  1. Reserve fuel sump

    I am in need of a serviceable reserve fuel sump that mounts on the firewall. Any leads would be appreciated. Ron Ruble iflypby@aol.com
  2. Prop hub nut and snap ring

    As I had to retire my light Kinner Prop and Hub, I am in need of an Air Corps Propeller hub nut and snap ring. Thanks, Ron Ruble iflypby@aol.com 1-407-496-8591
  3. What pitch Propeller?

    I am having Sensenich make me a new Propeller since my old light hub failed NDT. The choices in pitch are -86, -88 and -90. My old prop was a -86 and it did just fine but I would appreciate your feedback on how the different pitches perform on your aircraft. Takeoff run length, ROC, cruise speed, engine cooling, etc. Does any one know if the STC held by the Ryan club for the Sensenich Propeller includes the W90HASP-86 prop? And, does anyone know how to get a copy so the STC can be utilized? Thanks, Ron Ruble S/N 1579 N15550 Since the restoration of 1579 is 90% complete, I only have about 75% left to go!
  4. Heavy Propeller needed

    Looks like I might need to retire my original light hub and Propeller. I am looking for a heavy wooden spinner prop (5.250" thick at the hub) with metal Propeller cap that is airworthy or able to be repaired by Sensenich to airworthy status. Thanks, Ron Ruble 1-407-496-8591
  5. Prop bolts

    I finally found the reason for my confusion as to the prop bolt lengths. There are two Propeller hubs for the Sensenich Propeller, the earlier "Kinner" small hub and the later, larger GFE hub. The Propeller using the earlier hub is approximately 4 inches thick at the hub and the larger hub is approximately 5 1/2 inches thick. That is the reason for the longer bolts. The later GFE hub is also used on the Stearman. The Stearman installation uses longer bolts. The GFE hub requires special nuts along with the special bolts. The thinner Propeller will not fit on the later GFE hub. I have the earlier "Kinner" hub assembly and Sensenich wooden spinner Propeller on my Ryan. I am looking for a drawing of the early hub assembly so that I can determine the correct bolt, washer and nut assembly to use with the "Kinner" hub. Does anyone have the drawing or any suggestions as to where I might source this information other than the San Diego Museum? Thanks, Ron
  6. Prop bolts

    I am in need of eight 41B2329-9 bolts for the short Air Corps hub on the PT-22? These are special high strength bolts with rolled threads. I believe that someone had these bolts manufactured a while back. Does anyone remember who had them made or have a set of serviceable bolts for sale? Anyone else in need of these bolts and would you be interested in sharing the cost of a new run? Regards, Ron Ruble 407-496-8591
  7. Fire Extinguisher

    The parts manual calls out a "la France or equivalent". Not much help there.
  8. ST3KR Elevators

    The Ryan overhaul instructions allow elongated holes in the elevator connect tube and elevator spars to be drilled out to the next size, not to exceed 1/8 inch larger diameter of the original hole size. Make sure that the new hole is drilled concentric around the original hole center line. Regards, Ron
  9. Brake master cylinders

    Skybound is the current certificate holder for these brakes. They have what new stock is available. When you rebuild the master cylinders, make sure that the chain is the correct length or you will not be able to bleed the brakes. I believe the "at rest" gap is 5/32" but check with Jim to verify that. 6910 "A" Buford Hwy Dorazille, GA 30340 1-770-446-6797 Jim Greene, owner Regards, Ron
  10. Vertical fin crack

    During inspection, prior to covering my vertical fin, I found a crack that runs completely around the circumference of the rudder post at the landing wire attach hole. Just the leading edge tube and the fabric holding it together. Make sure you take a good look when you have the parts opened up. Fin shows no evidence of prior damage. Ron
  11. Before I order manuals from ESSCO

    Thanks Joel! I have the original paper manuals but hate to run the chance of damaging them in the shop. Regards, Ron
  12. Reviewing the Ryan rigging manual, there is a statement to use SPEC X bolts in the stub wing aft spar attachments and NOT standard AN bolts. The parts manual calls for WS-58-XXX bolts in this area. SPEC bolts can be higher or lower strength or close tolerance bolts. I cannot find a reference in any of my Ryan manuals or the aircraft hardware manuals that I have for the specification for these WS-58 bolts. Does anyone have a print or reference for these bolts? I wonder how many Ryan's are flying with standard AN bolts in this location? Might be worth a look to see what you have installed. You can see the upper bolts from inside the aft cockpit with an inspection mirror and a light. Ron
  13. PT-22 Paint Schemes

    Although common knowledge seems to suggest that there were no markings on the Ryan PT-22 other than the official paint scheme and buzz numbers, looking through the issues of "Propwash" from Sequioa Field, they actually applied different colors to the front cowls on some aircraft. I have a picture of a Sequioa Field PT-22 that has a yellow cowling. I am assuming my personal aircraft was painted to match this aircraft. When they removed the red ball in the national insignia in early 1942, it appears that they also painted the rudder yellow or in some cases silver, to remove the red stripes. Red was not a healthy color to have on your aircraft in those times. These rudders also had the new dope codes applied. This appears to possibly be a field modification. Not sure why Mike did not paint the national insignia on the bottom of his wings. He might have known that they did something different in the field. Propeller spinners seem to have remained silver as the props were probably changed out on a regular basis and they would not have taken the time to repaint them. Hub caps, propeller spinners and air intake scoops were usually left off to facilitate the daily maintenance requirements. A few later aircraft are all silver with standard star and bar national insignia with no buzz numbers on the aft fuselage. These are few and far between. I see no special paint schemes on the pitot masts. All pictures that I have show them yellow on yellow winged aircraft. In practice, making the pitot mast stand out might not be a bad idea. I have not figured out the reasoning behind the buzz number sequence. Common practice in the AAF was to use the last three numbers of the military serial number, i.e., 550 for 41-15550. With the Ryan's, it is unusual to see an original picture from Sequoia with a "high" buzz number such as "550", although I have a picture from Eagle field with buzz numbers in the three hundreds. I would love to hear from someone with additional information. They might have just started with "1" on the first aircraft assigned to the field and numbered them in sequence. This would appear to be an unusual military practice, but again, I see few high buzz numbers in the issues of "Propwash" that I have. Does anyone have class books from another Ryan contract school that might shed light on paint schemes used there? Regards, Ron N15550, ex N441V
  14. Sequoia AAF Propwash

    On the internet there was a site that had several copies of the Sequoia AAF yearbook "Propwash" available for viewing. I cannot find it now in any search. Does anyone have a link to this site? Was great to research aircraft paint scheme's. Trying to determine when the red ball was removed from the national insignia and when the "stars and bars" were applied. I know the dates that the orders were issued, but does anyone have an idea when they were normally accomplished? During inspection? When a component, i.e. wing was replaced? I have pictures of all three insignias, but the pictures are not dated. Thanks, Ron
  15. Tire pressures

    Barry, Service instructions are 19 PSI for the mains. This is for the Shinn wheels with 6.00 X 6, four ply tires. Not sure what the Firestone wheels with 7.00 X 6 low pressure tires require. I doubt if there are any of those flying anymore. One of the experts might chime in with pressures for tires with more than four plys. Regards, Ron
