spacer and internal part containing spring slon together and that is right. That is what I think.

Correct, this type of mechanical shaft seal have a stationary part and a moving/turning part.
