The International Cessna 170 Association

Jim, Taxi your plane to a point there is nothing blocking air-movement behind the airplane. LIke in the middle of a taxi way. I always face into the wind. Hold the brakes and go full throttle. Do not allow the plane to move. Look at the rpm developed. This is static rpm. For the McCauley 1A170 prop ...

Thank you, Gary, That helps a lot. It is amazing how a relatively simple part can have so many ideas and procedures associated with it. I printed a copy and will be handing it to my IA/AP to use a reference. Thanks Again Jim Collins N2488D C170B 1952 Just tell your A&P NOT to follow the parts s...

I would be if I still had my 170. I have the same amount of fear in an accident the thick glass cylinder would break as I do a metal can would be dented or deformed, breaking the seal and leaking gas all the same.

I'll confirm George is correct. It is a self reseting circuit breaker for the T&B and stall warning.

These seats are from a '56 172 but they are exactly the same as 170 seats in every way. They will fit any model of 170. The frames look to be in good condition but do have some rust at the bottom were the frame wraps around the seat rail. But I believe that will easily clean up. If I was looking for...

Those springs are not the Cessna "improved" springs best I can tell but springs found at Hillman hardware section. You won't be alone with locally procured parts in your latch. Amazing you found the pin in the door.

Another bit of advice. Before one does any disassembly of the latch at all, take about 10 pictures of it from all angles. You be glad you did. I'm the type of guy who can disassemble and reassemble about anything but these latches have beat me more than once and I've taken a few more than most apart...

If you have a picture of your instrument panel and the pull starter knob has been removed, this plane likely has an angle starter or a STC'd starter such as a B&C. Why not just ask what the engine has, I'd want to know. Top is the 0-300-A, B or C with straight starter, bottom is the 0-300-D with...

Woops. Looking at your pictures closer I see you didn't loose the pin that holds the latch and pin but the pin that holds the control rod to the latch. That is .100" diameter. best I can measure it, by .5" long and it looks to be brass in my sample. I wouldn't be afraid to use soft steel h...

It is a small piece of steel music wire .133" or between a #29 and #30 drill bit shank by 1" long. You could use a drill shank but they will rust. You could buy a piece of stainless steel from K&S Precision Metal. 1/8 will be to small, 5/32 .020 to large but you might be able to polish...

Someone could have done several things. The answer to your question an 0-300A never had a vacuum pad to install a pump in a stock configuration. The first place to look is your engine data plate. What is the serial number? Take a picture so we can see it. Look at your starter. Is the starter motor i...

Thanks, Guys- I was thinking one came from a B model. A quick measurement bolthole to bolt hole showed about 3/4" difference between struts. I think I have seen that A model dihedral is 1 degree while B model is 3 degrees so there's the difference. Got it sorted now. We always refer to the A m...

Just to wrap this up a bit. There are several part numbers you might find for a 5 hole C-145/300 accessory case. 628240, 627881A1 and maybe 530007. 530007 is the casting number you might find on the first two PN cases and sometimes it is referred to as a part number. These are the old original cases...

There’s been so many numbers and scenarios described in this thread that I’ve not been keeping up with it… But I can say that a “casting” number does not always (if ever) equate to a “part” number. Beware of that possibility. I agree, but it's so easy to get caught and we did early on in this story...

The owner says his maintenance co. says the part number was written inside and so there would be no way to identify it by outside marks. They say the cases are all the same until they are finished out. That I couldn't tell if the case was finished as a PN 641799 or the latest number PN 641800 for a ...
