    The key is to get all the crud out of the rotor and lightly sand all the vanes removing all the sharp edges..make sure the rotor is dry and the vanes don't even think about sticking..
    Don't oil the tool until after it is assembled..
    Be careful...you can double the torque on an air ratchet with this procedure...
    I have a 3/8 bluepoint air ratchet that hits like an impact...if you didn't know about it...it would bust your knuckles and small bolts before you had a chance to throw it at me...

    A lot of good information I will go look at stuff in stump thread. I guess I was not thinking very clearly. I was think miniature jack hammer but I understand about knocking off magnets. This is what the dealer uses:

    I am not going this way, costly and with little experience could damage something. I remember someone suggested holding the engine upside down and wacking the loosened bolt in flywheel.

    Guys...... Ya don't have to remove the engine and hold up side down...... All's ya gotta do is loosen the flywheel bolt/nut, Jack the machine up and put the proper size socket on the PTO end bolt, Smack it with a BFH and the flywheel WILL pop loose every time !!!

    Been do'n it fer years......

    That is the best air hammer on the market. In don't work on small engines, but the brass probably keeps from damaging anything or magnets falling out

    Well it worked just like you said. All I needed was my top of the line BFH from Harbor Freight.:clapping:

    Ed..... I don't normally give bad info...... :nono:

    I learned this trick years ago removing a rotor from a generator engine (tapper shaft), Put a socket on the flywheel nut/bolt and smack it..... Course I'd never do it on a Kohler powered generator......
