I’ve had the motor on my zero turn apart. There’s a seal in the shaft end and a few other o rings in that motor. I don’t know how yours is constructed. If you’r motor is the same as mine was make sure you scribe a line down the case with a square before you take it apart because there’s a bunch of alignment critical plates. What’s your experience wrench turning? If your an oil changer and that’s about it than don’t do it. If you could tear down a engine and put it back together you’ll probably be fine.
