Once again, I find myself posting about water pump probs... I ordered all new parts for the water pump on my 99 YZ400. When I installed everything per the Clymer manual, I notice the shaft doesn't spin the bearing. The bearing is seated properly in the housing, but when I turn the impeller shaft, it spins inside the bearing, but the bearing doesn't move at all...almost like it's binding. I can get it to spin a little, but I have to force it. Will it free itself when it gets warm from the motor or what?
