Ryobi RY09466A 4-cycle blower. The pull string broke and is located behind the turbine so obviously the turbine must be removed in order to replace string.

I have never seen such a nut/washer apparatus and it seems impossible to remove as it has five barbs holding it into the turbine. The video on youtube shows this same blower being disassembled but with a normal separate nut and washer as does the exploded parts diagram on ereplacementparts.com.

Does anyone here have any clue as to how to remove this ridiculous conglomeration? It is making a relatively simple task of replacing the string impossible. I could attack it with my air chisel and replace it with a normal nut and washer but one tiny slip and the threads are ruined on the shaft plus the turbine is plastic so it probably would not survive.

Thanks.

To me it appears to be a simple nut with a special washer.Is the washer formed to the nut?

Yes- I thought I had explained that it was all one unit. That is the problem.

You will most likley find the nut and the impeller come off as a unit.
All the Stihl backpack blowers come apart like that.
I am trying to make one up from 4 dead ones at the moment.
The dealers usually cut them off then fit a new one.

Ryobi design all their products to be urepairable. It is part of their corperate philosiphy.
Build a product that is very comfortable to use and does it's job really well bt can not be fixed so you customers will just buy a new one.
Just imagine how much a shop would charge to replace that chord.
More than the purchase price of a new blower.

The vaned blower was threaded LH if I recall , on my much missed 790R whacker. Yes, the stuff is throw away unless you can amass a pool of free used parts.

Mine is right-hand thread. So I suppose I will need to find a way to keep the crank and piston from moving and it will all come off.

Remove the spark plug and turn engine to bottom dead center.
Stuff as much plastic rope as you can down the plughole, turn the engine to compress it. turn it back the other way and stuff some more in there .
Continue till you can not get any more in then compress the rope .
This will lock the crank and do no damage to the engine so long as it is as close to BDC as you can get it.

The more I look at your funny washer the more it looks like a T nut.
The thing they hammer into the bottom of wooden legs to screw caster wheels and leveling feet into

That is exactly what I thought it was. Made for wood working.
