Afternoon LJer’s,

While I was on my recent deployment I ordred all of the stuff for the ultimate HF DC Mod. The rikon impeller, Wynn filter, Super Dust Deputy, extra hose, plugs, remotes, and all the fixings. Today I finally went to put it all together and couldn’t get the impeller off the shaft of the motor…no matter what I tried.

So, here are the questtions.

Am I missing something for the removal of this thing. Every video i’ve watched, and post/blog I’ve read about this mod…and I think I’ve read them all…states that you just pull the one hex nut off and use a puller tool of some sort to pull it off. Nobody seems to have problems getting it off. I tried so hard that I ended up breaking the lip off the impeller center post. I even went so far as to drill three equally spaced holes through the stock impeller, right next to the center shaft, and tried pulling from there. I ended up doing nothing but bending the shaft on my pullers….both pairs I tried.

If I buy another HF DC to use a new motor for the mod…since i’m already invested into the build….am I going to run into the same problems or has the last three years of outside storage been tough to the DC that I had and that is the problem.

If you were in my shoes and all you really need is the blower/motor peice would you just purchae another HFDC or would you buy something else. I saw that Penn State Industries sells a 3HP model for almost $400. If I were to buy that then I think I should sell all the parts and pile up the $$$ and just buy a Mini-Gorilla or something of the sort that already comes with a two stage.

Thanks for the feedback everyone.
Roger

Interesting. So, all you need to do is get the old blower impeller off. Cut the old impeller off with angle grinder with a cut off wheel, followed by a cold chisel and hammer when you get up really close to the motor shaft? Also, soak that impeller/motor shaft with PB blaster or the like if you go back to trying to pull it. I think you’re right. It’s just a remove the nut and pull it off operation. I think you need to not let it beat you.
