Cylinder Removal: Lycoming

[@edstoro3883]

Finally a video showing solutions when things go bad. I don't know if I have ever done major maintenance where a monkey wrench was thrown into the fray. Thanks for the help!!!

Thank you, very much. I have a Grumman AA1-A with an O-235 C2c. I need to pull #3 for a heli-coil replacement on the upper spark plug. Cheers!

Nice 👍 In the process of looking over my IO-360. Good stuff.

[@fastbackflying853]

What is your IO-360 engine going to power?

[@crazypilot4017]

@@fastbackflying853 I just recently bought a 1968 Mooney M20C, with the motor. The original motor that was in it, had the O-360-A1D, but I did some research and found that you can upgrade to the IO-360-A1A variant. Gonna be a nice project.

[@fastbackflying853]

Wow that will be very nice indeed. I would be very interested to hear what you get for cruise speed and fuel burn. I have 4 Mooney aircraft that I currently look after and a fair amount of flying time in them as well. Do you have electric gear or manual?

[@crazypilot4017]

@@fastbackflying853 still have the manual gear. Ive heard its better to keep the manual because of easier maintenance than the electric…Made a spelling error, on my last comment. I bought the Mooney without the motor, and so I just recently bought a used IO-360.

Thank you for this excellent video.

[@fastbackflying853]

I am really glad you enjoyed it.

Been nice to share "what the scope saw, did a leak- down lead to a valve issue? Will you be doing the valve job/guides hone Or exchange cyl.? Thanks for the looks-see :-)

[@fastbackflying853]

Borescope showed burnt exhaust valve and piston pin plug wear. DCT indicated leaking exhaust valve. We will have a follow up video explaining this along with other details and the installation of the new cylinder. Valve guide was worn beyond limit and bore was also outside tolerance. A new cylinder assembly will be installed.

@@fastbackflying853 thank you for the clarification will look forward to fallow-ups

[@fastbackflying853]

You're very welcome.

[@Arsenal4953]

Seems everything in that motor is tight / siezed.

[@fastbackflying853]

Yes it really is. Very high time engine and old. It's going to be having a serious amount of work done to get it to an airworthy condition again.

[@michaelr2656]

Do you do work on Jabiru engines ?

[@fastbackflying853]

I don't have any experience working on the Jabiru engines.

[@thomassmith5715]

show me the valves

[@thomassmith5715]

thanks

[@fastbackflying853]

What part of the valves are you looking to see from inside the cylinder or them sitting out on the table? I got a small video of a borescope inspection on an IO 550 that I could put up if it was of interest?
