    Default Cincinnati 2u Universal Grinder help.

    [ATTACH=CONFIG]217989
    Does anyone have a parts diagram of the coolant pump for this machine? I need to remove it and not sure if I have to unbolt it from the bottom mount at the pump or just remove the motor on top. Will I loose fluid or is that a dry connection at the pump? Thanks,Darrel

    Doubt you can pull just the motor unless there is a hole in the housing under the motor to disconnect the impeller shaft . You have to pull it by removing the bolts around the lower flange. That's not a dry connection if I remember correctly- you better plan on draining your coolant before removing the pump or you might well have a big surprise on your hands.

    Thanks Dan. I had that off a long time ago but can't remember what it took. I guess I'll get the barrel and pump ready.

    Update- There is no shaft seal on this one. Just length of the shaft keeps the solution separated from the motor. There is a nut on the bottom of the impeller and the shaft housing slides off from the impeller end. I indeed had to drain some of the grinding fluid to take the pump housing.

    Thanks John. Good to know. I dropped the pump motor off today at the motor shop and they think it will be quit pricey to rewind. I wanted to sell the grinder but this may change things. Thanks again, Darrel

    Yea, it kinda looked like the motor was above the coolant level- that way no shaft seal is needed. Nothin is ever simple!
