Probably a correct analysis.
I find this is another use for the workshop press that no-one had a good word for a couple of years ago. Protect the pulley thread with a nut, support the inner diameter of the gear, close to the boss and press the end of the camshaft square and hard............BANG! Off it comes in seconds. But it does mean the camshaft and gear assembly has to be out of the engine though....
