The International Cessna 170 Association

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 ...

It has been an adventure trying to help this individual through language barriers and his physical limit of blindness. Email is interpreted for us both ways but it certainly is far from perfect. We have often gone over the same info several times. And I can't just send a picture with an arrow pointi...

The tach drive turning in reverse will be corrected 90° gear box adapter is installed. It is a PN on page 18 (and also for the IO-360 case). Oil pressure now matches that from the report from the overhauler. Probably had something to do with the fact the overhauler didn't have a filter adapter and a...

And update. The engine owner is very confident his overhauler built this engine to meet EASA standards as they were contracted to do. He doesn't seem to have any paperwork that explains how a IO-360 ES sump would be approved on an 0-300. I've highly suggested he get that documentation from his overh...

Gary, thank you thank you for the excellent photos of the sump with those sticks through the ports of the sump and then extending them through the sump. I don't have a sump on hand and have been trying to imagine it from the illustrations, an impossible task. And I can even emagine how the oil gets ...

Looks like the pressure relief valve is moved to the other side of the acc case, could that mean the flow through the engine is reversed? Reversed only within the accy-case…not the engine. (actually… the NS accy case is more straight-forward …it is the OS accy case which reversed the oil flow from ...
