Lycoming part # LW15070 3 1/2 x 7/64

You might try and call Tom Schmidt, looks like he's had them in the past.
Schmidt Aviation Inc.
Ft Lauderdale, Fl 33309
954-772-0772

If not, these guys claim 2-3 days . . .

Well hate to say Lycoming specs r wrong..pulled oil pump off & measured o-ring id & it's not 3.50 it's 3.75..so thought maybe o-ring was outta whack & measured pump where o-ring goes & it's 3.75 Id,i found a 3.50..that wouldn't even come close to working

Wow, had no way of anticipating that. :dontknow:
Sure glad you didn't order one and then find that out 34 days later. :violent1:

So, was Tom able to hook you up or are you still needing one?

For what it's worth, what you need looks to be dash240 which is Grainger's item number 41UM76.

They don't have them in Ocala, but claim a fat week to get them. The 5 pack is < Lycoming's single price.
There used to be one in W Melbourne, although I don't know that it's still there. Maybe they have them?

I wouldn't think 15 thousandths would be a deal breaker in 4 inches.
But then I don't have mine apart to look at it either. :dontknow:

If you are thinking the size can be fudged a little, you might try part number MS28775-240 (1/8 x 3.75 x 4). I haven't checked but I would think an auto parts or hydraulic shop would be able to match that up otherwise it's ~$1.25 plus shipping from aircraft vendors and should be readily available.

You are wasting your time talking to the people who work the counter at Grainger. Get the book or look up on line.
