Test fitted my Graupner 10" on 2216 Tiger Motor, which came with a Graupner adapter to fit properly.

I have pushed the prop onto the shaft with adapter which was tight, and figured I need to trim down about 1-2mm of the adapter because it is taller than the prop.

I now cannot remove the prop from the shaft! It was very hard to to get on, and seems impossible to remove. I have soaked in wd-40, with no avail.

Advise please!

Spin your prop and it will come out!

Is this a genuine Graupner adapter ?
They're made in aluminium, they're white.
Their lenght is correct, there is no need to trim them.
Did you use Loctite ?

block of wood with hole to suit adapter . press it out in a vice .

It rather seems to be a Czech substitute for Graupner adapter with apparently approximative dimensions.

These bore size reducers are designed for Graupner CAM propellers, allowing them to be fitted to various shaft sizes whilst maintaining accurate centering. They are also suitable for Graupner Elektro propellers and many other propellers with 8mm bore.
Made in Czech Republic.
