    Sam, thanks for the video on the Bellanca. Any pictures from your project?

    Here in the NW, I have not had any problems with my baffle mounted cooler and over heating. I do need to completely block it off in the winter.

    Stephen, I was hoping the baffle mounted cooler would not need modification for winter flying. So this is not the case?
    I've got the old front mounted cooler and have this on my to do list to upgrade to an aluminum cooler on the baffle mount.
    What I'm seeing in this thread though is that baffle is not necessarily better than front?

    As far as the baffle mount, I have seen on a Van's RV where someone installed a sliding grated door that could be adjusted in the cockpit. I think that would be great if one could get it approved.

    just to chime in my 2 cents worth. Why do want to go through all of this trouble if it's not necessary ? We did the alternator conversion ( B&C specialties ) on my 55 Tripe and did not have to move anything. Given , it already had the flexible oil cooler lines . I believe another individual on this tread also did not have to do any cooler relocation. Just scratchin' my head ....

    So if you velcro the Van's shutters on, then no 337?

    Gentlemen,
    I have (on a PA22-150, O-320-A1A) a front mounted oil cooler, solid steel lines, and a 20amp (stock) generator. My ultimate goal is to convert to a larger (at least 50a) alternator. I've seen where people say that certain alternators may be installed without moving the oil cooler to the rear but with flexible oil lines. I've looked into making the lines flexible which would cost me at least $200 in parts. Is the advantage of moving the oil cooler worth the extra money (how much would it cost to move the oil cooler to the back... do these STC's, ie. Stewarts' STC, come with all of the components included or just the paperwork). I'm located in a FSDO that does not easily approve field approvals, therefore I'm looking for options that would be straight forward not requiring excessive paperwork. I realize this is a Oil Cooler Baffle thread but if anyone wants to comment on the alternator side of it too, I would appreciate some comments. To this point I have not had a problem with the oil cooler bracket breaking nor the steel oil lines leaking.
    Thanks
    Burk

    I already have the flexible lines on my plane,everywhere I read said you needed the a "rear mounted oil cooler" to get away with the alternator conversion...The Niagra cooler I bought was cheaper than "cub cooler" niagra sells and all I can eliminate 6 feet of oil hose and clean up the front of my plane...I'll post more results this summer once I get it back in the air flying again...

    I have the inter-av alternator with a front mount oil cooler. Flexible lines of course.
