As an old AF recip engine mech dealing almost regularly with R-4360 and R-3350's on Old Shakeys and Super Connies ,a cylinder change on a 985 would be like making spare change for some good cigars. Some of the worst to deal with was lower rear on an R-2800. I liked working on the little Beaver that was used in the Aero Club occasionally. The 115/145 fuel was great for the Zippo lighters😁

It's my understanding, the massive Cyclone R3350s were a true nightmare to work on. First used on B-29s that had severe cooling issues, the problem was never really solved. Then when they decided to use the same engine on DC-7s, the nightmare continued. Apparently L1049 Constellations ran a little better? I had a friend of mine that cursed DC-7s based in Alaska.

white zebra Under the right conditions its cruise speed was in excess of 300 mph. It was not for the novice twin engine pilot, however. It is a hot rod in the sky. Other manufacturers produce such planes today. I believe it was a Piper single engine speedster that killed JFK junior his girl friend and her sister on the east coast. It isn't just the speed in flight but the planes of this type are set up differently and require a good number of hours flight time with a pilot skilled in the ways of these performance GA aircraft. They are less forgiving of clumsiness, so knowing what to expect next and being prepared is the game you must play when you strap in for your first solo flight. Except for ex military fighter pilots the average high time twin engine pilot still needs at least ten hours of instruction in the Aerostar before taking off, even then the plane demands your constant attention and intense focus. It is not a walk in the park. There are a number of holes in the ground filled with Aerostar parts.

@nizexlizzy3 жыл бұрын
Same basic concept but a radial connects the crankshaft to the cylinders via a master rod where everything connects to it and then via a single connection it connects to the cranks shaft. The cylinders all burn and move in the same way though as do the valves. Also radials always come in odd cylinder counts where cars are typically even. This is due mainly to evenly spacing things around the engine versus balancing side to side. Very simple explanation but hopefully helps understand it.

To one question in thread: The master rod is made with piston pin end as common and dual sandwiching plates on the other end so all the other crank pin ends are attached to it. Removal of master cylinder requires locking the master piston rod in the TDC position or other piston rings will move below the cylinder skirts and then you'll prob be removing 2 or three other cylinders to fix that problem.
@jash74012 жыл бұрын
There's a tool you can bolt on to a few cyl. holddown studs where the main cases split that will prevent the master rod from deviating from the centerline of its travel. This is accomplished with a dummy piston pin which will slide up and down within a rail the whole length of its travel.

The R-985 is a 60-90 year old engine and the cylinder heads can only be overhauled so many times before they fall out of allowable tolerance to be used. They're so intricate that the only way to salvage jugs that don't have significant issues (like cracks) is to use an expensive spray metal process to rebuild the inner diameter and re-bore it to spec. In smaller P&W engines like this, the jugs are cast aluminum, but in the larger engines like the R-2800 and 4360, the jugs are drop forged. The only price I've found for an overhauled cylinder head for this specific engine is $5400. The rest is "call for price", which means that it's even more than that or not available.

Ties, lacing, and straps are used to secure wire groups or bundles to provide ease of maintenance, inspection, and installation. Braided lacing tape per MIL-T-43435 is suitable for lacing and tying wires. In lieu of applying ties, straps meeting Specification MS17821 or MS17822 (STRAP, CABLE, ADJUSTABLE, SELF-CLINCHING, PLASTIC, TYPE I, CLASS 1) may be used in areas where the temperature does not exceed 120 C. Straps may not be used in areas of SWAMP such as wheel wells, near wing flaps or wing folds. They may not be used in high vibration areas, where failure of the strap would permit wiring to move against parts which could damage the insulation and foul mechanical linkages or other moving mechanical parts.

Paul Crumley Ok, So here is a question (and I am not arguing, just asking). I recently installed an engine monitor on the Lockheed. The wiring out to the engine compartment I tied with string. However, once I got into the engine compartment I could no longer tie anything due to physical constraints. The only thing I could do was get wire ties in as many places as I could in an attempt to keep the wires from moving around and to keep them away from the exhaust and plugs. So if I were to take this to heart, how on earth would you secure these wires? I’ve seen engine monitors and a lot of engines and they were ALL secured with wire ties. I don’t disagree with what you’re saying but just don’t know how you’d accomplish that practice 100% of the time. Those books were written when there were no engine monitors and few electronic devices compared to today. I’m sure our wire ties are probably better made than years before and we all know our government is extremely slow to adapt to changes. I am not an A&P and I do try to clamp things as much as I can, but sometimes there just isn’t a good way to accomplish it without completely removing the engine. So I keep an eye on everything and replace anything I see as needing it. I also work with a number of A&P’s and IA’s and like I said, I’ve never seen a wire tie fail. Perhaps because they are being removed so often to fix something they’re in front of. :-) Thanks for the great information and if you have any suggestions on how to never use wire ties I’m all ears. Also, like I said, I didn’t install any of the ones you were looking at anyway. :-)

You know what is funny. I’ve been in aviation since I was 10 years old and watched mechanic after mechanic drop shit. But you guys sitting in your chairs are so damn perfect you’ve never done a single thing wrong. It is amazing I’ve never witnessed such greatness. What airport did you service with such awesome care and abilities? I realize I did make a mistake and I won’t do it again but I also realize you’ve probably done 100 things dumber in your life. So suck it up and watch something else. BTW: There are other videos on youtube with people way smarter than me doing the same thing. They just didn’t drop theirs :-)

I couldn't tell you how many pushrods I dropped, let alone pistons and I never had a repair I performed come back after a good runup.

If he dropped one into the engine doing that it would be a hard lesson learned.

This is a normal problem with a Chrome Cylinder. during the chrome process the acid soaks into the area between the head and barrel. In time it will blow the head off! This is Normal with Chrome jugs! A normal cylinder change is only about 3 to 6 hours if the parts are on hand! No big deal. You make it sound like this is brain surgery! It is NOT it is normal maintenance on a round engine! Shit I'm glad I'm old and don't have to put up with owners like you!

lol, I guess I'm glad you're old too. Not sure how I made it seem like such a big deal though as I've changed a lot of jugs. As for the leak it is rather rare to get a leak like that as I'm the only one out of 10 Beech 18's around me that have ever seen anything like it. But the process of changing the jug wasn't a big deal at all. Hope you don't stress yourself out over such petty stuff and sorry the video offended you. Oh, and glad you're not my mechanic :-)

Why is it that some not all old AM or any. Old EM come to that think that it's Ok to run a person who is trying to do their best to pass on some info // knowledge on to maybe the less knowledgeable among us , so that we will learn how to spot / look after / and by doing so maybe prevent a accident or a expensive repair bill , even though I am not a aircraft owner or AM I have found videos like this very informative and enjoyable to watch , so may I respectfully suggest that you go back to sleep and dream of yourself when you were at the top of your trade and keeping all that knowledge to yourself , night night

I've encountered cylinder heads blown off cylinders and stuck in the cowling.
