Can someone tell me what size the oil drain plug (the one with the filter thingy on the back) crush washer size is so I can buy one before I take it out to change the oil? Mine appears to not be there at all and is leaking!
Thanks

From the SD 900 parts manual...
TAV13.18 0250.70.180 Washer - gasket id21 x od30 x 1.0 3
I measured one I have in a gasket kit and it is 27.8mm x 22.48mm x 1.06mm

If you're near a little airport, go into the Cessna parts dealer (or general light aircraft parts place) and get AN900-15 copper crush gaskets. Or get them from Aircraft Spruce online.

yes alloy for outside engine (sump screen, dipstick, engine bungs & gland nuts). The fiber ones are used on SOME plastic gland nuts, INSIDE your engine where there is a plastic nut INSIDE backing up the gland nut placed outside. I also use fiber washers on all outside places that have compromised threads along with teflon tape.
