    Im trying to take the shaft of the impeller of my leaf vac to modify it. I take the bolt off and i get half the motor of and it gets stuck, i just cant get it off, is there something holding it on? Its a Briggs motor on a giant vac....any ideas? ive tried prying, but it doesnt work much

    Well, The key is in the crankshaft. Some fans have threads in the hole once the mount screw is removed for a larger jack bolt can be installed to push it off. If yours doesn't I don't really have any answers because I'm not familiar with this unit. The only thing I can say is spray the piss out of it with penetrating oil and keep working it back and forth until it comes off.

    What is it you want to modify on this thing ? You do know these fans have to be balanced don't you ?

    why do you say that? got any tricks, the fan itself cant come out because its bigger than the opening, but i wasnt planning on doing that, i just want to take the motor off. Any help? lol it would be appreciated

    Unless this is a fairly new unit, it's almost impossible to remove the impeller (no way to impart motion to separate the impeller from the shaft), which by now has rusted itself very well to the motor shaft. By the time you bang it out, the motor shaft usually becomes bent.
    Hope this save you some time,
    It's too bad they don't weld some tabs on the impeller to facilitate the use of a heavy duty gear puller.
