• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

Hi,

I have to order a new 1 piece crankshaft seal for my Pitts S2S. ACS has 2 different which are for all direct drive Lycomings.( maybe there are more ) and the partnumbers are not matching withe the PN in the very old parts manual of the engine.

Maybe somebody can tell me, which I have to order..??

Many thanks in advance
