    splitting the crank case

    looking for tips on splitting the cases. I am afraid of sticking a driver between the halfs and screwing up the mating surfaces.

    Your wright dont do that if the flywheel is still on put something in there and work them apart. or take a rubber mallet and lay the motor on its side and tap the crank on the end to separate the two halves.

    Use a rubber mallet. DO NOT not use anything sharp like a screwdriver or scraper to separate the case halves as they can damage the mating surfaces and cause sealing problems.

    Tips on taking off the pistons. I know there hare clips you have to take out. Then hammer the center piece out.

    In all seriousness... Press or a little heat or you can make a press with appropriate sized sockets and clamp/vise if you're really hard-up. Don't hammer on anything when working on engines with the exception of a rubber mallet for separating hard parts as mentioned above. Components should always be worked with slow, stable methods whenever possible. One exception may be when removing a stubborn flywheel, but I avoid that method whenever possible as well.

    There's a tool for it, but it's not really necessary...
