I'm planning on running my Lycoming IO-360-B1F engine for the first time this summer, then sometime later removing the propeller and trailering the aircraft for painting.  With my trailer setup, it is better if the prop is not installed because the air causes the prop to rotate.  Plus, rocks could ding it up on the road.

According to a Lycoming Service Instruction (number 1435, dated 1986) there is an expansion plug at the front of the crankshaft which must be removed in order to get oil into the constant speed prop.  Apparently the plug stays in place if using a fixed pitch prop.  I have an MT 3-bladed oil controlled constant speed prop.  My engine already has the prop governor oil line installed.  In fact, the governor is mounted as well.

Two questions:

1)  Must the expansion plug be removed if the engine is only going to be idled at 1000 RPM for one minute and no attempt will be made to cycle the prop?  (In other words, will the prop be damaged if it is not supplied with oil?)  If so, how do I remove it -- short of poking it with a screwdriver and prying it out?

2)  If I do need to remove the plug to run the engine, can I just put it back in when I remove the prop?  Do I need a new one in order for it to seal properly?  (Obviously, if I poke it out with a screwdriver I'll need a new plug anyway...)

Thanks in advance.
