Do you have a part number?  I have a carburetor that is suppose to be for the 80 hp Franklin.  It still has the tag on it.    Tim

Thanks Keith,  I agree way too much movement.  I removed the entire aileron push rod system including bellcranks.  All joints had bushing with a little play.  Constructed new push rods using rod ends.  I will post picture soon.  I have not had time to install them yet but will l let everyone know how it turns out.   Tim

Maintenance and Repair / Aileron freeplay
« on: October 14, 2016, 03:07:14 PM »
I have been working on improving a number of minor issues on N 41726, including root fairings, Aeromatic prop, landing gear retraction and fit and general sealing.  After the installation of the Aeromatic I became concerned about slop in the Aileron control loop.  I had noticed that one of the ailerons was flying higher than the trailing edge of the wing.  I fixed the left one centered on the wing and was able to moved the right control surface 3 to 4 inches without any resistance.  This strikes me as way to much free play in the system.  There are 8 connection in the loop from the left control horn to the right, each one has some play between the bolts and the bushing.  Has anyone address this issue with a high time Cadet?  If so what was the solution?  Does anyone have knowledge of a Cadet experiencing flutter of the ailerons?  I am planning to replace all the fitting in the system but would like to know what is acceptable as far as the maximum amount of free play.  Tim

Bill,  I have a Marvel Schebler MA-3 carb.  It does not have a tag but the numbers stamped on it are 17865, 10-2153.  I can send pictures if you are interested.   Tim

Modifications / Root fairings revisited
« on: July 25, 2016, 01:13:34 PM »
I have finally finished installing new root fairing on the Cadet.  I have attached several pictures.  The forward portion is fiberglass.  The rear is a stock Mooney M-20 root fairing.   Tim

Dan,  I just realized that only one of the picture I tried to send you attached.  Also, I should have removed the triangle shape inspection plate to allow viewing of the pitot tube attachment.  On my first Cadet the pitot tube were attached to the center of the inspection plate.  This on appears to attached to the wing rib.  I will take more picture and try sending them again.   Tim

Maintenance and Repair / Re: Landing gear locking pin
« on: October 06, 2015, 11:46:06 AM »
Thanks Bill,  in my first two post I stated that the left link was bent.  It was actually the right side.  I guess I was thinking upside down and backward, nothing new for me.  Anyway I am sure you are aware that the right side leads the left and therefore is the first to be stressed.  Mark Penner has been following along and was kind enough to point out my error.

Maintenance and Repair / Re: Landing gear locking pin

I completed the installation of the new landing gear links this weekend.  Attached is a picture, they work very well with no clearance issues.  In order to determine the side to side play of the strut with the gear extended and the lock pins in place I disconnected the push tube to the lock pin bell-crank. Using the horizontal centerline at the end of the axle as the reference measured 1/8th of an inch side to side of play.  This seems to work very well on my installation.  By moving the gear leg slightly and manipulating the lock pin with my hand I could feel the correct position for the gear leg making it easy to adjust the landing gear push tube to the correct length.  Remember that this is all done on the right side with the left disconnected.  Once the right side was working correctly I readjusted the gear box stop screw and completed the assembly of the left side.  The gear now works very smoothly and with the gear extended while on the jacks the lock pins slip into place using the gear selector lever without any effort at all.  I might mention that previous to this incident the gear had work fine for 150 hours.  I have not determined what might have caused the old link to bend.  We have gear doors installed and I suspect that the additional stress caused by the doors resulted in the links giving a little over time until the right side reached a point that it deflected enough to create a larger bend.  Once this happened the lock pin would be misaligned and would malfunctioned.  I expect that the new links because of the added stiffness will resolve this issue.

Dan,  I am in the middle of repairing/adjusting the gear on my daughter Cadet after a close call a couple of weeks ago.  Fortunately the pilot was persistent in getting the gear selector to engage and was able to engage the lock pins, landing without mishap.  Investigating I discovered that the left push tube was bend slightly where the threaded link exits the tube. I am replacing the links and installing rod ends.  I believe that had the holes in the top of the gear legs not been slightly elongated horizontally the pins would not have engaged.  I will measure the bore of the holes tonight.  I will also try and measure the amount of side to side play in my gear.   Tim

Bill,  I do not know if the recently installed plugs have resistors.  They are old/new stock Champion and called for in the Franklin service manual.   Tim

Maintenance and Repair / Sparkplugs
« on: September 09, 2015, 05:22:28 PM »
I was noticing that my Franklin powered Cadet seem to be down on power.  I had Champion REM 38s installed with 160 hours on them.  Mogas for fuel.  After checking mag timing and verifying that the throttle was opening all the way I changed plug to C10 S.  The power is back and the engine is running smoother.  I would like to hear if anyone has any opinions as to the expected life expectancy of sparkplugs in the Franklin engine.   Thanks, Tim
