Does the metal cup pressed into the end of the crank have to be removed 

before installation of the constant speed prop?



I assume that cup is in place for fixed pitch props.  But I can't find a 

specific reference to the need or procedure for removing it in the 

documentation.  Even reading the procedure for changing between constant 

speed and fixed configurations doesn't directly address removal of the 

metal cup.



Thanks in advance

Bill

Hi Bill:



I attached a copy of the Lycoming SI1435 that should cover it pretty

well. I went through the same questions. If it doesn't show up you can

search the nes and locate it.

Aahhh, nevermind.  I've re-read SI-1435 a third time and see that I must 

"Remove expansion plug for Constant Speed operation".  Seems pretty 

clear now.



Thanks.

I don't know the method to remove it either.  Drill a hole and pry seems 

crude.  Looks like it has some sealant on it.



Thanks.

Another comment, I have a used engine from a Piper Aztec.  The prop on the Aztec  goes to full feather on low oil pressure (Course Pitch / Low RPM).  The Hartzel prop used on our application goes to fine pitch / high RPM on low oil pressure.  With the Aztec governor, we were able to cycle the prop at low RPM on the ground during run-up, but not in flight.  Changing the governor for the MT unit from Vans solved the problem.

I believe we used  slotted screwdriver to punch a hole  and it came out easily.

If I remember right ......   Along with removing the front plug, you 

must also put in the aft plug.  In the fixed-pitch mode, oil flows past 

the nose bearing into the hollow crank and back out through a hole next 

to the #1 crank throw.  With the constant speed, you need to pressurize 

that hollow part of the crank .... hence the aft plug.  Since I've never 

played with an IO-540 before I may just be blowing smoke, but .......

Funny you mention this I just finished putting the prop on to do cowling 

/spinner fitting and went through the same questions last night.  My Van's 

IO-540 came with a sheet of warnings one of which was to remove the plug, 

but no method. I found in archives where someone used a dent puller, I'll 

probably punch a hole and then use the dent puller if its stubborn.

Also related... I had to remove a prop flange bushing to drill holes in the case for LSE crank sensor plate mount as my engine didn't have any bracket holes. It sounds pretty scary, but wasn't actually too bad.



When I went to install the prop, it was discovered that several bushings were caked with junk and needed to be rethreaded as they started coming out when the bolts were tightened. I called Lycoming and they said it was okay to re-tap if needed.



I came across Lycoming Prop Flange Bushing Location doc SI1098G (attached) which explains proper location and type of bushing required for different flanges.

Jay

I got a couple 1.5" bolts and center drilled 2 of them  I used them as a centering guide for the tap drill.  Once drilled, remove the bold and tap the hole with a bottoming tap.  I was able to get 5 holes using this method.  Have not started the engine yet but I believe I got a really good fit without having to remove any bushings.

I ended up drilling a hole, taping it, and using a screw through a piece 

of scrap to pull the plug out.  I tried prying the cap out using tools 

thru the hole.  That didn't work.



There is a rear plug installed that seals this section of the crank.   A 

shaft with a cut-out in it is installed across the mouth of the hollow 

crank which must be where the oil enters/exits the crank.



Thanks for the help all.
