top left screw hole for the gearbox, go to ace and get a grade 8 bolt 1/4-20 thread. Longest one I've found there is 1.5 long which is just barely long enough but will work. Use ONLY that gearbox hole for the bolt it will snug up to the rotor to lock it very tight so you can get the blade off. Use any of the other 2 holes the bolt will go through the windings

Thanks Carl, but this is very different with little screws and no holes in the rotor. The rotor has some shoulders but hard to hold onto due to the skeleton construction of the back. I’m just seeing if anyone knew an easy way. Figured you would know the trick.

I have done it a different way but you will have to wait until I get home.

You put the screwdriver in the motor like in the photo and make sure it doesn't hit the windings. Make sure it rests on the rotor in the picture. You put the screwdriver in the other vent hole to take the blade off. Also do you know how it comes off. The rotor has those tabs on the rotor, make sure they are facing vertical when you put the screwdriver in. It also works on the 77648-SO model.

That silver thing is the screwdriver. There is a lip on the rotor that you rest the screwdriver on so it doesn't hit the windings.

If you don't know how the blade comes off you turn the blade how it would run if is was on and you turn the blade the opposite way to put it back on. Make sure the little shaft in the middle is in the little slot on the blade hub when you put it back on.

Thanks for the help. I knew there had to be a trick. It came off with no problem.
