The International Cessna 170 Association

The original 170,s and 170a all had the plenum chambers over the cylinders and the later 170b,s went to the pressure cowl. I had a 170a with the plenum chamber and couldn’t wait to go to the pressure cowl when I fitted the 4 banger. That was a big mistake . The plenum chamber is the most efficient ...

The IPC would illustrate it fairly well. You’ll need that IPC if you plan to do this conversion anyway. I have both IPC’s. I guess I didn’t ask correctly, as long as both cowls close off the airflow at the front either will work. Just wondering if anyone has done this before. Cessna did it... :wink...

Does anyone have a picture of the later versions they could share?

Sealed area at front.

I’m fairly sure the newer cowl would fit the airplane and engine, but you’d also have to change the baffling too. The cooling system changed completely between ‘52 and ‘53. My thinking as well. The early versions had the internal cylinder wrap around baffles and the sealed area is located at the fr...

The cowls on my 48 are fairly worn and almost beyond economic repair. I have a set of 53 cowls, they are slightly different. Question, can they be switched out and is that approved? Yes the 53 has both access doors on the upper cowl.

Finally got around to installing the Bartone pipes, it was time. The install took the better part of the day, including a test flight......Like everything in the aircraft maintenance world.. there are no 5 minute jobs!! Sound is a little quieter, cowl looks better, (no photo, I forgot to take one) I...

I can not stress this enough. Pat and Sybil ARE NOT computer people. Yes they have an email address and offered it. I have sent and received email from Sybil but a phone call was always part of the equation. I get the impression checking email on an hourly bases or maybe even a daily bases, is not ...

Did you do that through Sybil's email address? Wondering because I did not hear back yet. Thanks

I've placed this ad for Pat and Sybil. From Sybil: BARTONE STACKS can be available within a month if there is enough interest. Due to increases in material and postage, the new price is $688. Since I have to order 20 sets at a time, I would like to know if there is enough interest prior to placing ...

Advantage I've heard: Keeps cowl cleaner. Makes cowl removal easier. Less drag thus more speed Less sound or nicer sound in the cabin. Less CO2 in the cabin. Pretty easy to see #1. If your current fangs make your cowl hard to remove/reinstall, you will see how #2 could work. If you understand drag ...

Excellent. Thanks George

Although it doesn't appear obvious there is a safe gap between the heater hose and the fuel line. You can see the heater hose is held by the large Adel clamp. You might want to try this set up to avoid fuel line chaffing.

Sorry this took so long. Here are some pictures of my jury struts. Prior to installing them make sure you install some packing tape in order to prevent chaffing.
