There is a little bleed screw above the water pump that you pull out to get most of the air out of the RV chamber. There is actually a little casting line in there that will prevent it from totally bleeding the air out. I use clear lines for the oil tubing so I can see if there is any air in the system. On the 3 inverted engines I have done, I have to damn nearly stand the plane on the nose to get all the air out of the engine. Make sure there is no fuel in the wing tank, I chocked the wheels, then lifted the tail over head and tied it off to the truck bumper and let her sit there for about 5 minutes as I watched the air go up the lines into the reservoir. It took several times of putting the tail as high as I could get it without hitting the cowling, then back down, refill the reservoir repeat tail lift etc.

The last Mk IV I did it took me a couple hours of dicking with that damn thing to get the air out.. I would bleed the shit out of it, think I had it, run it up and then see air in the line again.. refill, tail up, watch air, get solid oil, run up, see air, tail up etc.. if I had not used clear lines I would have never seen the air in the lines, and would have thought it was properly bled by using the bleeder screw on the engine block per the manual.

I learned this lesson the hard way on my plane. I rebuilt the engine, new crank etc, put it together, bled the air per the manual fired it right up and thought I was cutting a fat hog in the ass... then about 15 minutes into the break in, she went quiet on me. Turned out there was air in the RV cavity and the brass gear stripped.... Set me back a bit but after that is when I went to clear hose and learned what a bitch it is to get all the air out of the engine on some of the inverted installations.

Forum Idea

On a lot of the offroad forums that I surf they have a Tech section. Whenever a motivated member does some task on their rig they take pictures and then submit a step by step tutorial along with the pics on how to complete the task. Leni do you think we could add a section titled Tech where members could submit this kind of info?

I was thinking of tasks like: Rebuilding a Mikuni Fuel Pump, Bleeding your Rotary Valve, Rebuilding a Bing Carb, Servicing your Gearbox, Calibrating your Altimeter, ect ect Just basic maintenance stuff that some people might be reluctant to do without some good instructions.

Most of these type of tasks have procedures written on the net or elsewhere but they are often vague and don't account for real world experiences that people have had. There are always gotchas that the instructions don't mention when your working on this kind of stuff. What do you think?

Thanks Randy. This engine has had all of its time on synthetic mix oil so I doubt it has very much carbon in it. I had the same plan as you...get my plane flying and get some time on it and then worry about something else. I was hoping to get a little more time out of it than I did. Once it started using Rotary Valve oil on almost every flight I knew it was time to stop pushing my luck.

Leni can you post what procedure you've found that works for bleeding the RV and cooling systems on an inverted engine? The CPS catalog says to consult the manual but it's not in there. I've heard your supposed to bleed it right side up and then flip it over..that would be a pain trying to route the lines and not have oil running out of them all over the place.

The picture of your piston is probably not as bad as it looks as many hours is on it. You may have a slight pressure leak on that cylinder, you definately want to find out before breaking in your new engine.Sometimes the lack of carbon build up results in a carmel colored piston and makes it look lean.Your egt,s should tell you alot though.I would be more concerned with the color near the ring as it looks like the exhaust was running fairly warm.But on the other hand Im a boat mechanic and have never been into a aircraft engine.The new engine should give you a lttle piece of mind.I think I will do what you did and run out my greyhead and get some hours logged on my plane and save up for the newer bluehead.Its got 120 hours on it now so thats alot of flying if it makes TBO.Good luck with your engine transplant.

Mine never run above 1150 on my cheezy little gauge anyways. I have only seen them climb once in the midrange during a decent. I try to either descent around 5K or idle if it's not more than a minute or two of descent so it doesn't cool too much. I'm running the Amsoil at 80:1. They call for 100:1 so I'm already running it fat. My plugs led me to believe that I was running a little rich if anything. The inside of the exhaust manifold and pipe was a real golden color..almost bordering on a whitish color. I will have to be sure and watch my temps very closely with this new engine. I found two more leaks after I got everything off and cleaned up. The old engine is definitely ready for a teardown.

EGT's are a bit high.. Didnt you say you were running the amsoil at 80 or 100 to 1? I cant remember if it was you or someone else that was running it. If so, fatten it up a bit. What do your EGT's look like when you pull the power? they go up a good bit in mid range? I run mine about 1100 tops using mixture and pitch.

