Quick UK fan for os 50
Im still flying my TT50 from time to time. It started making some weird noise and I decided it was the rear bearing in the engine. To replace the bearing I had to remove the Quick UK fan. To do this I had to heat the fan hub with a torch and tap the crank through the fan and out the back of the engine. Now I'm having trouble getting the fan back on. Do I need to get the brass collet out? I don't think its going to come out. All I can think is to heat it and try to force it back on.

The brass collet was really stuck in the hub. Going down through the hub I got a small screw driver on the collet but couldn't tap it out so I heated the hub and then cooled the collet with a cotton swab with water on it. The rapid cooling of the brass helped free it from the aluminum hub and I could tap it out.

The conic brass was "inserted" on fan hub when you tighten nut.

Why you need to pop up this brass? I understand you need to replace it... Isn't it?
