RE: 46FX rear bearing won't come out
G'day Mate,
Heat it to 300F in the oven for about 15mins, & try again, it must be hot while you are hitting a wooden block with the back of the engine, you must hit the block with the engine crankcase flat on it, it will be gum or varnish that is holding the bearing in place, was it run with Castor oil in the fuel.
Good Flyin Mate,
Allan.
