Subject: [LML] Engine = Crankshaft=20 Expansion Plug

Guys -

I'm planning on running my Lycoming = IO-360-B1F=20 engine for the first time this summer, then sometime later removing = the=20 propeller and trailering the aircraft for painting.  With my = trailer=20 setup, it is better if the prop is not installed because the air = causes the=20 prop to rotate.  Plus, rocks could ding it up on the=20 road.

According to a Lycoming Service Instruction (number 1435, = dated=20 1986) there is an expansion plug at the front of the crankshaft which = must be=20 removed in order to get oil into the constant speed prop.  = Apparently the=20 plug stays in place if using a fixed pitch prop.  I have an MT = 3-bladed=20 oil controlled constant speed prop.  My engine already has the = prop=20 governor oil line installed.  In fact, the governor is mounted as = well.

Two questions:

1)  Must the expansion plug be = removed=20 if the engine is only going to be idled at 1000 RPM for one minute and = no=20 attempt will be made to cycle the prop?  (In other words, will = the prop=20 be damaged if it is not supplied with oil?)  If so, how do I = remove it --=20 short of poking it with a screwdriver and prying it = out?

2)  If I=20 do need to remove the plug to run the engine, can I just put it back = in when I=20 remove the prop?  Do I need a new one in order for it to seal=20 properly?  (Obviously, if I poke it out with a screwdriver I'll = need a=20 new plug anyway...)

Thanks in advance.

- Rob=20 Wolf

p.s.  I thought I was very close to running the = engine=20 until I made a list of everything I need to do first.  It's three = pages,=20 single spaced.  Sigh.  It never ends....
