Beautiful plane and engine.........next time.........as you are lifting the cylinder off of the piston , put a rag around the connecting rod under the piston , and tuck it into the crankcase............you never know if a piston ring or oil ring has shattered and as you lift the piston out of the barrel ,, a chunk of broken piston ring falls out and into the crankcase it goes..........fortunately there was no broken ring sections in that cylinder , but you never know the next time...........on the bottom cylinders there would not be such a risk , but on the top ones gravity will pull broken pieces into the crankcase..........when it happens , you will say the F word many times ...........placing a rag in the right spot only takes a minute , and you will love yourself for doing it when three pieces of ring fall into the catch rag and not into the crankcase..........you dodged a bullet that time , but maybe it might happen next time , and it will wreck your day..........love your plane and engine and enjoyed the video.........thanks
Thanks for posting the video, got to see the performance in El Paso, TX last year. Watching you put that aircraft through the routine you fly is still astounding!
Great hands on video,the cylinder fitting shows the juggling act it requires and Kyle made it look easy when really it is not ! thanks for sharing sir.
Sorry to be off topic but does someone know a method to log back into an Instagram account?? I was stupid forgot the password. I appreciate any help you can give me.
@Rayan Braydon I really appreciate your reply. I got to the site on google and Im in the hacking process now. Looks like it's gonna take a while so I will reply here later when my account password hopefully is recovered.
I just saw this and would like to know if you would sell that Lincoln in the garage there? Lucky that's all that went on the engine and you got down safely. Still a B/P raising moment. Cool aircraft too.
That's what I noticed, when he installs the complete replacement cylinder with the housings and the sticks still in place, he has no idea what kind of clearance or negative clearance he is going to have. He could torque it down, put palnuts on all the studs only to find he he hasn't any valve clearance. At this point He may not be able to shorten the sticks because there too long to remove them from the cylinder. All the clearance adjustments are made with the sticks that were inside of the housings. I watched a couple of these cylinder replacements on a 985 and the last person did it just like he did. As if a cylinder replacement isn't also going to require valve clearance adjustments which will likely involve the removal or replacement of a spacer of a different thickness. The valve seats are not going to be the same between the two cylinders and for all he knows one or both of the sticks could be bent. Maybe it's all staged.
That doesn't work very well. You push on the cylinder and the linkrod moves to the side putting the piston in a bind inside the cylinder. Then your only recourse is to pull the cylinder off and reset the ring compressor again.
The reason the piston head came off is because the cyclic loading on the alminium caused fatigue and failure. Expect similar issues on the other cylinders soon.
It was interesting that the failure happened about where the "head" would normally be attached to the cylinder. The head would be the first part of the barrel to heat up during warm up and transfers the most heat to the air during operation, because ignition happens near TDC, and hot gases flow out the top of the head. Thermal expansion of the head may have added to the cyclic loading on the barrel. I wonder if at overhaul they replace the barrels or just recondition. The only real way to know is to examine a large number of engines and their histories. Most likely it was a casting flaw or this problem would have been dealt with previously!
mmmm, those things that holds the attachment of the cylinder to the power section are named nuts...not bolts...one more thing and please don't hate me but leaving the aircraft unattended with no brake rider and the engine running going through the front for leak checks is a way to have yourself kill and put other humans at risk, please that aircraft is to show skills, have a good flight...
The glamorous side of airshow flying. Now I see what makes Kyle's performances so awesome...Hard Work...
luv them old radial engines

KYLE COOL STUFF THANK YOU LOVE ROUND ENGINES.
Thanks for posting the video, got to see the performance in El Paso, TX last year. Watching you put that aircraft through the routine you fly is still astounding!
Thank you for filming this. Very neat!
Beyond awesome! Definitely would like to see more videos like this.
Dude I highly admire you and your history in aviation !
i luv the 3 blade propeller luv it
great video would love to see more like this in the future
I like this kind of video, thanks for the hard work.
There is no better song that the one Radial Engines Sing....Coooooll.........👽👍
Awesome. Great video. Way to keep it G rated

@Rayan Braydon It did the trick and I finally got access to my account again. I am so happy:D
Thank you so much, you really help me out!
@Abram Kaysen No problem xD
Great video, you make it look too easy..... good job!
smooth smooth sounds great
good vid; I'll be getting my own 985 soon can't wait. Great sounding and running engine, very instructional , lets see more !
Well done Mr. Franklin, very good video. keep up the fantastic and inspirational avaition work. Greetings from the west of Ireland.
Beautiful engine!!!!
Very cool video. Thanks for sharing. Take care and God Bless.
The infamous scrapper ring......grrrr sometimes when I'm working on B-18's I wish I had 3 sometime 4 hands to install a jug lol
nice one
I wonder if it had been shock cooled then went pop?
I just saw this and would like to know if you would sell that Lincoln in the garage there? Lucky that's all that went on the engine and you got down safely. Still a B/P raising moment. Cool aircraft too.
Is that an extra set of wings for Drac I see hanging behind you?
Only a question, the new cylinder head cames with their valve's clearance already adjusted from refurbishing/seller ?
That's what I noticed, when he installs the complete replacement cylinder with the housings and the sticks still in place, he has no idea what kind of clearance or negative clearance he is going to have.

I've always put the piston into the connecting rod first used a ring compressor, even for the oil ring.

Hope that circling off the end of the grudge on didn’t drop into the engine (about 4:20)

CreeperOnYourHouse There was nothing wrong with the piston "head". The cylinder head parted ways with the cylinder.
CreeperOnYourHouse the engine TBO of over 800 hours. It could as simple a casting defect in the jug.

@@garybulwinkle82 The barrel cracks where it meets the head.
You must have already determined you wouldn't need to add or remove spacers.
So by bolts you mean nuts?
Whats the squealing noise?
maybe shudder replaced the rings too.
VERY GOOD VIDEO, BRASIL OK.
That’s a lot easier than Continental. The whole exhaust has to come off on Continental.
What about the other eight?
Sheriden Boord what about the other eight?
When they break will get another video I guess lol very cool
Or throttle /pitch / mixture cables beechcraft twin bonanza
R 985 is a breeze show me alternator/generator 0-200