I made a little bit more progress tonite. I rebuilt my Mikuni Fuel Pump. Did you know they recommend you do this annually?? In all the two strokes I've flown I have never tore one down till today. The kit is $15 from California Power Systems and it took me all of 20 minutes to rebuild it once I had it on the bench. Here are some pictures if anyone if anyone cares to know what the inside of one looks like. There are two little discs in the very center that use a little rubber plug to hold them in. Put a dab of grease on the new ones or you'll never get them back through the hole. I destroyed the first one I tried and had to re use one.

Rebuild Kit part number

I also pulled my exhaust manifold off since I will be re-using it with the new engine. Anyone care to diagnose this piston for me??? Yikes

The lines on the cylinder wall were VERY visible also

Next up is bead blasting that nasty old white paint off my gearbox and getting it off the old engine.

I bought my Grey Head as a FWF package from a guy that upgraded his B model to a Jabiru. He had rebuilt it twice and it had just shy of 1200 hours total time and 360 SMOH and 6 yeas on it when I got it. I knew it was run out when I put it on but figured I could get some time in on my bird before I did something with it. The rotary valve seal starting leaking after I put 18 hours on it so I started looking at my options. I found a very low time blue head for less than what it would cost me to pay someone to rebuild mine. The guy I got the engine from was even nice enough to tear it down and put all new seals in it, check the crank, and put pistons and rings in it so it's essentially a zero time engine now. I'm sending my Greyhead back to him as a core. This way I'm only down for a week too while I do the swap not a month or longer had I sent it off somewhere.Check out Rotax Rick on Barnstormers...very experienced Aviator and has been building Rotaxs for years. Great guy to work with and always has engines and Rotax parts in stock. Oh ya and no one else I found out there could touch his prices. We'll see how my engine runs before I praise him too much but so far he's been awesome to work with.

Hi, How many hours did you put on your 582 before pulling it out?Are you rebuilding it or buying a new one? I was just curious if you were getting the new blue head style or rebuilding your old one.Its amazing how that little engine does what it does.I have a grayhead motor that Im putting in my Skyraider so hope it works out.Good Luck on your project.

March 2003

I had purchased my Cessna 140 on Feb. 28, 2003. Previously I had been renting 152's and 172's and was quite happy to have my own aircraft. My girlfriend (marriage was still three years away) had ridden down to Soldotna with her sister to visit their parents and I was going to pick her up the next day. She had flown with me once before in a 152 and I was more than happy to put some hours on the plane. This was in mid March. Anybody from south-central Alaska remembers the weather we experienced in March of 2003. And guess who is going out flying!

I depart Merrill Field about nine in the morning and have a beautiful flight down. I have lunch with her family and everything is great. In the afternoon we notice the tree tops are moving around pretty good so I decide that we need to get going before it gets any worse. Her father drops us off at the airport. Of course the wind is anything but coming down the center-line. I make one of my ugliest take offs, but we are airborne and headed home. I can see the Anchorage bowl and it is just one giant dust cloud. Damn. It's not super bumpy at this point, just strong winds, making for slow going. Maybe twenty minutes after take off I am starting to think about heading back but I really don't want to land with that crosswind. Kenai's runway is pretty much inline with the wind, so I figure that if nothing else we'll divert there. But first I want to continue on and see if it gets better. It has to, right?

The 140 indicates 100 mph in cruise. At the time I did not have a GPS but we can't have been doing more than 60 mph across the ground. After what seems like forever we approach the southern shore of Turnagain Arm. I prefer to have 3000 ft of altitude crossing the water. As I started to climb it got bumpier and bumpier. Not just light little love pats on the airframe but rather solid feeling hits. I descend and cross the water at about 1800 feet. By now I have tuned in Merrill traffic. An Arctic Tern had departed Girdwood and made an attempt to land. He went around once and headed back to Girdwood, where he said it was not as bad. I didn't feel like flying along the Arm in such conditions, but Girdwood was an option. And I still had Kenai in my back pocket. It sure wouldn't take long to back track with such tailwinds.

We are now over south Anchorage following the Seward highway north and it is turbulent. About the time I approach the Polaris High School reporting point we have trash blowing past us. Trash bags, paper, all sorts of crap and we're at 1000 feet. My left hand is moving the yoke in, out, left, right, whatever it takes to stay somewhat straight and level. Meanwhile, Sarah is sitting there not saying a word. Later on, after getting safely on the ground, she said she looked over at me and I did not look scared and that was good enough for her.

