    Parts ski tear down

    Got the engine core out of the parts ski tonight...heavier than I expected!

    Looks like I will have to fab up some tool to get the flywheel loose.

    So far the only losses have been the crank upper half and MAG cylinder.

    Use the rope trick in a cylinder to hold the crankshaft while you torque the flywheel nut off.

    I got the nut off easily enough by dropping an appropriately sized ratchet into the crank/arm inlet. Already had the cylinders off so no rope trick.

    But I need to find a way to pry off the flywheel, it ignored my whacking it with a deadblow. I think I will just make some small arms for my existing gear puller to go into the holes on the flywheel. Normally I would just drill a piece of stock out and span the shaft, but that means three holes and a plate here. Ah well if I have a plate the right size that would be easy on the rotary table.

    Hmmmm...

    You can usually get them for free on their tool rental program. Although I found myself renting it so much I just paid the darn thing.....
