Inverted Oil System

[penguin]

Guys,

I am installing an inverted oil system in an O-360, and have wrecked the o-ring on the sump plug that goes on the end of the sump inlet coarse filter (Christen pt no 30002-001). The Christen instructions list the o-ring part no as 50004-111 (a Lycoming part no). Of course I can?t find anyone with one in stock.

Does anyone know of an alternate part number for a 50004-111 O-ring? Needs to be reasonably high temp as it sits at the bottom of the sump.

I wrecked the o-ring as I inserted it into sump bore ? it was a little stiff so I hit it with a mallet = shredded rubber! Any advice on how to avoid a similar fate 2nd time around?

Regards, Pete

Don't hit it with a mallet!

Inverted oil system on an "O" 360????

OK, I should have updated this a while ago, I found an alternate part number for the O-ring (I'll post it when I can remember what it is), put a little oil on, and it slid in like a charm. I think the old O-ring had become hard and expanded a little aftter stiing in the sump of the old engine for 10 years.

Yeah, an O-360-B1B fitted with an injector - trying to emphasize its a deep sump, not an M1B style sump (although it might not make a difference).

For what its worth, I modified my Superior sump a few months ago. I took some photos to help others if needs be. I had to do it kinda blind hoping things would work out. Surprisingly straightforward when I went at it.

I was most worried about the plug, but it fit perfectly and easily. The hardest part was making the hoses.