A Piper Navajo was making an approach into Merrill. I paid attention to the radio. Fuck, he had to go around. If a Piper twin was having trouble, what were my chances? Understand I had well under a hundred hours on my license. I've been around small aircraft for as long as I can remember, but that is not the same as PIC. The Navajo is on final again. I hear the controller tell him to exit the runway and I breathe a little easier. Still, the wind is howling and the difference between his plane and mine is more than a few thousand pounds and I'd bet he had at least a hundred hours PIC time.

I talk to the tower and I'm cleared for runway 33 (it's since changed to 34). The wind is better for the ski strip (runway 3). I tell the tower I'm going for runway 03. I'm on wheels but the runway is solid ice. Either way, the airport, any airport, is a beautiful thing.

Not thinking (pretty much par for the course), I touch down standard-style at the approach end of the runway. It was actually a pretty decent landing. Except I have about 1800 feet of icy runway in front of me before there is any sign of dry pavement. Landing was easy. Taxiing is a bitch. It took me fifteen minutes to get off the runway. It seemed like forever. I would slowly advance only to have the wind blow us towards the edge. I'd throttle up, face into the wind and move towards the other side. We ended up making a sawtooth path all the way up the runway. Finally we get off the runway and onto dry pavement. I start taxiing towards my parking spot. At first it's fine as we're pretty much facing into the wind. But I have to turn onto taxiway Quebec. Crosswind. I had not come this far to wreck my plane taxiing around. It was no fun. I'd be going down the taxiway and in an instant a strong gust would turn the plane 90 degrees. Nothing I could do to prevent it. I'd straighten out, make it 80 yards and again find myself looking into the wind. Then I see a wonderful sight. Two guys come running towards us. They bend down and come up with tie-down ropes. They wave me in. I taxi in between them as they tie down the plane. I swear these guys must have had halos and white wings. I shut down the engine. My airspeed indicator is still active. One of the saints gave Sarah a ride to the car. I sat in the plane and manned the controls until she returned. It is odd to have to fly your plane while it is tied down. I should have logged that time as well! When Sarah returns I notice an upside down aircraft. A Taylorcraft had a tie-down come undone and had flipped over. The two guys go over to see what they can do.

I secure the plane as best as possible and we return home. Waiting on the voice-mail is a message from my little brother: "Nathan, if you get this message, DO NOT FLY BACK TO ANCHORAGE! STAY IN SOLDOTNA! REPEAT, DO NOT COME HOME!"

The next day there is enough of a break to get back to my normal tie down, although it is still very windy. The next day I have to return to work. The wind storm lasts for a few days. My father spends most of one night with his car parked in front as a wind break. There were many aircraft damaged in that windstorm, but mine was just fine.

I still think about this flight and shake my head. I used my inferior judgment to put my inferior flying skills to use, to modify a popular expression.
On my boss's wall is a sign that reads:
Good judgment comes from experience
Experience comes from bad judgment
-Nate

Engine Swap

I got my old engine off and sitting on the workbench tonite. Was surprised quick it went. Got lots of cleaning up to do now. I was never really happy with my wiring. So glad I get to re-do it. I'm also replacing a bunch of line and rebuilding my fuel pump while it's apart. I'm going to bead blast the white paint off my E box before I tear it apart also. It looks decent in the picture but it's peeling in a bunch of spots and just looks like crap overall. I'm a stickler for details. Here is where I'm sitting right now.

Careful what you ask for

After a relaxing bath Monica Lewinsky was looking at herself, nude in a mirror.
Her frustration over her lack of ability to lose weight, was depressing her.
In an act of desperation, she decided to call on God for help.
'Lord.... If you take away my love handles, I'll devote my life to you,'
she prayed.

Alaskan Diaries

HER DIARY

Tonight, I thought my husband was acting weird. We had made plans to meet at a bar to have a drink. I was shopping with my friends all day long, so I thought he was upset at the fact that I was a bit late, but he made no
comment on it.

Conversation wasn't flowing, so I suggested that we go somewhere quiet so we could talk. He agreed, but he didn't say much. I asked him what was wrong. He said, 'Nothing.' I asked him if it was my fault that he was
upset. He said he wasn't upset, that it had nothing to do with me, and not to worry about it.

