Most alternators have solid state regulators which are pretty accurate. Your 14.5 volts is correct. It's possible that your old gen system regulator was set low, so the comparison may not be valid. True, if the output equals the draw, then with a fully charged battery then eventually your ammeter sh...

George, how is your carpet held down? I am embarrassed to say that I still have the original carpet. The rear half is glued, and the forward half has screws along the edge to allow access to inspection holes. I am getting ready to replace the carpet and would like some alternatives. (Or maybe it'll ...

Steve, it looks to me like it's doing what it's supposed to! After you use the battery to make an engine start, even with nothing else online, the battery wants to be replenished, so that's what your alternator is doing! Later inflight, you've got other appliances on and your alternator is supplying...

Good questions, Harold! This very series was asked by me of my Avionics Inspector at the SAT FSDO. Here's what he said. Opinions vary on this, but the FAA position is that radio installations, if included as original installations from the mfr., do not require Form 337's (Major Alterations and Repai...

The H engine has a valve near the left front oil gallery that controls oil flow to the special crankcase gallery. I'm reluctant to call it a "damper" because I've never heard it called that and I'm afraid some may confuse that with a dampened crankshaft, ...entirely different parts, locati...

Avemco is not only not competitive pricewise, they have horrible office procedures. They are frequently telling me I'm cancelled about 30 days AFTER I've renewed. Their left hand and their right hands are not even on the same BODY! When this policy expires, I'm gong DIRECT to AIG, as we discussed pr...

Like george said,the D in the serial number indicates a dampened crankshaft--meaning it has centrifugal counterweights to make it run smoother. The earliest C-145's as well as the C-125's didn't have this feature. The H in the model number indicates a dampered (not dampened) crank,this would be a s...

http://www.popav.com/Cessna170/ is the link I found. I know nothing about it, so post your pics there at your own risk.

Why don't you post your pics at http://www.popav.com and link it this this topic here, so we can see them? gh

lowNslow wrote:Could it be that the Aero-Matic prop requires a dampened crankshaft - I thought that was what the "H" stood for.

The "H" stands for hydraulic crankshaft and crankcase. A dampened crankshaft is denoted by a letter "D" within the engine serial number.

It's a good idea when doing this trick to remember a few things. 1) Manila, cotton, or nylon rope is less likely to contain damaging trash to introduce into your cylinder or damage a piston, etc., especially if new rope. 2) When bringing the piston up against the valve, be gentle. You don't want to ...

I think it's necessary in airplanes like 170's to conserve valuable panel-space so that's what I have uppermost in my mind when I think about radios. Therefore I believe you should consider a Narco Nav 122 either new or used, if you want to not take up any additional space than an instrument hole. Y...

For some marvelous reason, I had quit using Marvel when I switched to car gas a few months ago!!!! George, how in the world do you figure you are ahead of me? I went to several TX fly-ins looking for you, and the only one you have showed up at was the one I did not make! Yes, Everyone noticed that ...

Eric, look at the MX Library for a more detailed description of the Aeromatic prop and Beech Roby Props. In answer to your question regarding the "H" engine, I believe it's going to be another case of coincidence. The Aeromatic does not use hydraulics whatsoever, but the -2H engine may hav...

Who you callin' SLOW, Joe? Like Brother Dave Gardner once said, "I may be slow (not really-gh) , but I'm ahead of YOU!!"
