I'm stuck and need guidance on how to properly remove the water pump impeller on my 1998 yz400f. I have all new seals and will check the shaft once removed but I'm not familiar with the impeller removal. When trying to remove the impeller the motor turns over so that tells me I'm missing a step. If anyone is familiar with the '98 yz400f I could really use the help.:thumbsup:

You need to remove the right crankcase cover from the engine so as to hold the inside end of the shaft with a wrench. There are flats there (NOT the drive tab) for the purpose.
