I've always used rope to hold the piston when removing clutches, but I was wondering if the collective wisdom here has a preference... a length of clothesline or a metal piston stop, or ???
The "safest" way to lock up any engine for clutch or flywheel removal and installation is to hydraulically lock the engine with some light oil. Rotate the engine in the direction that you need it locked in until the piston is almost TDC and the fill the cylinder with oil through the spark plug hole. Re-install the plug and you can SAFELY put whatever torque is necessary to remove or install either side without worries. I am not saying this is the cleanest method but I promise you will never damage a piston like this because the load is evenly distributed over the entire surface of the piston deck. I have done this for years on everything from RC car engines to snowmobile engines and it works like a charm every time without the "pucker feeling".
That sounds interesting. I would think you would need to be extremely careful not to allow the piston to drop back down and lose oil into the ports. Also I assume you are using a heavy oil so getting it back out needs flushing.

Recently, this thread came up... see for pictures of what a metal piston stop did to a piston. I'm going rope from now on.
