Hi guys could anyone please advise on how to remove the front prop bushing please?
it has a small collet on the inside between the crank and the bushing, I'm presuming it is a tapered fitting but how would I remove it please ?many thanks Simon.

If you have a heat gun, try heating the bushing and than gently pry it with a screw driver. Most collets are made either from brass or aluminum and will therefore expand more than the steel crankshaft.

I save up broken APC props. They have sharp edges. I wedge them behind the prop driver from each side and mount the two prop blades in a vice. Carefully squeeze the vice so that the old prop blades wedge even further into the gap, and gently heat the driver. It should pop off. I usually leave the prop nut (or spinner) on so that the tapered collet doesn't fly off. Prying with a screwdriver could mark the driver and/or the crankcase.
