... and the lip of the hub broke off. I rotated the gear puller slightly to regrab what was left of the lip and it broke off more parts. Looks like the hub is stuck and now I don’t have any lip to line up w/ the gear puller arms (3 arm puller).

Any other ideas to pulling this thing off. I am at point of no return so need to get it off and put the new bigger one in.

Thanks for any advice and ideas.

You can see the lip broken in a few places. I am thinking at this point need to just crack the hub and dump this impeller, esp since I have a new one. Don’t know how else to grab on and have leverage to get it off.

With some tension on the puller did you hit the bolt end with a hammer before trying to just cranking on the bolt to remove?

I didn’t and know now I should have been now trying it with the bigger gear puller pulling on the outer disk and doing it – it’s not budging. I don’t know if it’s rusted in or something.

I am about to put a grinder to it to cut it out… frustrating.

You do know they just unscrew right?

lol, j/k

I had an old DC that I tried to get the impeller off. Tried everything from heat to a bigger hammer. Never got it off. Chucked the whole damn thing. Was going to anyway.

Crazy thought, whack it with a hammer to jar it kind of loose, then maybe use multiple snap rings of that size to create an edge for the gear puller to work. Just thinking of possibilities of what I would try if I had that problem.

Thanks all – I tried a bunch of things… that were destructive probably half from frustration and playing on tilt. But eventually I got it off by drilling a bunch of holes to create larger holes to fit the gear puller hooks into. Then it still took a humongous amount of torque-ing until finally getting it off.

Either split it by cutting most of the way through with a sawzall and cold chiseling it. Or drilling and tapping holes in the hub and putting a different puller on.

Personally, I’d split it and be done.

Then there is always the “grind a slot or two in it” trick. I’ve had a few things over the year that I had to grind deep grooves in to get them off. Bearings, immediately, come to mind.

You could use an angle grinder to get most of it down, then switch to the exploding Dremel type wheels.

If you can work over the keyway, if there is one, you get a bit more leeway. If you can get it down to, say, 1/16th, a sharp cold chisel toward the motor and bearing (so you don’t risk bending a shaft, might spread it enough to pull off.

Just for information. When you put the new impeller on and you screwed up the threads on
the the shaft with the puller you are going to need a 6mm left hand tap.Don’t ask how I know this.
