Air Filter

[Bob Waldron]

I want to install an air filter on my 1940 BL-65 with a Lyc O-145. A Lycoming Service Bulliten recommends using a Chevrolet #15296265 which looks like one that I have seen on pre-war Chevrolets. I think that Taylorcraft also says to use the same filter on the L-2. I think that Franklin says to use the same filter on one of their early engines.

Unlike the Continental which has a flat airbox that faces forward and sits up on the 'chin' of the cowl, the Lycoming airbox comes straight down from the middle of the oil-pan and comes out of the cowl nearly half way back to the firewall.

I would like to put a legal filter on it, and one that did not look too out of place. I can get a 337. I would like to know what you Lyc O-145 folks are using and probably the Franklin folks too.

Get a FIELD APPROVAL to braze on a flange that will accept a Bracket air filter assembly. Tim

Re: Air Filter

I have the Chevy one on mine & the sheet from Lycoming on how to modify it. I like it because it keeps it all original. I ave pics in the owners photo album pg4 or 5 I believe.

Eric,

I can't see the picture real well, but I like what I see. I have the Lycoming drawing for the modification, but I don't have the air cleaner. Where would I go to find one?

Thanks.

Re: Air Filter

I would think there is a Chevy restoration club or web site. Let me know if you want a close up & I'll take one & e-mail it. Do you think the FAA would approve of a Chevy part now on a certified plane? That's what I like about the old planes,common parts & common sense.
