Gettin' Gaskety 2: 78-83 Honda PA50 Tran Cover

So since I've had my 1980 Honda PA50 in my apartment, I've had
this transmission leak in the rear wheel. From what I could tell it is
the old gasket that is to blame. I'm sure sitting with oil in it for 30
years makes old asbestos gaskets weak.


I researched all my usual OEM Honda parts suppliers and this
transmission cover gasket is listed as out of stock or discontinued.


So I decided to go my own route and make a precision gasket myself.
I scanned in the transmission cover into Photoshop, traced it in
Illustrator, and checked my measurements with my digital micrometer.


I then printed my .pdf and spray mounted it to the back of a sheet of
gasket paper. Then I cut with scissors, a hole punch, and my Xacto
knife.


It's a somewhat tedious process but results are perfect every time!


So to save you the energy of drawing this yourself, I've posted the
.pdf of my gasket on my website here. I'm pretty sure this works for
1978-83 Honda Hobbits and PA50s, as well as some Caminos. The
vectors are preserved in the .pdf, so feel free to make adjustments
as needed.

Also, check what came in the mail today!


Still waiting for my Proma pipe and ZA50 performance crank to arrive
at Orphanage. It's getting down to the wire. It's been close to 70
degrees temperature here all week in Brooklyn. I need to button up
these bikes and get them on the road ASAP!

  1. hey man, excellent share, thanks for posting that up i'll b e sure to ttake advantage of your research. did you know that if the gearbox is stored at the wrong angle it will leak naturally? it has to stay upright to hold oil, but if the gasket was actually bad then thats a whole other story.

  3. Awesome. Noted. However it was leaking quite a bit just mounted to my Hobbit while it stood upright in my apt. Hope it's not a hidden seal somewhere behind the axle.
