I enjoy learning how things work and go together and really appreciate the knowledge you put out. I'm no pilot but have always wanted to be deep down. I never really had the money and life taking me in other directions. I recently found that Microsoft flight simulator I could not help but get choked up when I finally learned more about how planes are actually operated stuff that I never got to learn or had known but forgot. I had a friend in highschool his dad was an aviation mechanic and wwII pilot he taught me some but never got to go up! Oh God I wanted to so freaking bad! I always kinda had a basic understanding of flight before then but after finding the Microsoft flight sim. it has opened me up! I wish so much that I would have had someone teach me more back then or have this flight sim cause my story and life would be waaay different now the passion to fly burns hot and all I can do is keep the hope alive and keep trying to work and save money and hope that I might at least get to fly a plane at least one time. I hear it cost probably 15-20k to get a ppl. if it can be done cheaper then that I don't really know I'm just going by what someone else said. all I know is if everything I have could get me the money I would need I would probably sell it all.

Check out your local airport and inquire about a discovery flight. You'll get real info from those folks!

In my experience, please change the cam. This series of engine has a history of being hard on cams. Also since your in “overhaul” don’t skimp on parts that can be replaced now like lifters etc. Is this going on an experimental or certified aircraft? Good luck.

@dudleysmith5111 3 месяца назад

Do the different wrist pins types have different weights? If so, could that not cause an imbalance, i.e. vibration?

@HangaRatz 2 месяца назад

400 vs 416 grams each pin

@kaceyd5272 3 месяца назад

Bill, I’m working towards my A&P and these videos are great. I’m looking at helping on an IO-360A1B6D rebuild. Low power is the complaint and we plan on using a dial gage to check the Cam lobes at the rockers to see if the cam is worn by comparing all the intake and exhaust valve displacements.

@shadowopsairman1583 2 месяца назад

Check compression on each Cylinder, leak down as well

@kaceyd5272 2 месяца назад

@@shadowopsairman1583 compressions were fine on all cylinders. Intake cam lobe for #1 & #2 cylinders is only pushing the valve about 1/2 the distance as the other two cylinders. New cam ordered.

@HangaRatz 2 месяца назад

You will probably find that your lifters touching those lobes are toast as well. Be safe!

@jumpinjack1 3 месяца назад

If that is a solid crank like the A4K it is extremely tough from my experience and can take a major prop strike on pavement and still be good, Thanks for the vid :) PS I would still use the primer line if not leaking, very doubtful it would burst into flames, just reposition the chafes.

@HangaRatz 2 месяца назад

Fingers crossed the crank is still good...

@davechapman7735 3 месяца назад

thanks for the interesting info. very well explained thanks. one question please and that's what are the 4 pipes on the sump ? I have seen that they connect to somewhere around top of cylinders ?? Thanks

@HangaRatz 3 месяца назад

They connect the cylinders to the carburetor (mounted on the bottom of the engine) Thanks!

@terryhagle 3 месяца назад

Thanks for the thorough explanation. How far behind in lycoming on cylinders?

@HangaRatz 2 месяца назад

A lot. I heard rumors of them being 80,000 cylinders behind. Does anyone know the current number?

So what is your tbo and at what age should you undergo heart transplant or something?

@HangaRatz 3 месяца назад

Not sure. I think if you need a new heart you may have reached your personal TBO. Then again, your only choice is aftermarket PMA parts... Results may vary!

@crono331 2 месяца назад

@@HangaRatz let me first say i really appreciate your videos and thank you for the time you dedicate to make them which i know is a lot. But from the vantage point of being a airplane user (but only experimental airplanes because nowadays one has to be mad to operate a certificated airplane) there is way too much emphasis on TBO and associated, perfectly round magic numbers. There is absolutely no way one guy sitting in Lycoming offices 50 ot 60 years ago and 10 thousands miles from me can establish how long an engine will last. And there is absolutely no way an engine with 1000 cycles will have the same wear as one with 5000. Also, the notion that an engine with 2000 hours will be less reliable than one with 100 is completely false and demonstrably so. It might have slightly lower performances, thats all. Recently i helped a friend to replace the Limbach engine of his experimental. Engine had a cracked head and broken rings in at least one cylinder. Well, the new engine has way lower compression and lower performances than the old one. Engines wear out and at some stage they will be replaced or overhauled but, considering the costs and associated downtime of these operations, i think is not reasonable to expect that someone throws in the bin multiple thousands dollars just because it is the engine's birthday. The engine in this video shows signs of wear. Hardly surprising considering it has been used. but i didnt see anything broken or so worn out to rule out running it for another 200 hours. And just to put this into perspective, will take me from 4 to 6 years to fly 200 hours.
