Default Replacing impeller in Craftsman Electric Leaf Blower/Vac

I need to replace the impeller in my Craftsman Electric Leaf
Blower/Vac. I've disassembled the unit, but am not sure how to remove
the existing impeller from the electric motor. The new impeller
appears to be threaded inside. Any suggestions?

Thanks,

Phil Pickett

you need to get a hold of the armature in a way that wont damage it so you
can unthread the impeller. some units have a slot at the top end of the
armature for a screwdriver or the top end of the armature will stick out
enough that you can use a soft jaw vise to hold it while you turn the
impeller off.

When something is screwed onto a motor shaft, it should have some
nondestructive way to keep the motor from turning while the item is
unscrewed (assuming that the system is well designed). Look for a hole
somewhere into which you can insert a pin (allen wrench or something
like that) to lock the rotor. If you can see a fan in the motor, you
might be able to place a screwdriver blade between the fan blades to
hold it, but only if the fan blades are substantial, and not thin sheet
metal. You don't want to bend them or you could be looking at a motor
rebuild job.

dont know what model you have, but did a replace of a plastic part on a
metal motor shaft that did nto see to want to come off.. i had to hold
the shaft with vice grips(from the other side of the motor and then turn
the impeller the other way to get it off.. just make sure you dont have
a metal stud(pin) on the other side of the plasticc impeller holding it
on(somthing like a pin through the metal motor shaft right up against
the plastic impeller????
hope this helps.

you are right they are designed to remove items that are screwed on and on
the item in question the end of the armature will have a slot in it for a
screwdriver in it to hold it or it will stick out far enough so a soft jaw
vise can hold it.
Sticking something into a fan blade no matter how substantial is not the
proper way and will always have a risk of doing damage. these unit in
question here do not have a hole to lock the armature / rotor with a pin of
sorts. this is more common on weedtrimmers to remove the spool assembly.

Check the rotation direction. Very often the threads are LEFT-HAND, i.e. you
turn the plastic piece to the right to loosen it. A rule of thumb that seems
to apply in these cases is that the motor will turn in the direction that
would tighten the blade on the shaft, not loosen it, so you need to turn the
blade in the direction that the motor turns to loosen it.

There's also often a nut screwed onto the same shaft above the fan blade.
Whichever way removes the nut is the way you need to turn the fan blade.

Why not just call or go to the Sears service center. They should be able to
help and probably have a computer dispay showing the break-down of the unit.
Maybe the impeller is fused to the shaft and it has to be replaced at a
whole unit.

Good Luck.

Good Morning Phil,
I am replacing my impeller but I don't know how to remove the "sleeve ferrule" to separate the body. Maybe a mallet to force the sleeve off?

Thanks,
Pat
