    Lube the Step

    Co-pilot and I cleaned square step shaft with brake cleaner, then applied dry teflon lube. The top half was pretty dry. We worked it manually several times, and the spring was well behaved. Seems better now. Thanks for the advice to all who replied.
  2. The last few flights saw the vacuum actuated step on my '67C not fully descend after landing. The engineer in me thought "that needs lubed". An hour ago, I would have bet serious $$ that someone had previously discussed ad-infinitum how to do this on MooneySpace. I searched and much to my surprise it did not turn up as an issue... The maintenance manual says "Tri-Flow every 100 hours" but doesn't say how. Before I start spraying teflon-infused oil everywhere, can one of you experienced guys give a relative noob a clue? Thanks!

    Accelerometer

    I had an empty 2-1/2" hole in my panel so I filled it with a GT-50 clock/timer/g-meter/voltmeter. I liked everything about it except one thing that drove me nuts. It has a low voltage warning mode that seems to be its #1 priority. Any time the voltage falls below about 12.7 for about 20 seconds, the thing becomes a blinking distraction. Getting ready to take off, I want to know the time, and it is blinking voltage! Doing my checklist, and runup, that thing is blinking voltage! I already have a voltmeter in my a/c. I took it out and replaced it with a good 'ol Davtron M811B. The AV-20-S will be on my Christmas list.

    M20K Rocket Wing Damage

    I agree- the plastic yield properties of aluminum are horrendous. Wrinkling of the wing skin suggests plastic deformation of the wing, possibly including the main spar. Normally structural aluminum behaves well. But, once aluminum yields and goes plastic it becomes an unpredictable and highly non-linear. Plus the load path changes under plastic conditions due to weakening of the parts that did yield. This means that extreme load may have traveled into connectors or parts of the wing far from the main spar. I'd think of it as an ill-tempered rattlesnake and steer clear.

    Wish me luck...

    Good idea getting sight gauges installed. My model C has them. We checked their accuracy when we calibrated the fuel sending units after adding the JPI EDM900. They are accurate to within 1 gal. They "run out of gas" so to speak and don't really measure anything below about 5 gal so they are not good for the FAA mission of telling you when your tank is empty. In flight we cross-check them with the JPI fuel totalizer and the fuel sending units. I really like them. Another source of data for fuel management.

    Fuel Flow at Full Power

    Hi @PilotCoyote. Thanks for posting this. We'd all benefit from a picture if you can post one. I've never had that part of my a/c torn apart. Thanks!

    Translation what is av-20?

    The AV-20 looks pretty useful. Having a backup AI is appealing. This hits a pretty good price point.
  8. Thanks for the photos. That looks like the original 1960's Garwin? The two shops I've talked to about re-screening both want to test/overhaul and warned me against sending them something that is obsolete. Do you know if parts can still be had for this AS indicator? I'd hate to buy something that turns out to be unserviceable.
  9. Thanks- can you send photos?
  10. The prior owner of my C left me a little flag with velcro straps that says "DO NOT TOW". I strap it around the nose gear.
  11. Hi- I'm looking for a used working airspeed indicator with a range of 40-200 mph for my model C. I suspect there are some sitting on shelves because of glass panel upgrades. My plan is to have it checked/calibrated and re-screened so I need one from one of the 'major' manufacturers that would not be considered obsolete. TAS adjustment ring would be a great added feature. Please PM me if you have one that you would part with. Thx.

    Governor Options

    Two weeks ago my A&P took the Lycoming governor off my a/c and I took it to a prop shop. When I handed it to the technician, the first thing he said was "That's an antique". Not a good sign. As was suggested by MS, the governor was in serious need of rebuild and had several ADs on it. The estimated cost of overhaul was hundreds of $$ more than the cost of a new PCU5000, so we installed the PCU5000. I changed out the studs under the supervision of my mechanic, which took the better part of two weekends working in a hot hangar to get done. Removal took de-greasing and triple-nutting to get the old ones out. I was slow and cautious because I was so worried about breaking them off. Yesterday we installed the new gov. and it works just as it should. I had a really nice test flight late yesterday after Tstorms cooled things down a bit.
  14. Thanks! We're really pleased. I'll finish my instrument rating with this setup. My motivation came from this group.
  15. DONE. Finished installing labels/placards Sunday. Panels cut on water jet $120. Cerecote $50 and a twelve pack. The rest- way too much to mention. Now it is time for a victory lap around a good chunk of the north American continent.
