I reached out to Mooney and received this reply: Hello Albert, This is from my Electrical “These are all 3AG fuses. These are "fast acting" fuses, but are neither fast or slow blow. They're considered medium or normal blow. The differences between the 3 have to do with environmental and other factors that are not pertinent to our usage, therefore we do not specify a particular one. Any of them are acceptable.” Littelfuse 311 Series 10 A Cartridge Fuses – Mouser I checked Littelfuse and found this out while talking with Mooney. Neither Mooney nor I couldn’t determine what the Q meant. I did find out that 312/318 series is fast-acting. The 313/315 series is the Slo-Blo type. The 31101(0)Q might specify which series.

To further explain what happened. I didn't blow a fuse. I was going to check the fuse because I didn't know how old it was and wanted some spare fuses to have in the airplane. When I opened the fuse holder, I didn't realize it was under enough spring tension that the fuse launched itself never to be seen again. I then opened the other fuse holder and read the 250v @ 10A, noting it was also the slo-blo type. I went to the parts manual to look up the part number. That is where the Q on the part number came into question. This was simply a matter of checking something done before I owned the airplane and ensuring it was correct and having a few spare in the airplane. For all I knew, the fuse could have been 50+ years old. So, onto this great forum for answers for all to benefit from.

The fuse was a 250v@10A slo-blo question the 250v value.

I have to replace my shunt fuses. The part number is 31101Q, 10A. What does the Q stand for? What is the voltage? The retainer part number is 155020A. Does this number determine the length of fuse? Littlefuse isn’t any help. thanks! albert

An investment firm....enough said! Look what happened within 30 days after an investment firm bought Hartzel...50% price increase.

Is there a trick to putting it on? Any special tools required?

I learned to fly in a 57' M20. 150hp lyc. Family owned it more than a decade. back in the 60's- 70's

Going from memory here...isn't there a difference in the type of solenoid for the starter and the one by the battery(power relay)?

you might disconnect the wire to the starter from the solenoid. This way the starter won't engage and you can listen for the SOS to buzz. If it doesn't buzz, open it and clean the points. You can also check the SOS with the engine timing.

I spoke with a representative from Kaman (Cleveland) who called me a few days ago to discuss the nut and the part number. When I mentioned the torque spec for the nut, he said it was for the steel, self-locking nut. However, when I mentioned the part number was superseded to a common elastic stop nut, he didn't know the nut type had changed. The price range is from over $12 to $0.50 each depending on where you buy.

So, these torque values are for nuts only, not elastic stop nuts, correct?

I guess I haven't looked, and having a senior moment I can't remember at the moment, but are the nuts that hold the hub halves together elastic stop nuts or just nuts?

Where can I find the 2023 AD list and service bulletins? thanks!

thanks Hank, I'll begin the search!

Is there a drawing showing the locations of all the grease fittings on the landing gear?

The manual mentions once capacity falls below 85% on three tests, its time to replace. 5-0171.pdf

Thanks for the replies. The sag test will be part of my starting checklist going forward.

I have had my battery on a battery tender since it was new when in the hangar. The battery tender cost more than the battery back then. That was seven years ago and the battery really performs well when starting that difficult IO360 A1A engine after it has been at flight temperatures to this day. I've never had a battery last this long so I'm a bit nervous. Has anyone ever used a battery load tester to see how much capacity their battery still has after five or more years? Is it even a valid test to make? thanks!

The filters for the Brittain system can be any of the below Fram filters. The physical sizes are all the same, the filter media is the same. The difference is if there are clamps supplied, what type, and if the end is barbed or not. The G12 is just a filter, with no clamps or hose, and costs the most. These prices are current at Blain's Farm & Fleet. albert

Does anyone use an inner tube with a 70-degree stem on their main gear? Were you also able to keep the dust cover on without a conflict between the two? This would be the type of dust cover that uses only a center screw for attachment. thanks! albert

I'm shopping for advice about the digital torque gauge. I have and use the click type (boring), however lately I have had situations where a digital torque gauge would have lessened the strain and fun of owning a vintage Mooney. So, "What are ya'll using?" I mean, when your hands are up in the wheel bay elbows deep and you're too old and not as flexible to get your head up there too, wouldn't you like to have something that hums, vibrates, and rings when you approach and then hit your set value? Kidding aside, take a moment to brag about your tool.

Hopefully, this helps complete this thread, it’s been a good one. I received the spacers and felt the slop was too much for me. So, I placed an index mark on the edge of the spacer where the tape began and found out that 3 revolutions of 3M Super33 black tape (used also for the Britain servos) created a very snug fit. I inserted the spacer by twisting the spacer into the roller and then trimmed off the excess tape. I haven’t installed the rollers yet but look forward to the improvement.

Bushings can’t be bought in the correct length? This should work and you save shipping by buying both at the same time. Grangier p/n 3ZM99