On the way home, I told him that I loved him. He smiled slightly, and kept driving. I can't explain his behavior. I don't know why he didn't say, 'I love you, too.' When we got home, I felt as if I had lost him completely,
as if he wanted nothing to do with me anymore. He just sat there quietly, and watched TV. He continued to seem distant and absent.

Finally, with silence all around us, I decided to go to bed. About 15 minutes later, he came to bed. To my surprise, he responded to my caress, and we made love. But I still felt that he was distracted, and his thoughts
were somewhere else. He fell asleep -I cried. I don't know what to do. I'm almost sure that his thoughts are with someone else. My life is a disaster.

HIS DIARY

My airplane wouldn't start today, but at least I got laid.

1050, hell yeah! give you lots of room!

on the set up.... I used to use a suction cup mic that I got at radio shack for recording phone conversations. I would put that on the earmuff on the head set and plug it into the recorder. No engine noise, but I could talk and you would hear that clear as can be. All radio conversations were recorded as well.

I have a pre-order in for the HD hero cam. Very small package, and is affordable as well as water proof. It was developed for motor sports so they worked hard to cut out all the wind noise etc. You can do an ebay search for HD helmet cam and they will show up.

As far as learning the bush stuff... The best thing you can do it get in your plane and go to altitude, then get VERY comfortable flying it around at minimum controllable speed with the nose high and lots of power. Once you are comfortable at altitude, and you know how your bird will handle at low speeds in steep turns etc, you can start working on the landings. Pick a spot on the runway that gives you room to set up a good approach and start working on hitting that spot. You are not going to be able to pull the power at altitude and land on the numbers everytime. You will have to use power to keep the elevation and sink rate under control, and elevator to regulate speed. If you keep at it, and make every landing a purposeful event, you will get it in no time. You need to be able to make decisions in an instant. When going into a one way strip, you have one shot at getting it right. If you can see that you approach is not right (even if you still have 3000' of runway in front of you) and that you will not be able to hit at your predetermined spot, power up and go around. You cant push a bad approach into a spot landing! Going full power and going around has to be the first thing that your hands will automatically do when you brain sees that you wont be able to hit the intended spot! Dont do anything you are not comfortable with! Work into it slowly at a pace that is OK with you.

I was very fortunate that my first instructor is an old grizzled AK bush pilot from way back. He has known me and flew our family around for a lot of years prior to me starting to fly. His approach was "the FAA says I have to teach you XY and Z... BULLSHIT, that may work for pavement pounders, but I know what you like to do and how you will be flying" From day one, he was pushing me to pick the lift off spot on the runway that was my decision length.. if I was not off by then, get on the binders, and shut her down before you hit the "pretend" trees on a 7000' long runway (ATC loved us) Same with landing. Those tires better leave marks on or before the numbers or he would firewall it (was allways fun when I was concentrating on getting this biatch on the ground in one spot and all of a sudden the dick weed in the back seat shoves the throttle to the wall)

Take off I like to give it full down. Get the tail wheel off the ground and out of the weeds as fast as possible as it will slow you down with drag. As the tail starts coming up, I ease in the up elevator to keep the wheel off the ground, but low enough to get maximum angle of attack. As soon as the wings are making enough lift she will fly.

Damn my fingers are sore now

There is no sound on the camera itself. Pity.

There's a guy out there called Taildrgfun, he mounted the camera on his gear leg, then strung a small mic into his headset, so that there is some engine sound, yet still allows for some narration through the intercom. I'd like to copy this setup. (Someday...)

The "Strip" that isn't there (yet) is 1050' from the corner of the field to the driveway. I think it is do-able. I do need some more stick-time before I'd try it. However, I need to get the dead soybeans off it and a strip made and planted, first...

Leni-- What you mention about the techniques of short landing are something that I really want to learn. I'm trying to find a source of information to teach me about these aspects of the art of bush-flying. Any suggestions?

Do you not have sound on the camera, or are you editing it out? I would not say they are boring, but hearing that engine scream does add a bit of entertainment to it

I would have a strip in front of that house in a newyork second! How long is that run? Looks to be close to 900 or 1000' twice what ya really need as soon as you start nailing the approach speeds and dragging it in on power.
