I don't know if this is the correct place for this post but here goes. I recently pickup up a small (3hp) chipper leaf vac. The brand name is yardvark. I am trying to remove the impeller off the engine shaft. It appears to have a keyway, I have tried a puller but nothing also a lot of pb blaster. Any thought out there on this. Also would be nice to find info about this machine so far I'm not finding much. Thanks for any help

With tension on the puller, did you try tapping the end of the puller with a hammer?

Sometimes adding heat to the impeller near the shaft helps. Do this while there is tension on the puller. Don't get too carried away with the heat. Too much is not good.

Thanks for the help, I did tap it but I did not use heat, sounds like heat is the way to go.
