A-65 Oil screen thread pitch?

[Scott[_1_]]

Doe anybody know what the thread pitch for the oil screen is on a
Continental A-65? I have slightly boogered threads on the engine
threads and I want to run a set of dies through (I bought a tool with
the dies from McMaster Carr). It looks like 16 TPI is the closest.
Does that sound reasonable or does someone know for sure? I checked all
the ones that came with the tool by putting them over the threads on the
oil screen and let them drop in between the threads. Is that an
acceptable way to test for the right pitch or do I need to drop them
into the (female) threads in the rear accesory case, which would be damn
near impossible to see if they line up perfectly)? Any other ideas
(trying to avoid pulling the engine or rear case off)???

What kind of tool did you get with your dies. What you need is a simple
"thread pitch gage" to be sure. Inexpensive ones can be purchased from most
any place that sells measuring tools to machine shops.

I machined a plug for remote oil filter.
I confirm 16TPI.

I can't remember the exact name of the tool, but it's made to repair
internal threads that are damaged. Basically looks similar to a piston
ring expander with changeable dies that attach at the ends. Then all
you do is set the dies into the threads, squeeze the handle a bit to
give the dies some pressure to stay in the threads and spin the tool around.

Thanks for the info! I think it probably would be good to get a pitch
gauge as well and triple check. Besides, I'm SURE there will be other
places I could use the gauge...But it is nice to get that fuzzy feeling
from someone else confirming what I see here. Thanks again...

Scott,

It is called a "Therad Chaser" they make them in all sizes ... you may
find them at Enco.com or other machine catalogs.

Actually, I'm not sure they actually called it that in their catalog,
but that's essentially what it is. Anyhow...I got the threads repaired
yesterday, so I'm ready to button up and test run it. Thanks to all for
the help...

El Reno Aviation has a tap to fit wich they rent/loan it to F&M STC filter

Maybe call them?

Thanks for the tip. I bought a tool from McMaster-Carr for repairing
internal threads and it did the trick....
