I've now got about 10 Phase I flight hours on my Kitfox's new/old greyhead 582. It has one of the original C gearboxes. Apparently Rotax made an early design change to the spider and propeller shaft seal but mine was not updated.
My seal is leaking gear oil (about 5-10 CC/hr). My local Rotax service center told me it would likely leak a bit for the first 15 hours but then tighten up. I'm dubious. In any case, I was told the original seal is no longer available from Rotax. Does anyone have information on a part number or where I might be able to get a replacement? It would seem ridiculous to have to replace a low-time gearbox just for a seal.
