- In this video I take a look at installing cylinders on an O-320 Lycoming engine.
This video is meant for infomration and interest. Installing a cylinder on an aircraft engine is a very important job in terms of deciding when its time to change a cylinder and ensuing that the job is done correctly and in acordance with all mainteance practices, airworthiness directives and service instructions. This video does not cover all aspects but I hope it will provide an interesting look into the process. - Auta a dopravní prostředky
One of the most beautiful videos that explain the installation method, very simple, full of information, no disturb or music inconvenience or crowding. Borrowing the place and several parts this is the most important. Thank you for this wonderful video, one of the most
beautiful views and explanation for Pilot and ownership please keep making these videos with all these simplistic techniques with full of information Thank you so much
Really glad you enjoyed it.
Another turbine guy stopping in for a piston refresher. Thanks for the video. I like the automotive ring compressor.
Yea I really like how the automotive one works. Obviously its no good for getting rings under the piston pin but lots of engines dont have that.
At there prices I thought they would be made of gold. But thank you for letting us know how this is done. But aircraft mechanics are worth their weight in gold. Happy flying.
Yes and this is a cheap engine to fix! If you have something like a Continental IO-360 cylinder prices are an extra $1000 each and you have six to deal with!
Glad you found the video interesting.
Great video. Been a long time since I replaced a cylinder, been working turbine engine to long, and wanted a refresher. One thing I noticed on the video is that you did not install the piston pin caps on the #2 cylinder in the video, the ones that fell when you took it off. Thanks for the video.
You were paying close attention. The new piston pin assembly is a one piece design so no seperate caps.
Great video! Thank you. As for the pushrod tubes, I would have cleaned them. 🙂
Yes i agree but you have to follow what the customer wants sometimes otherwise you end up with some unhappy individuals. Ugly paint on a push rod tube is not an airworthy issue!
18:09 Are the through studs free-floating within the block (without friction)? If so, then a wrench on the far nut ensures equal torque on both nuts, and equal tightening on both sides, even with only one of the nuts oiled.
If not (i.e. friction requires the stud to be hammer-drifted through the block) then the torques and axial clamping loads on each nut are somewhat isolated and independent. Via hysteresis, stud-to-block friction could allow the far nut to not fully regain any clamping it loses during removal of the near nut. Therefore, you would need to oil and retorque both nuts sequentially, with one torque wrench and one standard wrench. Otherwise, you could oil and simultaneously torque both nuts, if possible to use two torque wrenches.
To ensure that both torque wrenches click, you might have to mildly overtorque whicever torque wrench that clicks first. This is especially true, if the stud-to-block friction is low.
This is awesome. I'm an o320 owner who just ok'd a cylinder going to a shop so this is cool to see. About how many hours on average for removal and install do you think? Not doing new pistons in my case.
good job
Greetings! Excellent videos, well put together. I've enjoyed them and appreciate your no-frills approach quite a bit. Thank you for the effort you've put into them. At 7:18 in this video, the overlay mentions "See my video on checking piston rings". What is the title of that video on your channel? Searching for "piston", "rings", etc., doesn't seem to yield a result. Thanks again!
Sorry in the delay in my response.

I didn't give it a very good name apparently!
I am glad that you have found the video helpful.
@@fastbackflying853 Hey that's all good! I appreciate the reply and the content.
Really informative video and well produced. Where are you based and do you travel to help people out with their own engine issues?
Thank you very much. I am based at CYPQ and yes I do travel.
Good video 👍
Interesting that you have to replace the push rods to get the correct tappet clearance. I wonder if that’s a Lycoming thing, or just in aviation. When I worked at a motorcycle dealership, we just replaced or changed out shims to get the correct valve clearance. Or adjusted the length of the push rod to get the correct clearance.
It is certainly common in aviation and the only way to adjust the length in the Lycoming engine is with the different length push rods. Unfortunately this check seems to be rarely done and I have found numerous cylinders with push rods that are too long or too short. I even found one recently on a small Continental engine in an Ercoup that was fresh out of overhaul and had a push rod that was too long!
What keeps the connecting rod piston pin from sliding out and scoring the cylinder walls?
The ends of the pistons have an aluminum cap and that rides up and down the cylinder and stays centered
Owner break in I assume ?
Actually it looks like I will be doing the break in flight in the next week or whenever the weather and insurance are sorted.
Force, not pressure.
An almost pretty good video. Except. Pulling the lifters out of the case. NO MAGNET!!!!!! NO NO NO NO NO MAGNET. Again NONONONO. If you magnetize the lifter, Lycoming wants you to throw it away and purchase a new one. Ouch!
I use a hook made of stainless steel safety wire to pull the lifters.
@@fastbackflying853 I understand that. The next person trying to pull the lifter will try to use a magnet. Much easier than the time you spent fishing. Unfortunetly Lycoming knows something about NOT using a magnetized lifter . So...a word of warning to beginners. You could ruin your engine.
