I'm rebuilding the water pump on my '87 lt250r quadracer. It's been awhile sine I took it apart, and I don't remember how to put the seal behind the impeller head. Which side goes against the impeller head, the rubber side or the ceramic side? I think the rubber side goes against the impeller and the ceramic side goes against the mechanical seal, but I want to make sure before I put it back together. Are there any other tip's I should know when putting this thing back together? Thank's for any help you can give me.

 

WHICH SIDE IS THE CERAMIC SIDE. I AM LOOKING AT A DIAGRAM. THE THICKER SIDE AGAINST THE SEAL AND THE THINNER SIDE AGAINST THE IMPELLER.

 

I asked the local dealer today and he told me I was right, the ceramic side against the mechanical seal. Thank's for the help.

 

Be sure to use bars leak or it will leak from the weap hole.

 

It shouldn't leak if he replaces the seals. I had to replace mine because it leaked, but once I had the new seals in it didn't leak anymore.

 

I put it all back together and it didn't leak, but I am going to put some bar's leak in it anyway just to be sure.

 

Suzuki actually recomends bars leak
