This is exactly what's going on with my 1970 at1. Time to order those crank seals. Thanks for posting this video!

remember no oil in the trans except mix or injection oil. Your on it. Thanks for the video. BTW, I built a tool to remove the dynamo.

My at2 is doing this and it drank so much oil it starved the gearbox so now I get to replace bearings too 😭
