In my effort to get the family CJ flying, I have a couple more questions.

 

-What is the torque for the spark plugs? I pulled, cleaned and tested them. Anyone know what the gap is supposed to be?

-How much oil is supposed to be in it? I drained the tank, nosecase, strainer, and oil cooler.

-Someone mentioned flapper valves between the fuel tanks and the header tank. The only valve like that I could find in my manuals was a check valve in the fuselage forward of the wing leading edge. Is that something I should remove and clean?

-What is the issue about fuel useage between the wing tanks? I've heard that mentioned a couple times.

 

Thanks in advance,

Steve near Chicago

Good morning Steve-

I've always had great success installing my stock Chinese sparkplugs at 240 inch-pounds, making sure to use Champion sparkplug thread lube and a new copper gasket/washer (Aircraft Spruce has them)upon each final installation. 

Fyi,

Justin, N280NC

Steve,Absolutely no disrespect meant but your line of questions leads me to guess that your CJ is out of conditional (annual).Â  If this is the fact I would highly recommend that you hire a competent CJ mechanic and look over his shoulder while he does the required inspection.Â  He will have the knowledge and the proper tools to do the job.Â  I honestly believe that doing this will save you money and heart ache (not to mention wallet ache) in the long run.

The CJ has fuel vents in the wing tanks located right behind fuel cap as observed from leading edge of wing. If you top off tanks, or fly out of trim, occasionally only one tank will feed and you could run out of fuel with one tank completely full. In flight, check your left and right tanks to insure proper feeding.Â  Remember you might have to fly for at least 30 minutes before the gages come off the peg. If one is not feeding, then fly with the high fuel tank.... HIGH! (cross control flying). Some of us have added additional fuel vents in fuel caps or a more elaborate cockpit controlled venting system. This venting problem or lack of symmetrical fuel feed is NOT uncommon on the CJ.  

P.S 

Find the fuel vent port on bottom of wings, take off fuel caps and blow into the underwing vent. You should hear the air coming out of the fuel tanks to insure there is no blockage in the vent system.

Greg's description of the CJ fuel feeding issue is exactly correct.  His remedy is also correct... simply cross control for a couple minutes and then usually they will each feed equally (or almost equally) throughout the remainder of the flight.  It's a little annoying at first, but just one of those idiosyncrasies of the CJ that you slowly learn to love and accept.  Sort of like your new bride leaving the toilet seat down. 



 The one thing I would add to Greg's post is that he mentioned the vent on the belly...  Located nearer to the left wing slightly forward.  If memory serves, there was a CJ that had an engine failure due to fuel starvation about 10 years ago... due to mud dobbers or some other type bug nesting in that vent.  When I heard that I installed (wrapped) a small wire mesh screen over the vent opening just in case.  So far, no bugs and no vent blockage. You might consider doing the same.

Oops, sorry that was for the M14. Would assume the CJ would be similar.

The generally accepted torque range for 14 mm spark plugs is 20 to 25  lb./ft. or 240 â€“300 lb./in.  Anything above 25/300 is likely to cause  excessive stretching, insulator cracking and plug failure.

Steve, I should have said when you blow thru the vent tube on the lower wing, make sure it is very low 10psi max or less!!! In addition, I would agree with Doug Sapps comments regarding finding a good CJ/ YAK mechanic to go thru the airplane with you or someone that is real familiar with it.

Doug,

 

I take no offense and you are correct. Like I said earlier, the airplane has been sitting a few years and is out of condition inspection. I've been asking around and there doesn't appear to be any CJ/Yak experts in the Chicago area. Lynn Hadler at Lake-in-the-Hills who used to take care of it retired last year and apparently moved to Tennesee. Dave Monroe and the Aerostar guys are training another guy on their airplanes to do their maintenance but he hasn't been around any CJ's. This side of offering you an airline ticket out to Chicago to look over my airplane, I have to investigate other options.

 

That being said, the CJ is is one of several airplanes we have built, restored and operate, ranging from gliders to aerobatic aircraft to other warbirds. I realize that that none of them is a CJ and I agree with your suggestion top have an experienced CJ guy to help out but I haven't had much luck there. I do have some former CJ owners helping out and the airplane doesn't look that complicated, just a little idiosyncratic. I was hoping to tap into all the experience and expertise on this forum to at least get it ferriable or round up enough advice and information to work with the local guys to do it here.

 

Are there any maintenance manuals or condition inspection guides that I may purchase or download? I do have a set of the blue parts books that came with the airplanes.

 

ANY advice is appreciated.

 

Sincerely,

Steve Jones

Steve,

Absolutely no disrespect meant but your line of questions leads me to guess that your CJ is out of conditional (annual).  If this is the fact I would highly recommend that you hire a competent CJ mechanic and look over his shoulder while he does the required inspection.  He will have the knowledge and the proper tools to do the job.  I honestly believe that doing this will save you money and heart ache (not to mention wallet ache) in the long run.

I'd suggest getting the maintenance manuals from the RPA if you don't already have them ...

Doug,

Â 

I take no offense and you are correct. Like I said earlier, the airplane has been sitting a few years and is out of condition inspection. I've been asking around and there doesn't appear to be any CJ/Yak experts in the Chicago area. Lynn Hadler at Lake-in-the-Hills who used to take care of it retired last year and apparently moved to Tennesee. Dave Monroe and the Aerostar guys are training another guy on their airplanes to do their maintenance but he hasn't been around any CJ's. This side of offering you an airline ticket out to Chicago to look over my airplane, I have to investigate other options.

Â 

That being said, the CJ is is one of several airplanes we have built, restored and operate, ranging from gliders to aerobatic aircraft to other warbirds. I realize that that none of them is a CJ and I agree with your suggestion top have an experienced CJ guy to help out but I haven't had much luck there. I do have some former CJ owners helping out and the airplane doesn't look that complicated, just a little idiosyncratic. I was hoping to tap into all the experience and expertise on this forum to at least get it ferriable or round up enough advice and information to work with the local guys to do it here.

Â 

Are there any maintenance manuals or condition inspection guides that I may purchase or download? I do have a set of the blue parts books that came with the airplanes.

Â 

ANY advice is appreciated.

Â 

Sincerely,

Steve Jones

Steve,

Absolutely no disrespect meant but your line of questions leads me to guess that your CJ is out of conditional (annual).Â  If this is the fact I would highly recommend that you hire a competent CJ mechanic and look over his shoulder while he does the required inspection.Â  He will have the knowledge and the proper tools to do the job.Â  I honestly believe that doing this will save you money and heart ache (not to mention wallet ache) in the long run.

I happened to catch some of the comments on the fuel vent but not all. It's a really great place for insects to go live. Many people drill a hole(s) through the tip of the vent and slip a piece of thin safety wire thru to make it a little harder for certain insects to get in there.



Sorry if that's been mentioned already...

Check the guys a finefield [sp?} aviation at lake in the hills.Â  They worked on my Yak-52 a few years back (15+) and were great guys.Â Â  They probably donâ€™t know the CJ, but could work on things with help from remote experts.Â  They do have round engine experience.

Actually there is supposed to be a small screen cap over the vent tube.Â  It is normally held in place by safety wire or a cotter pin.

I have a couple more quick questions.First off, is there going to be a Cj/Yak Forum at OSH?Second, is there anyone around that might be interested in checking me out in their CJ? Of course I'd cover any costs and expenses. I'd like to be ready to go when our airplane comes out of its condition inspection and it's been several years since I flew one.In fact, I'll be at OSH all week and then some. Anyone available up there?Thanks for your time,Steve JonesN76187Near Chicago
