Sometimes this is corrected via a shim between the wheel and the gear. I've bought these for Cessna gear and they sell for ungodly amounts of money - $100 per pair for used shims. From my experience with Cessna spring gear you can push the aircraft forward or backward and see the gear either spreading or coming together. Where are your tires wearing? Inside or outside? This will tell you if it's toe-out or in. I think they wear on the outside for toe-in and inside for toe-out (someone correct me if i'm wrong). [quote="g.hendricks(at)sbcglobal."]Hi All You Yak Experts, Dont laugh out there, but I just bought a YAK-55M, having little experience with YAKs & M-14Ps, and am not an A&P. I have read all the manuals, and have tons of questions for which that Id like to get opinions & answers. So here goes the first installment: TIRES 1) Tires The previous owners used retread 400x150 tires from two different US retread suppliers. >From the logs the current set have 64 landings and my judgment says they need changing. The previous set of retreads were changed after only 39 landings. The wear pattern is completely smooth on one half and almost full tread on other half the tire. Whats the usual number of landings you folks are getting out of tires (new or retreads) and what gives with the YAK-55 wear pattern? Is something out of adjustment or is this just the way they wear with spring gear. The book says the tires can be turned around which implies they wear more on one side than the other. 2) New TiresI decided to start over with tires and bit the bullet for new tires from Desser. I bought Aero Classic 6 ply 400x150 which were the only tires that size I could readily find. When they arrived they seem to be the same as the retreads except they are at least 1.5 inches narrower tread width than the retreads of the same identical size. So whats the deal with the difference in size ? When I mount them and inflate themcan I expect they will expand to a comparable widthor is there something basic Im missing about tire sizes ? 3) Tire pressureThe YAK-55M manual says inflate the tires to 3.0 +0.5 KF/CM2, which by my calculation is ~42psi, max 49psi. However, the new Desser 6 ply sidewall data says to inflate to a maximum of 30 psi. There is no inflation data on the sidewall of the retreads. Is this because Russian tires are 4-plyI tried Desser for an answer and they dont know. 4) Tail wheel pressureThis airplane has a 200x80 tailwheel with a tube, and the Russian manuals are absolutely silent about inflation pressure. Cant find any data for a 200x80, but 30 psi seems to be about rightwhat are the rest of you folks using ? OPERATING LIMITATIONS 1) The markings for operating limitations on all the instruments are falling off and need replacement, which I thought would be straight forwardnot so. The FARs are clear with respect to the airspeed indicator (redline, yellow arc and green arc, etc.), but totally ambiguous wrt to the other instrumentation. After looking at 7~8 cockpit photos of YAK-55s, YAK-52s, and a bunch of Sukhios one thing is clearno two are alike in the way the operating limits are marked. Anybody want to venture an opinion as to how to properly mark the Oil Temp, Oil Pressure, Fuel Pressure, and Cyl Hd Temp., Etc or is this totally my choice under Experimental Exhibition ?

Get some graph paper and scale it appropriately, then draw a straight line from the point of max weight, max pressure to 0/0. Find your plane's weight on the graph to see what your correct tire pressure. ----- Original Message ----- From: g.hendricks@sbcglobal.net To: yak-list@matronics.com Sent: Tuesday, August 22, 2006 9:00 PM Subject: Yak-List: YAK-55M Tires Hi All You Yak Experts, Don't laugh out there, but I just bought a YAK-55M, having little experience with YAKs & M-14Ps, and am not an A&P.

I think I have seen Kevin's version too, but I am not totally sure. All of them used an electric pump to pump the oil out of the lower sump and back into the main oil tank. Les Crowder's version also used special valve covers with rubber hoses that allowed all the oil in the valve covers to flow back down into the sump as well. All of these systems worked extremely well, but Les Crowder's version added so many hoses and clamps that it just scared the "B'Jesus" out of me due to the possibility of a clamp letting go and oil going everywhere.....on the bottom of the aircraft where I could not see. That said, Kevin's oil shut off valve is the one real answer that works like a dream. I do not have it on my aircraft but I have seen it on three others with M-14's and it is the "real deal". This valve is installed just downstream on the main oil feed. Shutting it off directly after flight means that NO oil is going to run down into the engine through the oil pump ball check valve, and NO oil is going to end up causing a hyd. lock on your lower cylinders. If you also scavenge your engine properly before shutdown, it is my opinion that you can also live without the electric oil scavenge pump itself, but I would defer to more expert opinions in that regard. Again, the oil tank shutoff valve is the real solution, but of course it comes with a danger. If you forget to turn it on before starting... Bye bye engine. Kevin's valve has a built in electric interrupt switch that you can use to interrupt your start system, but nothing is foolproof. I am not sure if Kevin's system includes the hose fittings or not.... But regardless his system is the one I would want.
