    this is on a kohler command CV18s.

    the oil seal (where the power take off comes through the oil pan) is leaking.

    how do I go about changing the seal? do I have to take the oil pan off? or can I do it with it on there? do I need an special tools to do this? thanks.

    I replace these seals all the time,I use a automotive seal popper which is probably something you don't have. A standard screw driver will do,With the engine on its side take the screw driver and insert it at a angel with the handle a couple inches from the pan between the inner part of the seal and the crank,LIGHTLY tap the driver with a small hammer untill its under the metal lip of the seal and push the handle down against the pan. Do this in several places around the seal and one of the times will pop it out of the pan.
    To install the new seal I use a piece of PVC pipe the same size as the seal with a cap on one end.
    (Be careful not to gouge the crankshaft)
    I use this method on all engines.

    so the screw driver goes between the inner part of the seal and the pto?

    (blade)
    You are calling the pto the crankshaft are you not ? one side of the driver will be facing the seal and the other side will be facing the crankshaft !

    well isn't the crankshaft and the pto (power take off) the same thing? what I am trying to get at, is that the screw driver goes on the INSIDE of the seal, and not on the perimeter, right?
