For 100K, one can have both. -------- warbird and lover of all things that go fast and upside down!

These restrictor plates are about the size and shape as a contact lens and have a very small hole in the center. It is real easy to undo a gear line and have it fall out and never notice it. Many times they stay tucked inside the b-nut so you have to tap it to get it loose or take a look in to see if it's there (and maybe gunked up.) I know the parts book references it a shock absorber or something similar , but I don't believe there is a picture. Doug sells blank plates and will provide you with a nominal hole size to drill. The hole size can be changed to increase or decrease speed of retraction/extention Read this topic online here: http://forums.matronics.com/viewtopic.php?p=451380#451380 ________________________________ Message 4 _____________________________________ Time: 12:23:59 PM PST US Subject: Yak-List: Re: Nose ear hard retract/fail to retract From: "altman51" I have some restrictors from Doug...will look to see if II need a new one there...thanks for the reply!

Did you get it on jacks as Dennis suggested? It appears you are experiencing two different problems, likely from the same source. First: "nose gear would not retract". Second: "nose gear retracted hard". The first (gear wont retract) is usually due to internal failure of the (firewall) check valve allowing main air pressure to leak into the emergency side pressurizing the down side of the actuators. But since your problem is nose gear only this likely does not apply. The second (nose gear retracted hard) is totally opposite and indicates zero back pressure in the actuator. All I can think of that could possibly malfunction to both situations is the nose gear emergency valves. Both should be tested and probably disassembled for corrosion inspection. If you find something nasty here you should consider the rest of the gear system. The air line restrictors are not the problem. Walt -----Original Message----- From: altman51 Sent: Sunday, December 13, 2015 1:08 PM Subject: Yak-List: Nose ear hard retract/fail to retract The last couple of flights in my CJ the nose gear has "hard retracted - slaming into the gear well. Yesterday when I took off it would not retract. Air pressure was 40ATM. Post was up lights indicated it was down. Both mains retracted normally. Recycled gear down, then up the mains went down normally and when retracted the nose retracted "hard". re-extended, all gear extended and landed with no problems. Any experience/suggestions?
