Hi. I have a 29 rugby, I don,t know if its the same as the 27 but mine is in a kind of sleeve that slides over the shaft. the bearing is pressed into the end of the sleeve. Its a bit like on the ford modle A but a smaller version. I suspect this may not be original and may have been adapted at some stage but I am not sure. It works fine and I recently had the clutch relined so had it apart then. If it would help at all and you can't get a better answer let me know and I will take a photo and mail it to you.
