tanaka prop remove

[marioscib809]

now spark is ok only the points need to be cleaned,any idea how to remove the prop because it seems to be a one whole piece with shaft it is an aluminium prop, if i leave it this way and accidentally hit something the shearpin won t work and gearbox will be damaged,am i right? is it risky to use a small 2legged puller?considering the shape of the prop with very difficult puller seating.
