Chris... the MS "dash" numbers are the same as the AN 900 "dash" numbers.

It's a MS3576-16 for a 1 inch ID.

See my earlier posts....

You can get the copper crush washers at Aircraft Spruce

A tip for A models. You might want to pull the mains up onto small ramps or something to get the plane level before draining the sump. I took out the screen at my condition inspection (after draining the oil) and a lot of oil came out of there making a nice mess. I think our A models tip back slightly and thus the sump isn't level.

Well Gil, I'm looking at the Spruce catalog and they show an AN900-16 as being equivalent to an MS35769-21. So I'm either going to have an ample supply of the right size or a bunch of shims for those uneven tables at the local restaurant. I'll know soon.

I'll bet a number of us builders (certainly me) did not know we needed to do this. So thanks for the education.

I attended a hands-on Lycoming workshop a year ago (a 2 day workshop on performing a 100 hourly on a Lycoming). Twelve guys attended and 7 of them were already flying and had been doing their own maintenance. Of those 7 who were flying only 3 of them had heard about the finger filter. The other 4 got a big shock when the instructor unscrewed the filter and removed it. Two of them had over 500 hours on their planes and had never removed the filter (because they didn't know it was there).

My guess is that a fairly large number of RV owners doing their own engine maintenence don't know about that filter. Come to think of it.....my guess is that a fairly large number of RV owners doing their own engine maintenance don't know a LOT of things that they should about FWF matters.

Chris, have you determined yet what the correct washer is? If anyone can confirm I need to order some. I'm one of those guys who didn't know you needed to check/clean this screen.

Also, I'm assuming it is the same for O-320-O-360 since they use the same case & sump, can anyone confirm?

AN900-16. I just checked my Spruce order from about six months ago when I ordered some...

May as well order some of those when I order the oil screen gaskets.

Anyone have this part number for this tabbed washer/gasket? I have not been able to find it called out anywhere.

Randy:

The AN900-16 is the one and can be ordered from Spruce. The Spruce catalog also lists it as an MS35769-21. The bag that arrived from Spruce was marked AN900-16 with no reference to the MS number.

The washer can be had at Wicks or Aircraft Spruce. If memory serves me, it is an an927-?
I always check the lower sump screen. Never know what you will find.
