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

Dan,  here are the pictures of the pitot tube on my Cadet.   Tim

Dan,  I will take some pictures of my wing this weekend and send them to you.  Tim

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.

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,  here is a picture of the push tube.  Bottom one is from the left side.

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

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

Nice job Dan.  What are the toggle switches for?   Tim

Bill,  the serial number on the wings of my plane were stamped on the end of the main spar.

Culver General Discussion / Re: Oil pressure on Franklin 90
« on: August 10, 2015, 12:02:25 PM »
Thanks Joe.  We pulled the oil pump again and shimmed the plunger with two washers.  I am now showing 33 lbs. at idle.  I am now convinced that the low reading is due to the location of the oil pressure pick up port being place downstream of my oil cooler and filter.  I have ordered a couple of fitting so that I can cap off the oil distribution block and bypass the cooler and filter.  I will be able to read the pressure directly.   I expect it to read higher the 45 lbs.  If its does I will feel confident that the issue is resolved.

Thanks for the input Joe.  Does your installation include an oil filter and/or oil cooler?  I have both on my engine and we are beginning to suspect that pressure is reading low because the oil pressure gauge pick up port where the oil returns to the engine is down stream of both. 

Culver General Discussion / Oil pressure on Franklin 90
« on: July 30, 2015, 08:00:13 PM »
Hi everyone,  My daughters Cadet is powered with a Franklin 4ac-199.  It has 157 hours since MOH by Winfield Aviation in New York and runs really well.  The issue I am having is low oil pressure.  It shows 22 lbs at startup and increases to about 25 lbs as the throttle in increased.  As the temp. reaches 160 degrees it falls to about 18 lbs.  and stays there.   I have had the oil pan pulled and check the screen.  No debris of any kind.  Replaced the oil pump gears, plunger and spring.  Changed oil to Aeroshell W100 a little better but still under 22 lbs at idle.  I replaced the gauge prior to all of the above to make sure the gauge wasn't at fault.  I would like to hear from anyone that has similar issues and if they were able to cure them.   Thanks, Tim

Bill,  you may remember that Mark Penner is looking for the elevator trim mechanism for his project.   Tim
