I doubt the gears have been heat-treated. It would seem like that would make the gears too hard and under load/stress the teeth would break easily.

Just as an add-on. When looking in the maintenance manual for grease with the required Molly percentage I couldn't find one, there is a grease with Molly infused but not at the percentage Mooney requires. So, I asked myself, that requirement was back in 1965 (I have a 65E with electric gear) and greases have changed over the decades so do I ignore the percentage difference? It's not that much more. Then I looked up Molly, what it does, and how it applies to Mooney. This is what I learned. The reason why Molly is used is to fill in the areas between the gear teeth. It's also used to reduce the wear of the gears. The grease with Molly is used in a high-pressure environment, like the sudden pressure placed on the gears when you select up or down. So, understanding the reason why Mooney wants a certain percentage of Molly/grease in that area, do you accept the off-the-shelf product or mix your own? If you mix your own, you have to now consider which particle size to use, the fine or coarse. Just a bit more to consider when talking about those two tiny little gears and what you are asking of them perhaps thousands of times! albert

Wasn't there a mention of placing a fuel filter by the Duke fuel pump?

I flew 5261B for 10 years. A good wax will keep the wings very slippery! There is another wood wing in a hangar at Hinkley Airport in Illinois, just west of ARR. It's ready to be picked up. The guy bought it for the engine.

It's too soon to know the longevity of the rollers I installed. The tracks are clean and the seats roll with ease. I like the idea of a metal bushing making contact with the bolt vs. just the molded part but it might not matter because how often are the seats being moved up and down the tracks? I would think the weight of the person in the seat impacts the roller's longevity most.

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)?
