    I recently acquired a 2000 exmark lazer z with a 23hp kolher engine and it has about 3100 hrs on it. It had a small oil leak coming from the crank seal on the pto side but it has began to get worse. Im mechnically inclined just wondering how hard this is to change this before I dig in. Also I know this machine has high hours but it runs and cuts great but the hydro whine loud when it is in motion or under hard load like up steep hills is this normal or should I be worried? All comments are appreciated thanks in advance

    If I'm not mistaken you'll have to at the very least take
    that cover off, so you'll probably have to pull the engine and
    you're looking at internal engine work, whether it involves setting
    it back to TDC or what have you, that I couldn't say.

    Lazer Z uses side shaft motors... Pull the bumper , remove the clutch, replace the seal.
    Be sure not to scratch the crankshaft.

    Hydro's on Lazers whine...replace the hydro filter regularly...replace the dampners and it will drive like a new one.

    Is it the Model CV23 ?

    Why not download the service manual? Kohler lets you download
    their service manuals for free; they're not communists like Stihl is.
    From what I can see, the oil pan doubles as a PTO side cover.
    Doesn't look too hard to me. :shrugs:
