Though I'd throw this out to the group.

Could anyone confirm or I.D. this sump and intake tubes I have, I was told they are from a IO-360 A1A. But none of the numbers match any of the Lyc parts manuals I have. But the sump looks identical to a friends sump with the LW-13864 part number.

The numbers on the sump are:
EQUIP 1 W 74664 REV D
19F6F

The intake tubes, I only have 3 of 4 are stamped: 74632, 74633, 73634.



Maybe the numbers are old or superseded? Any is info. appreciated, Paul

Have you tried to contact Lycoming?
Just a though.

you sure it's not a continental IO 360?

I'm going to try Lycoming tomorrow, looked through a bunch of parts catalogs and looks like the number change, or get superseded quite often.

It's definitely Lycoming it is identical to one on a friends Lyc. IO-360.

I'll figure it out eventually. Thanks for the input.

Well, turns out it was an Lyc. IO-360 sump I guess back in the old days there was no part number on the sump just casting numbers. This is a IO-360 A sump from the casting numbers. Thank you from those who looked in there parts books, on with the project.
