Huckster79 Posted May 23, 2023 Report Posted May 23, 2023 On my 2nd training flight we noticed this and headed home to get it checked out. The vacuum gauge needle was rocking back and forth rapidly- I could t post the video but you can see it in the screen shot… Any ideas? I’m going to have my mechanic take a look but I appreciate the community input to maybe head them in the right direction… Quote
N201MKTurbo Posted May 23, 2023 Report Posted May 23, 2023 You should order your new vacuum pump now. You have one broken vane, the rest will follow shortly. 1 Quote
65MooneyPilot Posted May 23, 2023 Report Posted May 23, 2023 Did you just remove any instruments and change where the gauge is reading from? I just removed my last vacuum gyro indicator and mine is doing the same thing. It lost its snuber orifice used to dampen the indicator. I am going to have to figure how to put one back in the system. If not go with 201MKTURBO. Quote

I've come across several, and none of them agree with each other or a calibrated standard. Even new, they aren't very accurate, at least the one new one I tested. 2 hours ago, Huckster79 said: Yessir! It cost me a “I wasn’t using it anyway, take it”. Glad you didn't have to pay for it. 1 Quote
