hub nut
Hello Bob, thank you for your answer. The nut is the big one on the rear hub, it measures 3" (76 mm) and is ocatagonal. I think the correct name for the wrench is box spanner but it could be a US definition. Enclose is the photo on C15A manual showing the wrench in use. Could you eventually get the wrench for me at a shop in Canada if you find it?
