Default Water Pump 2003 CR 250

     

I just bought an 03 CR 250 the guy put a new cylinder and head. Looks like he took the right side cover off completely because all the gaskets are new. The pump is sipping out through the weep hole on the the case cover. I took the pump cover off and the impeller moves when you turn the bike over.

Does any one know if it could be the seal or the water pump is out. Its dripping just like a car water pump when they go bad.

If it is leaking from the weep hole, them its time to rebuild the coolent pump.
If its like my old 96 cr, then you will have to remove the casing that the coolent pump is in which is also around the clutch, so be sure to drain your oil before removing it.
I used a 3/8" impact to remove the nut from the shaft. Then replace both seals and the bearing & reassemble.

IIRC the seals, bearing and gaskits costed around $40.

This, with the exception of the impact. The water pump shaft should have a flat spot on the opposite end of the impeller that you can grip with a wrench.

Mine was so tight that even with vice grips on the other end I couldnt get it to come apart. Impact was the only want to get mine off, I guess the last person that was in there probably tightened it down a bit to much.

Usually if it is leaking out of the weep hole that just means that the seal behind the water pump is bad. My YZ has a similar set up, all I had to do was take the impeller off, replace that seal and the problem was fixed.
