Is this pump all one unit, or just a shaft that connects to the bottom of the pump? If it's all one unit, i would take it off. Wouldn't there be lack of lubrication?? If just the shaft, leave it in! /ubbthreads/images/graemlins/wink.gif Then again, if I had to take the dif down to get the pump off anyways, I would just do it right and block it off, no? /ubbthreads/images/graemlins/dunno.gif
